How do I update records in SQL?

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

Can you give me an example of updating multiple columns?

Sure! You can update multiple columns like this: UPDATE table_name SET column1 = value1, column2 = value2 WHERE condition;

What if I want to update all records?

If you want to update all records, you can omit the WHERE clause: UPDATE table_name SET column1 = value1; Be careful, as this will change all rows!

How do I check if the update was successful?

You can use the SELECT statement to verify the changes: SELECT * FROM table_name WHERE condition; This will show you the updated records.
