ALTER TABLE DROP multiple COLUMNs

If you want do delete multiple columns of a table using "ALTER TABLE tbname DROP COLUMN colname", you currently have to execute many ALTER TABLE statements. The execution time increases exponentially with the number of columns to be deleted. If th...

Improve ALTER TABLE ROTATE PARTITION

Currently ALTER TABLE ROTATE PARTITION only allows the ENDING value to be a constant, minvalue, or maxvalue. I would suggest adding the ability to generate DATES or TIMESTAMPS so that additional programming is not necessary to generate the ALTER s...

Stop package invalidation after ALTER MAXPARTITIONS

These days in an agile world we have to ALTER PBG spaces on-the-fly to raise the MAXPARTITIONS value. Sadly this ALTER, even though it is an immediate ALTER, sets all dependent packages to VALID = 'N' which is, of course, a disaster.

Add support for GRANT ROLE to AUTHID.

In DB2 for z/OS I am allowed to CREATE ROLE, GRANT priviledges to ROLE but I can't GRANT that role to a USERID. Seems something is broke to me. What are ROLES good for if I can't assign a user or group of users to that role.

Implicit Tablespaces for conversion of multi-table tablespaces to UTS PBG

When converting multi-table tablespaces to universal tablespaces with new command ALTER TABLESPACE MOVE TABLE you need to create a new tablespace for each table explicitely before you can use the command. It would be very nice if the ALTER TABLESP...
