[英]Dynamic SQL Server Pivot Table
I found a nice script that dynamically creates by column names for my pivot table, but I am not getting the assigned values back into the table. 我发现了一个很好的脚本,它可以通过我的数据透视表的列名动态创建,但是我没有将指定的值重新放回到表中。 Here is my starting table. 这是我的起始桌。
ORDER_ID DSC_NAME NAME
----------- --------------- -----------
2 34-1500-XXX DWG_DOC
3 C0403 EQIP_1
4 C4054 EQIP_2
1 34-1500-013 PART
0 88-0000 PRCS
I run this SQL to generate my columns that I want in my pivot table 我运行此SQL以在我的数据透视表中生成我想要的列
DECLARE @cols AS NVARCHAR(MAX), @query AS NVARCHAR(MAX);
select @cols = STUFF((SELECT distinct
',' + QUOTENAME(NAME)
FROM test
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
This gives me the following output 这给了我以下输出
[DWG_DOC],[EQIP_1],[EQIP_2],[PART],[PRCS]
When I run the dynamic SQL for the Pivot Table 当我为数据透视表运行动态SQL时
SET @query = 'SELECT ' + @cols + ' from
(
SELECT ORDER_ID,DSC_NAME
FROM test
) x
pivot
(
MIN(ORDER_ID)
for DSC_NAME in (' + @cols + ')
) p '
execute(@query)
I see this result... 我看到这个结果......
DWG_DOC EQIP_1 EQIP_2 PART PRCS
----------- ----------- ----------- ----------- -----------
NULL NULL NULL NULL NULL
I have tried several different options, but I not come up with a solution to why this is not working. 我已经尝试了几种不同的选择,但我没有想出解决方案,为什么这不起作用。
Desired Output would be where the column order is correct by the ORDER_ID 期望的输出将是ORDER_ID的列顺序正确的位置
PRCS PART DWG_DOC EQIP_1 EQIP_2
---------- -------------- -------------- --------- ---------
88-0000 34-1500-013 34-1500-XXX C0403 C4054
But this would also work my application as well. 但这也适用于我的应用程序。
DWG_DOC EQIP_1 EQIP_2 PART PRCS
-------------- --------- --------- -------------- -----------
34-1500-XXX C0403 C4054 34-1500-013 88-0000
Remove the ORDER_ID
from the selection, and select the column name
: 从选择中删除ORDER_ID
,然后选择列name
:
SET @query = 'SELECT ' + @cols + ' from
(
SELECT ORDER_ID, DSC_NAME -- <--- you didn't select the name here
FROM test
) x
pivot
(
MIN(ORDER_ID)
for DSC_NAME in (' + @cols + ')
) p '
And use MAX(DSC_Name)
instead of MIN(ORDER_ID)
. 并使用MAX(DSC_Name)
代替MIN(ORDER_ID)
。 Like this: 像这样:
SET @query = 'SELECT '+ @cols + ' from
(
SELECT DSC_NAME, Name
FROM test
) x
pivot
(
MAX(DSC_Name)
for NAME in (' + @cols + ')
) p ';
This will give you: 这会给你:
| DWG_DOC | EQIP_1 | EQIP_2 | PART | PRCS |
---------------------------------------------------------
| 34-1500-XXX | C0403 | C4054 | 34-1500-013 | 88-0000 |
