Question

我一直盯着这看太久了，我似乎无法看到我哪里出错了我有一个存储过程，必须返回一堆数据，其中“ExtractedText”匹配该人正在搜索的单词

Select @Command = 'select DISTINCT CaseFileEvents.InvestigatorID,convert(nvarchar,EventDate,111) as ''EventDate'',EventTime,EventDesc,TaskID,Privileged,Private,Email,HasAttachments,FName,LName, FName + '' '' + LName as Name ,CaseFileEvents.FileID,CaseFiles.FileName,ItemEntryGradeID, EventDescPlainText
                from CaseFileEvents
                join ......

                WHERE '+ @FilterField +' LIKE ''%' + @FilterQuery + '%'' ORDER BY ' + @SortName + ' ' + @SortOrder + ''; this area seems to bug out

@FilterField是其中一个表中的一列，@ FilterQuery是用户输入的单词，它正在寻找。 @SortName，是它被排序的名称。

EDIT-命令示例：@FilterField =“ExtractedText”，@ FilterQuery =“something”，@ SortName =“EventID”，@ SortOrder =“desc”

这是错误：Msg 156, Level 15, State 1, Line 10 Incorrect syntax near the keyword 'ORDER'.

完整命令：WHERE ExtractedText LIKE '%add%' ORDER BY EventID desc;

您无法按变量排序。您需要使用动态sql：

SELECT
     *
FROM
     My_Table
WHERE
     Whatever = @something
ORDER BY
     CASE @sort_order
          WHEN 'ASC' THEN
               CASE @order_by
                    WHEN 'surname' THEN surname
                    WHEN 'forename' THEN forename
                    WHEN 'fullname' THEN fullname
                    ELSE surname
               END
          ELSE '1'
     END ASC,
     CASE @sort_order
          WHEN 'DESC' THEN
               CASE @order_by
                    WHEN 'surname' THEN surname
                    WHEN 'forename' THEN forename
                    WHEN 'fullname' THEN fullname
                    ELSE surname
               END
          ELSE '1'
     END DESC

Answer 2

它不起作用的原因是因为我失踪了 WHERE EventID = convert(nvarcahr,@EventID) 然后拿出“DISTINCT”

“Order By”附近的语法错误
