Select..... NOT IN
Hi,
I have a combination of 3 columns are primary key on a table., Say Table A, column a,b and c as PK
I need to select the data from Table A, by excluding the PK records which are already present in B.
Since i have composite PK, i have problem in selecting.
select * from A where PK not in (select PK from B)
can somebody help me ?
