All Implemented Interfaces:: java.sql.PreparedStatement, java.sql.Statement

Direct Known Subclasses:: JdbcCallableStatement

public class JdbcPreparedStatement
extends java.lang.Object
implements java.sql.PreparedStatement
extends java.lang.Object
implements java.sql.PreparedStatement

An object that represents a precompiled SQL statement.

A SQL statement is precompiled and stored in a PreparedStatement object. This object can then be used to efficiently execute this statement multiple times.

Note: The setter methods (setShort, setString, and so on) for setting IN parameter values must specify types that are compatible with the defined SQL type of the input parameter. For instance, if the IN parameter has SQL type INTEGER, then the method setInt should be used.

If arbitrary parameter type conversions are required, the method setObject should be used with a target SQL type.

In the following example of setting a parameter, con represents an active connection:

   PreparedStatement pstmt = con.prepareStatement("UPDATE EMPLOYEES
                                     SET SALARY = ? WHERE ID = ?");
   pstmt.setBigDecimal(1, 153833.00)
   pstmt.setInt(2, 110592)

Constructor Detail

JdbcPreparedStatement

public JdbcPreparedStatement(java.sql.PreparedStatement pstmt)

Method Detail

executeQuery

public java.sql.ResultSet executeQuery(java.lang.String sql)
                                throws java.sql.SQLException

Executes the given SQL statement, which returns a single ResultSet object.

Specified by:: executeQuery in interface java.sql.Statement

Parameters:: sql - an SQL statement to be sent to the database, typically a static SQL SELECT statement
Returns:: a ResultSet object that contains the data produced by the given query; never null
Throws:: java.sql.SQLException - if a database access error occurs or the given SQL statement produces anything other than a single ResultSet object

executeUpdate

public int executeUpdate(java.lang.String sql)
                  throws java.sql.SQLException

Executes the given SQL statement, which may be an INSERT, UPDATE, or DELETE statement or an SQL statement that returns nothing, such as an SQL DDL statement.

Specified by:: executeUpdate in interface java.sql.Statement

Parameters:: sql - an SQL INSERT, UPDATE or DELETE statement or an SQL statement that returns nothing
Returns:: either the row count for INSERT, UPDATE or DELETE statements, or 0 for SQL statements that return nothing
Throws:: java.sql.SQLException - if a database access error occurs or the given SQL statement produces a ResultSet object

close

public void close()
           throws java.sql.SQLException

Releases this Statement object's database and JDBC resources immediately instead of waiting for this to happen when it is automatically closed. It is generally good practice to release resources as soon as you are finished with them to avoid tying up database resources.

Calling the method close on a Statement object that is already closed has no effect.

Note: A Statement object is automatically closed when it is garbage collected. When a Statement object is closed, its current ResultSet object, if one exists, is also closed.

Specified by:: close in interface java.sql.Statement

Throws:: java.sql.SQLException - if a database access error occurs

getMaxFieldSize

public int getMaxFieldSize()
                    throws java.sql.SQLException

Retrieves the maximum number of bytes that can be returned for character and binary column values in a ResultSet object produced by this Statement object. This limit applies only to BINARY, VARBINARY, LONGVARBINARY, CHAR, VARCHAR, and LONGVARCHAR columns. If the limit is exceeded, the excess data is silently discarded.

Specified by:: getMaxFieldSize in interface java.sql.Statement

Returns:: the current column size limit for columns storing character and binary values; zero means there is no limit
Throws:: java.sql.SQLException - if a database access error occurs
See Also:: setMaxFieldSize(int)

setMaxFieldSize

public void setMaxFieldSize(int max)
                     throws java.sql.SQLException

Sets the limit for the maximum number of bytes in a ResultSet column storing character or binary values to the given number of bytes. This limit applies only to BINARY, VARBINARY, LONGVARBINARY, CHAR, VARCHAR, and LONGVARCHAR fields. If the limit is exceeded, the excess data is silently discarded. For maximum portability, use values greater than 256.

Specified by:: setMaxFieldSize in interface java.sql.Statement

Parameters:: max - the new column size limit in bytes; zero means there is no limit
Throws:: java.sql.SQLException - if a database access error occurs or the condition max >= 0 is not satisfied
See Also:: getMaxFieldSize()

getMaxRows

public int getMaxRows()
               throws java.sql.SQLException

Retrieves the maximum number of rows that a ResultSet object produced by this Statement object can contain. If this limit is exceeded, the excess rows are silently dropped.

