PM31726: RENAME OF COLUMN FAILS SQLCODEN750 AS CONSTRAINT NOT DROPPED BEFORE RENAME.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The DB2 Object Comparison Tool for z/OS generated DDL in the
  wrong sequence when attempting to implement a RENAME of a column
  on a table with a CONSTRAINT defined. The ALTER TABLE xxx RENAME
  COLUMN aaa fails with a SQLCODE -750 as the DROP CONSTRAINT
  statement is out of sequence and occurs after the RENAME
  statement rather than before it.

  ****************************************************************
  * PROBLEM DESCRIPTION: The DB2 Object Comparison Tool renamed  *
  *                      the table column before dropping the    *
  *                      constraint.  The change failed with a   *
