The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Comparing SUMs from Different tables.

Asked by mpdillon in MS SQL Server

Tags: imlstrx_sql, tables, different, sql, sum

I would like to compare SUMs from two tables. Addtionally, I need to find the Sum from the OEOrdLin_Sql table when there is not a matching record(Item_No) in the IMLSTrx_SQL table, thus the outer join.  I am not getting the right answers with my approach.
The first table is an Order Line table. It contains Item_No and Qty_To_Ship.
It’s SUM looks like:
SELECT item_no, SUM(qty_to_ship) AS QtyToShip
FROM  OEORDLIN_SQL L
WHERE (item_no = '115-005-071')
GROUP BY item_no

The second table is a Lot Transaction table. It contains Item_No and Trx_Qty.
It’s SUM looks like:
SELECT SUM(trx_qty) AS TrxQty
FROM  IMLSTRX_SQL
WHERE (item_no = '115-005-071') AND (source = 'O') AND (ctl_no = 0)

The SUM for the OEOrdLin_SQL table is 4.
The SUM for the IMLSTrx_SQL table is 4.

Here is my attempt to compare.
SELECT L.item_no, SUM(L.qty_to_ship) AS QtyToShip, SUM(T.trx_qty) AS TrxQty
FROM  OEORDLIN_SQL L LEFT OUTER JOIN
               IMLSTRX_SQL T ON L.item_no = T.item_no
WHERE (T.source = 'O') AND (T.ctl_no = 0) AND (L.item_no = '115-005-071')
GROUP BY L.item_no

My attempt yields QtyToShip = 16 and TrxQty = 20.

What is the right approach?

Thanks,
Pat

Ultimately, I need to only return those records where QtyToShip <> TrxQty so I will need to add a conditional in the Where or Having clause.
