要插入长号,请使用NumberLong()
。它用于处理64位整数。让我们创建一个包含文档的集合-
> db.demo273.insert({ ... Name:"Robert", ... id: NumberLong("100000000000001"), ... isActive:true ...}) WriteResult({ "nInserted" : 1 }) > db.demo273.insert({ ... Name:"David", ... id: NumberLong("98888888888888888"), ... isActive:false ...}) WriteResult({ "nInserted" : 1 }) > db.demo273.insert({ ... Name:"Mike", ... id: NumberLong("999999999999"), ... isActive:true ...}) WriteResult({ "nInserted" : 1 })
在find()
方法的帮助下显示集合中的所有文档-
> db.demo273.find();
输出结果
这将产生以下输出-
{ "_id" : ObjectId("5e4824df1627c0c63e7dbac3"), "Name" : "Robert", "id" : NumberLong("100000000000001"), "isActive" : true } { "_id" : ObjectId("5e4824e01627c0c63e7dbac4"), "Name" : "David", "id" : NumberLong("98888888888888888"), "isActive" : false } { "_id" : ObjectId("5e4824e11627c0c63e7dbac5"), "Name" : "Mike", "id" : NumberLong("999999999999"), "isActive" : true }
