How do I use SQL UPDATE queries?
SQL UPDATE queries are used to modify existing records in a table. You specify the table and the new values.
Can you give me an example of an UPDATE query?
Sure! Here's a basic example: UPDATE employees SET salary = 50000 WHERE id = 1;
This updates the salary of the employee with id 1.
What if I want to update multiple columns?
You can update multiple columns by separating them with commas. For example: UPDATE employees SET salary = 50000, position = 'Manager' WHERE id = 1;
Are there any risks when using UPDATE queries?
Yes, if you don't specify a WHERE clause, all records in the table will be updated. Always back up your data!
