如下数据格式,如何获取mongodb若干条数据
<code>{ id:1, username:'test', list: [ { name:'t1' }, { name:'t2' } ] } </code>
可以直接获取list分段查询吗?
比如一页显示一条,第一页显示[{name:'t1'}] 第二页显示[{name:'t2'}],这样子
回复内容:
<code>{ id:1, username:'test', list: [ { name:'t1' }, { name:'t2' } ] } </code>
可以直接获取list分段查询吗?
比如一页显示一条,第一页显示[{name:'t1'}] 第二页显示[{name:'t2'}],这样子
可以用MongoDB的聚合框架
db.test.aggregate([ {$match: {id:1}}, {$unwind: "$list"}, {$sort:{'list.name':1}}, {$skip:5}, {$limit: 5}]); // 取得list下面从第6个到第10个
