Using a Collection in an 'IN' Clause

Question

Hi,
I would like to create either a nested table or index-by table to aggregate a set of record ids (eg. social security numbers). Then I would like to use the nested table in an IN clause.
Example:
TYPE SSN_TABLE IS TABLE OF EMP.SSN%TYPE;
v_SSNs SSN_TABLE;
--POPULATE v_SSNs PER SOME LOGIC
-- CRAPS OUT HERE
SELECT * FROM EMP WHERE SSN IN (v_SSNs);
While I can create and populate the nested table, I cannot, for the life of me, figure out how to use it in an IN clause.
Any help would be greatly appreciated...

Answer 1

Try
SELECT * FROM EMP WHERE SSN IN (select SSN from v_SSNs);
