SQL Server - Dirty Reads Pros & Cons

Question

Why should I or shouldn\'t I use dirty reads:

set transaction isolation level read uncommitted

in SQL Server?

Answer 1

The Thing is when you want to read the data before committing, we can do with the help of set transaction isolation level read uncommitted, the data may, or may not change.

We can read the data by using the query:

Select * from table_name with(nolock) 

This is applicable to only read uncommitted isolation level.
