By specifying a valid member name, the explanation of SQL statements can be limited to certain member(s); an asterisk (*) can be used for range specification:

  • If you specify a unique member name, all SQL statements contained in this member are explained;

  • If you specify a value followed by an asterisk, all SQL statements contained in all members with names beginning with the specified value are explained;

  • If you specify an asterisk only (or leave the field blank), all SQL statements of all existing SQL members are explained.

A query number must be specified, so that with each issued EXPLAIN command, the newly created explanation is added to the appropriate query number. The default query number is 1.

To issue the EXPLAIN command, enter function code X and specify a valid member name and query number; all SQL statements contained in the specified member(s) are explained.

If LISTSQLB is executed online, the following screen informs you about the processing status of the command and if any errors have occurred.
