创建图表事件监听非常简单:首先是通过addEventListener('监听类型',js监听方法)添加事件监听,然后在js监听方法中定义具体监听逻辑。
以钻取操作为例,当用户点击图表某一个point的时候弹出point的name和value,代码如下:
<script>
//创建AnyChart
var chart = new AnyChart();
//添加钻取操作&quo
我们来看下面的例子:
create or replace view testview
as
select empno,ename from emp where ename like ‘M%’
with check option;
这里我们创建了一个视图,并使用了with check option来限制了视图。 然后我们来看一下视图包含的结果:
select * from testv
