Sybase中JOIN和Inner JOIN的区别

Question

我有如下查询。我不明白下面代码中使用的 join 和 inner join 之间的区别。他们不一样吗？这是为 Sybase 编写的。请帮我看看区别。

SELECT
   count(distinct c.stuID ) as cnt 
FROM
   tableC c 
   Inner Join
      tableB b 
      On c.otherID = b.otherID 
   Inner Join
      tableX gd 
      On b.otherID = gd.otherID 
   Inner Join
      tableY g 
      On gd.groupID = g.GROUPID 
      and g.GROUPTYPEID in 
      (
         1,
         3
      )
   JOIN
      tableZ d 
      on c.OPID = d.OPID 
   JOIN
      tableM e 
      on c.OTHERID = e.otherID 
      and c.stuID = e.stuID 
      and DATEDIFF(..........)

根据标准INNER JOIN=JOIN。我想，Sybase并没有违反这个规则
