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.

Can't get return value out of a stored procedure (SQL 2000)

Asked by raterus in MS SQL Server

I have an exe that runs based on parameters and returns a value by updating a table. Crude, but it should work.

I'm wrapping this exe functionality into a stored procedure, for which I'll call with paramters, and get a return value from it.

I'm having trouble getting this value out of the stored procedure. It's there, because if I uncomment line 22 below, I'll see it when executing the lower SQL.

Can someone tell me why I can't get this value out of the procedure using the method I'm using. I tried also rewriting to use output parameters, but that did not work either.
