次に、必要なものを選択します。例えば

：

declare @nodenumbers table (num int primary key); 
insert into @nodenumbers (num) values (2),(3),(5),(8),(12),(19),(21); 

select Title, [URL Local], [URL Site] from @VarTable where id in (select num from @nodenumbers);

または：追記として

select Title, [URL Local], [URL Site] from @VarTable where [URL Local] like '%-notebook-%';

。 xqueryを使用して特定の数のノード位置だけを返すことは、実際には可能です。しかし、この場合はnodes（）がリテラルを必要としているため厳密に扱うので役に立ちません。

FROM @htmlXML.nodes('//div[@class="widget_fcats_box clearfix"][position() = (2,3,5,8,12,19,21)]') as t(v);

@TableVariableは他の変数と同じです。宣言すると、コードを実行する間だけ存在します。 #TempTableは、セッション中にのみ存在する実際のテーブルです。切断すると消えます。 [Here]（http://sqlhints.com/tag/temporary-table-vs-table-variable/）にはそれらに関する記事があります。 – LukStorms
