Event Mechanism in SQL Server 2008

Question

I have a windows service that constantly queries a table in DB1 and if any changes are found in it, it transfers those changes to DB2. For that, it constantly queries the DB1.

Is there any mechanism by which I can subscribe to an event in DB1 such that any changes in table is notified to the window service ?

The tables in DB1 are capture tables which have only the changed values.

Answer 1

Yes, there is such a mechanism, named Notification services, but it only valid for sql 2005, in 2008 you can use the well known other options:

• SSIS
• replication
• Log shipping
• mirroring
• custom triggers and modifications queue tables

which need not the intermediate services to run with, except the last one
