Question

我正在尝试将旧样式查询转换为ANSI。为什么顶级查询失败（错误：ORA-00933：SQL命令未正确结束）但底部版本有效？

SELECT
  JOBS.STARTED_DATE,
  JOB_SCHEDULE_TECHNICIANS.EMPLOYEE_NUMBER,
  JOB_SCHEDULE_TECHNICIANS.HOURS
FROM JOBS 
JOIN JOB_SCHEDULE_TECHNICIANS ON JOB_SCHEDULE_TECHNICIANS.JOB = JOBS.JOB 
WHERE 
  JOBS.STARTED_TIME BETWEEN to_date('2013-05-01', 'YYYY-MM-DD') 
  AND to_date('2013-05-03', 'YYYY-MM-DD')

SELECT
  JOBS.STARTED_DATE,
  JOB_SCHEDULE_TECHNICIANS.EMPLOYEE_NUMBER, 
  JOB_SCHEDULE_TECHNICIANS.HOURS 
FROM JOBS, JOB_SCHEDULE_TECHNICIANS 
WHERE 
  JOBS.STARTED_TIME BETWEEN to_date('2013-05-01', 'YYYY-MM-DD') 
  AND to_date('2013-05-03', 'YYYY-MM-DD')
  AND JOB_SCHEDULE_TECHNICIANS.JOB = JOBS.JOB

Answer 1

我认为上述 2 Query中没有任何问题。

我建议将分号（;）作为 Mathew Strawbridge 评论。

像这样：

SELECT
  JOBS.STARTED_DATE,
  JOB_SCHEDULE_TECHNICIANS.EMPLOYEE_NUMBER,
  JOB_SCHEDULE_TECHNICIANS.HOURS
FROM JOBS 
JOIN JOB_SCHEDULE_TECHNICIANS ON JOB_SCHEDULE_TECHNICIANS.JOB = JOBS.JOB 
WHERE 
  JOBS.STARTED_TIME BETWEEN to_date('2013-05-01', 'YYYY-MM-DD') 
  AND to_date('2013-05-03', 'YYYY-MM-DD')
; --  <- Here
SELECT
  JOBS.STARTED_DATE,
  JOB_SCHEDULE_TECHNICIANS.EMPLOYEE_NUMBER, 
  JOB_SCHEDULE_TECHNICIANS.HOURS 
FROM JOBS, JOB_SCHEDULE_TECHNICIANS 
WHERE 
  JOBS.STARTED_TIME BETWEEN to_date('2013-05-01', 'YYYY-MM-DD') 
  AND to_date('2013-05-03', 'YYYY-MM-DD')
  AND JOB_SCHEDULE_TECHNICIANS.JOB = JOBS.JOB

Oracle JOIN失败了
