Question

我收到以下内容：

查询错误：

错误：语法错误在或附近＆＃34;选择＆＃34;第4行:(选择remoteaddr， count（remoteaddr）remoteaddrCount

Select Tim1.remoteaddr,Tim1.remoteaddrCount,  Tim2.domain_id
From domain_visitors

(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

Answer 1

在domain_visitors之后和子查询之前，似乎您有一个热情的表名From。

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

希望这个答案可以帮到你。

Answer 2

您在FROM的第一个表格与创建Tim1的表达式

之间缺少逗号

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

Postgres查询错误：错误：语法错误在或附近＆＃34;选择＆＃34;
