IF this is what you are doing (Nancy's question) then you really might wat to reconsider. When a view is opened, it opens copies of the tables it is based on (a view is just like an SQL SELECT, SQL SELECT do this too). But if a copy of the base table is already open in the current work area, the view just uses that copy when it updates. So if the base table is BUFFERED, after you update the view, you have really only updated the buffered table in the same work area. To get the changes back to the real table on disk, you have TABLEUPDATE the table. This is called the double buffering dilemma. Here's the problem:

USE myTable
CURSORSETPROP('buffering','mytable', 3) && set buffering to optimisteic row

USE MyView IN 0 && my is based on MyTable
CURSORSETPROP('buffering','myview', 3) && set buffering to optimisteic row


?GETFLDSTATE(-1,"MyView") && Returns "111"; "clean" buffer
?GETFLDSTATE(-1,"MyTable") && Returns "111"

REPLACE myView.Field1 WITH "Howdy, I'm from Texas"

?GETFLDSTATE(-1,"MyView") && Returns "211"; first field has been modified, "dirty" buffer
?GETFLDSTATE(-1,"MyTable") && Returns "111"

TABLEUPDATE(.T.,.T.,'MyView')

?GETFLDSTATE(-1,"MyView") && Returns "111"; now the view is clean
?GETFLDSTATE(-1,"MyTable") && Returns "211" but tha table is dirty

* And finally, to write changes to the base table you must
TABLEUPDATE(.T.,.T.,'MyTable')

?GETFLDSTATE(-1,"MyView") && Returns "111";
?GETFLDSTATE(-1,"MyTable") && Returns "111"
