Export by Query

This export method uses DML statements to identify database objects to export. The export‑by‑query operation uses the SHOW QUALIFIED statement; therefore, use only DML statements as input. In other words, do not use Data Definition Language (DDL) statements. For more information about the SHOW statement and restrictions, refer to SQL Data Definition Language B035-1184.
