SQL-选择具有多个where的AS

Question

我想将SQL查询的输出显示如下。

| COUNT_A | COUNT_B | COUNT_C | COUNT_D |

| 2 | 3 | 4 | 5 |

我使用UNION ALL获得的当前输出是

| COUNT_A |

2
3
4
5

var element = $(".element"); 
        $(window).scroll(function () {
            var scroll = $(window).scrollTop();
            for(var i = 0; i < element.length;i++){
                if(scroll > element.eq(i)){
                    element.eq(i).addClass("newClass");
                }
   }
})

我可以请求别人的帮助。我不擅长这个。
