Question

I’m trying to write an SQL Trigger with the following approximate form:

CREATE TRIGGER TableABSync ON TableA
FOR INSERT AS

INSERT INTO TableB
        (col1, col2, col3, col4)
    SELECT
        PK_ColA, ColB, ColC - ColD, ColE * TableB.Col3
    FROM inserted

So I’d like to use the newly generated Col3 to calculate Col4. Will I have to do this in stages?

Cheers

Why dont you directly use something like :

CREATE TRIGGER TableABSync ON TableA
FOR INSERT AS

INSERT INTO TableB
        (col1, col2, col3, col4)
    SELECT
        PK_ColA, ColB, ColC - ColD, ColE *( TableB.ColC - TableB.ColD)
    FROM inserted
