Uwaga: The Not
                                 						Equals filter operator works the same as the equivalent filter operator in
                                 						Microsoft SQL Server or Oracle, and excludes null columns from comparison.
                                 						To include all records in a comparison using Not Equals, use the clause
                                 							
<value> IS
                                    							NULL. 
                                 
For example, you could create the
                                    							filter FilterByState as State Not Equal
                                       								'Middlesex' OR State IS NULL.
