Hi all,
I have several tables with an 'id' column which is a simple 'serial
unique' type. Often when I insert a record the next thing I need is to
add or edit another table elsewhere using the ID of the entry I just
added. Currently what I do is:
SELECT <table>_id FROM <table> ORDER BY <table>_id DESC LIMIT 1;
and assume (safely thus far) that the returned value is the one I
just created. Obviously this is bulky and, should by chance another
column be added in that time between insert and read, I would get the
wrong value.
Is there a way to do an INSERT (in perl, btw) where pgSQL returns the
value just created by the same INSERT? Thanks!
Madison
