Hi,

I have a table test. It has a primary key column ID and a unique key column ID2. I want to drop the unique key from column ID2.

Alter table test drop unique (ID2); is not working. How do I achieve this.

Thanks.

Hi,
U have to use following command,

alter table [table_name] drop constraint [constraint_name]

If u dont have the constraint_name then use following command retrive it.

select * from user_constraints where table_name = 'TABLE_NAME'

Hope this helps.

Thanks,
Mahesh
