Question

无法使用此SQL：

INSERT INTO final_tab (
    id_member_card
    ,points
    )
VALUES 
    (
        SELECT idMemberCard
        ,punti FROM (
        SELECT *
        FROM (
            SELECT idMemberCard
                ,SUM(amountOriginal) AS speso
                ,SUM(amountFinal) AS punti
            FROM transactions
            WHERE date_transaction_UTC BETWEEN '2018-01-01 00:00:00'
                    AND '2018-03-19 23:59:59'
            GROUP BY idMemberCard
            ) AS derived
        WHERE speso >= 50
        ) AS d2
    )

错误是

语法错误附近＆＃39; SELECT idMemberCard，punti FROM（SELECT * FROM（SELECT idMemberCard，SUM（amou＆＃39; at the line 6）

我哪里错了？谢谢

VALUES不需要INSERT . . . SELECT：

INSERT INTO final_tab (id_member_card , points) 
    SELECT idMemberCard , punti
    FROM (SELECT *
          FROM (SELECT idMemberCard , SUM(amountOriginal) AS speso, 
                       SUM(amountFinal) AS punti
                FROM transactions
                WHERE date_transaction_UTC BETWEEN '2018-01-01 00:00:00' AND '2018-03-19 23:59:59'
                GROUP BY idMemberCard
              ) AS derived
          WHERE speso >= 50
         ) t2;

您可以大大简化逻辑：

INSERT INTO final_tab (id_member_card , points) 
    SELECT idMemberCard , SUM(amountOriginal) AS speso, SUM(amountFinal) AS punti
    FROM transactions
    WHERE date_transaction_UTC >= '2018-01-01' AND 
          date_transaction_UTC < '2018-03-20'
    GROUP BY idMemberCard
    HAVING speso >= 50;

如果您不想将值实际存储在表中，也可以将其指定为视图。

Answer 2

您可以直接将其表达为：

INSERT INTO final_tab (id_member_card , points) 
SELECT idMemberCard , punti 
FROM (SELECT * FROM 
             ( SELECT idMemberCard , SUM(amountOriginal) AS speso,     
                      SUM(amountFinal) AS punti 
               FROM transactions
               WHERE date_transaction_UTC BETWEEN '2018-01-01 00:00:00' AND '2018-03-19 23:59:59'
               GROUP BY idMemberCard ) AS derived
WHERE speso >= 50

但是，您的核心逻辑将重写为：

INSERT INTO final_tab (id_member_card , points) 
SELECT idMemberCard ,  SUM(amountFinal) AS punti,
       SUM(amountOriginal) AS speso,     
FROM transactions
WHERE date_transaction_UTC BETWEEN '2018-01-01 00:00:00' AND '2018-03-19 23:59:59'
GROUP BY idMemberCard
HAVING speso > 50;

INSERT INTO另一个表FROM另一个选择不起作用
