mangodb命令

1、分组求和查询命令

 db.getCollection('crm_batch_call').aggregate([{ $match: {"call_time":{"$gte":ISODate("2019-08-28T00:00:00.000+0000"),"$lte":ISODate("2019-08-28T15:59:59.000+0000")},//大于小于条件"call_result_desc" : {$ne:'接通'},//非等于"gw_id":{$exists:true},//是否存在"customer_id":{$in:[1,2]}//in操作"wordstemplate_name":/催告/ //模糊查询}},{$group: {_id: {"call_result_code":"$call_result_code","call_result_desc":"$call_result_desc"},num:{$sum:1}}}
]).forEach(function(document){print("\r\n"+document._id.call_result_desc+","+document.num)});

2、链表查询

 db.getCollection('crm_batch_call').aggregate([{$match: {customer_id:67,"call_time":{"$gte":ISODate("2019-07-22T00:00:00.000+0000"),"$lte":ISODate("2019-07-24T15:59:59.000+0000")}}},{$lookup:{from: "crm_call_record",//连接的表（B表）localField: "uid",//A表的连接条件foreignField: "uuid",//B表的连接条件as: "call_text"//连接结果别名}},{$project:{"uid":1,batch_no:1,phone:1,wordstemplate_name:1,robot_name:1,call_result_desc:1,intent:1,call_time:1,bill_duration:1,"call_text":{"atext":1,"btext":1,"sort":1}}
}
])

3、分组后数据求和

db.getCollection('crm_call_record').aggregate([{$match: {"time": {"$gte": ISODate("2019-01-24" + "T00:00:00.000+0000"),"$lte": ISODate("2019-01-24" + "T15:59:59.000+0000")}}
},
{$project: {"uuid": 1}
},
{$group: {_id: "$uuid"}
},
{$group: {_id: null,count: {$sum: 1}}
}])
