SQL中的Continue和Break

x

在Sql Server中,sql语句包含While循环的时候,肯定都或多或少的用到Continue和Break...

下面撸了一个小Demo

Declare @Index Int = 0,@EndIndex Int = 0

While  @Index < 100
    Begin
        Set @EndIndex = @EndIndex + 1
        Print Continue 之后Index增加... + Convert(Varchar(1000),@Index)
        If @EndIndex > 100
            Begin
                Print 防止死循环...*************************************************
                Break
            End
            
        Continue
        Set @Index =@Index + 1
    End

Set @Index = 0

While  @Index < 100
    Begin
        Print Continue 之前Index增加... + Convert(Varchar(1000),@Index)
        Set @Index =@Index + 1
        Continue
    End

Set @Index = 0
While  @Index < 100
    Begin
        Print Break Index... + Convert(Varchar(1000),@Index)
        Break
    End
