An example of an AI chatbot conversation about preventing lost updates in SQL.
How can I prevent lost updates in SQL?
To prevent lost updates in SQL, you can use techniques like optimistic concurrency control or locking mechanisms.
What is optimistic concurrency control?
Optimistic concurrency control allows multiple transactions to proceed without locking resources, checking for conflicts before committing.
Are there any specific SQL commands I should use?
Yes, you can use the SELECT ... FOR UPDATE command to lock rows during a transaction, preventing other transactions from modifying them.
What are the downsides of using locks?
Using locks can lead to decreased performance and potential deadlocks if not managed properly, especially in high-concurrency environments.
