ORA-00923：未找到FROM关键字

Question

我有以下代码，并且收到错误： ORA-00923：在第四个选择（ * ）处找不到FROM关键字。有谁知道为什么？

我搜索了其他帖子，但没有找到我的解决方案。

select plan_date as Week,
      plan_date+7 as "Week + 7",
      plan_date+14 as "Week + 14",

from smart_plan p
order by plan_tower, plan_rice_type, plan_date

Answer 1

as Target_FD_Count后没有逗号。你需要在那里添加一个逗号。

(select count(*)
   from smart_rice_cooker rc
   where rc.tower = p.plan_tower and
         rc.rice_type = p.plan_rice_type and
         rc.status <> 'Cancelled' and
         rc.actual_fd_date is null and
         rc.target_fd_date between p.plan_start_date and p.plan_end_date
   ) as Target_FD_Count, -- <-- Comma here

   (select count(*)
   from smart_rice_cooker rc
   where rc.tower = p.plan_tower and
         rc.rice_type = p.plan_rice_type and
         rc.status <> 'Cancelled' and
         rc.actual_td_date between p.plan_start_date+7 and p.plan_end_date+7
  ) as Delivered_TD_Count,

您在别名Target_FD_Count之后缺少逗号。通常，当您发现此错误时，请检查您选择的逗号。
