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!

Update from multiple tables

Asked by jhdaniel in Oracle Database

Tags: , ,

The question below comes from this site.  It's an accepted answer.  However, this syntax doesn't work for me.  I get an error on the comma (after carts c,) that I'm missing the SET keyword.  1) Is the syntax below incorrect, and 2) if it is incorrect, then how can you update multiple rows using data from other columns, the way it's described below?  

<<
the above update is incorrect :

UPDATE carts SET carts.format_code = prices.format_code
WHERE cart_item_id IN
      (SELECT cart_item_id from prices, carts
       WHERE  blah blah blah.....)

the 'prices' table is unknown to the update statement, and only exists in the sub-select.

However, you can issue the following update commnad in order to get the requested affect :
UPDATE carts c, prices p
SET c.format_code = p.format_code
WHERE c.cart_item_id IN
      (SELECT t.cart_item_id from prices r, carts t
       WHERE  r.<price_table_key> = p.<price_table_key>
      AND    blah blah blah.....)

Hope it answered your question.
