Specifies the cursor handle for the dataset.
Syntax:
type HDBICur: Longint;
property Handle: HDBICur;
Description:
Use Handle only to bypass TPSQLTable methods and call
directly into the PostgreSQL. Many function calls require a cursor handle parameter. Handle is
assigned an initial value when a dataset is opened. If used with a call that changes the current record
position, call Resync immediately after returning
from the call.
