sql - 未知命令开始 SELECT ... 错误？

Question

我正在尝试在 Oracle 中运行以下命令

SELECT artistic_name 
FROM Artist 
INNER JOIN Groups ON artistic_name = Groups.group_name, Groups.group_name = ‘Frankensense’, OR Groups.group_name = ‘Jameson’;

错误是：SP2-0734: unknown command beginning "1) SELECT ..." - rest of line ignored.

我看不出这到底是什么问题。

有人有想法么？

谢谢。

Answer 1

首先，发布确切的错误（ORA-xxxxx 错误代码和错误消息的全文）总是有帮助的。

我怀疑你想要

SELECT artistic_name 
  FROM Artist 
       INNER JOIN Groups 
       ON artistic_name = Groups.group_name
 WHERE Groups.group_name IN ('Frankensense', 'Jameson');

您也可以将group_name谓词放在ON子句中

SELECT artistic_name 
  FROM Artist 
       INNER JOIN Groups 
       ON(     artistic_name = Groups.group_name
           AND Groups.group_name IN ('Frankensense', 'Jameson'));

Answer 2

告诉我们错误。同时，删除多余的逗号。

SELECT artistic_name 
FROM Artist
INNER JOIN Groups
  ON artistic_name = Groups.group_name
    AND Groups.group_name = 'Frankensense'
    OR Groups.group_name = 'Jameson';

您可能需要添加括号，具体取决于您希望 at "ON" 子句如何工作。

Answer 3

这应该工作，

SELECT artistic_name 
FROM Artist 
INNER JOIN Groups ON artistic_name = Groups.group_name 
  AND (Groups.group_name = 'Frankensense' OR Groups.group_name = 'Jameson')

JOIN或WHERE条件不需要逗号

Answer 4

看起来你打算有一个 WHERE 子句，并删除逗号：

 SELECT artistic_name 
 FROM Artist 
   INNER JOIN Groups ON artistic_name = Groups.group_name 
 WHERE Groups.group_name = 'Frankensense' 
    OR Groups.group_name = 'Jameson';
