Applies to:

Oracle Data Provider for .NET - Version to [Release 11.2 to 12.1]
Microsoft Windows x64 (64-bit)
Microsoft Windows (32-bit)


When BindByName property of OracleCommand class is set to true, ODP.NET attempts to interpret placeholders in a SQL statement by their parameter names.
In this behavior, ODP.NET Unmanaged driver checks all parameters and would return the error ORA-1036 if a parameter which does not match any placeholder name in the SQL statement has been bound.

According to the following sample code, although the parameter named "param2" is 'unnecessary' bound for the SQL execution, ODP.NET Unmanaged driver redundantly checks it and throws ORA-1036.

 The above code works with using ODP.NET Managed driver.
