Postgresql 查询中的Postgres错误：错误：“选择”处或附近的语法错误

我收到以下消息：

查询中出错：

错误：选择行4处或附近出现语法错误：选择remoteaddr， countremoteaddr remoteaddrCount

---

似乎在子查询之后和之前都有大量的表名domain_访问者

让我们再试一次

Select Tim1.remoteaddr,Tim1.remoteaddrCount, Tim2.domain_id From 
(Select remoteaddr, count(remoteaddr) remoteaddrCount From domain_visitors Group by remoteaddr Having count(remoteaddr)>500) Tim1
JOIN 
(Select distinct remoteaddr, domain_id From domain_visitors) Tim2 ON Tim1.remoteaddr=Tim2.remoteaddr

---

希望这个答案能对您有所帮助。

在FROM中的第一个表和创建Tim1的表达式之间缺少一个逗号

---

是的，这是糟糕的语法。如果你告诉我们你想要实现什么，也许有人可以帮助你。你需要以某种方式加入这些派生表。从域\访客加入选择。。。作为tim1上的tim1。某些列=域访问者。某些列其他列加入选择。。。tim2 on Tim1.remoteaddr=tim2.remoteaddr非常感谢你

Select Tim1.remoteaddr,Tim1.remoteaddrCount, Tim2.domain_id From 
(Select remoteaddr, count(remoteaddr) remoteaddrCount From domain_visitors Group by remoteaddr Having count(remoteaddr)>500) Tim1
JOIN 
(Select distinct remoteaddr, domain_id From domain_visitors) Tim2 ON Tim1.remoteaddr=Tim2.remoteaddr

Select Tim1.remoteaddr,Tim1.remoteaddrCount, Tim2.domain_id 
From domain_visitors,  -- <-- MISSING COMMA 
  (Select remoteaddr, count(remoteaddr) remoteaddrCount 
     From domain_visitors 
     Group by remoteaddr 
     Having count(remoteaddr)>500) Tim1,
  (Select distinct remoteaddr, domain_id 
     From domain_visitors) Tim2 
Where Tim1.remoteaddr=Tim2.remoteaddr
