How to Fix: UPDATE multiple rows with different values in one query in MySQL

Update multiple rows with different values in one MySQL query.

Quick Answer: Use the `UPDATE` statement with a `SET` clause and multiple conditions, separated by commas. For example: `UPDATE table_users SET cod_user = '622057', date = '12082014' WHERE user_rol = 'student' AND cod_office = '17389551'; UPDATE table_users SET cod_user = '2913659', date = '12082014' WHERE user_rol = 'assistant' AND cod_office = '17389551'; UPDATE table_users SET cod_user = '6160230', date = '12082014' WHERE user_rol = 'admin' AND cod_office = '17389551';`
