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!

Query of 2 tables with "intersection" table that uses "lookup"

Asked by fvitus in Access Architecture/Design, SQL Query Syntax

Tags: , , ,

Objective: Store and retrieve members attendance to meetings.
Tables
Members
   ID
   Firstname
   Lastname
Meetings
   ID
   MeetingNumber
Attendance
   ID
   MembersID [lookup into "Members" for easy selection and storage of attendance]
   MeetingsID [lookup into "Meetings" for easy selection and storage of attendance]

Relationships
ID in Members to MembersID in Attendance [one to many // join type: inner]
ID in Meetings to MeetingsID in Attendance [one to many // join type: inner]

Creating new records in "Attendance" works fine due to the convenience of the lookup display control - All good so far.

Now to the query that will give me the list of who attended what meeting (later I need to input the meeting I want to see - but for now first step is to get the full list to work...)

Query (it got generated by the query designer in Access 2007):
SELECT Members.FirstName, Members.SurName, Meetings.MeetingNumber
FROM Meetings INNER JOIN (Members INNER JOIN Attendance ON Members.ID = Attendance.MembersID) ON Meetings.ID = Attendance.MeetingsID;

This WORKS - but only when:
The Attendance fields MemberID and MeetingsID are NOT lookups (in "Display Control")

The moment I make the "lookup" the query stops working... However I'd like it to still work in this case - Help?!

cheers...
