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!

Passing command line parameters to a MySQL script

Asked by paul_tipper in MySQL Server, SQL Query Syntax

Tags: , ,

I want to run a set of MySQL queries in command line/batch mode from a script file, but I also want to be able to pass parameters from the command line and refer to them in the script file, similar to how command line parameters can be referred to in bash/shell scripts as $1, $2, .. etc. So, the MySQL query file will be invoked as follows:

mysql -u userid -p password dbname <deleteoldrows.sql 10

deleteoldrows.sql will contain a query along the following lines:

$1 in the snippet should be substituted with the '10' passed from the command line. I've already tried this, but needless to say, it didn't work (@1 didn't work either).

Can anyone tell me whether passing command line arguments through to MySQL scripts is possible, and if so, how is it done?Start Free Trial
