Hi all, In IRC, "StuckMojo" commented that the following behavior doesn't seem to be ideal: nconway=> create table my_table (col1 int default 5, col2 int default 10); CREATE nconway=> create view my_view (col1, col2) as select * from my_table; CREATE nconway=> create rule insert_rule as on insert to my_view do instead insert into my_table values (new.*); CREATE nconway=> insert into my_table default values; INSERT 112714 1 nconway=> insert into my_view default values; INSERT 0 0 nconway=> select * from my_table;col1 | col2 ------+------ 5 | 10 | (2 rows) In other words, when the insert statement on the view is transformed by the rule, the "default value" columns are replaced by explicit NULL values (which is the default value for the columns of the pseudo-table created by CREATE VIEW). Is this the correct behavior? Cheers, Neil -- Neil Conway <neilconway@rogers.com> PGP Key ID: DB3C29FC
