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