I have a table
. 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.

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.
It is sorta covered in the
JavaRanch Style Guide
subject: Dropping Unique Key
how to make the column unique?
hibernate : ternary association mapped by a map (like book page 347)
struts2 drop down - unique values
