使用cordova可以很方便的在手机sdcard中读写文件。
首先需要安装cordova插件：file
命令为：
cordova plugin add org.apache.cordova.file
然后就可以读写文件了，这里我先是写入一个文件，具体的JS代码为：
var datas=null;//datas need write
var directory=&
SELECT cust_id,
SUM(price) as total
FROM orders
WHERE status = 'A'
GROUP BY cust_id
HAVING total > 250
db.orders.aggregate( [
{ $match: { status: 'A' } },
{
$group: {