Specified by:: getMaxRows in interface java.sql.Statement

Returns:: the current maximum number of rows for a ResultSet object produced by this Statement object; zero means there is no limit
Throws:: java.sql.SQLException - if a database access error occurs
See Also:: setMaxRows(int)

setMaxRows

public void setMaxRows(int max)
                throws java.sql.SQLException

Sets the limit for the maximum number of rows that any ResultSet object can contain to the given number. If the limit is exceeded, the excess rows are silently dropped.

Specified by:: setMaxRows in interface java.sql.Statement

Parameters:: max - the new max rows limit; zero means there is no limit
Throws:: java.sql.SQLException - if a database access error occurs or the condition max >= 0 is not satisfied
See Also:: getMaxRows()

setEscapeProcessing

public void setEscapeProcessing(boolean enable)
                         throws java.sql.SQLException

Sets escape processing on or off. If escape scanning is on (the default), the driver will do escape substitution before sending the SQL statement to the database. Note: Since prepared statements have usually been parsed prior to making this call, disabling escape processing for PreparedStatements objects will have no effect.

Specified by:: setEscapeProcessing in interface java.sql.Statement

Parameters:: enable - true to enable escape processing; false to disable it
Throws:: java.sql.SQLException - if a database access error occurs

getQueryTimeout

public int getQueryTimeout()
                    throws java.sql.SQLException

Retrieves the number of seconds the driver will wait for a Statement object to execute. If the limit is exceeded, a SQLException is thrown.

Specified by:: getQueryTimeout in interface java.sql.Statement

Returns:: the current query timeout limit in seconds; zero means there is no limit
Throws:: java.sql.SQLException - if a database access error occurs
See Also:: setQueryTimeout(int)

setQueryTimeout

public void setQueryTimeout(int seconds)
                     throws java.sql.SQLException

Sets the number of seconds the driver will wait for a Statement object to execute to the given number of seconds. If the limit is exceeded, an SQLException is thrown.

Specified by:: setQueryTimeout in interface java.sql.Statement

Parameters:: seconds - the new query timeout limit in seconds; zero means there is no limit
Throws:: java.sql.SQLException - if a database access error occurs or the condition seconds >= 0 is not satisfied
See Also:: getQueryTimeout()

cancel

public void cancel()
            throws java.sql.SQLException

Cancels this Statement object if both the DBMS and driver support aborting an SQL statement. This method can be used by one thread to cancel a statement that is being executed by another thread.

Specified by:: cancel in interface java.sql.Statement

Throws:: java.sql.SQLException - if a database access error occurs

getWarnings

public java.sql.SQLWarning getWarnings()
                                throws java.sql.SQLException

Retrieves the first warning reported by calls on this Statement object. Subsequent Statement object warnings will be chained to this SQLWarning object.

The warning chain is automatically cleared each time a statement is (re)executed. This method may not be called on a closed Statement object; doing so will cause an SQLException to be thrown.

Note: If you are processing a ResultSet object, any warnings associated with reads on that ResultSet object will be chained on it rather than on the Statement object that produced it.

Specified by:: getWarnings in interface java.sql.Statement

Returns:: the first SQLWarning object or null if there are no warnings
Throws:: java.sql.SQLException - if a database access error occurs or this method is called on a closed statement

clearWarnings

public void clearWarnings()
                   throws java.sql.SQLException

Clears all the warnings reported on this Statement object. After a call to this method, the method getWarnings will return null until a new warning is reported for this Statement object.

Specified by:: clearWarnings in interface java.sql.Statement

Throws:: java.sql.SQLException - if a database access error occurs

setCursorName

public void setCursorName(java.lang.String name)
                   throws java.sql.SQLException

Sets the SQL cursor name to the given String, which will be used by subsequent Statement object execute methods. This name can then be used in SQL positioned update or delete statements to identify the current row in the ResultSet object generated by this statement. If the database does not support positioned update/delete, this method is a noop. To insure that a cursor has the proper isolation level to support updates, the cursor's SELECT statement should have the form SELECT FOR UPDATE. If FOR UPDATE is not present, positioned updates may fail.

