The SET QEP statement displays a diagrammatic representation of the query execution plan chosen for the query by the optimizer. The SET NOQEP option disables this option.

SET QEP CONCISE displays the QEP in a format that is suitable for parsing by a program.

SET QEP SEGMENTED displays QEP as a series of segments that are easier to read when parsing complex SQL statements.

For a discussion of query execution plans, see the Database Administrator Guide.
