在 SQL 中加入两个查询

Question

我有一个简单的查询：

SELECT t1.JOB_ID 
FROM 
(
  select 1 as JOB_ID 
  from JOBS2
) as t1 
INNER JOIN 
(
   SELECT 2 AS JOB_ID 
   from JOBS
) as t2 ON t1.JOB_ID = t2.JOB_ID;

我有这个错误：

Error: ORA-00933: SQL command not properly ended

是语法的原因吗？还是其他问题？

Answer 1

删除子查询名称前的 AS

SELECT t1.JOB_ID 
FROM 
(
  select 1 as JOB_ID 
  from JOBS2
) t1 
INNER JOIN 
(
   SELECT 2 AS JOB_ID 
   from JOBS
) t2 ON t1.JOB_ID = t2.JOB_ID;
