Hello!
You can do it in Oracle, but how to do that in MS SQL.
I don't whish to write

select * from a where field1fromA=1 and field2fromA=2

because i want to generate (1,1) from a subselect...

Thanks
Bjoern

Hi Bjoern,

You can change the IN to an EXISTS:

Illegal in SQL Server:

SELECT something
FROM a
WHERE (field1, field2) IN
(SELECT col1, col2
FROM othertable
WHERE whatever = something)

Equivalent, legal in SQL Server:

SELECT something
FROM a
WHERE EXISTS
(SELECT *
FROM othertable
WHERE whatever = something
AND col1 = a.field1
AND col2 = a.field2)


Best, Hugo
