How can I handle database concurrency issues in my application?
An example of an AI chatbot conversation about handling database concurrency in applications.
How can I handle database concurrency issues in my application?
Handling database concurrency involves strategies like locking, transactions, and isolation levels. What specific issues are you facing?
I'm worried about lost updates when multiple users edit the same record.
You can use optimistic concurrency control, where you check if the record has changed before saving. Would you like to know how to implement that?
Yes, please explain how to implement optimistic concurrency control.
You can add a version number or timestamp to your records. When updating, check if the version matches the one you retrieved. If it doesn't, it means another user has updated it.
What if I want to prevent users from editing the same record at the same time?
In that case, you can use pessimistic locking, which locks the record for editing until the transaction is complete.