Note: By definition, the execution of positioned updates and deletes must be done by a different Statement object than the one that generated the ResultSet object being used for positioning. Also, cursor names must be unique within a connection.

Specified by:: setCursorName in interface java.sql.Statement

Parameters:: name - the new cursor name, which must be unique within a connection
Throws:: java.sql.SQLException - if a database access error occurs

execute

public boolean execute(java.lang.String sql)
                throws java.sql.SQLException

Executes the given SQL statement, which may return multiple results. In some (uncommon) situations, a single SQL statement may return multiple result sets and/or update counts. Normally you can ignore this unless you are (1) executing a stored procedure that you know may return multiple results or (2) you are dynamically executing an unknown SQL string.

The execute method executes an SQL statement and indicates the form of the first result. You must then use the methods getResultSet or getUpdateCount to retrieve the result, and getMoreResults to move to any subsequent result(s).

Specified by:: execute in interface java.sql.Statement

Parameters:: sql - any SQL statement
Returns:: true if the first result is a ResultSet object; false if it is an update count or there are no results
Throws:: java.sql.SQLException - if a database access error occurs
See Also:: getResultSet(), getUpdateCount(), getMoreResults()

getResultSet

public java.sql.ResultSet getResultSet()
                                throws java.sql.SQLException

Retrieves the current result as a ResultSet object. This method should be called only once per result.

Specified by:: getResultSet in interface java.sql.Statement

Returns:: the current result as a ResultSet object or null if the result is an update count or there are no more results
Throws:: java.sql.SQLException - if a database access error occurs
See Also:: execute(java.lang.String)

getUpdateCount

public int getUpdateCount()
                   throws java.sql.SQLException

Retrieves the current result as an update count; if the result is a ResultSet object or there are no more results, -1 is returned. This method should be called only once per result.

Specified by:: getUpdateCount in interface java.sql.Statement

Returns:: the current result as an update count; -1 if the current result is a ResultSet object or there are no more results
Throws:: java.sql.SQLException - if a database access error occurs
See Also:: execute(java.lang.String)

getMoreResults

public boolean getMoreResults()
                       throws java.sql.SQLException

Moves to this Statement object's next result, returns true if it is a ResultSet object, and implicitly closes any current ResultSet object(s) obtained with the method getResultSet.

There are no more results when the following is true:

     // stmt is a Statement object
     ((stmt.getMoreResults() == false) && (stmt.getUpdateCount() == -1))

Specified by:: getMoreResults in interface java.sql.Statement

Returns:: true if the next result is a ResultSet object; false if it is an update count or there are no more results
Throws:: java.sql.SQLException - if a database access error occurs
See Also:: execute(java.lang.String)

setFetchDirection

public void setFetchDirection(int direction)
                       throws java.sql.SQLException

Gives the driver a hint as to the direction in which rows will be processed in ResultSet objects created using this Statement object. The default value is ResultSet.FETCH_FORWARD.

Note that this method sets the default fetch direction for result sets generated by this Statement object. Each result set has its own methods for getting and setting its own fetch direction.

Specified by:: setFetchDirection in interface java.sql.Statement

Parameters:: direction - the initial direction for processing rows
Throws:: java.sql.SQLException - if a database access error occurs or the given direction is not one of ResultSet.FETCH_FORWARD, ResultSet.FETCH_REVERSE, or ResultSet.FETCH_UNKNOWN
Since:: 1.2
See Also:: getFetchDirection()

getFetchDirection

public int getFetchDirection()
                      throws java.sql.SQLException

Retrieves the direction for fetching rows from database tables that is the default for result sets generated from this Statement object. If this Statement object has not set a fetch direction by calling the method setFetchDirection, the return value is implementation-specific.

Specified by:: getFetchDirection in interface java.sql.Statement

Returns:: the default fetch direction for result sets generated from this Statement object
Throws:: java.sql.SQLException - if a database access error occurs
Since:: 1.2
See Also:: setFetchDirection(int)

setFetchSize

public void setFetchSize(int rows)
                  throws java.sql.SQLException

Gives the JDBC driver a hint as to the number of rows that should be fetched from the database when more rows are needed. The number of rows specified affects only result sets created using this statement. If the value specified is zero, then the hint is ignored. The default value is zero.

