Hello Svein!

Thank you for answering my post. I was really confused with case I show
you. I haven't any triggers, checks or etc. for this table. I show you
all DDL for it.

I tried to execute my insert statement with InterBase Data Acces
Components for Borland C++Builder 6 (standard components), IBExpert 2
Trial and isql. Everyone gives me the same error message.

I made a backup and restore my DB in another place. An attempt to insert
into "brand new" DB was successful. The source DB with no change.

Finally I've restarted Firebird (v1 on win2000, local machine). And...
it helps!

Now I'm really confused... I hope it wont repeat when I sell my product
to a customer...


With thanks and greetings
