then it (IBO) will know to "select ID from table where etc" instead of all
your required fields when it only wants a list of IDs to fill it's buffers.
There are many other places it parses your SQL to achieve some prety damn
nive stuff for you and to increase performance racially.

you are being express about your need to have all unfiltered records at the
client - thus your need to use the onfilter event. If it were a query, the
onfilter event would be useless. Perhaps there is a setting in the component
to use queries?
