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!

Performance Issue: Return params or dataset?

Asked by solution46 in MS SQL Server

Tags: dataset, issue, nextrecordset, performance, returning

All,

Assuming I am passing a single row of data, is there any performance advantage to using a series of parameters or a single row data-set to return data from SQL Server?

e.g., the SQL "SELECT * FROM MyTable WHERE MyID = 1" would return, say...
MyID   Field2    Field3
1        A           B
Would I be better declaring two extra params (@Field2 output, @Field3 output) or just allowing the sproc to return the dataset?

This is probably more of an ADO question than a SQL Server question but I'm guessing anybody using SQL Server in earnest will probably be OK with ADO too :).

The real world scenario is that I want to return two sets of data from a single sproc: one single-row set representing a single object and one multi-row set representing a list of its children. There is no significant difference in coding complexity (using .NextRecordset or whatever it's called if I use two recordsets) so I was wondering if there is any other reason to choose one way over the other.

Please, I am after a full explanation of why one way would be better, or why there is no difference, so full points for a detailed answer only.

Cheers,

s46.
