题目是不难的,就是谁能告诉我为什么我本地的MySQL无论如何都是错的。
加上delimiter $$也并没有什么用...
还有第7行为毛不能加分号或者$$...
1 #drop function getNthHighestSalary$$ 2 CREATE FUNCTION getNthHighestSalary(N INT) RETURNS INT 3 BEGIN 4 DECLARE M INT; 5 SET M = N - 1; 6 RETURN ( 7 select distinct Salary from Employee order by Salary desc limit M, 1 8 ); 9 END
