Question

 SELECT CASE 
     WHEN age BETWEEN 1 AND 25 THEN '1-25' 
     WHEN age BETWEEN 26 AND 35 THEN '26-35' 
     WHEN age BETWEEN 36 AND 45 THEN '36-45' 
     WHEN age BETWEEN 46 AND 55 THEN '46-55' 
     WHEN age >= 56 THEN '56+' 
   END  AS Age_Range, 
   Sum(CASE 
         WHEN gender = 'Male' THEN 1 
         ELSE 0 
       END) AS "M Count", 
   Sum(CASE

我正尝试增加2列，分别是交易数和总销售额。我的桌子应该像这样：

您要扩展条件聚合。您的当前计数似乎是交易计数，除非那是表中的单独列。

查询如下：

SELECT (CASE WHEN age BETWEEN 1 AND 25 THEN '1-25' 
             WHEN age BETWEEN 26 AND 35 THEN '26-35' 
             WHEN age BETWEEN 36 AND 45 THEN '36-45' 
             WHEN age BETWEEN 46 AND 55 THEN '46-55' 
             WHEN age >= 56 THEN '56+' 
        END) as Age_Range, 
       Sum(CASE WHEN gender = 'Male' THEN 1 ELSE 0 END) AS "M Count",
       Sum(CASE WHEN gender = 'Male' THEN sales ELSE 0 END) AS "M Sales",
       Sum(CASE WHEN gender = 'Female' THEN 1 ELSE 0 END) AS "F Count", 
       Sum(CASE WHEN gender = 'Female' THEN sales ELSE 0 END) AS "F Sales", 
       Sum(CASE WHEN gender = 'Unk' THEN 1 ELSE 0 END) AS "Unk Count" 
       Sum(CASE WHEN gender = 'Unk' THEN sales ELSE 0 END) AS "Unk Sales" 
FROM dm_owner.v_individualbrand 
WHERE txn_date >= DATE '2018-01-01' AND
      txn_date < DATE '2019-01-01' AND
      brandcode = 'HT' 
GROUP BY (CASE WHEN age BETWEEN 1 AND 25 THEN '1-25' 
               WHEN age BETWEEN 26 AND 35 THEN '26-35' 
               WHEN age BETWEEN 36 AND 45 THEN '36-45' 
               WHEN age BETWEEN 46 AND 55 THEN '46-55' 
               WHEN age >= 56 THEN '56+' 
          END)
ORDER BY MIN(age);
