Check this article ( shahriarnk.com/Shahriar-N-K-Research-Embedding-SQL-in-C-Sharp-Java.html ) for details on how to connect to SQL Server database from C#.NET database applications as well as Java database applications. It also describes how to pass embedded SQL queries (INSERT, UPDATE, DELETE), calling stored procedures, pass parameters etc.

If you are seeing the mentioned exception means that you are giving some mistake in database connectivity.Just post you code for database connectivity and your update command so that I can trace the error.
