i have two tables. 1st table gets the information from as400, then moves the data to table 2 at sql 2000 server. I need to see when as400 updates\changes or inserts new information to table 1 how to update\change or insert into table 2?

You could make a trigger on table1.

Write a trigger on table 1 for UPDATE,DELETE, INSERT

It will be something like

CREATE TRIGGER table_IUD ON table1
AFTER INSERT,UPDATE,DELETE
AS
BEGIN

IF EXISTS (SELECT * FROM INSERTED)
AND NOT EXISTS(SELECT * FROM DELETED)
BEGIN
INSERT INTO table2
SELECT your fields 
FROM INSERTED i
END

IF EXISTS (SELECT * FROM INSERTED)
AND EXISTS(SELECT * FROM DELETED)
BEGIN
UPDATE t
SET t.field1=i.field1,t.field2=i.field2,...
FROM table2 t
INNER JOIN INSERTED i
ON i.FKCol=t.PKCol
END

IF NOT EXISTS (SELECT * FROM INSERTED)
AND EXISTS(SELECT * FROM DELETED)
BEGIN
DELETE t 
FROM table2 t
INNER JOIN DELETED d
ON d.FKCol=t.PKCol
END

END

How frequently do you need to see the changes?
