u have same id for the rows u want to update in the two databases,then when ever the row is updated write a query for the database2 at the same time.
May be u can get a better answer in databases forum.

Sorry Johnny.g
Just wonder, Why do you want to change your code ?
I think your code is already correct.
If I were you I will use that code.
