获取MongoDB Shell脚本的输出？
您可以使用printjson()或print()获取MongoDBShell脚本的输出。让我们创建一个对象数组。
以下是创建对象数组的查询。
> var studentDetails=[{"StudentName":"John","StudentAge":21},
{"StudentName":"Carol","StudentAge":24},{"StudentName":"David","StudentAge":25}];以下是使用printjson()-获取MongoShell脚本输出的查询-
> printjson(studentDetails);
这将产生以下输出-
[
{
"StudentName" : "John",
"StudentAge" : 21
},
{
"StudentName" : "Carol",
"StudentAge" : 24
},
{
"StudentName" : "David",
"StudentAge" : 25
}
]
> var studentDetails=[{"StudentName":"John","StudentAge":21},
{"StudentName":"Carol","StudentAge":24},{"StudentName":"David","StudentAge":25}];
