Обсуждение: last entry

Is it possible to identify the last entry that has been just insterted
into a table?

If you mean the value of the primary key (if a sequence is used) the way to do that is (in the same connection) to
issuea "select currval('sequencename')" which will return the last used value of that sequence within the current
connection.

If you mean the OID, there is a way to do that too, but I don't use them for ID so I don't know.

We have only two things to worry about:  That things will never get
back to normal, and that they already have.
