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!

Perl-sql

Asked by akiles99 in Perl Programming Language

I need  a Perl script that will pass a variable to a series of templates and create MySQL Stored Procedures from the templates.

Inputs: a variable table name and location of the templates will be given as a command line arguments to the script.

Ex:
> script.pl table_name /path/to/templates

Every file with specific extension /path/to/templates will be parsed as a template. One MySQL SP will be created from each template each time the script is calledStart Free Trial

Sample template: 
 
CREATE FUNCTION `proc_$variable`() RETURNS int(11) 
BEGIN 
DECLARE raw_info CURSOR FOR SELECT email FROM table_$variable; 
DECLARE CONTINUE HANDLER FOR SQLSTATE '02000' BEGIN END; 
OPEN raw_info; 
main: LOOP 
<do something> 
END LOOP main; 
CLOSE raw_info; 
RETURN SELECT count(*) FROM table_$variable; 
END 
 
Assuming sample template in /opt/templates and script called like this: 
 
> script.pl 55 /opt/templates 
 
Script will read templates and create the following SP in the MySQL DB: 
 
CREATE FUNCTION `proc_55`() RETURNS int(11) 
BEGIN 
DECLARE raw_info CURSOR FOR SELECT email FROM table_55; 
DECLARE CONTINUE HANDLER FOR SQLSTATE '02000' BEGIN END; 
OPEN raw_info; 
main: LOOP 
<do something> 
END LOOP main; 
CLOSE raw_info; 
RETURN SELECT count(*) FROM table_55; 
END
