Question

我正在使用存储过程并将其与ASP C＃链接，以下查询成功运行且没有错误：

SELECT       loginInfo.ApplicantID, Personal.FirstName, Personal.LastName, Personal.Nationality, Job.PositionType, 
                      Job.InterestedArea, loginInfo.ApplicantStatus, Latest.HighestDegree, Latest.CompletionDate, 
                      Latest.LatestJobTitle, Latest.LatestCompanyIndustry, Latest.StartDate, Latest.EndDate,
                      SUM(DATEDIFF(YEAR,Exper.StartDate,Exper.EndDate)) AS TotalYearsExp
FROM         dbo.ApplicantLoginInfo AS loginInfo INNER JOIN
                      dbo.PersonalInfo AS Personal ON loginInfo.ApplicantID = Personal.ApplicantID INNER JOIN
                      dbo.InterestedJob AS Job ON loginInfo.ApplicantID = Job.ApplicantID INNER JOIN
                      dbo.LatestAcadExpInfo AS Latest ON loginInfo.ApplicantID = Latest.ApplicantID INNER JOIN
                      dbo.Experience AS Exper ON loginInfo.ApplicantID = Exper.ApplicantID

WHERE 1=1


GROUP BY loginInfo.ApplicantID, Personal.FirstName, Personal.LastName, Personal.Nationality, Job.PositionType, 
                      Job.InterestedArea, loginInfo.ApplicantStatus, Latest.HighestDegree, Latest.CompletionDate, 
                      Latest.LatestJobTitle, Latest.LatestCompanyIndustry, Latest.StartDate, Latest.EndDate

ORDER BY ApplicantID DESC

现在我需要在子句中添加DYNAMIC，所以我将查询分为3个部分@ SQL，@ WHERE，@ GROUPBY。

请注意，我有一个总函数和。

    if @gender <> '' SET @WHERE = ' AND Gender='''+@gender+''''
    if @nationality <> '' SET @WHERE = @WHERE + ' AND Nationality='''+@nationality+''''
    if @highestdegree <> '' SET @WHERE = @WHERE + ' AND HighestDegree='''+@highestdegree+''''
    if @latestcompanyindustry <> '' SET @WHERE = @WHERE + ' AND LatestCompanyIndustry='''+@latestcompanyindustry+''''
    if @interestedarea <> '' SET @WHERE = @WHERE + ' AND InterestedArea='''+@interestedarea+''''

    SET @SQL = 'SELECT loginInfo.ApplicantID, Personal.FirstName, Personal.LastName, Personal.Nationality, Job.PositionType,
    Job.InterestedArea, loginInfo.ApplicantStatus, Latest.HighestDegree, Latest.CompletionDate, Latest.LatestJobTitle, Latest.LatestCompanyIndustry, Latest.StartDate, Latest.EndDate,
    SUM(DATEDIFF(YEAR,Exper.StartDate,Exper.EndDate)) AS TotalYearsExp
    FROM dbo.ApplicantLoginInfo AS loginInfo INNER JOIN dbo.PersonalInfo AS Personal ON loginInfo.ApplicantID = Personal.ApplicantID INNER JOIN
    dbo.InterestedJob AS Job ON loginInfo.ApplicantID = Job.ApplicantID INNER JOIN 
dbo.LatestAcadExpInfo AS Latest ON loginInfo.ApplicantID = Latest.ApplicantID INNER JOIN dbo.Experience AS Exper ON loginInfo.ApplicantID = Exper.ApplicantID
    WHERE 1=1'

    SET @GROUPBY = 'GROUP BY loginInfo.ApplicantID, Personal.FirstName, Personal.LastName, Personal.Nationality, Job.PositionType, 
                                  Job.InterestedArea, loginInfo.ApplicantStatus, Latest.HighestDegree, Latest.CompletionDate, 
                                  Latest.LatestJobTitle, Latest.LatestCompanyIndustry, Latest.StartDate, Latest.EndDate

            ORDER BY ApplicantID DESC'

            EXEC(@SQL+@WHERE+@GROUPBY)

我一直收到错误

Error: The multi-part identifier "dbo.LatestAcadExpInf" could not be bound. The multi-part identifier "dbo.Experience.StartDate" could not be bound. The multi-part identifier "dbo.Experience.EndDate" could not be bound

Answer 1

很奇怪，我所要做的就是将列放在[] ..

中
