Invalid object name [dbo].[TriggerName]

问题

I created a trigger named UPDATE_MERCHANDISE. The query completed with one error, a simple typo. I fixed the typo and changed the code to ALTER TRIGGER, but now when I try to execute it I receive the error

Invalid object name [dbo].[UPDATE_MERCHANDISE]

Why would it be valid when I created it, but not when I try to alter it? Any and all help/ideas would be appreciated.

Thanks.

ALTER TRIGGER [dbo].[UPDATE_MERCHANDISE] ON [dbo].[ORDERITEM]

AS
BEGIN
DECLARE @ITEMID VARCHAR(2)
DECLARE @TOTAL INT

--INSERT CASE
IF(EXISTS (SELECT * FROM INSERTED) AND NOT EXISTS (SELECT * FROM DELETED))

SELECT ITEMID, SUM(QUANTITY) AS TOTAL

    WHERE ITEMID = @ITEMID
    FETCH NEXT FROM INSERT_CURSOR INTO @ITEMID, @TOTAL

If you had a typo, most likely, the trigger never got created

Try CREATE TRIGGER instead of ALTER TRIGGER

By the way, generally, you remove the trigger and recreate, using something like.

IF Object_id('TRIGGER_NAME') is not null
    DROP TRIGGER Trigger Name
GO
CREATE TRIGGER TriggerName
AS
