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!

query to group by one column with comma separated list for values from other column

Asked by dblankman in Oracle 10.x, PL / SQL, Oracle CRM

Tags: oracle, sql

I have a database with two data tables and a third table for linking.
Table 1: Research Sites
SITE_ID        SITE_NAME
1                   ARAVA
2                   ADULAM
3                    Avdat

Table 2: Research topics
TOPIC_ID      TOPIC_NAME
100                 Topic 1
101                  Topic 2

Table 3:  Link table

TOPIC_ID     SITE_ID
100                 1
100                  2
100                 3
101                 2
101                 3

I would like to end up with something like:

TOPIC_NAME     SITE_NAME
Topic 1                 Arava, Adulam,Avdat
Topic 2                  Adulam, Avdat

I know the join syntax but can't remember how to get the comma separated list
