How do I update data in SQL?

To update data in SQL, you can use the UPDATE statement. For example: UPDATE table_name SET column1 = value1 WHERE condition;

Can you give me an example with a specific table?

Sure! If you have a table called 'Employees' and you want to update the salary of an employee with ID 1, you would write: UPDATE Employees SET salary = 60000 WHERE 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 = 60000, position = 'Manager' WHERE id = 1;

Are there any risks I should be aware of when updating data?

Yes, always ensure you have a WHERE clause to avoid updating all rows unintentionally. It's also good to back up your data.
