Question : combining sql
|
|
is there a way to combine these 3 sql into one sql statement:
SELECT tbl_FD.FstMfgNum FROM tbl_FD GROUP BY tbl_FD.FstMfgNum ORDER BY tbl_FD.FstMfgNum;
SELECT [Tbl_FD Old].FstMfgNum FROM [Tbl_FD Old] GROUP BY [Tbl_FD Old].FstMfgNum ORDER BY [Tbl_FD Old].FstMfgNum;
SELECT Query1.FstMfgNum, Query2.FstMfgNum FROM Query1 LEFT JOIN Query2 ON Query1.FstMfgNum = Query2.FstMfgNum WHERE (((Query2.FstMfgNum) Is Null));

So your goal is . . . what? To get a list of FstMfgNum's from tbl_FD that aren't in Tbl_FD Old? Try this:
SELECT Distinct tbl_FD.FstMfgNum FROM tbl_FD INNER JOIN [Tbl_FD Old] ON tbl_FD.FstMfgNum = [Tbl_FD Old].FstMfgNum WHERE [Tbl_FD Old].FstMfgNum Is Null;
The Distinct will automatically give only one of each and will also sort for you.
Hope that helps . . .
