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!

MYSQL update of tables

Asked by hbojorquezgeek in MySQL Server

Tags: , ,

I have the following situation in MySQL 5
I have two tables TableChild  and TableVisit.
Users have entered information in TableVisit BUT I need to go back and do a mass update of TableVisit to include information from TableChild that should have been there.

The original table structure was
TableChild.ChildID,
TableChild.FamilyID

TableVisit.VisitID,
TableVisit.ChildID,
TableVisit.VisitorID

I have 300 entries in TableVisit.

What I want to do is
1.add a column  called TableVisit.FamilyID to TableVisit  (I've done that)
 
2. run a SQL command that will take the FamilyIDs from TableChild.FamilyID and update the TableVisit.FamilyID column with the corresponding FamilyID for that  ChildID

  I basically screwed up and didn’t include the FamilyID in the TableVisit table.
