我想找出有多少个包含字符串 01 的计划代码，但我就是不知道如何在列中添加数字。

这是我想出的代码：

SELECT [Plan Code], COUNT(*) AS 'How Many' 
FROM Raw 
WHERE [Plan Code] LIKE '%01%' 
GROUP BY [Plan Code];

它输出

计划代码	有多少
010JR	1
010QA	1
010VA	1
D01DE	10
D01VA	5

剩下要做的就是添加列中的数字（总计为 18），但我无法将其转换为代码。关于如何继续有什么想法吗？

Answer 1

只需从查询中删除 GROUP BY 子句和 [计划代码] 列即可。有用。在我的机器上测试过。

SELECT COUNT(*) AS 'How Many' 
FROM Raw 
WHERE [Plan Code] LIKE '%01%' 

谢谢你。
