MongoDB查询以获取指定范围内的日期记录
要获取某个范围内的日期记录，请同时使用$gt和$lt。让我们创建一个包含文档的集合-
> db.demo60.insertOne({"ArrivalDate":new ISODate("2019-01-11 12:30:10")});
{
"acknowledged" : true,
"insertedId" : ObjectId("5e2863fecfb11e5c34d89927")
}
> db.demo60.insertOne({"ArrivalDate":new ISODate("2019-10-12 03:10:00")});
{
"acknowledged" : true,
"insertedId" : ObjectId("5e28641acfb11e5c34d89928")
}
> db.demo60.insertOne({"ArrivalDate":new ISODate("2019-01-14 05:11:20")});
{
"acknowledged" : true,
"insertedId" : ObjectId("5e28642acfb11e5c34d89929")
}在find()方法的帮助下显示集合中的所有文档-
> db.demo60.find();
这将产生以下输出-
{ "_id" : ObjectId("5e2863fecfb11e5c34d89927"), "ArrivalDate" : ISODate("2019-01-11T12:30:10Z") }
{ "_id" : ObjectId("5e28641acfb11e5c34d89928"), "ArrivalDate" : ISODate("2019-10-12T03:10:00Z") }
{ "_id" : ObjectId("5e28642acfb11e5c34d89929"), "ArrivalDate" : ISODate("2019-01-14T05:11:20Z") }以下是获取范围内日期记录的查询-
> db.demo60.find({"ArrivalDate": {"$gt":ISODate("2019-01-09T12:30:10Z"), "$lt": ISODate("2019-01-16T12:30:10Z")}});这将产生以下输出-
{ "_id" : ObjectId("5e2863fecfb11e5c34d89927"), "ArrivalDate" : ISODate("2019-01-11T12:30:10Z") }
{ "_id" : ObjectId("5e28642acfb11e5c34d89929"), "ArrivalDate" : ISODate("2019-01-14T05:11:20Z") }
