当我尝试执行以下查询时，我不断收到错误:
SELECT C.CustomerID WITH C.CustomerName WITH O.OrderDate WITH O.TotalOrderAmount
FROM CUSTOMERS C
LEFT JOIN [ORDERS] 0
ON C.CustomerID=O.CustomerID
UNION
SELECT C.CustomerID, C.CustomerName, O.OrderDate, O.TotalOrderAmount
FROM CUSTOMERS C
RIGHT JOIN [ORDERS] 0
On C.CustomerID-O.CustomerID;
下面是我在 MySQL 中收到的代码:
Error Code: 1064. You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '[ORDERS] 0 ON C.CustomerID=O.CustomerID UNION SELECT C.CustomerID, C.CustomerN' at line 3
非常感谢您为纠正此错误提供的任何帮助。
最佳答案
只需执行完全连接而不是并集。应该在这里给你相同的结果:
SELECT C.CustomerID, C.CustomerName, O.OrderDate, O.TotalOrderAmount
FROM CUSTOMERS C
full JOIN [ORDERS] 0
On C.CustomerID-O.CustomerID
关于mysql - MySQL 高级查询代码 1064 出错，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/50456200/
