How do I set the default isolation level in SQL?
To set the default isolation level in SQL, you can use the command: SET TRANSACTION ISOLATION LEVEL <level>;
Replace <level>
with your desired isolation level, such as READ COMMITTED or SERIALIZABLE.
What are the different isolation levels I can choose from?
The main isolation levels are: READ UNCOMMITTED, READ COMMITTED, REPEATABLE READ, and SERIALIZABLE. Each level offers a different balance between consistency and performance.
Can I set the isolation level for a specific session?
Yes, you can set the isolation level for a specific session by executing the SET TRANSACTION ISOLATION LEVEL
command within that session. It won't affect other sessions.
What happens if I don't set an isolation level?
If you don't set an isolation level, SQL will use the default isolation level defined by the database system, which is often READ COMMITTED.
