Issue/Introduction

I only want to drop a column of a table with RC/Update alteration or a RC/Migrator strategy.

 

However, a DROP TABLE is generated instead of ALTER TABLE ..  DROP COLUMN ...

Environment

Release:
Component: RCM

Resolution

Please make sure there are no DB2 restrictions for dropping the column, e.g. if the containing table space is not a universal table space.

 

See a complete list here:
