Question

我正在尝试执行下一个：

SELECT l.id AS id
FROM s.process AS l 
JOIN s.item AS r ON l.id = r.id;

但我得到：

Query execution failed
Reason:
SQL Error [933] [42000]: ORA-00933: SQL command not properly ended

使用：

Answer 1

定义 table/view 的别名时必须删除 AS:

SELECT l.id AS id
FROM s.process l 
JOIN s.item r ON l.id = r.id;

Answer 2

Oracle 支持 table 别名，但它在 SELECT 列表中支持 AS，但在 FROM 列表中不支持：

SELECT l.id AS id
FROM s.process l 
JOIN s.item r ON l.id = r.id;
