nextval is a function found in postgres databases and is used to seed the value of a serial(auto increment) that is normally used as a key.
other uses are select currval(serial) to get the current value and select setval(serial,value) to set the vlaue on the fly. much more info can be found in the postgresql docs at http://www.postgresql.org/idocs/ Steve "Ric Manalac" <[EMAIL PROTECTED]> wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > hello. > i've seen DEFAULT NEXTVAL(serial) being used > in some examples but i have not seen an explanation > of what it exactly does. can anyone please explain > what it is and how it can be used? > i have some idea but i want to make sure by asking > other people. thanks! > > ric > > -- > > ================================================================== > Note: The information contained in this message may be privileged > and confidential and protected from disclosure.
