Excel - check whether data added to a SQL database

Hi

In VBA I have written code to add data to an Access database.
I have code that checks the highest ID before and after the Insert Statement
and if this has changed returns a successful entry.
With multiple users however, this might cause problems.
Should I maybe also use a select statement to see if that exact info is there?

If you cannot use an alternative like method I showed with SCOPE_IDENTITY(), then you may need to do something like that to be absolutely certain. For example, you may check for MAX(ID) and 100, then execute an insert that fails, but check for MAX(ID) again which returns 101 as another process successfully inserted a new row. As an alternative, you could run a scalar query that tests EXISTS() or COUNT() ... WHERE based on your criteria; however, if the insert failed because there was already a row with your new data then this method may also be flawed.

You may have to use a stored procedure to do inserts where you can return true or false to indicate success or failure.
