Bug#: 2059 (PSSWebData)
Consider the following scenario. You load the Microsoft SQL Server 2000 Driver for JDBC in an application. Then, you load the Microsoft SQL Server 2005 JDBC Driver in the same application. In this scenario, when you try to connect to a SQL Server 2005 database by using a SQL Server 2005 JDBC Driver URL, the connection is established by using the Microsoft SQL Server 2000 Driver for JDBC. If you subsequently run a query, you receive the following error message:
If you establish a connection to a SQL Server 2000 database, you may not receive any error message, and the fact that the wrong driver is being used may be unnoticed. You experience this problem when the SQL Server 2000 Driver for JDBC is loaded before the Microsoft SQL Server 2005 JDBC Driver is loaded in the application.
[Microsoft][SQLServer 2000 Driver for JDBC][SQLServer]The incoming tabular data stream (TDS) remote procedure call (RPC) protocol stream is incorrect. Parameter 1 (""): Data type 0x38 is unknown.
This problem occurs because faulty name resolution occurs in the SQL Server 2000 JDBC driver. The SQL Server 2000 JDBC driver accepts connection URLs from the SQL Server 2005 JDBC Driver. The SQL Server 2005 JDBC Driver connection string URLs start with the following string:
jdbc:sqlserver://ConnectionStringThe SQL Server 2000 Driver for JDBC should only accept connection string URLs that start with the following string:
jdbc:microsoft:sqlserver://ConnectionStringHowever, the SQL Server 2000 Driver for JDBC also accepts connections that have the following format:
jdbc:sqlserver://ConnectionStringThe exception occurs because the SQL Server 2000 Driver for JDBC is not designed to connect to a SQL Server 2005 database.
