我有一個動態的支點寫成下面,我需要添加一個where
條款動態支點where子句
DECLARE @cols AS NVARCHAR(MAX),
@query AS NVARCHAR(MAX),@uniqId varchar(50);
set @uniqId = 'IN0s3Z0n8z4v'
select @cols = STUFF((SELECT distinct ',' + QUOTENAME(c.DisplayLabel)
FROM [dbo].[CountyCaseUserData] c where UniqueEntryId = @uniqId
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
print @cols
set @query = 'SELECT ' + @cols + '
from
(
SELECT UserInput, DisplayLabel,row_number()
over (partition by DisplayLabel order by CCId) AS No
from [dbo].[CountyCaseUserData] where UniqueEntryId = @uniqId
) x
pivot
(
max(UserInput)
for DisplayLabel in (' + @cols + ')
) p ';
execute(@query)
但在執行的時候,我得到一個消息
必須聲明標量變量「 @uniqId「
我在這裏錯過了什麼?
首先聲明'@ uniqid'然後是'這裏UniqueEntryId = '' '+ @uniqId + ''') x'或使用'sp_executesql'作爲參數傳遞。 –
執行不知道變量。所以你需要將它添加到Les H建議的@query中。 – LukStorms
