Hello Sir,

I created trigger as below

ALTER TRIGGER SetCreation_date ON dbo.Content_Header
after update
AS
update dbo.Content_Header set CreationDate=getdate()
GO

it updates all records, i want to be set getdate() on only updated records,

So,I tried like below

ALTER TRIGGER SetCreation_date ON dbo.Content_Header
after update
AS
update dbo.Content_Header set CreationDate=getdate() FROM UPDATED
GO

but doesnt work...

How can i set getdate on only updated record

Regards,

you should be using inserted or deleted tables for this


ALTER TRIGGER SetCreation_date ON dbo.Content_Header
after update
AS 
update c set 
c.CreationDate=getdate() 
FROM dbo.Content_Header c
INNER JOIN INSERTED i
ON i.OK= c.PK
GO

PK is your primary key column
