这返回了两条记录.我不知道第二高薪水有多少条记录.
This return two record.I do not know how many record in second highest salary.
答
SELECT sal
FROM emp
ORDER BY sal DESC
LIMIT 1, 1;
你只会得到第二个最高工资.
You will get only the second max salary.
如果您需要任何第 3 个或第 4 个或第 N 个值，您可以增加第一个值，然后是 LIMIT (n-1) 即.第四薪:LIMIT 3, 1;
And if you need any 3rd or 4th or Nth value you can increase the first value followed by LIMIT (n-1) ie. for 4th salary: LIMIT 3, 1;
