WORKAROUND

The problem does not occur if the call to the Stored Procedure is passed as command text. The following C# code excerpt can be used as an example:

OleDbCommand myCommand = new OleDbCommand("CALL <stored procedure name>(?)", myConnection);
myCommand.CommandType = CommandType.Text;

MORE INFORMATION

ADO.NET sends a command in the following format to the OLE DB Provider when calling a Stored Procedure:

EXEC <stored procedure name> ?

Previous versions of ADO send the same command in the following format when calling a Stored Procedure:

EXEC <stored procedure name>

The SQL parser in the Microsoft OLE DB Provider for DB2 had to be updated to correctly parse the ? included in the ADO.NET format of the command.
