RESOLVE UPDATE triggers fire before each row is updated. The syntax for a RESOLVE UPDATE trigger is as follows:

CREATE TRIGGER trigger-name
RESOLVE UPDATE
OF column-name ON table-name 
[ REFERENCING [ OLD AS old-val ]
   [ NEW AS new-val ]
     [ REMOTE AS remote-val ] ] 
FOR EACH ROW 
BEGIN
   ... 
END

The REFERENCING clause allows access to the values in the row of the table to be updated (OLD), to the values the row is to be updated to (NEW) and to the rows that should be present according to the VERIFY clause (REMOTE). Only columns present in the VERIFY clause can be referenced in the REMOTE AS clause; other columns return an error.

The CURRENT REMOTE USER special value is set by the receive phase of SQL Remote when it is applying messages to the database. The CURRENT REMOTE USER special value is most useful in triggers to determine whether the operations being applied are being applied by the receive phase of SQL Remote, and if they are, which remote user generated the operations being applied.
