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!

Combine Aggregate and Non-Aggregate Fields in a single statement

Zone: Microsoft Access Database

Tags: aggregate, combine, fields

Thank you for reading my question.

Let's say that I have a list of products in a table entitled tblProductHistory with the following fields:

intProductHistoryID integer autoincrement
intTechnician integer (foreign key to tblTechnicians)
intProductID integer (foreign key to tblProducts)
datRepairFinished datetime

To find the most recent repair date for any given item, I can do:

SELECT intProductID,
MAX(datRepairFinished) AS datLatestRepair
FROM tblProductHistory
GROUP BY intProductID
ORDER BY intProductID;

and that will give me the product id and the latest date it was repaired.

Now, if I wanted to add the technician ID, I would be unable to do so as it is not part of an aggregate function or the GROUP BY clause.

I suspect that the way to approach this is to join two select statements: the one above, and another that includes the intTechnicianID. However, I am not sure how to do this.

Would anyone point me in the right direction?

Thank you,

FtB
