  1. WCF SQL SERVER ADAPTER Twin Cities Connected Systems User Group (Nov.17th, 2011) Implementing Polling and Event-Driven Consumers { by Juan I. Arriaga }

  2. Agenda • Overview of the WCF SQL Adapter • BizTalk examples • A case study of using the WCF SQL Adapter outside of BizTalk • Questions & answers Twin Cities Connected Systems User Group (Nov.17th, 2011)

  3. WCF SQL SERVER ADAPTER Twin Cities Connected Systems User Group (Nov.17th, 2011) OVERVIEW

  4. 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) .

  9. WCF SQL Adapter Installation Download & install: • WCF LOB Adapter SDK SP2 • Microsoft BizTalk Adapter for SQL Server (WCF SQL Adapter) NOTE: (1) The WCF SQL adapter is also available as part of the BizTalk Adapter Pack. (2) A BizTalk license is required. Twin Cities Connected Systems User Group (Nov.17th, 2011)

  18. 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)

  34. 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.
