我的表包含如下聚合数据：
Name | Data | Status | Count
----------------------------------
A | 2017-06-01 | ok | 2
A | 2017-06-01 | error | 5
A | 2017-06-02 | ok | 3
A | 2017-06-02 | error | 1
A | 2017-06-03 | ok | 5
B | 2017-06-01 | ok | 1
B | 2017-06-01 | error | 7
B | 2017-06-02 | ok | 3
B | 2017-06-02 | error | 3
B | 2017-06-03 | error | 2
现在我正在尝试使用名称作为列创建数据透视表，将日期作为行创建。在单元格内部，我想获得状态为{1}}
错误状态的行数为ok的数字或行数以下是我想要的表格：
2/5因为我在Data | A | B
------------------------
2017-06-01 | 2/5 | 1/7
2017-06-02 | 3/1 | 3/3
2017-06-03 | 5/- | -/2
列中可以有不同的值，所以我创建了动态查询来获取这些值。
我的代码如下所示：
Name但是我获得了两次行（可能是因为我没有按状态分组）。
如何获得我需要的结果？
我在sqlfiddle中构建了示例：http://sqlfiddle.com/#!6/31770/3

您可以在旋转之前计算TotalOk / TotalError
CREATE TABLE TMP

INSERT INTO TMP

首先，你在B的小提琴中写错了数据（所以也许你看不到部分预期的结果）。 我想你可以尝试这样的事情（我只是改变了一下最后一个查询，在一个字符串中聚合'ok'和'error'：
DECLARE @DynamicPivotQuery AS NVARCHAR(MAX)
DECLARE @ColumnName AS NVARCHAR(MAX)
SELECT
@ColumnName = ISNULL(@ColumnName + ',', '') + QUOTENAME(Name)
FROM
( SELECT DISTINCT
Name
FROM
TMP
) AS Courses
SET @DynamicPivotQuery ='
SELECT * FROM
(SELECT Data, NAME, MAX(CASE WHEN STATUS=''ok'' THEN CAST(COUNT AS VARCHAR(8))
ELSE ''-'' END) +''/''
+ MAX(CASE WHEN STATUS=''error'' THEN CAST(COUNT AS VARCHAR(8)) ELSE ''-'' END) AS C
FROM TMP
GROUP BY DATA, NAME) X
PIVOT ( MAX(C) FOR Name IN (' + @ColumnName + ')) AS PVTTable'
EXEC sp_executesql @DynamicPivotQuery
输出：
Data A B
2017-06-01 2/5 1/7
2017-06-02 3/1 3/3
2017-06-03 5/- -/2
更新版本：
SET @DynamicPivotQuery ='
SELECT *
FROM (SELECT Y.DATA, Y.NAME, MAX(CASE WHEN STATUS=''ok'' THEN CAST(COUNT AS VARCHAR(8)) ELSE ''-'' END) +''/''
+ MAX(CASE WHEN STATUS=''error'' THEN CAST(COUNT AS VARCHAR(8)) ELSE ''-'' END) AS C
FROM TMP
RIGHT JOIN (SELECT DISTINCT TMP.NAME, Z.DATA
FROM TMP CROSS JOIN (SELECT DISTINCT DATA FROM TMP ) Z) Y ON TMP.NAME = Y.NAME AND TMP.DATA = Y.DATA
GROUP BY Y.DATA, Y.NAME) X
PIVOT ( MAX(C) FOR Name IN (' + @ColumnName + ')) AS PVTTable'
