Setting A Filter In The SELECT-statement

Is it possible to set a filter in the SELECT-statementpart?
Normaly you the filter is set in the WHERE-statementpart, but that is too late for me in my statement. Right after the SELECTing the field I want to set a filter to the query? Is it possible?

My statement looks like this now:
SELECT [DatabaseName$Item].No_,
[DatabaseName$Item].Description,
[DatabaseName$Sales Price HAG].[Unit Price],
[DatabaseName$Sales Price HAG].[Starting Date],
[DatabaseName$Sales Price HAG].[Starting Time],
[DatabaseName$Sales Price HAG].[Sales Code] (<== here on this item I want to set a filter)

FROM [DatabaseName$Item] INNER JOIN
[DatabaseName$Sales Price HAG] ON
[DatabaseName$Item].No_ = [DatabaseName$Sales Price HAG].[Item No_]
INNER JOIN (SELECT [Item No_], MAX([Starting Date]) AS MaxStartingDate, MAX([Starting Time]) AS MaxStartingTime
FROM [DatabaseName$Sales Price HAG] AS [DatabaseName$Sales Price HAG_1]
GROUP BY [Item No_]) AS SubQuery1
ON [DatabaseName$Sales Price HAG].[Item No_] = SubQuery1.[Item No_] AND
[DatabaseName$Sales Price HAG].[Starting Date] = SubQuery1.MaxStartingDate AND
[DatabaseName$Sales Price HAG].[Starting Time] = SubQuery1.MaxStartingTime

Thx for helping!
