Question

CREATE TRIGGER dbo.YourTrigger
ON a
AFTER UPDATE
AS
BEGIN
SET NOCOUNT ON;

IF NOT UPDATE(name)
RETURN

UPDATE d
set upload = 1
FROM d

This is the code, but it’s not working the way i want it. in this case its updating my upload field from Table (d) when every any record change in table (a) .
i want upload field in table (d) to be change only when (name field) change in Table (a).

You use the special Inserted and Deleted tables inside a trigger to identify which rows have been affected. For an update trigger, Deleted contains the “before” version of the rows and Inserted contains the “after” version of the rows.

CREATE TRIGGER dbo.YourTrigger
ON a
AFTER UPDATE
AS
BEGIN
    SET NOCOUNT ON;

    IF UPDATE(name)
        UPDATE d
            set upload = 1
            FROM Inserted i
                INNER JOIN Deleted de
                    ON i.EmpId= de.EmpId
                INNER JOIN d
                    ON i.EmpId= d.RecId
            WHERE i.name <> de.name
END
