选择Count（*）大于数字的值

Question

我是使用SQL Server和数据库的新手 - 这可能非常简单。

我正在尝试为JobTitle和Count(*)返回仅Count(*)超过9的值的值。我还尝试测试了一些子查询但无法使其工作。

Use AdventureWorks2014;

Select 
    JobTitle, Count(*) as Number
From 
    HumanResources.Employee
Where 
    Number > 9
Group By 
    JobTitle; 

Answer 1

将逻辑从WHERE子句移到HAVING子句中：

Select JobTitle, COUNT(*) AS Number
FROM HumanResources.Employee
GROUP BY JobTitle
HAVING COUNT(*) > 9
ORDER BY COUNT(*);   -- or ORDER BY Number
