MSSQL Select From Union
If you want to select something from union join on MSSQL using this:
SELECT id FROM
(
(SELECT id FROM t1)
UNION
(SELECT id FROM t2)
)
Problem is that this construct does not work because of Incorrect syntax near ‘)’ error. Solution is simple:
SELECT id FROM
(
(SELECT id FROM t1)
UNION
(SELECT id FROM t2)
) AS T
