be performed if an Oracle Rdb error occurs.

all the context variables on the left side of the assignment in a
MODIFY statement must refer to the same relation.
3 – record-descr
A valid data dictionary record descriptor matching all the fields
of the relation.
4 – field-name
The name of the field to be modified.
5 – value-expr
an Oracle Rdb value expression that specifies the new value for the
