Обсуждение: PGS 7.2 : Insert with wrong number of values did not fail
Hi, I've got a question about a difference beetween PGS 7.2 and PGS 7.4 behaviours. With PGS 7.2 : INSERT INTO table (col1, col2) VALUES (val1) doesn't fail With PGS 7.4 : INSERT INTO table (col1, col2) VALUES (val1) failed Is it a known bug ? Thx. Geoffrey KRETZ Four J's Development Tools

Yes, if 7.2 did that it WAS a known bug. Fixed in 7.4. It is illegal to have unmatching numbers of columns in the insert list and the column list. Did 7.2 really do that?

In 7.3, it's already ok. I've answer the question just to be sure that it's a postgresql bug. Geoffrey KRETZ Four J's Development Tools

More a deliberate change in behavior. The old behavior was intentional
but we decided it was too much at variance with the SQL spec. Now you
can only omit columns when you don't specify a column name list.

Note that in the old version, postgresql would have inserted a default value or a NULL if there was no default. With the addition of the DEFAULT keyword, you can get the same basic effect with: insert into table (col1, col2) values (val1,DEFAULT);
