The underlying ODBC driver does not support returning stored procedure parameter information, or the command text is not a valid stored procedure name, or the CommandType specified was not CommandType.StoredProcedure.
DeriveParameters overwrites any existing parameter information for the OdbcCommand.
DeriveParameters requires an additional call to the data source to obtain the information. If the parameter information is known in advance, it is more efficient to populate the parameters collection by setting the information explicitly.
You can only use DeriveParameters with stored procedures. You cannot use DeriveParameters to populate the OdbcParameterCollection with arbitrary Transact-SQL statements, such as a parameterized SELECT statement.
