Before insert row-level triggers are executed after null constraints are checked #483

I created a before insert trigger to populate non-nullable fields (default 
values are not suitable for this case). I'm using both H2 and Oracle. In Oracle 
this approach works as expected - the values are populated and the row 
validates. In H2, the row is rejected before the trigger has an opportunity to 
populate the values. I found this surprising, and spent quite some time tracing 
through H2 code to understand why the trigger was not being fired.

There is a workaround - using a dummy default value - but that should not 
really be necessary.

Can you please create a small self-contained SQL testcase for this, and then I 
can take a look at fixing this.

Thanks.
