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!

ODBCParametersCollection data transfers between 2 data sources - By Reference

Asked by TimPeer in .NET, C# Programming Language

Tags: C Sharp, ODBC DataAdapters, ODBCParameterCollection, Data Transfers by reference

I have a C++ application I had written sometime ago wherein I am calling the ODBC API directly, SQLDescribeCol, SQLExecute etc. to copy data between data sources. I am updating the application on C Sharp. The approach I used, allocate buffers on the heap and map the addresses to the ODBC API calls  by reference. The resulting transfers are very very efficient. Data has changed and new requirements seem to indicate a C Sharp rewrite of the application. Managed code will not be as efficient, but it will be very stable without the foibles of unmanaged heap allocation.

The approach that I am coding will implement ODBCParameters and prepared statements for the transfer operations.

Question, for efficiency I would think populating the source adapter's ODBCParameterCollection once for each row and reference the collection by the target data source would seem to be the most efficient way to transfer rows from Source to Target data tables.

Is this possible?

Transaction operations include: Delete from where ... , insert into ... update where ...

Thanks!
