hey all,

quick question:  does anyone know when/what makes query/400 decide it must
read all records for the query before displaying the first page?

I use query a lot for quick one-off reports, mostly for my own analysis,
and in some complicated querys (joins, sorting on fields from different
files, etc) the query reads through all records before displaying the first
page.

sometimes, by omitting just one field from the sort, it won't have to read
the whole thing.

just curious,  TIA.
