.BR Update
changes the values of the attributes specified in
.IR target_list
changes the values of the attributes specified
for all instances which satisfy the qualification,
.IR qual .
Only the attributes to be modified need appear in
.IR target_list .
Only the attributes to be modified need appear as atributes.

Array references use the same syntax found in
.IR select(l).
That is, either single array elements, a range of array elements or
the entire array may be replaced with a single query.
.IR from-list
is a non-standard extension to allow columns from
other tables to appear in the target_list.
.PP
You must have write access to the class in order to modify it, as well
as read access to any class whose values are mentioned in the target list
