Question

尝试执行此SQL语句：

SELECT B.CardType, Count(*) as TotalSales
 FROM Sales.SalesOrderHeader A
 LEFT OUTER JOIN Sales.CreditCard B
 ON A.CreditCardId=B.CreditCardId
 WHERE B.CardType like ('%Vista%') 
 IN ExpMonth=10 AND ExpYear=2006
 GROUP BY B.CardType

我收到以下错误：

Msg 156，Level 15，State 1，Line 6语法不正确关键字＆＃39; IN＆＃39;。

有人可以解释为什么以及如何解决它？

Answer 1

你错过了条件运算符（AND/OR）。它应该是

WHERE B.CardType like '%Vista%'
AND ExpMonth=10
AND ExpYear=2006

您应该将这些条件移至JOIN ON子句，而不是

 LEFT OUTER JOIN Sales.CreditCard B
 ON A.CreditCardId=B.CreditCardId
 AND B.CardType like ('%Vista%') 
 WHERE A.ExpMonth=10 
 AND A.ExpYear=2006
 GROUP BY B.CardType

SQL语句出错（使用JOIN，LIKE和IN）
