An example of an AI chatbot conversation about setting transaction isolation levels in a database.
How do I set transaction isolation levels in a database?
To set transaction isolation levels, you can use SQL commands like SET TRANSACTION ISOLATION LEVEL. What database are you using?
I'm using PostgreSQL. Can you give me an example?
Sure! In PostgreSQL, you can set the isolation level with: SET TRANSACTION ISOLATION LEVEL SERIALIZABLE; This sets the highest level of isolation.
What are the different isolation levels available?
The main isolation levels are READ UNCOMMITTED, READ COMMITTED, REPEATABLE READ, and SERIALIZABLE. Each has different trade-offs.
How do these levels affect performance?
Higher isolation levels like SERIALIZABLE can lead to more locking and reduced concurrency, impacting performance. It's a balance!
