Question

Using Great Plains here and one of our users keeps screwing up customer data so we want to put a trigger on the customer table and so we can find out who it is.

Anyway, I created a table called audit_RM00101 as follows:

DATE        nchar(10)   
CUSTNMBR    char(15)    
CUSTNAME    char(65)    
UPSZONE     char(3) 
SALSTERR    char(15)    
USERID      nchar(100)

I want to capture those same fields from the table I want to audit so I wrote the trigger as follows:

CREATE TRIGGER CatchCustomerRegionUpdate
ON RM00101
FOR UPDATE
AS
DECLARE @UserID VARCHAR(128)
SELECT @UserID = system_user
INSERT INTO audit_RM00101 
SELECT DATE, CUSTNMBR, CUSTNAME, UPSZONE, SALSTERR, @UserID FROM UPDATED

The trigger gets created just fine but when I try to test it by updating a customer record in Great Plains, Great Plains throws up an ugly error and the trigger doesn’t get fired.

What am I doing wrong here?

Thanks.

Answer 1

in a trigger, you get the DELETED and INSERTED tables, there is no UPDATED, so replace FROM UPDATED with FROM INSERTED

also try to fix your USERID column, your audit_RM00101.USERID is a nchar(100) while @UserID is a VARCHAR(128).

EDIT based on OPs comment: Ah, so there is no way to audit when a table is updated by using a trigger?

• in a trigger when deleting, DELETED is populated, but INSERTED is empty
• in a trigger when updating, DELETED is populated with the original value, and INSERTED is populated with the newly updated values
• in a trigger when inserting, DELETED is empty, but INSERTED has the newly inserted values
