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!

Can you use the result of a SQL query inside another SQL query in the same statement?

Asked by GuruGary in MySQL Server, Bourne-Again Shell (bash)

Tags: MySQL

I am writing a bash script to backup some information. I am currently a MySQL novice, but I figured out that I can find location(s) of this information by doing 2 SQL queries like:
"SELECT id FROM domains where name='$SITE' limit 1"
I then take the result of that ($DOMID) and use it in the other query like:
"SELECT name FROM data_bases where dom_id=$DOMID"

My question is can I combine the 2 queries to basically do something like:
"SELECT name FROM data_bases where dom_id=(SELECT id FROM domains where name='$SITE' limit 1)"

I am calling these from a bash script like:
mysql -usuer -ppassword -Ddatabase -e "SELECT ..."
So a related question would be, is there also a way to suppress the column labels and/or ASCII boxes around the output, so my parsing of the output would be easier?
