Help me Please to Create this TRIGGER

Hi everybody,

How can I Update a field from another table by Trigger? Can someone send me the statment to do it?

I have a table called Clients with fields : ID_Clients, Client
And Another called Doc with fields : ID_Doc, ID_Clients, Client

These tables are in different databases and I would like to esure the integrity by add a Trigger to update in Docs table the field Client everytime its changed in the Clients table.

Thanks for Attetion.

Here is some sample code:

CREATE TRIGGER YourTrigger ON dbo.YourTable
FOR UPDATE
AS
update DBName.DBTable
set YourField = inserted.YourField
from DBName.DBTable
inner join inserted on DBName.DBTable.KeyField = inserted.KeyField

Please read about triggers in Books Online and then post again if you have a specific question.

Something like this should work:

create trigger dbo.ATR_U_Clients
on dbo.Clients
after update
as

if @.@.rowcount = 0
return

update OtherDatabase.dbo.Doc
set Client = i.Client
from OtherDatabase.dbo.Doc d
join inserted i
on d.ID_Clients = i.ID_Clients
