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! |

Asked by alex_wareing in SQL Query Syntax, MySQL Server
I'm trying to make a LEFT join using SQL. However the fields I am trying to join are not exactly the same. I have two tables 'geonams' and 'admin1codes' the key in 'admin1codes' is like this 'FR.01' and the 'geoname' table contains two columns that make up this key so there is a 'geoname.country' that is 'FR' and an 'admin1' that is '01'.
My question is how can i combine these two columns to test for a match in the other table, my attempt was:
LEFT JOIN admin1codes ON admin1codes.code = geoname.country + '.' + geoname.admin1
But that didn't work, how do i do this?