Specified by:: setFetchSize in interface java.sql.Statement

Parameters:: rows - the number of rows to fetch
Throws:: java.sql.SQLException - if a database access error occurs, or the condition 0 <= rows <= this.getMaxRows() is not satisfied.
Since:: 1.2
See Also:: getFetchSize()

getFetchSize

public int getFetchSize()
                 throws java.sql.SQLException

Retrieves the number of result set rows that is the default fetch size for ResultSet objects generated from this Statement object. If this Statement object has not set a fetch size by calling the method setFetchSize, the return value is implementation-specific.

Specified by:: getFetchSize in interface java.sql.Statement

Returns:: the default fetch size for result sets generated from this Statement object
Throws:: java.sql.SQLException - if a database access error occurs
Since:: 1.2
See Also:: setFetchSize(int)

Since:: 1.2

addBatch

public void addBatch(java.lang.String sql)
              throws java.sql.SQLException

Adds the given SQL command to the current list of commmands for this Statement object. The commands in this list can be executed as a batch by calling the method executeBatch.

NOTE: This method is optional.

Specified by:: addBatch in interface java.sql.Statement

Parameters:: sql - typically this is a static SQL INSERT or UPDATE statement
Throws:: java.sql.SQLException - if a database access error occurs, or the driver does not support batch updates
Since:: 1.2
See Also:: executeBatch()

clearBatch

public void clearBatch()
                throws java.sql.SQLException

Empties this Statement object's current list of SQL commands.

NOTE: This method is optional.

Specified by:: clearBatch in interface java.sql.Statement

Throws:: java.sql.SQLException - if a database access error occurs or the driver does not support batch updates
Since:: 1.2
See Also:: addBatch(java.lang.String)

executeBatch

public int[] executeBatch()
                   throws java.sql.SQLException

Submits a batch of commands to the database for execution and if all commands execute successfully, returns an array of update counts. The int elements of the array that is returned are ordered to correspond to the commands in the batch, which are ordered according to the order in which they were added to the batch. The elements in the array returned by the method executeBatch may be one of the following:

A number greater than or equal to zero -- indicates that the command was processed successfully and is an update count giving the number of rows in the database that were affected by the command's execution
A value of SUCCESS_NO_INFO -- indicates that the command was processed successfully but that the number of rows affected is unknown
If one of the commands in a batch update fails to execute properly, this method throws a BatchUpdateException, and a JDBC driver may or may not continue to process the remaining commands in the batch. However, the driver's behavior must be consistent with a particular DBMS, either always continuing to process commands or never continuing to process commands. If the driver continues processing after a failure, the array returned by the method BatchUpdateException.getUpdateCounts will contain as many elements as there are commands in the batch, and at least one of the elements will be the following:
A value of EXECUTE_FAILED -- indicates that the command failed to execute successfully and occurs only if a driver continues to process commands after a command fails

A driver is not required to implement this method. The possible implementations and return values have been modified in the Java 2 SDK, Standard Edition, version 1.3 to accommodate the option of continuing to proccess commands in a batch update after a BatchUpdateException obejct has been thrown.

Specified by:: executeBatch in interface java.sql.Statement

Returns:: an array of update counts containing one element for each command in the batch. The elements of the array are ordered according to the order in which commands were added to the batch.
Throws:: java.sql.SQLException - if a database access error occurs or the driver does not support batch statements. Throws BatchUpdateException (a subclass of SQLException) if one of the commands sent to the database fails to execute properly or attempts to return a result set.
Since:: 1.3

public java.sql.Connection getConnection()
                                  throws java.sql.SQLException

Retrieves the Connection object that produced this Statement object.

Specified by:: getConnection in interface java.sql.Statement

Returns:: the connection that produced this statement

clearParameters

public void clearParameters()
                     throws java.sql.SQLException

Clears the current parameter values immediately.

In general, parameter values remain in force for repeated use of a statement. Setting a parameter value automatically clears its previous value. However, in some cases it is useful to immediately release the resources used by the current parameter values; this can be done by calling the method clearParameters.

Specified by:: clearParameters in interface java.sql.PreparedStatement

Throws:: java.sql.SQLException - if a database access error occurs

setObject

public void setObject(int parameterIndex,
                      java.lang.Object x,

                      int scale)
               throws java.sql.SQLException

Sets the value of the designated parameter with the given object. The second argument must be an object type; for integral values, the java.lang equivalent objects should be used.

