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 EricHoma in MySQL Server, ColdFusion Application Server
I have two tables, one with about 5000 records, the second with about 3000 records. MySql is the database server for a Cold Fusion server based web site. I have a search form where the user enters a search string. I need to first search the first table and return results using the following query: SELECT PartNumber, Description FROM PartList WHERE PartNumber LIKE %'searchstring'% OR Description LIKE %'searchstring'%. Let's say that I get about 17 records back. Then I need to search the 2nd table for similar records but I want to exclude part numbers that were found in the first query. I tried this: SELECT PartNumber, Description from OtherPartList WHERE (PartNumber LIKE %'searchstring'% OR Description LIKE %'searchstring'%) AND PartNumber NOT IN (SELECT PartNumber, Description FROM PartList WHERE PartNumber LIKE %'searchstring'% OR Description LIKE %'searchstring'%). The 2nd search query seems to chug along forever and consume all sorts of server resources. Am I on the wrong track here? Doing it wrong, phase of the moon..... Please Help!
