Method Detail

getDBType

public static String getDBType(String vendorName)

Get Database Vendor Type from vendor name.

Parameters:

vendorName - Input vendor name. Typically this is obtained by querying DatabaseMetaData.

Returns:

Database type that corresponds to vendorName. If vendorName does not match any of predefined vendor names, the database type returned is generated using following logic.

        detectedDbType = vendorName.toUpperCase(Locale.ENGLISH);
        int i = detectedDbType.indexOf('/');
        if (i > -1) {
           detectedDbType = detectedDbType.substring(0, i);
        }
 

If vendorName is null, DEFAULT_DB is returned.

getEnumDBType

public static int getEnumDBType(DatabaseMetaData metaData)
                         throws SQLException

Gets enumerated database type for given metaData

Parameters:

metaData - Input DataBaseMetaData.

Returns:

Enumerated database type as described by getEnumDBType(java.lang.String).

Throws:

SQLException

getEnumDBType

public static int getEnumDBType(String dbType)

Gets enumerated database type for given dbType

Parameters:

dbType - Input database Type. This should have been obtained from a previous call to getDBType(java.lang.String)

Returns:

dbType translated to one of the enumerations above. If dbType does not correspond to one of the predefined types, OTHER is returned

requireUpperCaseSchema

public static boolean requireUpperCaseSchema(DatabaseMetaData dmd)
                                      throws SQLException

Determines whether to use uppercase schema name for a give database.

Parameters:

dmd - The DatabaseMetaData for the database

Returns:

true if upper case schemaname is to be used. False otherwise.

Throws:

SQLException
