[Pypgsql-users] Determining size of result set?

[Lars Kellogg-S. <la...@la...>]

Hello all,

I've just started using pyPgSQL, and I've run into a frustrating problem 
-- how do I determine the size of a result set *before* calling one of 
the fetchxxx() functions?

The rowcount attribute doesn't appear to be terribly useful.  As far as 
I can tell, it simply tells me the number of rows returned by the 
previous fetchxxx() call -- a value which I can also get just by calling 
len() on the return from fetchxxx().  Before a fetch call, rowcount 
always contains -1.

Is there any other way of getting at this information?

Thanks,

   -- Lars
