DB2 400 drop column

Question

I want to drop a column called id which is an auto incrementing PK.

The SQL:

alter table \"CO88GT\".\"XGLCTL\" drop column id cascade;
         


        

Answer 1

There isn't enough information in your error message to be sure, but dropping a primary key column is generally quite risky and the database correctly makes it difficult.

You likely have a foreign key constraint involving that column.

Don't drop the constraint and delete that column unless you're sure you know what you're doing.
