Hi, Hmm, Ok I try to explain: If I write: insert into table_1 values ('f1_value',10); It is error because I try to insert 2 fields in 3-fields table. The reason is that I can make write error. If I write : insert into table_1 (field_1,field_2) values ('f1_value',10); It is no problem because I have specified exact the inserted fields and I have one missing and it is not NOT NULL. The problem is that pg do not report the first error. And as I wrote oracle, MS SQL and mySQL reports correct the error. I think this bug is potencial ground for many errrs by developing. regards, ivan.
