SQL查询数据库的Microsoft SQL Server

Question

我的查询是不是在所有的工作，并一直在努力，看看出了什么问题，但无法找到它。说有两个值是相同的，但说实话，我尽我所能去校对我的代码：

正如你所看到的所有表和值相关，与内加入和外部连接，以补充表。这是一个报告

Answer 1

您的查询有多个问题。

1) Problem with parenthese (too '(') 
2) You use left outer join on table and you test a zone of this table -> null will be excluded like it 
3) Multiples Zones in your select with same name 
4) Quotes for zones and alias for tables are not necessary 

尝试此查询remainded：
