Specifies the cursor handle for the dataset.
Syntax:
type HDBICur: Longint;
property Handle: HDBICur;
Description:
Use Handle only to bypass TMySQLTable methods and call directly into the MySQL.
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.
