So ... Having 2 # 0

????

>>A simple question about use of the HAVING phrase. Here's a sample SELECT statement
>>

Select  Partno		;
>>	, Sum (RealCost)	As RealCost		;
>>	, Sum (PostedCost) 	As PostedCost	;
>>	, Sum (RealCost - PostedCost)	As Variance		;
>>	, Sum (1)		As Count		;
>>	, Sum (NItems)	As NItems		;
>>	;
>>	from c_Source	                                          ;								;
>>	group By 1	;	;
>>	into Cursor c_Browse Readwrite

>>I'd like to be able to reference the RealCost field in the result in the HAVING phrase ... HAVING RealCost # 0 ... but I get an error message because of the name conflict with the field RealCost in the source cursor.
>>
>>How can I refer to the RealCost field in the result cursor (in the HAVING phrase)?

>Refer to it by position in the list, that is, field #, not name.
