EXPLAIN SQLSTMT specifications

This section describes the EXPLAIN SQLSTMT specifications.

Usage

Use this specification to investigate a particular SQL statement supplied in its text form.

Usage notes

  • The supplied SQL statement is explained by SQL EXPLAIN using a query number of 999735911. If this number already exists in the PLAN_TABLE of the job submitter, OMEGAMON® for DB2® PE explain deletes the rows before processing the SQL statement. After successful execution of SQL EXPLAIN, the newly created rows in the PLAN_TABLE of the job submitter are used to produce the usual OMEGAMON for DB2 PE Explain report.
