After looking into error messages further, I see that the constraint name is
not included in NOT NULL or UNIQUE constraint errors although it is there in
CHECK constraint errors. The table.column that caused the error is in the
messages so it is possible to identify which column caused the error.

Hi all,
I've been implementing foreign keys in some of my older tables, as detailed at:
http://www.sqlite.org/foreignkeys.html
usually like this:
foreign key ChildTable (ChildColumn1, ChildColumn2)
references ParentTable (ParentColumn1, ParentColumn2)
on delete cascade
foreign key ChildTable (ChildColumn1, ChildColumn2)
references ParentTable (ParentColumn1, ParentColumn2)
on delete no action
I have a few questions:
1. What does SQLite do if the action is just left blank? Does it have the
same affect as explicitly writing no action?
