最近有一监控业务，由于数据采集到非数字内容，导致监控图表无法正常显示，所以要找出这部分数据，进行删除，然后开发员从源头更正插入数据库的数据，不再产生非数字内容。<wbr style=""><div style=""> 下面举一个例子：</div> <div style=""> <div style="line-height:25px">建立测试数据：</div> <div style="line-height:25px">for(i=1;i&lt;=100;i++){db.test.insert({id:i,content:"test content",name:"wang"+i});}</div> <div style="line-height:25px">&gt;
