在网格视图中显示水平和垂直标题与计数 [英] Display headers horizontal and vertical in gridview with count

问题描述

我有一个gridview，它与SQL表链接，我想水平和垂直显示标题，但我卡住了，不知道怎么做。

我想要的结果显示如下，



- 步骤名称---产品1

| - 步骤1 --------- - 2

| --Step2 ----------- 2

| --Step3 ----------- 2

| --Step4 ----------- 2

| --Step5 ----------- 2



上表中的数字是每一步的数量，

i am使用以下SQL代码，

I have a gridview and it is linked with SQL table, i want to display headers horizontally as well as vertically but i am stuck and have no idea how to do it.
I want the result to be displayed as follows,

--StepName---Product1
|--Step1-----------2
|--Step2-----------2
|--Step3-----------2
|--Step4-----------2
|--Step5-----------2

The numbers in above table are count of each step,
i am using the following SQL code,

select 
  sum(case when currentstepname = 'Step1' then 1 else 0 end) Step1,
  sum(case when currentstepname = 'Step2' then 1 else 0 end) Step2,
  sum(case when currentstepname = 'Step3 then 1 else 0 end) Step3,
  sum(case when currentstepname = 'Step4' then 1 else 0 end) Step4,
  sum(case when currentstepname = 'Step5' then 1 else 0 end) Step5

from Table1

我现在得到的结果如下，



- 步骤1 ---步骤2 ---步骤3 ---步骤4 --- Step5

| - 2 --------- 2 -------- 2 -------- 2 ------ -2 ---- |



我的尝试：



搜索网页但没有得到所需的结果。

And i am getting the result currently as follows,

--Step1---Step2---Step3---Step4---Step5
|--2---------2--------2--------2-------2----|

What I have tried:

Searched the web but not getting the required results.

推荐答案

如果我理解你，你必须使用 Pivot [ ^ ]。

If i understand you well, you have to use Pivot[^].

SELECT StepName, [Product1], [Product2], [Product3]
FROM (
    SELECT StepName, ProductName, COUNT(*) AS StepsCount
    FROM Table1
    GROUP BY StepName, ProductName
) AS DT
PIVOT (SUM(StepsCount) FOR (ProductName) IN ([Product1], [Product2], [Product3])) AS PT

试试！
