Hi,

I use ibodatabase+iboquery(catchupdate,requrestlive).

when I want to delete all record in iboquery,
my code like follow:

while not iboquery.isempty do
iboquery.delete;
iboquery.applyupdate;
iboquery.close;
iboquery.open;


after the iboquery open, some time I will
find there is still 1 record in iboqery.
so I change change the code as:


while not iboquery.isempty do
iboquery.delete;
iboquery.applyupdate;
iboquery.close;
iboquery.open;
while not iboquery.isempty do
iboquery.delete;
iboquery.applyupdate;
iboquery.close;
iboquery.open;


after twice apply the delete action,
the iboquery finally empty.

but why I need twice delete action?

Please Help.
