Question

The documentation here states that

developers must call the
EndExecuteNonQuery method to finish
the operation.

I have not been able to find a good reason as to why this is, or what the results of not calling EndExecuteNonQuery are.

Any insight as to what will happen if it is not called? I don’t want to block on it, is there a way for it to be automatically called in an AsyncCallback?

Answer 1

This will do things like:

• update parameter values (out/return)
• check for exceptions (error codes in the TDS stream – constraint violation etc)
• release any objects/data buffered as part of the above etc

So yes: do it