The given Java object will be converted to the given targetSqlType before being sent to the database. If the object has a custom mapping (is of a class implementing the interface SQLData), the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, Struct, or Array, the driver should pass it to the database as a value of the corresponding SQL type.

Note that this method may be used to pass database-specific abstract data types.

Specified by:: setObject in interface java.sql.PreparedStatement

Parameters:: parameterIndex - the first parameter is 1, the second is 2, ...; x - the object containing the input parameter value; targetSqlType - the SQL type (as defined in java.sql.Types) to be sent to the database. The scale argument may further qualify this type.; scale - for java.sql.Types.DECIMAL or java.sql.Types.NUMERIC types, this is the number of digits after the decimal point. For all other types, this value will be ignored.
Throws:: java.sql.SQLException - if a database access error occurs
See Also:: Types

setObject

public void setObject(int parameterIndex,
                      java.lang.Object x,
                      int targetSqlType)
               throws java.sql.SQLException

Sets the value of the designated parameter with the given object. This method is like the method setObject above, except that it assumes a scale of zero.

Specified by:: setObject in interface java.sql.PreparedStatement

Parameters:: parameterIndex - the first parameter is 1, the second is 2, ...; x - the object containing the input parameter value; targetSqlType - the SQL type (as defined in java.sql.Types) to be sent to the database
Throws:: java.sql.SQLException - if a database access error occurs

setObject

public void setObject(int parameterIndex,
                      java.lang.Object x)
               throws java.sql.SQLException

Sets the value of the designated parameter using the given object. The second parameter must be of type Object; therefore, the java.lang equivalent objects should be used for built-in types.

The JDBC specification specifies a standard mapping from Java Object types to SQL types. The given argument will be converted to the corresponding SQL type before being sent to the database.

Note that this method may be used to pass datatabase- specific abstract data types, by using a driver-specific Java type. If the object is of a class implementing the interface SQLData, the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, Struct, or Array, the driver should pass it to the database as a value of the corresponding SQL type.

This method throws an exception if there is an ambiguity, for example, if the object is of a class implementing more than one of the interfaces named above.

Specified by:: setObject in interface java.sql.PreparedStatement

Parameters:: parameterIndex - the first parameter is 1, the second is 2, ...; x - the object containing the input parameter value
Throws:: java.sql.SQLException - if a database access error occurs or the type of the given object is ambiguous

execute

public boolean execute()
                throws java.sql.SQLException

Executes the SQL statement in this PreparedStatement object, which may be any kind of SQL statement. Some prepared statements return multiple results; the execute method handles these complex statements as well as the simpler form of statements handled by the methods executeQuery and executeUpdate.

The execute method returns a boolean to indicate the form of the first result. You must call either the method getResultSet or getUpdateCount to retrieve the result; you must call getMoreResults to move to any subsequent result(s).

Specified by:: execute in interface java.sql.PreparedStatement

Returns:: true if the first result is a ResultSet object; false if the first result is an update count or there is no result
Throws:: java.sql.SQLException - if a database access error occurs or an argument is supplied to this method

Specified by:: setArray in interface java.sql.PreparedStatement

Parameters:: i - the first parameter is 1, the second is 2, ...; x - an Array object that maps an SQL ARRAY value
Throws:: java.sql.SQLException - if a database access error occurs
Since:: 1.2

getMetaData

public java.sql.ResultSetMetaData getMetaData()
                                       throws java.sql.SQLException

Retrieves a ResultSetMetaData object that contains information about the columns of the ResultSet object that will be returned when this PreparedStatement object is executed.

Because a PreparedStatement object is precompiled, it is possible to know about the ResultSet object that it will return without having to execute it. Consequently, it is possible to invoke the method getMetaData on a PreparedStatement object rather than waiting to execute it and then invoking the ResultSet.getMetaData method on the ResultSet object that is returned.

NOTE: Using this method may be expensive for some drivers due to the lack of underlying DBMS support.

Specified by:: getMetaData in interface java.sql.PreparedStatement

Returns:: the description of a ResultSet object's columns or null if the driver cannot return a ResultSetMetaData object
Throws:: java.sql.SQLException - if a database access error occurs
Since:: 1.2

setDate

public void setDate(int parameterIndex,
                    java.sql.Date x,
                    java.util.Calendar cal)
             throws java.sql.SQLException

Sets the designated parameter to the given java.sql.Date value, using the given Calendar object. The driver uses the Calendar object to construct an SQL DATE value, which the driver then sends to the database. With a Calendar object, the driver can calculate the date taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.

