Hello.

Is it possible open cursor with only one time execution on DB server? I mean if is possible exclude first, describe only, call of server. Describe is offered by server implicitly with execution of select, no explicit call is necessary but ODAC used it for preparing fields...

I found

FAutoInitFields: boolean; // initialization fields by InternalInitField
FDeferredInitFields: boolean; // initialization field on Open, if False then on Prepare

but I don't konw if is possible change it without damage of functionality.

Can you help me, please?

ODAC: 3.90
Oracle: 8-10
Delphi: 4

Thank you very much.

This problem is fixed in new versions of ODAC.

Yes, from version 4.00 but we use Delphi 4 and ODAC 4.00 and higher isn't compatible with Delphi 4...

In ODAC 3.90 it is not possible to open query without describe-only execution. You cannot change values of FAutoInitFields and FDeferredInitFields without damaging of ODAC functionality.
