This may be one faq-item but...

I just noticed surprising fact with BDE how it takes 100% CPU for many

TDatabase connection is kind of one at the time connection. If you open
with large result set, it opens quicly and gives you those lines which you

The but section is that if another query is opened for single line with same
TDATABESE connection, the first query is fetched thrue and before that the
query is executed. The only thing what can be seen is that simple query
takes lots of time

if an another TDATEBASE is used for the simple/second query, the first one
does not
do anything unexpected...

I suppose that same thing can occur with other kind of environments

by the way, thanks about your book ./heLen
