Question

This is what I have. It looks like MS’s example adn I can’t figure out why it’s not running. I get an Invaild column name ‘PlanID’ error on this line:

WHERE gm.PlanId = i.[PlandID]

I was under the impression INSERTED would contain the same fields as the Plan table. Maybe I’m way off – this is my first trigger!

PlanID is the primary key in the Plan table and is a foreign key to Measures. I’m basically looking to check when a row in Plan’s Status field is updated and then update the Status field in Measures.

CREATE TRIGGER utr_Plan_Cascade_Status
   ON  [dbo].[Plan]
   for UPDATE
AS 
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;

    IF(UPDATE([Status]))
    BEGIN
        UPDATE dbo.Measures
            SET [Status]= i.[Status]
        FROM dbo.Measures m, INSERTED i, DELETED d
            WHERE m.PlanId = i.[PlandID]

    END

END

Any help will be appreciated.

Answer 1

Why are you using old style joins?

You also don’t need the deleted table at all.

This should work for you

 UPDATE m
            SET m.[Status]= i.[Status]
        FROM dbo.Measures m
        JOIN INSERTED i ON m.PlanId = i.[PlandID]

Just as a FYI..IF(UPDATE([Status])) will fire if you do the following

Update Table set Status = Status

perhaps you want to add where m.Status <> i.Status to your WHERE clause

Also keep in mind that if that column is nullable you need to account for that in this where clause
