SQL替換函數不起作用

Question

我在寫下面的SQL查詢來替換雙重空間。但它給錯誤。誰能幫忙？

下面的代碼： -

Select * 
From (
    select nvcFormName,iEvalID,iFormID,dtCreationTime,dtEvaluatedStartTime, 
     fltGradScore,nvcFormattedName,iEvaluatorUserID, 
     iAgentUserID,flScore,iQuestionID,nvcQuestionAnswer 
    from dbo.vwEvaluationQuestions 
    inner join dbo.vwUser on iUserId = iAgentUserID where iFormID = 160 
) as s 
Pivot (min(nvcQuestionAnswer) for iQuestionID in ([23732], replace([23742],' ','')) as pvt 
where dtEvaluatedStartTime > '2017-04-01' and dtEvaluatedStartTime < '2017-04-30' 
order by dtEvaluatedStartTime asc 

Answer 1

替換功能用於字符串的字符替換。使用此代替。單引號會做

REPLACE（ '[23742]'， ''， ''）

SELECT * 
FROM (
    SELECT nvcFormName 
     ,iEvalID 
     ,iFormID 
     ,dtCreationTime 
     ,dtEvaluatedStartTime 
     ,fltGradScore 
     ,nvcFormattedName 
     ,iEvaluatorUserID 
     ,iAgentUserID 
     ,flScore 
     ,iQuestionID 
     ,nvcQuestionAnswer 
    FROM dbo.vwEvaluationQuestions 
    INNER JOIN dbo.vwUser 
     ON iUserId = iAgentUserID 
    WHERE iFormID = 160 
    ) AS s 
Pivot(min(nvcQuestionAnswer) FOR iQuestionID IN (
      [23732] 
      ,replace('[23742]', ' ', '') 
      ) AS pvt WHERE dtEvaluatedStartTime > '2017-04-01' 
     AND dtEvaluatedStartTime < '2017-04-30' ORDER BY dtEvaluatedStartTime)
