Hello Dimitry.

I thought I was testing in FB 3.0, but I wasn´t. I am sorry.

I tried FB 3.0 now and it really raises and error at step 1. Then I use DEFAULT clause and it works like I expected.

Thanks for your answer.

1 - I created a column NOT NUL in a table (ALTER TABLE MYTABLE ADD

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?

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

Did you really try FB 3.0? It should raise an error at step 1.
