如何在MongoDB中创建一个新对象并获取其保存的对象？
为此，请save()在MongoDB中使用。以下是语法-
var anyVaribaleName=yourValue db.anyCollectionName.save(yourVariableName); yourVariableName;
让我们首先为我们的示例创建一个对象-
> var studentDetails={"StudentName":"Chris","ListOfMarks":[56,78,89],"ListOfSubject":["MySQL","Java","MongoDB"]};让我们保存上面创建的对象“studentDetails”-
> db.demo40.save(studentDetails);
WriteResult({ "nInserted" : 1 })让我们显示值-
> studentDetails;
这将产生以下输出-
{
"StudentName" : "Chris",
"ListOfMarks" : [
56,
78,
89
],
"ListOfSubject" : [
"MySQL",
"Java",
"MongoDB"
],
"_id" : ObjectId("5e177757cfb11e5c34d898e2")
}
