Help me create this Trigger - Microsoft SQL Server

Leonardo Almeida

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 Doc´s table the field Client
everytime it´s changed in the Client´s table.

Thanks for Attetion.

Something like this should work:

create trigger dbo.ATR_U_Clien ts
on dbo.Clients
after update
as

if @@rowcount = 0
return

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