What is database isolation level?
An example of an AI chatbot conversation about database isolation levels in SQL.
What is database isolation level?
Database isolation level defines how transaction integrity is visible to other transactions. It controls the visibility of changes made by one transaction to others.
What are the different types of isolation levels?
The main isolation levels are Read Uncommitted, Read Committed, Repeatable Read, and Serializable. Each level offers a different balance between performance and data integrity.
Can you explain Read Committed in detail?
Read Committed ensures that any data read is committed at the moment it is read. This prevents dirty reads but allows non-repeatable reads.
What are the trade-offs of using Serializable?
Serializable is the strictest isolation level, preventing phantom reads but can lead to decreased performance due to increased locking.
