Async StoredProc/TQuery call with Sybase ?

Async StoredProc/TQuery call with Sybase ?

Post by Lou Castald » Tue, 16 Jan 1996 04:00:00

Does anyone know how to execute a Stored Procedure (or a TQuery)
Asynchronously with Sybase?  In other words can Delphi send out the
request to execute a Stored Proc and return immediately so that the user
can go on doing other things until the Proc is finished doing its thing
(searching for example) or have the user cancel it if desired.  Any help
on this would be very much appreciated.  Thank you.

1. Help: Sybase Async Calls under MS-Windows


I trying to set up a ct-library connection in Async  mode
under MS-Windows. According to documentation, My completion callback
routine should only be called when I call ct_poll routine. However,
I have observed that Completion callback is called from within the
routines which are supposed to return CS_PENDING code. For example,
upon calling ct_send, completion callback is invoked even before
ct_send returns. This ultimately results in stack overflow !!!!

I would appreciate any help, if anybody has tried this before and
knows how to resolve the problem. Thanks in advance.
