Hi,

Why does this query give me a syntax error in MS SQL Server?

select dv_id, dp_id from em where dv_id, dp_id not in (select dv_id, dp_id from dp)

I'm just trying to check for invalid data for a foreign key referencing a two-part primary key.

What is the correct syntax for this? Thanks in advance.

this will do:
select dv_id, dp_id from em where not exists (select null from dp where dp.dv_id = em.dv_id and dp.dp_id = em.dp_id) 

Open in new window

Your subquery (select dv_id, dp_id from dp) must not return multiple fields if you want to use the NOT in clause
