Hello.

1 - I created a column NOT NUL in a table (ALTER TABLE MYTABLE ADD 
NEW_COLUMN INTEGER NOT NULL). There were already some records in the 
table. FB didn´t raise any warning or exception.
2 - I created a backup file from MYDB.FDB using gbak.  FB didn´t raise 
any warning or exception.
3- I tried to restore the backup file to a new MYDB.FDB and FB raises 
and error: gbak: ERROR:validation error for column NAME, value "*** null 
***"

Let´s accept than the step 3 is coherent.

So, why can I execute step 1 without troubles?

Well, someone can tell me to use -no_validity to restore the database. 
Ok, it works. But, the column that should be NOT NULL will change, 
without warning, and I have to check my tables after restoring DB.

I am using FB 2.5 and I tried using FB 3.0 too.

Is it as I described or there is another way to treat this?

Atenciosamente,