Specified by:: setDate in interface java.sql.PreparedStatement

Parameters:: parameterIndex - the first parameter is 1, the second is 2, ...; x - the parameter value; cal - the Calendar object the driver will use to construct the date
Throws:: java.sql.SQLException - if a database access error occurs
Since:: 1.2

setTime

public void setTime(int parameterIndex,
                    java.sql.Time x,
                    java.util.Calendar cal)
             throws java.sql.SQLException

Sets the designated parameter to the given java.sql.Time value, using the given Calendar object. The driver uses the Calendar object to construct an SQL TIME value, which the driver then sends to the database. With a Calendar object, the driver can calculate the time taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.

Specified by:: setTime in interface java.sql.PreparedStatement

Parameters:: parameterIndex - the first parameter is 1, the second is 2, ...; x - the parameter value; cal - the Calendar object the driver will use to construct the time
Throws:: java.sql.SQLException - if a database access error occurs
Since:: 1.2

setTimestamp

public void setTimestamp(int parameterIndex,
                         java.sql.Timestamp x,
                         java.util.Calendar cal)
                  throws java.sql.SQLException

Sets the designated parameter to the given java.sql.Timestamp value, using the given Calendar object. The driver uses the Calendar object to construct an SQL TIMESTAMP value, which the driver then sends to the database. With a Calendar object, the driver can calculate the timestamp taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.

Specified by:: setTimestamp in interface java.sql.PreparedStatement

Parameters:: parameterIndex - the first parameter is 1, the second is 2, ...; x - the parameter value; cal - the Calendar object the driver will use to construct the timestamp
Throws:: java.sql.SQLException - if a database access error occurs
Since:: 1.2

setNull

public void setNull(int paramIndex,
                    int sqlType,
                    java.lang.String typeName)
             throws java.sql.SQLException

Sets the designated parameter to SQL NULL. This version of the method setNull should be used for user-defined types and REF type parameters. Examples of user-defined types include: STRUCT, DISTINCT, JAVA_OBJECT, and named array types.

Note: To be portable, applications must give the SQL type code and the fully-qualified SQL type name when specifying a NULL user-defined or REF parameter. In the case of a user-defined type the name is the type name of the parameter itself. For a REF parameter, the name is the type name of the referenced type. If a JDBC driver does not need the type code or type name information, it may ignore it. Although it is intended for user-defined and Ref parameters, this method may be used to set a null parameter of any JDBC type. If the parameter does not have a user-defined or REF type, the given typeName is ignored.

Specified by:: setNull in interface java.sql.PreparedStatement

Parameters:: paramIndex - the first parameter is 1, the second is 2, ...; sqlType - a value from java.sql.Types; typeName - the fully-qualified name of an SQL user-defined type; ignored if the parameter is not a user-defined type or REF
Throws:: java.sql.SQLException - if a database access error occurs
Since:: 1.2

setURL

public void setURL(int parameterIndex,
                   java.net.URL x)
            throws java.sql.SQLException

Sets the designated parameter to the given java.net.URL value. The driver converts this to an SQL DATALINK value when it sends it to the database.

Specified by:: setURL in interface java.sql.PreparedStatement

Parameters:: parameterIndex - the first parameter is 1, the second is 2, ...; x - the java.net.URL object to be set
Throws:: java.sql.SQLException - if a database access error occurs
Since:: 1.4

getParameterMetaData

public java.sql.ParameterMetaData getParameterMetaData()
                                                throws java.sql.SQLException

Retrieves the number, types and properties of this PreparedStatement object's parameters.

Specified by:: getParameterMetaData in interface java.sql.PreparedStatement

Returns:: a ParameterMetaData object that contains information about the number, types and properties of this PreparedStatement object's parameters
Throws:: java.sql.SQLException - if a database access error occurs
Since:: 1.4
See Also:: ParameterMetaData

getPreparedStatement

public java.sql.PreparedStatement getPreparedStatement()
                                                throws java.sql.SQLException

Throws:: java.sql.SQLException
