1) You can open and close or you can use view's connection handle.
2)I don't see a correlation between like and >=. Maybe you meant = and like. It wouldn't matter much IMHO. myField like 'A%' is partially optimizable and myField = 'A' is fully optimizable(ANSI is off - having same result). I prefer = too whenever I can.
