Referential integrity

Classic Servoy

Could anyone tell me if this:

http://forum.servoy.com/viewtopic.php?t=933

was implemented in Servoy and can I use this facility?

What is the best solution if I want to check for some fields not to be null and let the user receive a message if the field is null? I could use the method given here:

, checking for null values, but is it better than letting the database manage it?

Hi Sabina,

The best way (at the moment) to check for nulls is BEFORE the record is committed - not at the backend. You need to validate the data on the record on the Servoy side. Being able to check it on the other side is on the planning.
