Topic: Which character is sent when clearing a field?
I am playing around with your fantastic application and I would like to understand which character the application send to the database to clear a field?
If I edit a field which was 'null' usind the function "Edit" in a formand save it, everything is Ok. Example: set Firstname to 'Test1'
If I delete this new information then Save (delete Firstname 'Test1'), I cannot retrieve this row using the following sql Query:
select * from <table> where <column> is null or <column> =' '
Which Query should I use?
