SQL“with”子句

Question

是否有任何其他方式来重组这个，而不是使用“WITH” clasue？

下面是代码：

CREATE table #TEMP 
    (
      RowNum int identity, 
      ItemId int, 
      LevelId int, 
      Id int,   
      Depth int 
    ) 

    ;WITH CTEAlias 
    (ItemId, LevelId, Id, Existingdepth) as 
    (
     Select ItemId, LevelId, Id, 0 as ExistingDepth 
     From tblNavItems 
     Where NavLevelId In 
     (Select NavLevelId 
      From tblNavLevels 
      Where SoltnId = @FromSoltnID 
      And NavTypeId = @NavTypeId1) 
     And ParentId = -1 
     Union All 
     Select tni.ItemId, tni.LevelId, tni.Id, ExistingDepth+1 
     From tblNavItems as tni 
      Join CTEAlias as ca 
       On tni.Id = ca.ItemId 
     Where tni.LevelId In 
      (Select NavLevelId 
      From tblNavLevels 
      Where SoltnId = @FromSoltnID 
       And NavTypeId = @NavTypeId1) 
    ) 
    INSERT INTO #TEMP(ItemId, LevelId, Id,Depth) 
    Select * FROM CTEAlias Order BY Id 

我不想“与”条款中，也没有别名。 请让我知道是否有任何其他方式来重写这可能使用两个表？

如果目的是选择数据到临时表中，你可以做如下无“WITH”。

CREATE table #TEMP ( dt1 datetime, id1 int) 
INSERT INTO #TEMP(dt1, id1) 
SELECT * FROM (
      Select ab, bc 
      From UY420 
      where bc=100000 
     ) a
