a little basic question here
I usually use something like this in stored function
to get the last value of a serial type column
select last_value into ret from id_sequence
return ret
What i'm asking is,
if many people run the same stored function at the same time
will they get the last_value they should really get
or is there another way to code that can ensure they really get the right value
Thank you
