Can this be done in the framework of plpgsql? I know I can do it in the front end (java) but it would be nice to aviod having to grab the rowcount first. I haven't seen a random function in the documentation. I could install another language but boy am I lazy :) --- Mark Lane <mlane@mynewthing.com> wrote: > On Tuesday 06 February 2001 13:11, you wrote: > > Any suggestions on how to select a random record > from > > any given table? > > > > Culley > > > Set the range of the table index to a random number > generator. > > if the index ranges from 100 to 10000 then you would > multiply you random > number by 9900 and then 100 to generate a random > index number.
