-	 * and the only workaround is to (re)execute the statement or cursor
-	 * in order to go to the first (zero) index of the result set.

-	 * right one.
-	 *
-	 * This is as ridiculous as it sounds and it's the reason why every
-	 * other method that is fetching data tries to use an already "cached"
-	 * result set. Keeping this just in case it becomes needed at
-	 * some point in the future, but it will only work for resetting the
