>Another option is to use SQLEXEC() to create a cursor, then you can modify the following code to make that cursor updatable. For ALL my tables, I use a surrogate numeric PK that is always named KeyID and I do not make that field updatable because it is automatically generated by the server. Then you can use APPEND, DELETE, REPLACE, TABLEUPDATE(), TABLEREVERT(), etc.
