Hello,
We haven't found yet any salvation to the following problem. Would
anybody have an idea for avoiding that error so that we could use Maxdb
with server side cursors (through ODBC) ?

Hi list,
I need to display a grid with a large amount of datas. I know I
shouldn't but I must do it anyway :-( To prevent network overload and
large form opening times I decided to test server side cursors. The
test project is quite simple : a dbgrid with a server side cursor
recordset. Using delphi and ADO I must set the recordset as beeing a
readonly keyset. The datas are retrieved as they should and about as
fast as they should (a little bit slower than when using SQL Studio
anyway. Does anybody know why ?). My problem happens when I scroll the
datas too fast. When scroll using the DBGrid the app hangs. When I do
it using code (simple loop through the datas) the app crashes sending
a "Access violation to address... in MSDATL3.dll" error message
depending on how large the cache is set. I thought the problem came
from MDAC but when moving my test application to a PostgreSQL database
it works fine. So I think the problem comes from MaxDB's ODBC driver.
Does anybody knows about that ?
Kind Regards
Xavier
