在视图中运行时，sql 查询需要更多时间

HI all,

我有一个巨大的 sql 查询。当我将该查询放入存储的 Proc 中时，执行需要 5 秒，我将其作为查询运行，需要 4-5 秒，但当我在视图中运行它时，需要 5 分钟。

请告知为什么它在视图中运行那么慢

sql查询如下：

根据您的评论，我怀疑您点击了“谓词推入“问题（搜索这个短语）

观察... LEFT JOIN 上的 WHERE 将其更改为 JOIN

LEFT JOIN RefCountry As DestRefCountry...
....
where (DestRefCountry.RN_Desc = 'United States')
