Hi,
There is a column in my table with not null constraint. Default value is
set to 0 for that column. In my query, column value is set to null. When i
try to execute that query in pgsql, it is getting failed due to constraint
violation. Any idea? This is working in oracle.
Thank You!

Hi,

Thanks!

In order to get the default value to kick in in an insert statement (which
I assume you're trying to do), you can either omit that column name from
the insert list or set that column value to DEFAULT (no quotes)
