Question

我正在尝试编写一个存储过程，它将SQL查询的结果转换为HTML字符串，并将其显示在HTML表格中。

我遇到的问题是我使用FOR XML获取逗号分隔的td值列表，然后尝试连接它，但是当我这样做时，它会丢失<和{{ 1}}字符并将其替换为XML >和&lt - 我需要它将其显示为&gt。

这是执行此操作的查询部分：

<>

然而，这就是它的回报：

    declare C cursor for
    select (convert(nvarchar(max),(SELECT "th/@width"='50', th = name
    FROM tempdb.sys.columns isc
    WHERE object_id = OBJECT_ID('tempdb.dbo.##tempcolumns') 
            for xml PATH(N''), TYPE)))
    open C
    declare @L varchar(max)
    fetch next from C into @L
    close C
    deallocate C

    DECLARE @html nvarchar(max), @table nvarchar(max), @test nvarchar(max), @html2 nvarchar(max) 
    SET @html =  
    N'<html> <head><title>TestHTML</title></head>' + CHAR(10) + 
    N'<body style="font-family: Arial;">' + 
    N'<h1>Companies2</h1></font>' + 
    '<table style="float: left; width:100%;">' + 
    N'<tr>' + 
            @L +
    N'</tr>' + CHAR(10); 

    SELECT @table = CONVERT(nvarchar(max),(SELECT (
    SELECT  '<td>' + STUFF( ( SELECT td = ', '  + '[' + isc.name + ']' 
    FROM tempdb.sys.columns isc
    WHERE isc.object_id = OBJECT_ID('tempdb.dbo.##tempcolumns') FOR XML PATH ('')), 1,5,'')) FROM ##temp FOR XML PATH(''), TYPE))


    SET @html = @html + @table + CHAR(10) +  
                N'</table></body></html>' 

    SELECT @table

如何让它显示为<td> [Reasons_Code]</td><td>, [Open]</td><td>, [Ordered]</td><td>, [Partially Ordered]</td><td>, [Lost]</td><td>, [Not Pursued]</td><td>, [Expired (Past 90 days)]</td><td>, [Pending]</td><td> [Reasons_Code]</td><td>, [Open]</td><td>, [Ordered]</td><td>, [Partially Ordered]</td><td>, [Lost]</td><td>, [Not Pursued]</td><td>, [Expired (Past 90 days)]</td><td>, [Pending]</td><td> [Reasons_Code]</td><td>, [Open]</td><td>, [Ordered]</td><td>, [Partially Ordered]</td><td>, [Lost]</td><td>, [Not Pursued]</td><td>, [Expired (Past 90 days)]</td><td>, [Pending]</td><td> [Reasons_Code]</td><td>, [Open]</td><td>, [Ordered]</td><td>, [Partially Ordered]</td><td>, [Lost]</td><td>, [Not Pursued]</td><td>, [Expired (Past 90 days)]</td><td>, [Pending]</td><td> [Reasons_Code]</td><td>, [Open]</td><td>, [Ordered]</td><td>, [Partially Ordered]</td><td>, [Lost]</td><td>, [Not Pursued]</td><td>, [Expired (Past 90 days)]</td><td>, [Pending]</td><td> [Reasons_Code]</td><td>, [Open]</td><td>, [Ordered]</td><td>, [Partially Ordered]</td><td>, [Lost]</td><td>, [Not Pursued]</td><td>, [Expired (Past 90 days)]</td><td>, [Pending]</td><td> [Reasons_Code]</td><td>, [Open]</td><td>, [Ordered]</td><td>, [Partially Ordered]</td><td>, [Lost]</td><td>, [Not Pursued]</td><td>, [Expired (Past 90 days)]</td><td>, [Pending]</td><td> [Reasons_Code]</td><td>, [Open]</td><td>, [Ordered]</td><td>, [Partially Ordered]</td><td>, [Lost]</td><td>, [Not Pursued]</td><td>, [Expired (Past 90 days)]</td><td>, [Pending]</td>而不是<td> [Reasons_Code] </td>

通过堆叠for xml语句，您告诉SQL Server您要保留XML字符串中包含保留XML字符的值，例如：

<ActualTag>Your values that contain a < and > special character</ActualTag>

这显然是不可能的。仅仅因为您使用技巧来删除原本存在的标记，您仍然在处理XML 值。

要么改变你的字符串构建方法，要么改变select最终XML变量中的value：

declare @x xml = '<ActualTag>Your values that contain a &lt; and &gt; special character</ActualTag>';
select @x.value('.','nvarchar(max)')

输出：

Your values that contain a < and > special character

使用for xml＆lt;连接的html逗号连接＆LT;
