>Try it. [snipped example] Ah. Basically, you set up the rule to assign every column, and if the update doesn't redefine some columns, then it still works. I didn't understand that you could get the rule to work generically like this.
I'll presume that the rule will need amending if the table column definition later changes. (E.g. if I add 'stalk_length' to my apples and pears tables)... Thanks very much for your help.
