Greetings,

I am doing a query that should pull data from 2 related tables.  The relationship is based on both the Job-ID and System-ID being equal.  What I am getting with the below query is 4 results, when I run the query joined only to 1 table at a time I get back 1 result from the MatlUsageData table and 4 from the Production table.  My desired result set would be 5 rows, with the fields from the other table just blank.

Attached is a spreadsheet showing the current results and showing the desired results.  Any help would be appreciated.

Thanks,
John
SELECT     PUB.Job."Job-ID" AS Expr1, PUB.Job."Cust-ID-Bill-to", PUB.Job."Quotation-Amount", PUB.Job."System-ID" AS Expr2, 
                      PUB.MatlUsageData."Cost-Actual", PUB.MatlUsageData."Cost-Estimated", PUB.Production."Job-ID", PUB.Production."Sub-Job-ID", 
                      PUB.Production."System-ID", PUB.Production."Operation-ID", PUB.Production."Dept-ID", PUB.Production."Work-Center-ID", 
                      PUB.Production."Work-Center-Rate"
FROM         { oj { oj PUB.Job LEFT OUTER JOIN
                      PUB.MatlUsageData ON PUB.Job."Job-ID" = PUB.MatlUsageData."Job-ID" AND 
                      PUB.Job."System-ID" = PUB.MatlUsageData."System-ID" } LEFT OUTER JOIN
                      PUB.Production ON PUB.Job."Job-ID" = PUB.Production."Job-ID" AND PUB.Job."System-ID" = PUB.Production."System-ID" }
WHERE     (PUB.Job."Job-ID" = '280892') AND (PUB.Job."System-ID" = '2')

Hi
Usually if they are of equal match, an INNER JOIN should do the match. If the idea here is that you are losing one record from your join and you have tried that, I would then try a RIGHT JOIN and if that does not bring back what you need, you may try approaching it from a UNION standpoint if that is an accepted option in your environment.
