How does locking work in SQL?
An example of an AI chatbot conversation about SQL locking mechanisms.
Can you explain how locking works in SQL?
Sure! Locking in SQL is a mechanism to control access to data in a database to ensure consistency.
What are the different types of locks in SQL?
There are mainly two types of locks: shared locks and exclusive locks. Shared locks allow multiple transactions to read data, while exclusive locks prevent others from accessing the data.
How do locks affect database performance?
Locks can impact performance by causing delays if multiple transactions are trying to access the same data. Proper management is essential.
Can you give an example of a locking scenario?
Certainly! For instance, if Transaction A locks a row for updating, Transaction B must wait until Transaction A releases the lock before it can read or modify that row.
