| − | === Create a Collection ===
| |
| − |
| |
| − | If a collection does not exist, MongoDB creates the collection when you first store data for that collection.
| |
| − |
| |
| − | You can create one and set some options:
| |
| − |
| |
| − | db.createCollection('deptCollection', {autoIndexID : true})
| |
| − |
| |
| − | The following example will create a collection representing the DEPT/EMP tables seen in the [[Oracle_Sample_Data|Oracle Sample Data]].
| |
| − |
| |
| − | Add department 10 and it's employees:
| |
| − |
| |
| − | db.deptCollection.insert(
| |
| − | {
| |
| − | deptno: 10,
| |
| − | dname: 'ACCOUNTING',
| |
| − | loc: 'NEW YORK',
| |
| − | employees: [
| |
| − | {
| |
| − | empno: 7782,
| |
| − | ename: 'CLARK',
| |
| − | job: 'MANAGER',
| |
| − | mgr: 7839,
| |
| − | hiredate: new Date('1989-JUN-09'),
| |
| − | sal: 2450
| |
| − | },
| |
| − | {
| |
