2614668 - DB2 trigger is not dropped before column is removed from table - SAP PD


  • Column is removed from a table that has a trigger defined on it.
  • PD generates the ALTER TABLE ... DROP COLUMN statement.
  • Executing this SQL leads to an error:

SQLCODE = 196, ERROR:   COLUMN table-name.column-name CANNOT BE DROPPED. REASON = 12

  • It should have dropped the trigger first, then dropped the column and finally recreated the trigger.
