如何找到重复的工资

Question

我这样做：

SELECT salary COUNT(salary ) AS NumberOfTimes
FROM person
GROUP BY salary   
HAVING (COUNT(salary) > 1) 

Answer 1

除了第一个salary之后缺少的逗号，你所拥有的就好了。你不需要围绕HAVING子句的括号，但我无法想象解析器在乎：

SELECT salary, COUNT(salary) AS NumberOfTimes
FROM person
GROUP BY salary
HAVING COUNT(salary) > 1

Answer 2

在“salary”和“COUNT（salary）”之间添加逗号。
