What are Isolation Levels?

An isolation level determines the degree of isolation of data between concurrent transactions. The default SQL Server isolation level is Read Committed.

Following are the other isolation levels (in the ascending order of isolation):

  1. Read Uncommitted
  2. Read Committed
  3. Repeatable Read
  4. Serializable

One can set isolation levels at connection level using the following sql
SET TRANSACTION ISOLATION LEVEL
