I have written the following trigger in SQL server: create trigger test_trigger on invoice

  • 0

I have written the following trigger in SQL server:

create trigger test_trigger
on invoice -- This is the invoice table
for insert
as
declare @invoiceAmount int    -- This is the amount specified in the invoice 
declare @custNumber int       -- This is the customer's id

--use the 'inserted' keyword to access the values inserted into the invoice table
select @invoiceAmount = Inv_Amt from inserted 
select @custNumber = cust_num from inserted


update customer
set amount = @invoiceAmount
where Id = @custNumber

Will this be able to run in MS Access or is the syntax different?

    The Access database engine (formerly called Jet) does not have triggers and regardless has no control-of-flow syntax e.g. a PROCEDURE must consist of exactly one SQL statement.

    Tell us what you really want to do and there could be an alternative syntax.

    For example, you could create a new key using a UNIQUE constraint on invoice, (cust_num, Inv_Amt), a FOREIGN KEY customer (id, amount) to reference the new key, a VIEW that joins the two tables on the FOREIGN KEY columns and exposing all four columns, then INSERT into the VIEW rather than the table ‘invoice’; you may want to use privileges to prevent INSERTs to the base table but user level security was removed from the new Access 2007 engine (called ACE).

    But, if you don’t mind me saying, I think your trigger doesn’t reflect a real life scenario. A column vaguely named ‘amount’ in table ‘customer’ to hold the most recent invoice amount? What about when the inserted logical table contains rows for more than one customer? As I say, I think you need to tell us what you are really trying to achieve.
