Example 1: Retrieve stores with sales exceeding $35,000

To retrieve a store with over $35,000 in sales, first run a query with $gt operator on the sales.totalSales field. Then limit the query results to one store.

db.stores.find({
    "sales.totalSales": {
        $gt: 35000
    }
}, {
    name: 1,
    "sales.totalSales": 1
}, {
    limit: 1
})

The first result returned by this query is:

[
    {
        "_id": "2cf3f885-9962-4b67-a172-aa9039e9ae2f",
        "name": "First Up Consultants | Bed and Bath Center - South Amir",
        "sales": { "totalSales": 37701 }
    }
]

Example 2: Find a store with more than 12 full-time staff

To find a store with more than 12 full time staff, first run a query with the $gt operator on the staff.totalStaff.fullTime field. Then project just the name and totalStaff fields and limit the result set to a single store from the list of matching results.

db.stores.find({
    "staff.totalStaff.fullTime": {
        $gt: 12
    }
}, {
    name: 1,
    "staff.totalStaff": 1
}, {
    limit: 1
})

The first result returned by this query is:

[
    {
        "_id": "2cf3f885-9962-4b67-a172-aa9039e9ae2f",
        "name": "First Up Consultants | Bed and Bath Center - South Amir",
        "staff": { "totalStaff": { "fullTime": 18, "partTime": 17 } }
    }
]
