SQL语法错误（从事务代码为211＆amp; 292的account_ID中排除事务代码为293的account_ID）

SELECT *
FROM 
    (SELECT ACCOUNT_ID
     FROM Transaction_Data_Flexi
     WHERE TRAN_CODE = 211 OR TRAN_CODE = 292) AS trn1
LEFT JOIN
    (SELECT ACCOUNT_ID
     FROM Transaction_Data_Flexi
     WHERE TRAN_CODE = 293) AS trn2
WHERE 
    trn2.ACCOUNT_ID NOT IN trn1.ACCOUNT_ID
GROUP BY 
    ACCOUNT_ID

Answer 1

您错过了加入条件ON。如果您不打算指定条件，请使用CROSS JOIN代替LEFT JOIN。

还会有另一个错误 - 对于GROUP BY子句，您需要指定要分组的列。

    GROUP BY  trn1.account_id, trn2.account_id

Answer 2

我建议您使用group by和having：

执行此操作

SELECT ACCOUNT_ID
FROM Transaction_Data_Flexi
GROUP BY ACCOUNT_ID
HAVING SUM(IIF(TRAN_CODE = 211, 1, 0)) > 0 AND
       SUM(IIF(TRAN_CODE = 292, 1, 0)) > 0 AND
       SUM(IIF(TRAN_CODE = 293, 1, 0)) = 0;

这将检查给定事务的代码。 having条件验证代码。

谢谢大家的帮助！是的你应该工作，但我想尝试使用＆＃34; NOT IN＆＃34;声明，我已经更新了查询，如下所示。我仍然有问题在＆＃34;＆＃34;＆＃34;附近？中间的陈述：

SELECT trn1.ACCOUNT_ID
FROM 
(
SELECT ACCOUNT_ID
FROM Transaction_Data_Flexi
WHERE TRAN_CODE = 211 OR TRAN_CODE = 292
) AS trn1
WHERE ACCOUNT_ID NOT IN 
(
SELECT ACCOUNT_ID
FROM Transaction_Data_Flexi
WHERE TRAN_CODE = 293
) AS trn2
GROUP BY ACCOUNT_ID

SQL语法错误（从事务代码为211＆amp; 292的account_ID中排除事务代码为293的account_ID）
