There are more rows in that table. It's one that we use for storing sequential numbers we use... like invoice numbers, membership numbers etcetc
So we have to lock row when using it, so noone else uses the same number when we add a new member or create a new invoice... But good advice tho, and I would have used lock on it if not for the fact that we have to use row locking on it... /Stefan > -----Ursprungligt meddelande----- > Fr�n: Rachel Carmichael [mailto:[EMAIL PROTECTED]] > Skickat: den 25 januari 2002 15:00 > Till: Multiple recipients of list ORACLE-L > �mne: Re: Hmmmmm > > > is there only one row in that table? if so, you can lock the table > itself. > > try it without the nowait... > > > > --- Stefan Jakobsson <[EMAIL PROTECTED]> wrote: > > Having a small problem I need some help with... > > > > The problem is trying to lock a row on a parameter table for an > > application. > > > > The thing we need to do is following: > > > > Read the value in one row.
