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!

Is there a way to do this very simple thing?

Asked by owenparker in MySQL Server

Tags: , ,

I know many ways to do this sort of thing using sql statements, or Php or even in a spreadsheet export/import method.  But can this simple thing be done with a single sql statement.  This is just one of those simple things I want to know...

I have a database.  It was 'inherited' and the primary key numbers are huge after many iterations done by a previous developer (i presume).  I added a new field and wanted to populate it with new numbers.  In the old db way, I would have said something like replace newfield with row() and would have gotten newid numbers from 1 to whatever the total number of rows was.

The thing is, there does not seem to be a row() or row_number or rowid field or key built in to MySql.  I'm not really wanting to believe this, although I realize that the row number of a record is really rather variable accordcing to the key being currently used, but surely there is a why to do this 'quick and dirty' with a single sql statment isn't there?

I am very curious to know this, mostly, just to know one way or another...

TIA
