SUM(dbo.TABHDBH.DOITRA) AS DTRA, dbo.TABHDBHCT.GIABAN AS DONGIA, CASE TABHDBH.DOITRA WHEN 0 THEN (TABHDBHCT.SOLUONG * TABHDBHCT.GIABAN)
ELSE (TABHDBHCT.SOLUONG - TABHDBH.DOITRA) * (TABHDBHCT.GIABAN) END AS THANHTIEN, dbo.TABHDBHCT.GIABAN * dbo.TABHDBHCT.GIAMGIA / 100 AS GGIA,
CASE TABHDBH.DOITRA WHEN 0 THEN (TABHDBHCT.SOLUONG * TABHDBHCT.GIABAN) - (dbo.TABHDBHCT.GIABAN * dbo.TABHDBHCT.GIAMGIA / 100) 
ELSE ((TABHDBHCT.SOLUONG - TABHDBH.DOITRA) * (TABHDBHCT.GIABAN)) - (dbo.TABHDBHCT.GIABAN * dbo.TABHDBHCT.GIAMGIA / 100) END AS TONGCONG,
