存储过程误差转换的SQL Server

我想写一个SQL Server存储过程从该查询存储过程误差转换的SQL Server

ALTER procedure [dbo].[sp_get_list_penerimaan_pks] 
    (@tahun int, 
    @bulan int, 
    @pks int)

    declare @query AS NVARCHAR(MAX); 

    SET @cols = STUFF((SELECT distinct ',' + QUOTENAME(c.asal)

       as harga_beli_tbs_bersih 
       FROM

       LEFT JOIN DAILY_GUU AS dg ON CONVERT (datetime, dg.tglolah, 103) = cpo.tanggal 
       LEFT JOIN PNL_TR_HARGA_KOMODITI AS ko ON ko.tanggal = cpo.tanggal 
       WHERE 
       YEAR (cpo.tanggal) >= @tahun and [email protected] and month(cpo.tanggal)[email protected] 
      ) c 
      FOR XML PATH(''), TYPE 
      ).value('.', 'NVARCHAR(MAX)') 
     ,1,1,'') 

    set @query = 'SELECT tanggal, ' + @cols + ' from

       LEFT JOIN DAILY_GUU AS dg ON CONVERT (datetime, dg.tglolah, 103) = cpo.tanggal 
       LEFT JOIN PNL_TR_HARGA_KOMODITI AS ko ON ko.tanggal = cpo.tanggal 
       WHERE 
        YEAR (cpo.tanggal) >= '[email protected] +' and [email protected] and month(cpo.tanggal)[email protected] 
      ) x 
      pivot 
      (
       max(harga_beli_tbs_bersih) 
       for asal in (' + @cols + ') 
      ) p ' 

    execute(@query) 
end

检索转动的结果，但我得到这个错误结果：

我完全对这个错误感到困惑。我已经从谷歌做了一些研究，但仍然无法解决问题。希望你们能帮助我 - 事先感谢。

错误是由于串联整数@tahun变量与字符串。由于INT的优先级高于Varchar，因此该字符串将隐式转换为INT以便发生错误。所以，你需要的@tahun显式转换为varchar

YEAR (cpo.tanggal) >= '+cast(@tahun as varchar(50))+'

你也需要做同样的重命名查询中使用的变量。但是，我会更喜欢使用SP_EXECUTESQL价值传递给变量

SET @query = 'SELECT tanggal, ' + @cols 
      + ' from 
      (
        SELECT 
        cpo.tanggal, 
        dg.asal, 
        (((((cpo - ongkos_ms)* CAST(NULLIF(dg.minyak_efektif,0) as float)/(NULLIF(dg.tbs_diolah, 0))) + ((pko - ongkos_is)* CAST(NULLIF(dg.inti_efektif,0) as float)/(NULLIF(dg.tbs_diolah, 0))))-(447.6 * ((CAST(NULLIF(dg.minyak_efektif,0) as float)/(NULLIF(dg.tbs_diolah, 0)))+(CAST(NULLIF(dg.inti_efektif,0) as float)/(NULLIF(dg.tbs_diolah, 0))))))-(((((cpo - ongkos_ms)* CAST(NULLIF(dg.minyak_efektif,0) as float)/(NULLIF(dg.tbs_diolah, 0))) +((pko - ongkos_is)* CAST(NULLIF(dg.inti_efektif,0) as float)/(NULLIF(dg.tbs_diolah, 0))))-(447.6 * ((CAST(NULLIF(dg.minyak_efektif,0) as float)/(NULLIF(dg.tbs_diolah, 0)))+(CAST(NULLIF(dg.inti_efektif,0) as float)/(NULLIF(dg.tbs_diolah, 0)))))) * 0.02)) 
        as harga_beli_tbs_bersih 
       FROM 
        cpopko cpo 
       LEFT JOIN DAILY_GUU AS dg ON CONVERT (datetime, dg.tglolah, 103) = cpo.tanggal 
       LEFT JOIN PNL_TR_HARGA_KOMODITI AS ko ON ko.tanggal = cpo.tanggal 
       WHERE 
        YEAR (cpo.tanggal) >= @tahun and [email protected] and month(cpo.tanggal)[email protected] 
      ) x 
      pivot 
      (
       max(harga_beli_tbs_bersih) 
       for asal in (' + @cols 
      + ') 
      ) p ' 

EXEC Sp_executesql 
    @query, 
    N'@tahun int,@pks int,@bulan int', 
    @tahun = @tahun, 
    @pks = @pks, 
    @bulan = @bulan

我已经全部投在PARAMS“@查询”字符串为varchar，但没有结果出来。我是否需要在'@cols'中输入参数太先生？执行和Sp_executesql thnks之间的区别是什么be4 sir – Jsnow

@Jsnow - 将参数值传递给静态查询并检查它是否返回任何记录。 'SP_EXECUTESQL'允许您在动态查询中将值传递给变量，以避免SQL注入。你也可以从动态查询结果中获得结果。点击此处查看更多信息https://msdn.microsoft.com/en-us/library/ms188001.aspx –

此旋转表根据上表中的值获取了动态列。从我学会返回的东西我们可以使用函数，但要返回表值，我们必须预定义临时表及其列。我们如何根据查询结果在其列动态的函数中创建一个临时表。先谢谢先生。 – Jsnow
