ORACLE SQL错误-ORA-00933-执行联接操作-DBeaver

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;

但是我得到了：

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

使用：

• DBeaver
• ojdbc7.jar作为驱动程序

Answer 1

定义表/视图的别名时，您必须删除AS：

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

Answer 2

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

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