方法详细资料

getArray

public Object getArray()
                throws SQLException

Returns the value as a Java array. This method always returns an Object[].

指定者:

getArray 在接口中 Array

返回:

the Object array

抛出:

SQLException

getArray

public Object getArray(Map<String,Class<?>> map)
                throws SQLException

Returns the value as a Java array. This method always returns an Object[].

指定者:

getArray 在接口中 Array

参数:

map - is ignored. Only empty or null maps are supported

返回:

the Object array

抛出:

SQLException

getArray

public Object getArray(long index,
                       int count)
                throws SQLException

Returns the value as a Java array. A subset of the array is returned, starting from the index (1 meaning the first element) and up to the given object count. This method always returns an Object[].

指定者:

getArray 在接口中 Array

参数:

index - the start index of the subset (starting with 1)

count - the maximum number of values

返回:

the Object array

抛出:

SQLException

getArray

public Object getArray(long index,
                       int count,
                       Map<String,Class<?>> map)
                throws SQLException

Returns the value as a Java array. A subset of the array is returned, starting from the index (1 meaning the first element) and up to the given object count. This method always returns an Object[].

指定者:

getArray 在接口中 Array

参数:

index - the start index of the subset (starting with 1)

count - the maximum number of values

map - is ignored. Only empty or null maps are supported

返回:

the Object array

抛出:

SQLException

getBaseType

public int getBaseType()
                throws SQLException

Returns the base type of the array. This database does support mixed type arrays and therefore there is no base type.

指定者:

getBaseType 在接口中 Array

返回:

Types.NULL

抛出:

SQLException

getBaseTypeName

public String getBaseTypeName()
                       throws SQLException

Returns the base type name of the array. This database does support mixed type arrays and therefore there is no base type.

指定者:

getBaseTypeName 在接口中 Array

返回:

"NULL"

抛出:

SQLException

getResultSet

public ResultSet getResultSet()
                       throws SQLException

Returns the value as a result set. The first column contains the index (starting with 1) and the second column the value.

指定者:

getResultSet 在接口中 Array

返回:

the result set

抛出:

SQLException

getResultSet

public ResultSet getResultSet(Map<String,Class<?>> map)
                       throws SQLException

Returns the value as a result set. The first column contains the index (starting with 1) and the second column the value.

指定者:

getResultSet 在接口中 Array

参数:

map - is ignored. Only empty or null maps are supported

返回:

the result set

抛出:

SQLException

getResultSet

public ResultSet getResultSet(long index,
                              int count)
                       throws SQLException

Returns the value as a result set. The first column contains the index (starting with 1) and the second column the value. A subset of the array is returned, starting from the index (1 meaning the first element) and up to the given object count.

指定者:

getResultSet 在接口中 Array

参数:

index - the start index of the subset (starting with 1)

count - the maximum number of values

返回:

the result set

抛出:

SQLException

getResultSet

public ResultSet getResultSet(long index,
                              int count,
                              Map<String,Class<?>> map)
                       throws SQLException

Returns the value as a result set. The first column contains the index (starting with 1) and the second column the value. A subset of the array is returned, starting from the index (1 meaning the first element) and up to the given object count.

指定者:

返回:

the result set

抛出:

SQLException

free

public void free()

Release all resources of this object.
