WCF SQL SERVER ADAPTER Twin Cities Connected Systems User Group (Nov.17th, 2011) OVERVIEW
Classic SQL Adapter vs. WCF SQL Adapter • The classic SQL adapter does not support SQL Query Notification; the WCF SQL Adapter does. • For other differences, refer to: Thiago Almeida’s blog post at http://connectedthoughts.wordpress.com/2011/01/18/wcf-sql-versus-the-old-sql-adapter/ Richard Seroter’s SOA Patterns with BizTalk Server 2009 (Chapter 9) .

SQL Service Broker Verification • To verify whether Service Broker is enabled or not: SELECT is_broker_enabled FROM sys.databases WHERE name = ‘MyDB’; • To enable Service Broker functionality (if needed): ALTER DATABASE [MyDB] SET ENABLE_BROKER; or ALTER DATABASE [MyDB] SET ENABLE_BROKER WITH ROLLBACK IMMEDIATE; Twin Cities Connected Systems User Group (Nov.17th, 2011)

Caveats & Gotchas • The adapter only receives one notification if the SQL statement (e.g. INSERT) affects more than one row. • Consider the use of the NotifyOnListenerStart event to retrieve pending records after a network communication breakdown. • Double check the requirements and restrictions for SELECT statements in a query notification.
