Examples

This section contains examples of how to use this query language construct.

Consider this sample set of documents within the Products collection for these examples.

[
  {
    "name": "Minet Hat",
    "price": 50,
    "detailCategory": "apparel-accessories-beanies"
  },
  {
    "name": "Klinto Hat",
    "price": 65,
    "detailCategory": "apparel-accessories-beanies"
  },
  {
    "name": "Benki Hat",
    "price": 25,
    "detailCategory": "apparel-accessories-beanies"
  },
  {
    "name": "Jontra Hat",
    "price": 40,
    "detailCategory": "apparel-accessories-beanies"
  }
]

Filter within a range of values

In this example, the BETWEEN keyword is used to filter products within a specific price range. The range is inclusive of the lower and upper bounds.

SELECT VALUE
  p.name
FROM
  products p
WHERE
  (p.price BETWEEN 0 AND 40) AND
  p.detailCategory = "apparel-accessories-beanies"

[
  "Benki Hat",
  "Jontra Hat"
]

Evaluate price range for each product

In this example, the BETWEEN keyword is used to evaluate whether each product's price falls within a specific range by using the keyword in the SELECT clause. The result includes the product name and a boolean indicating if the price is within the range.

SELECT
  p.name,
  (p.price BETWEEN 10 AND 20) AS lowPrice
FROM
  products p
WHERE
  p.detailCategory = "apparel-accessories-beanies"

[
  {
    "name": "Minet Hat",
    "lowPrice": false
  },
  {
    "name": "Klinto Hat",
    "lowPrice": false
  },
  {
    "name": "Benki Hat",
    "lowPrice": false
  },
  {
    "name": "Jontra Hat",
    "lowPrice": false
  }
]
