Interface AdditionalDatabaseMetaData

All Superinterfaces:

java.sql.DatabaseMetaData

All Known Implementing Classes:

OracleDatabaseMetaData

public interface AdditionalDatabaseMetaData
extends java.sql.DatabaseMetaData

This interface defines additional Oracle specific methods for DatabaseMetaData. Rightfully it should be called OracleDatabaseMetaData, but that name is already used by the class that implements DatabaseMetaData for the Oracle JDBC drivers. That class implements this interface. Best practice is to use the standard Java interface, java.sql.DatabaseMetaData. If your app requires access to the additional Oracle specific information then cast the result of getDatabaseMetaData to this type, AdditionalDatabaseMetaData. Use of the class OracleDatabaseMetaData is not recommended and will cause ClassCastException if used with some new Oracle JDBC features.

Method Detail

getOracleTypeMetaData

OracleTypeMetaData getOracleTypeMetaData(java.lang.String sqlTypeName)
                                         throws java.sql.SQLException

Return the type metadata for a named type. Use this instead of the various Descriptor classes and methods. Use of the Descriptor classes and methods such as oracle.sql.TypeDescriptor, is not recommended and will cause ClassCastException if used with some new Oracle JDBC features.

Parameters:

sqlTypeName - the name of the type

Returns:

the metadata for the type

Throws:

java.sql.SQLException - if the type does not exist or some other error occurs

Since:

11.2.0.3.0

getLobMaxLength

long getLobMaxLength()
                     throws java.sql.SQLException

The max size of a lob on the server for this connection. Note that the actual size available for a particular lob will depend on the specific storage allocation.

Returns:

Max size of lob.

Throws:

java.sql.SQLException

Since:

11.2.0.3.0
