Select Random Rows from a Table – SQL Server

There are multiple ways to randomly select rows from a table. In this blog post, I will show two ways of doing so:

Method 1: Random Number of Rows

DECLARE @n int
SET @n=RAND()*10
SELECT TOP (@n) * FROM sysobjects


Method 2: Random Number of Rows as well as Data

DECLARE @n int
SET @n=RAND()*10
SELECT TOP (@n) * FROM sysobjects


The second method is easy to use and fetches data more randomly.

I am not able to follow what is difference in Method1 and 2. Can you explain in detail

Its interesting that you use sysobjects here although I am not sure why. Can't I just say?

SELECT top 10 percent * from [tablenaame] order by newid()
