How do I set SQL isolation levels in database systems?
To set SQL isolation levels, you can use the SET TRANSACTION ISOLATION LEVEL command followed by the desired level.
What are the different isolation levels I can choose from?
The main isolation levels are READ UNCOMMITTED, READ COMMITTED, REPEATABLE READ, and SERIALIZABLE.
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.
How do I choose the right isolation level for my application?
Choosing the right isolation level depends on your application's consistency requirements and performance needs. Higher levels provide more consistency but can reduce performance.
