Hi,

In have a Firebird 1.5 database, which somehow does not have NOT NULL ticked for the primary key field of a few tables.

When I restore the database on Firebird 2.5, it just silently drops the primary keys.

I have found and corrected 2, but suspect there may be more, which could cause some nasty headaches further down the line.

Is there any way I can see which primary keys were problematic, and therefore dropped?

I have checked the verbose restore log (no errors or warnings shown, I have tried validating the database using FB2.5 and the old ODS structure, and I have tried checking the Firebird.log.

The only thing left I can think of will be to try write a sql statement to run on the old database, to extract all primary keys that don't have a not null constraint, but that is going to take the rest of the day to get right.

Any better ideas?

Thanks
Maya
