mysql从大到小排序

要实现MySQL中的从大到小排序，可以使用关键字DESC（descend）。在ORDER BY子句中，将DESC关键字添加到要排序的列后面即可。例如，以下是一个示例查询语句：

SELECT employee_id, last_name, salary
FROM employees
ORDER BY salary DESC;

这将按照salary列的值从大到小对结果进行排序。\[1\]另外，也可以使用列的别名来进行排序。通过给列起一个别名，可以在ORDER BY子句中使用别名来进行排序操作。例如：

SELECT employee_id, last_name, salary, salary * 12 AS annual_salary
FROM employees
ORDER BY annual_salary DESC;

这将按照计算出的年薪（即salary * 12）的值从大到小对结果进行排序。\[3\]
