計算された列を使用して別の列を計算しようとしています

Question

高さとインチの重さに基づいてBMIフィールドを計算しようとしています。私はあなたがやろうとしたものを見ることができると思い

SELECT CASE_NUM,HEIGHT_F AS HEIGHT_ft,HEIGHT_I AS HEIGHT_inches,WEIGHT_P AS WEIGHT_lbs,WEIGHT_O AS WEIGHT_oz, 
PRESS_SYST,PRESS_DIAST,HEART_RATE,RESP_RATE,WAIST_CIR,APPROVED_DATE,STAFF_ID, 
S.SORT_NAME AS SERVER_NAME,CAST(PRESS_SYST AS VARCHAR(5)) + '/' + CAST (PRESS_DIAST AS VARCHAR(5)) AS BP, 

HEIGHT_F * 12 + HEIGHT_I 
AS HEIGHT_TOTAL_IN 

FROM (
SELECT 
    (HEIGHT_TOTAL_IN * HEIGHT_TOTAL_IN/WEIGHT_P) * 703 AS BMI 

FROM AZCLCDEV A 
INNER JOIN CDCLIENT C 
ON A.CLIENT_ID = C.ID 
INNER JOIN CAEMP S 
ON A.STAFF_ID = S.ID 

Answer 1

...私は、サブクエリを書きましたが、何かが間違っています。このクエリを試す：

SELECT *, (HEIGHT_TOTAL_IN * HEIGHT_TOTAL_IN/WEIGHT_P) * 703 AS BMI 
FROM (
    SELECT CASE_NUM, HEIGHT_F AS HEIGHT_ft, HEIGHT_I AS HEIGHT_inches, 
      WEIGHT_P AS WEIGHT_lbs,WEIGHT_O AS WEIGHT_oz, 
      PRESS_SYST, PRESS_DIAST, HEART_RATE, RESP_RATE, WAIST_CIR, 
      APPROVED_DATE, STAFF_ID, S.SORT_NAME AS SERVER_NAME, 
      CAST(PRESS_SYST AS VARCHAR(5)) + '/' + CAST (PRESS_DIAST AS VARCHAR(5)) AS BP, 
      HEIGHT_F * 12 + HEIGHT_I AS HEIGHT_TOTAL_IN 
    FROM AZCLCDEV A 
     INNER JOIN CDCLIENT C 
      ON A.CLIENT_ID = C.ID 
     INNER JOIN CAEMP S 
      ON A.STAFF_ID = S.ID
