What are the different isolation levels in SQL?
SQL has four main isolation levels: Read Uncommitted, Read Committed, Repeatable Read, and Serializable.
Can you explain what Read Uncommitted means?
Read Uncommitted allows transactions to read data that has been modified but not yet committed, leading to dirty reads.
What about Serializable? How does it work?
Serializable is the strictest isolation level, ensuring complete isolation by preventing other transactions from accessing data until the current transaction is complete.
