Interface ExtractedDatabaseMetaData

public interface ExtractedDatabaseMetaData

Information extracted from DatabaseMetaData regarding what the JDBC driver reports as being supported or not. Obviously DatabaseMetaData reports many things, these are a few in which we have particular interest.

String	getConnectionCatalogName() Retrieve the name of the catalog in effect when we connected to the database.
String	getConnectionSchemaName() Retrieve the name of the schema in effect when we connected to the database.
Set<String>	getExtraKeywords() Get the list of extra keywords (beyond standard SQL92 keywords) reported by the driver.
JdbcEnvironment	getJdbcEnvironment() Obtain the JDBC Environment from which this metadata came.
