Sql server 按分组的TSQL计数行

我需要分组后的行数

SELECT COUNT(CheckNumber)
FROM myTable
WHERE Status = 'Good'
GROUP BY CheckNumber

结果:

Row 1 = 1
Row 2 = 15
Row 3 = 5

Row 1 = 1
Row 2 = 1
Row 3 = 1

我还试着使用DISTINCT

SELECT COUNT(DISTINCT CheckNumber)
FROM myTable
WHERE Status = 'Good'
GROUP BY CheckNumber

结果:

Row 1 = 1
Row 2 = 15
Row 3 = 5

Row 1 = 1
Row 2 = 1
Row 3 = 1

---

我希望结果为3

如果我理解正确，您可以这样做：

SELECT COUNT(*) FROM
(
   SELECT COUNT(CheckNumber)
   FROM myTable
   WHERE Status = 'Good'
   GROUP BY CheckNumber
) as myData

根据您的要求，这将为您提供总共3个。

在我看来，根据您所说的您想要的，分组方式是完全多余的。为什么不只是：

SELECT COUNT(distinct CheckNumber) 
FROM myTable
WHERE Status = 'Good'

您能提供“myTable”上的数据吗？为什么您希望结果是3？计数本身告诉您什么，并且没有标识符？
