c# - 当 Microsoft SQL Server 中包含 html 标签时对列进行排序

Question

我的 SQL Server 数据库中有几列，如下所示:

Column1                       Column2   
Item1                         <div id="html"><img.............>5424</div>
Item2                         <div id="html"><img.............>3424</div>
Item3                         <div id="html"><img.............>8424</div>
Item4                         <div id="html"><img.............>6424</div>

我想根据 >*</div> 内部的值使用 ORDER BY 对它们重新排序，这样输出看起来像这样:

Column1                       Column2   
Item2                         <div id="html"><img.............>3424</div>
Item1                         <div id="html"><img.............>5424</div>
Item4                         <div id="html"><img.............>6424</div>
Item3                         <div id="html"><img.............>8424</div>

我使用以下代码从数据库中提取值:

SELECT 
    Table1_1.F1 AS Column1, Table2_1.1PrisHTML AS Column2
FROM     
    Table2 AS Table2_1 
CROSS JOIN
    Table1 AS Table1_1

UNION ALL

SELECT 
    Table1_1.L1, Table2_1.2PrisHTML
FROM     
    Table2 AS Table2_1 
CROSS JOIN
    Table1 AS Table1_1

UNION ALL

SELECT 
    Table1_1.M1, Table2_1.3PrisHTML
FROM     
    Table2 AS Table2_1 
CROSS JOIN
    Table1 AS Table1_1

UNION ALL

SELECT 
    Table1_1.T1, Table2_1.4PrisHTML
FROM
    Table2 AS Table2_1 
CROSS JOIN
    Table1 AS Table1_1

有人有什么建议吗？

编辑:
我确实将值放在一个单独的列中，称为 Column3我可以用它来排序。但我不想显示此栏。有什么建议吗？

只需在 SQL 查询末尾添加一个 Order By 子句即可。无需将其添加到选择查询中。

我会这样做:

    SELECT Column1, Column2 
    FROM
    (
    SELECT Table1_1.F1 AS Column1, Table2_1.1PrisHTML AS Column2, Column3 
    FROM     Table2 AS Table2_1 CROSS JOIN
                      Table1 AS Table1_1
    UNION ALL
    SELECT Table1_1.L1 AS Column1, Table2_1.2PrisHTML AS Column2, Column3 
    FROM     Table2 AS Table2_1 CROSS JOIN
                      Table1 AS Table1_1
    UNION ALL
    SELECT Table1_1.M1 AS Column1, Table2_1.3PrisHTML AS Column2, Column3 
    FROM     Table2 AS Table2_1 CROSS JOIN
                      Table1 AS Table1_1
    UNION ALL
    SELECT Table1_1.T1 AS Column1, Table2_1.4PrisHTML AS Column2, Column3 
    FROM     Table2 AS Table2_1 CROSS JOIN
                      Table1 AS Table1_1
    )
    ORDER BY Column3
