SQL Server / T-SQL Tutorial Scenario:
How to get random rows from SQL Server Table

Scenario:
You are working as SQL Server developer. You are asked to provide sample random data from dbo.Customer table. You might asked to provide random 100 rows or some percent of total data from table. What query you will use to provide required output?

Solution:
In previous post, we learnt how to get top n rows from table. We can either provide row count or percent of records we want to get from a table by using TOP in our select query.

We can use the same Top clause but as we are asked to provide the random records, we need to sort them randomly first. We can use newid() function in order by clause to sort them randomly.
