创建以下临时表：

  CREATE TABLE #BEDRAGEN(Dossiercode T_Code_Dossier,Detailcode T_Code_Detail,DetailSubcode T_Code_DetailSub
                        ,Totaalbedrag T_Fin_Amount,TotGefactDiensten T_Fin_Amount, TotGefactgoederen T_Fin_Amount, Verzonden int

  WHERE    DD.DossierCode > N''

 select * from #bedragen

 drop table #BEDRAGEN

您可以看到子查询来获取列TotaalInkord，TotaalInkRgls，Inkooporder，InkOrdRgl 正在使用相同的from / innerjoin和where。

是否可以将这些组合？ 如果可以合并会更快吗？

谢谢

背景： 我需要此临时表来加快存储过程的性能。 该存储过程是一个很大的选择，它使用许多函数来获取其列。 我现在已在模板中添加了此功能内容。

很难获得示例数据，但是使用CROSS APPLY可以解决问题-无法说出它是否会更好（虽然应该如此），您可能需要对此稍作调整。

  INSERT INTO #BEDRAGEN
