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 statement using inner join

Asked by servantis in Oracle Database

Tags: , , , ,

I have two tables ALPHA and BETA. I need to update the BETAID to the ALPHAID. The BETAID is currently set to the ALPHADESC so I am joining on this column.

The following update statement works fine in SQL Server:

UPDATE BETA
SET BETAID= A.ALPHAID
FROM TABLE BETA
INNER JOIN ALPHA A
ON BETAID= A.ALPHADESC

So using the lookup table Alpha:-

ALPHAID        ALPHADESC
1                   First
2                   Second
3                   Third

This changes the Beta table from:-

BETAID
First
Second
Third

To:-

BETAID
1
2
3

So, the query is simply using a lookup table to replace a description with its corresponding ID, one row at a time. I now need to replicate this query in Oracle. Using the following:-

UPDATE BETA
SET BETAID = (SELECT A.ALPHAID FROM ALPHA A, BETA B
WHERE B.BETAID = A.ALPHADESC);

Results in 'single-row subquery returns more than one row', as expected. How would I rewrite this query for oracle?
