◆ _getColumnNames()

MDB2_Result_oci8::_getColumnNames ( )

Retrieve the names of columns returned by the DBMS in a query result.

Returns
mixed Array variable that holds the names of columns as keys or an MDB2 error on failure. Some DBMS may not return any columns when the result set does not contain any rows. @access private
