NetDatabaseMetaData40

public NetDatabaseMetaData40(NetAgent netAgent,
                             NetConnection netConnection)

Method Detail

getJDBCMajorVersion

public int getJDBCMajorVersion()
                        throws java.sql.SQLException

Retrieves the major JDBC version number for this driver.

Specified by:

getJDBCMajorVersion in interface java.sql.DatabaseMetaData

Overrides:

getJDBCMajorVersion in class DatabaseMetaData

Returns:

JDBC version major number

Throws:

java.sql.SQLException - if the connection is closed

getJDBCMinorVersion

public int getJDBCMinorVersion()
                        throws java.sql.SQLException

Retrieves the minor JDBC version number for this driver.

Specified by:

getJDBCMinorVersion in interface java.sql.DatabaseMetaData

Overrides:

getJDBCMinorVersion in class DatabaseMetaData

Returns:

JDBC version minor number

Throws:

java.sql.SQLException - if the connection is closed

getRowIdLifetime

public java.sql.RowIdLifetime getRowIdLifetime()
                                        throws java.sql.SQLException

Indicates whether or not this data source supports the SQL ROWID type. Since Derby does not support the ROWID type, return ROWID_UNSUPPORTED.

Returns:

ROWID_UNSUPPORTED

Throws:

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

isWrapperFor

public boolean isWrapperFor(java.lang.Class<?> interfaces)
                     throws java.sql.SQLException

Returns false unless interfaces is implemented

Parameters:

interfaces - a Class defining an interface.

Returns:

true if this implements the interface or directly or indirectly wraps an object that does.

Throws:

java.sql.SQLException - if an error occurs while determining whether this is a wrapper for an object with the given interface.

unwrap

public <T> T unwrap(java.lang.Class<T> interfaces)
         throws java.sql.SQLException

Returns this if this class implements the interface

Parameters:

interfaces - a Class defining an interface

Returns:

an object that implements the interface

Throws:

java.sql.SQLExption - if no object if found that implements the interface

java.sql.SQLException
