Re: [Lazarus] Append or Insert?

If you are inserting or appending into an indexed table, as far as I know it doesn't make any difference. (And ALL sql tables should be indexed). I usually use append. I think on some tables insert attempts to insert a record into the current location, but this doesn't make any sense in sql, and probably isn't possible. Very basically, using sqldb components, you insert a record, post the insert to the query, apply updates on the query, then commit the transaction.

It's easy to gain control after ShowModal returns but the code has to be repeated as many times as ther are forms to process. The form I want to manage control is also the main form of the program. In a Delphi program I send the main form user-defined messages, whenever certain informations have been changed by other code and must be reflected in my main form. I'm used to send messsages as well. Again, it supposes the (almost) same code to be reproduced for every form. DoDi I think I'm going to implement a timer wich will periodically launch the code. I'll just disable it on places where the program must not be interrupted. In my mind I was thinking to use those moments where the operator comes back to the main menu to start another operation which ensures that nothing else important is guing on, like one form event Thanks anyway I think -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
