Sql Postgres案例语句错误

我正在尝试创建一个基于职位发布状态的Postgres案例陈述。例如：

• 当

  状态

  为

  “关闭”

  时，我需要

  更新时间戳与
  创建时间戳之间的天数差

• 当

  状态

  为

  'Open'

  或

  'Pending'

  时，我想从当前时间戳中减去在

  时间戳处创建的
  

到目前为止，我创建的查询如下所示：

Select users.first_name || " " || users.last_name,
users.email,
organizations.name,
organizations.vertical,
jobs.name,
jobs.id
(Case
When jobs.status = 'Closed' Then jobs.updated_at - jobs.created_at Else 'Not Closed') END AS days_to_hire,
(Case
When jobs.status IN ('Open,'Pending') Then current_timestamp - jobs.created_at Else 'Closed_or_Deleted') END AS days_open,
FROM organizations
JOIN users on organizations.id = users.organization_id
JOIN jobs on user.id= jobs.user.id

但它并不像我预期的那样起作用：

错误：语法错误位于或接近“）”

我还不知道为什么

任何帮助都将不胜感激。

简短回答 查询中有三个语法问题：

缺少的逗号

您的

案例

语句中的右括号放错了位置

第二个

CASE

语句中的未终止字符串文字

我注意到以下每一点：

Select users.first_name || " " || users.last_name,
users.email,
organizations.name,
organizations.vertical,
jobs.name,
-- Missing comma added below.
jobs.id,
--jobs.id
-- Closing paren moved to after `END` below.
(Case
When jobs.status = 'Closed' Then jobs.updated_at - jobs.created_at Else 'Not Closed' END) AS days_to_hire, 
--(Case
--When jobs.status = 'Closed' Then jobs.updated_at - jobs.created_at Else 'Not Closed') END AS days_to_hire,
-- Closing paren moved to after `END` and a closing single quote added
-- to terminate the string literal 'Open' below.
(Case
When jobs.status IN ('Open','Pending') Then current_timestamp - jobs.created_at Else 'Closed_or_Deleted' END) AS days_open,
--(Case
--When jobs.status IN ('Open,'Pending') Then current_timestamp - jobs.created_at Else 'Closed_or_Deleted') END AS days_open,
FROM organizations
JOIN users on organizations.id = users.organization_id
JOIN jobs on user.id= jobs.user.id

补遗 此外，您的查询很难以格式化的方式读取。这使得调试变得更加困难

考虑另一种利用缩进和一致的关键字大小写（即小写与大写）的方法：

更容易阅读和调试，我想你会同意的

就个人而言，我不喜欢

CASE

语句周围的括号，但与良好、一致地使用缩进和关键字大小写相比，这是一个次要的选择。

欢迎使用！请务必指出您得到的确切语法错误。我包括了在测试您的查询时看到的第一个错误，但为了清楚起见，您应该在问题中包含特定的错误消息。@13ISPaulGeorge:如果这令人满意地回答了您的问题，请将其标记为已接受。谢谢
