Например: 

 food fee   admission fee 
 ------------------------
   100          0 
     0        100 
    50         50 
     0          0

Я хочу запрос, который игнорирует 0 (ноль) значений в обоих полях сборов. Поэтому вывод должен быть 

 100     0
   0   100
  50    50

Код 

WITH cteReports AS
(
    SELECT

        tblStudentFees.DivisionName, tblStudentFees.FoodFee,

Вам нужны скобки при использовании ИЛИ.

, например 

(tblStudentFees.AdmissionFee != 0.00 
AND tblStudentFees.FoodFee = 0.00) 
 OR (tblStudentFees.AdmissionFee = 0.00 
AND tblStudentFees.FoodFee != 0.00) 
 OR (tblStudentFees.AdmissionFee!= 0.00 
AND tblStudentFees.FoodFee != 0.00)

Более простой способ написать это будет: 

WHERE NOT (FoodFee = 0 AND AdmissionFee = 0)
...
