Array(20) [ 767376,570025,436921,601819024,574564,202500,91204,4173849,506944,5041,… ]

我将相交方法用作：
managers_temp据我了解，相交给出了两个表的通用数据：
但是当我应用该查询时，我得到的输出为：
当我改用那个查询来获取公共数据时，我得到的是除重复数据之外的数据。既然如此，相交就得到了公共数据，但是为什么这里除了公共数据之外又要来数据呢？我在这里感到困惑，因为我的预期输出是：
select id,name,age from ot.managers_temp
intersect
select id,age from ot.managers_temp
这两个是通用数据，但除所有通用元素外，它向我显示数据吗？为什么会这样呢？
