>If I select records out of a table into an SQL cursor, and use that cursor as the source for a grid, is there an easy way of updating the table data as the cursor data is updated? Or, is there a way to add an extra field to the cursor for saving the record number from the original table so I can go back after any editing is done, and update the data in the original table?

Select the PK of table into the cursor as well, use cursorsetprop if you want it diffcult.
use cursoradapter otherwise ;-)
