SQL Server：从上载文件更新的存储过程无法正常工作

Question

帮助我们，我正在创建一个存储过程，我可以从上传的文件中更新现有表中的一些表行，但是我在更新开始的部分遇到了麻烦。

• @sourceTable =表名
• #temp1 =已上传的文件

代码：

BEGIN
    set @refnum = (select refnum from #records where [index] = @index)
    set @refnum = replace(@refnum, 'F', '')

    --  = '+@refnum+'(courier, stat, statdate, stat2, statdate2, stat3, statdate3, recvby, rel, pupdate)

    set @sql = '
        UPDATE ' + @sourceTable + '
        SET ' + @sourceTable + '.courier =  t2.dbo.fn_Parsename(WHOLEROW,''|'', 1),
        '+@sourceTable+'.stat =  t2.dbo.fn_Parsename(WHOLEROW,''|'',3), 
        '+@sourceTable+'.statdate =  t2.dbo.fn_Parsename(WHOLEROW,''|'',4),
        '+@sourceTable+'.stat2 =  t2.dbo.fn_Parsename(WHOLEROW,''|'',5), 
        '+@sourceTable+'.statdate2 =  t2.dbo.fn_Parsename(WHOLEROW,''|'',6),
        '+@sourceTable+'.stat3 =  t2.dbo.fn_Parsename(WHOLEROW,''|'',7),
        '+@sourceTable+'.statdate3 =  t2.dbo.fn_Parsename(WHOLEROW,''|'',8),
        '+@sourceTable+'.recvby =  t2.dbo.fn_Parsename(WHOLEROW,''|'',9),
        '+@sourceTable+'.rel =  t2.dbo.fn_Parsename(WHOLEROW,''|'',10),
        '+@sourceTable+'.pupdate =  t2.dbo.fn_Parsename(WHOLEROW,''|'',11),
        FROM baseTable '+@sourceTable+' 

        INNER JOIN tempTable #temp1 ON baseTable.refdate + baseTable.refdate = tempTable.dbo.fn_Parsename(WHOLEROW,''|'',0)

        WHERE baseTable.refdate + baseTable.refdate = tempTable.dbo.fn_Parsename(WHOLEROW,''|'',0)

        SELECT
            dbo.fn_Parsename(WHOLEROW,''|'',1),
            dbo.fn_Parsename(WHOLEROW,''|'',3),
            dbo.fn_Parsename(WHOLEROW,''|'',4),
            dbo.fn_Parsename(WHOLEROW,''|'',5), 
            dbo.fn_Parsename(WHOLEROW,''|'',6),
            dbo.fn_Parsename(WHOLEROW,''|'',7),
            dbo.fn_Parsename(WHOLEROW,''|'',8),
            dbo.fn_Parsename(WHOLEROW,''|'',9), 
            dbo.fn_Parsename(WHOLEROW,''|'',10),
            dbo.fn_Parsename(WHOLEROW,''|'',11)
            '
            select @sql
            print @sql
            --exec (@sql)

        SELECT 'File has been successfully uploaded', @fileDate,'success' as msg

        set @index = @index + 1
   END
