Question

I have a Query:

SELECT Column1 FROM Table WHERE Column2 IN (‘val1,’val2′,’val3′,….’valn’);

Now I want those values which didn’t return any rows. Means those values which I have passed in IN functions but they are not present in my tables.

Sorry if I failed to make it clear 🙂

Answer 1

SELECT x.f FROM
(SELECT 'val1' as f
UNION ALL
SELECT 'val2'
UNION ALL
SELECT 'val3') x
LEFT JOIN Table t ON x.f = t.Column2
WHERE t.Column2 IS NULL
