getMetaData()

Syntax:

ResultSetMetaData getMetaData()
                              throws SQLException

Description:

Retrieves a ResultSetMetaData object that contains information about the columns of the ResultSet object that will be returned when this PreparedStatement object is executed.

Because a PreparedStatement object is precompiled, it is possible to know about the ResultSet object that it will return without having to execute it. Consequently, it is possible to invoke the method getMetaData on a PreparedStatement object rather than waiting to execute it and then invoking the ResultSet.getMetaData method on the ResultSet object that is returned.

Returns:

the description of a ResultSet object's columns or null if the driver cannot return a ResultSetMetaData object

Throws:

SQLException - if a database access error occurs or the prepared statement has been closed
