Problem summary


    

  • ****************************************************************
* USERS AFFECTED: Users of Db2 Administration Tool for z/OS    *
****************************************************************
* PROBLEM DESCRIPTION: Object Compare generates the incorrect  *
*                      order of DDL statements when importing  *
*                      change statements.                      *
****************************************************************
The following statements are imported into Change Management
as a change. Then this change is analyzed and run.
  ALTER TABLE <TB1> ADD <COLX> GENERATED BY DEFAULT IDENTITY
  CREATE INDEX ON <TB1> ( <COLX> )

When this change is applied to the target Db2 catalog,
statements are in the incorrect reverse order.
  CREATE INDEX ON <TB1> ( <COLX> )
  ALTER TABLE <TB1> ADD <COLX> GENERATED BY DEFAULT IDENTITY

Object Compare should generate ALTER TABLE first and then CREATE
INDEX, because COLX is added to TB1 by the ALTER TABLE statement

Keywords: GENERATED, IDENTITY
