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 syntax like "UNION INTERSECT" in SQL (Oracle specific)

Asked by vsuripeddi in Oracle Database

Tags: , , , ,

Experts,

I am looking to select all rows in table A but not in Table B.

so currently i can get to select this result set by doing the following query

(SELECT * from table A
MINUS
SELECT * from table B)
UNION ALL
(SELECT * from table A
INTERSECT
SELECT * from table B)



I am wondering if there is a better way/ syntax to do this in Oracle ,
say using something like UNION and INTERSECT together
to achieve the above result set

(Basically I want to get all the rows in table A
but do not want to lose any rows in table A  
--- when we do the MINUS we will lose the common rows)


Would like to know some tips on set operations to do nifty things

Thanks a bunch
