To update multiple rows in MySQL, you can use the UPDATE statement with a WHERE clause that specifies the condition for the rows you want to update. Here is an example:

UPDATE table_name SET column1 = value1, column2 = value2 WHERE condition;

In this statement, table_name is the name of the table containing the rows you want to update. column1 and column2 are the names of the columns you want to update, and value1 and value2 are the new values you want to set for those columns. condition is the WHERE clause that specifies which rows you want to update.

For example, if you have a table named customers with columns named first_name, last_name, and email, and you want to update the email address for all customers with the last name “Smith”, you could use the following SQL statement:

UPDATE customers SET email = '' WHERE last_name = 'Smith';

This would update the email column for all rows in the customers table where the last_name is equal to “Smith”, setting the email address to ““.
