Thanks everybody- I'm watching with a lot of interest. I was worried that I was asking something stupid with an obvious answer... ries van Twisk wrote: > May be this function can help : > > http://www.postgresql.org/docs/8.3/static/functions-srf.html Thanks, that's already turning out to be useful for something else I was working on today: select percent, to_char(nedcar_tonnes_001(percent), '99990.99') AS nedcar from generate_series(0,110,10) as percent; The one thing I'd say about generate_series() is that the description suggests that one has to put an explicit count() as the second parameter if using it to number rows, i.e. it doesn't have an "as many as necessary" option. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues]
