How do I set the isolation level in SQL?

You can set the isolation level in SQL using the SET TRANSACTION ISOLATION LEVEL statement. What level do you want to set?

I want to set it to SERIALIZABLE.

To set the isolation level to SERIALIZABLE, you would use: SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;. This ensures complete isolation.

What are the different isolation levels available?

The main isolation levels are READ UNCOMMITTED, READ COMMITTED, REPEATABLE READ, and SERIALIZABLE. Each has different behaviors regarding data visibility.

Can you explain the differences between these levels?

Sure! READ UNCOMMITTED allows dirty reads, READ COMMITTED prevents dirty reads, REPEATABLE READ prevents non-repeatable reads, and SERIALIZABLE prevents phantom reads.
