David SELECT SQL creates read-only cursors you can workaround it by if you USE AGAIN the cursor you can also use an non-updatable view Arnon > >I have a Grid whose Recordsource is a Cursor produced via a query. One of the fields is a logical field which is displayed using a checkbox. It all displays perfectly, but it won't allow me to edit the checkboxes. It says the field is 'Read Only'. I want to allow changes to the logical field via the checkboxes. Is there a way to do this? While the other columns of the Grid are marked ReadOnly, this column is definitely not.
