sql-server - SQL Server 存储过程缓存

Question

我正在尝试通过两种不同的方法执行相同的选择。

首先通过使用存储过程的表值函数

SELECT * FROM dbo.DF_PRODUCTS();

二openquery是通过执行存储过程

SELECT * 
FROM openquery([servername], 
               'SET FMTONLY OFF exec DatabaseName.dbo.My_StoredProcedure')

问题是我得到了各种结果，我认为问题出在存储过程缓存中。谁能帮我这个？

If you're getting different results from running the exact same code, and the 'only' (perceived) difference is that you are running one through an OPENQUERY command, do a sanity check and confirm that the OPENQUERY([servername]...) is definitely running against the same server as your first query.

The likeliest scenario is that your linked server is different to the one you're running against locally - e.g. you're running against a local database versus a development/test/staging/live database.
