is this a legal IN statment?
Code:
...
ELSIF p_client_id IN(SELECT client_id FROM client) THEN
...


I just need to validate that the p_client_id value is an actual client from the client table.

I have discovered that in Oracle (9i at least) that you cannot use the IN function inline in an IF statement. You could, however, write a boolean function to return a value indicating whether or not your value is in the set.
