SQL循环内再加循环问题

SQL code

DECLARE @i INT,    @h INT,@Nun INTSET @i = 0 SET @h = 0SET @Nun = 1WHILE @i < 5 /*循环一*/    BEGIN         WHILE @h < 5/*循环二*/               BEGIN                PRINT  @Nun /*循环一加循环二这里输出应该是25次才对，但他只输出了5次。*/                SET @Nun=@Nun+1                SET @h = @h + 1             END        SET @i = @i + 1     END

像上面怎样能让他在循环二也运行五次，双循环好像内循环只运行一次

SQL code

DECLARE @i INT,    @h INT,@Nun INTSET @i = 0 --SET @h = 0SET @Nun = 1WHILE @i < 5 /*循环一*/    BEGIN         SET @h = 0        WHILE @h < 5/*循环二*/               BEGIN                PRINT  @Nun /*循环一加循环二这里输出应该是25次才对，但他只输出了5次。*/                SET @Nun=@Nun+1                SET @h = @h + 1             END        SET @i = @i + 1     END
