question about default value and timestamp

От

Hi list,

i have a table with a column where the default value is current_timestamp, but somehow all the tuples (around
8.000.000)have the same timestamp, which is, honestly speaking, not what i intended to do. So is the current_timestamp
functiononly executed when the insert statement starts? I mean of course i can change it and insert the
current_timestampexplicitly in every tuple, i just would like to know why it doesn't work the way i wanted it to
work...

Thanks!
Chris

No, but when the _Transaction_ starts. You can use timeofday() instead.
