17,635,381 | I am new to triggers

i want after an insert my trigger update ArefSms where tblSalesProd.SalesID=ArefSms.SalesID
for this propose i write below code

] | You need to specify `inserted` in the `update` statement. It is a table reference:
```
Update ArefSms
set qt=inserted.ProdQty
from inserted
where ArefSms.SalesID=inserted.SalesID;
``` | When updating tables from other tables (in this case `inserted`), I prefer the syntax using `JOINs`:
```
UPDATE Aref
SET Aref.qt=inserted.ProdQty
FROM ArefSms Aref
INNER JOIN inserted ON Aref.SalesID=inserted.SalesID
```
