Exceptions, MS SQL & ODBC

When I add a record which invalidates referential integrity to a MS SQL database (using ODBC) in code I recieve no exception, however when I enter the same data using a visual component I recieve the exception - how can I get the exception to be generated by my code?

I don't know if I understood the question ... but you may try wrapping your code within a try/except block:

        try
           { ... your code that invalidates referential integrity }
        except
            raise;     { or however you want to handle it }
        end;

The problem is that although an exception should be generated by the code, it is not!

I have found a work-arround which is to use queries, however I would be interested in finding out the reason for this strange behaviour.

Zac,

Set up a Trigger on your table for the Update / Insert / Delete action using SQL Enterprise Manager that examines the data BEFORE it is commited to the table and have the trigger a RAISEERROR statement which WILL be caught by Delphi so that you can handle it in a Try/Except/Finally Block.

Hope this helps.
