Hi!

You're not correct. Any view and SPT cursor could be made updatable. There are 5 properties of cursor you can set to organize any king of update for any cursor. The query used to make cursor does not matters. Well, you cannot do this from the view designer, but definitely you can do this using CursorSetProp() and DBSetProp() functions.

>>>It's legal to use UNIONs in a view, as long as it's defined with CREATE SQL VIEW and you don't later attempt to modify it with the VFP View Designer.
