ตัวอย่างเอกสารและซับเอกสารใน MongoDB พร้อมการอัปเดต

ไวยากรณ์สำหรับการสร้างเอกสารและซับเอกสาร (subdocument)

db.yourCollectionName.insertOne(
    {
        yourFiledName:yourValue,
        yourFieldName : [
            {
                yourFiledName1,
                yourFiledName2,
                .
                .
                N
            }
        ]
    }
);

ตัวอย่างการสร้างคอลเล็กชันพร้อมเอกสาร

> db.demo706.insertOne(
    {
        PortalName: "GameApplication",
        ApplicationConfiguration : [
            {
                "URL": "jdbc:mysql://localhost/customer_tracker?autoReconnect=true",
                "USERNAME": "root",
                "PASSWORD": "root"
            }
        ]
    }
);
{ "acknowledged" : true, "insertedId" : ObjectId("5ea6f557551299a9f98c93c6") }
> db.demo706.insertOne(
    {
        PortalName: "WebMyBusinessApplication",
        ApplicationConfiguration : [
            {
                "URL": "jdbc:oracle:thin:@localhost:1521:xe",
                "USERNAME": "App",
                "PASSWORD": "App"
            }
        ]
    }
);
{ "acknowledged" : true, "insertedId" : ObjectId("5ea6f558551299a9f98c93c7") }

แสดงเอกสารทั้งหมดด้วยเมธอด find()
