mysql - 对嵌套 SQL Oracle 查询中的多行值求和

Question

我想在下面的查询中对 T.CLS 和 CLS 的所有行求和，但我无法这样做，因为它显示的不是 Sony 组函数。 我该如何解决这个问题？

SELECT A.PROD,
          A.ID AS ACCOUNT,
          A.NAME AS NAME,
          T.PDATE AS DATE,
          A.CODE,
          T.CLS,
          CASE
              WHEN A.CODE != 'abc' THEN
                     (SELECT DISTINCT col
                      FROM table1
                      WHERE CODE2 = A.CODE
                        AND TOCODE = 'ABC'
                        AND ETYPE = 'S') * T.CLS
              ELSE CLS
          END AS EQB
   FROM UTTABLE T JOIN ACTABLE A ON T.AID = A.ID

可以使用coarse的解析函数:

SELECT A.PROD,
      A.ID AS ACCOUNT,
      A.NAME AS NAME,
      T.PDATE AS DATE,
      A.CODE,
      T.CLS,
      sum(T.CLS) over (partition by A.ID) "SUMM",
      count(T.CLS) over (partition by A.ID) "amount",
      CASE
          WHEN A.CODE != 'abc' THEN
                 (SELECT DISTINCT col
                  FROM table1
                  WHERE CODE2 = A.CODE
                    AND TOCODE = 'ABC'
                    AND ETYPE = 'S') * T.CLS
          ELSE CLS
      END AS EQB
FROM UTTABLE T JOIN ACTABLE A ON T.AID = A.ID

如果要使用GROUP BY，则所有字段(分组数据除外)都必须写入GROUP BY
