Hi,
No, I am sure that I can get this message from Delphi. Check it on web site www.microolap.com
For example when I try to put a non-unique value in a primary key I get message from database that I get conflict with primary key :-)
of course I use raise ... except ... but everything work perfectly... error handling works correctly :-)
so I am waiting for an answer for my question how check that the rekord is currently edited,
Greetings,
Daniel
