| metaPrimaryKeys($table,$owner=false) X-Ref |
| Return a list of Primary Keys for a specified table We don't use db2_statistics as the function does not seem to play well with mixed case table names param: string $table param: bool $primary (optional) only return primary keys param: bool $owner (optional) not used in this driver return: string[] Array of indexes |
