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
