FIX: Incorrect data is returned when you change the binding order of two similarly-named output parameters in an application that uses the ODBC driver in Windows XP Service Pack 2Article ID: 916528 SYMPTOMSConsider the following scenario:
For example, assume that you have a stored procedure that returns parameter values that are named @a1 and @a. In the application that uses the ODBC driver, you bind to @a first and then bind to @a1. In this scenario, the values are returned correctly. However, if you bind to @a1 first and then bind to @a, the parameter values are returned incorrectly. Note If the shorter of the parameter names is not contained in the other parameter name, the parameter values are always returned correctly. For example, the parameter values are returned correctly if you use @a and @b or if you use @a1 and @a2. CAUSEThis problem occurs because there is an incorrect comparison
of parameter names in the Microsoft SQL Server ODBC driver and in the SQL OLE
DB provider. RESOLUTION A supported hotfix is available from Microsoft. However, this hotfix is intended to correct only the problem that is described in this article.
