       OUTER JOIN

        OUTER JOIN

        (SELECT j1.*, d.Date

   ON c1.SK_Fact_MEDIAKPI_ID = c2.SK_Fact_MEDIAKPI_ID
   WHERE d.Date >= '2015-01-01';

间距也变得太可怕了。出了什么问题 - 有了这么多联接，这个错误大多没有意义。

我收到一个错误，称为156错误 - JOIN附近的语法错误

一个问题 - 哪个加入？

据我所知，嵌套的从属子查询是合法的。想法？

（另外，这个尺寸，让我很难发布。为什么要堆叠为什么？）

Answer 1

您只是为im说OUTER JOIN，但您需要指定哪种类型。它们可以是JOIN，RIGHT OUTER JOIN或LEFT OUTER JOIN。

有关不同FULL OUTER JOIN类型的更多信息，请参阅此帖子：What is the difference between "INNER JOIN" and "OUTER JOIN"?

Message156关键字附近的Incorect语法＆＃39;加入＆＃34; / SQL Server（和哪些连接？）
