Not Allowing Null And Duplicates

[JonathonBevan1342106235]

Hi

I have a table called projects.

It seems to me the best validation when a user enters data is that the database 1. will not accept null in the field project_name and 2 will not allow duplicate project names in the field project_name (ignoring case).

Unfortunately - the "null checkbox" is disabled when I look at my table or sample tables. So I am unable to toggle allow nulls..

Also, I have spent ages looking at the documentation and I cannot find how to not allow duplicates. I really want to apply the rule to the database...

I could do an SQL lookup I suppose but that is more complicated than I imagined. The foundset is a subset of projects so using that cleanly is no good. If I try to do a dataset Servoy tells me there are unupdated foundset records (which is right, I am currently in validation mode and I don't want to save the changes until record is valid). etc..etc..

Any help would be much appreciated

Servoy is 'database agnostic', meaning it can connect to any JDBC enabled database, but this also mean that any specific action on that database should be done on specific client/admin UI.
So, depending on the database you are using, you need an admin client to change the nullable value of a field, and add unique constraints, this is not done in Servoy.
For PostgreSQL for example, you can use pgAmin III which is a very good DB client which will allow you to manage and maitain your database. It's free and Open Source and you can download it from here: http://www.pgadmin.org/download/

Thank you very much. I understand that answer. I know Sevory is a front end thing... I just thought it might support basic common SQL components.

Kind Regards
