PM33170: RENAME OF COLUMN FAILS SQLCODEN750 AS TRIGGER 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 TRIGGER defined. The ALTER TABLE xxx RENAME
  COLUMN aaa fails with a SQLCODE -750 as the DROP TRIGGER
  statement is out of sequence and occurs after the RENAME
  statement rather than before it.
  

Local fix

• Move the DROP TRIGGER statement such that it occurs before the
  ALTER TABLE RENAME COLUMN statement.
