Answer 1

IF @someVariable = 0
BEGIN
   SELECT * 
   INTO #TempTable1
   FROM MyTable
   WHERE Category="Something"
   DROP TABLE #TempTable1
 END
ELSE
 BEGIN
   SELECT * 
   INTO #TempTable2
   FROM MyTable
   WHERE Category="SomethingElse"
   DROP TABLE #TempTable2
END

This will work, but depending on what else you may need the code to do, might not be the best solution; but in your example code it solves the problem.

Alternatively:

SELECT * into #TempTable from MyTable where (1=0)

IF @someVariable = 0
   INSERT INTO #TempTable SELECT * FROM MyTable WHERE Category="Something"
ELSE
   INSERT INTO #TempTable SELECT * FROM MyTable WHERE Category="OtherSomething"

DROP TABLE #TempTable
