Question

I’m creating a trigger for a table, and I have the following statement:

UPDATE [dbo].ConsignmentTripBreakdown SET VehicleTypeID = CONVERT(bigint,LTRIM(RTRIM(VehicleType)))
WHERE [dbo].ConsignmentTripBreakdown.ID IN (SELECT ID FROM Inserted)

Problem is, there is no ‘ID’ field on the ConsignmentTripBreakdown – instead there’s a composite key on 3 fields. How would I rework the where clause for this?

Answer 1

UPDATE
  [dbo].ConsignmentTripBreakdown
SET
  VehicleTypeID = CONVERT(bigint,LTRIM(RTRIM(inserted.VehicleType)))
FROM
  [dbo].ConsignmentTripBreakdown
INNER JOIN
  inserted
    ON  inserted.pk_part1 = ConsignmentTripBreakdown.pk_part1
    AND inserted.pk_part2 = ConsignmentTripBreakdown.pk_part2
    AND inserted.pk_part3 = ConsignmentTripBreakdown.pk_part3
