There is a bug that has been driving me insane. I thought I was doing something wrong but apparently it's a bug in Microsoft SQL Server JDBC driver when using SQL Server 2000.
I had a bunch of sprocs that were failing for no apparent reason. I thought it was code change to incorporate a database connection pool. Coincidentally I updated the Microsoft JDBC driver at the same time and forgot about it.
Oddly enough the fix is to add "SET NOCOUNT ON" to stored procedures and then things run as expected.
The statement did not resturn a ResultSet
