Sql 如何根据列的唯一值对列进行分组，并根据其值将计数放入不同的列？

我有一个分类表，如下所示

我想根据

scStatus

value及其计数组通过

catID

catID | 0 | 2 | 3
----- |---|---|---
 2    | 1 | 0 | 1
 3    | 1 | 1 | 0
 4    | 2 | 0 | 1
 5    | 0 | 1 | 0

我试过这样做，

选择catID，按catID从tableName组中将（scStatus）计数为[count]，按catID将scStatus排序，但我无法进入该值的列

`使用数据透视查询：

SELECT catID,
       SUM(CASE WHEN scStatus = 0 THEN 1 ELSE 0 END) AS [0],
       SUM(CASE WHEN scStatus = 2 THEN 1 ELSE 0 END) AS [2],
       SUM(CASE WHEN scStatus = 3 THEN 1 ELSE 0 END) AS [3]
FROM Category
GROUP BY catID

使用透视查询：

SELECT catID,
       SUM(CASE WHEN scStatus = 0 THEN 1 ELSE 0 END) AS [0],
       SUM(CASE WHEN scStatus = 2 THEN 1 ELSE 0 END) AS [2],
       SUM(CASE WHEN scStatus = 3 THEN 1 ELSE 0 END) AS [3]
FROM Category
GROUP BY catID

select      *
from        (select catID,scStatusvalue from t) t
                pivot (count(scStatusvalue) for scStatusvalue in ([0],[2],[3])) t

select      *
from        (select catID,scStatusvalue from t) t
                pivot (count(scStatusvalue) for scStatusvalue in ([0],[2],[3])) t
