# AirData Querying Capabilities

AirData Queries can perform basic CRUD operations on your AirData. Typically, this is done by creating Data Flows – specifically, ones that include [AirData Request Data Operation](../../data-operations/airdata-request-data-operation) – in the [Connections Builder](../../studio/builder-bar/connections-builder). The AirData Request Data Operation can also be run in the Connections Builder directly, either to test that a Query runs as intended or to perform a one-off interaction with your data.

There are a number of built-in methods available that allow you to interact with entries in the datastore such as **QUERY**, **PUT**, **DELETE**, **INSERT**, and **PATCH**. For more details, see the [AirData Request](../../data-operations/airdata-request-data-operation) Data Operation. Here, we focus here on the **QUERY** method and how you can use built-in [filtering](../../airscript/filtering-data-using-query-expression) to hone in on your data.

For the following examples, let’s say we have a sample App Object in our Datastore called Dog. Each Dog entry has the following schema:

```json
{
  "name": "Text",
  "Nicknames": "List<Text>",
  "breed": "Text",
  "age": "Integer",
  "owner": "Text",
  "isTrained": "Boolean"
}
```

The following is an example of an instance of a Dog:

```json
{
  "name": "Goofy",
  "nicknames": [
    "goofy",
    "goofball"
  ],
  "breed": "pug",
  "age": 7,
  "owner": "Reyna",
  "isTrained": true
}
```

Let’s use this sample Datastore below with nine Dog entries and explore some of the filters available to query the Datastore.![](https://2093598723-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FC2DgLBPTrwoEhWaU24LL%2Fuploads%2Fgit-blob-8c23a1514b6e60e39f5ec81ba407e22d52c04416%2Fairdata-querying-capabilities-v180-1.png?alt=media)

These are the specifications of all the available per-field filters, grouped by categorical type of search. For AirData querying, the documentation format is used as such:

**filterKeyWord**: the primary name for the filter.

**type**: the Airkit data type of the field that you wish to query (text, list of texts, etc)

**aliases**: can be used to clarify the intent of or shorten your query using different filter key words.

For example, the following queries will operate identically:

```javascript
{ "age": { "<": 2 } }
```

```javascript
{ "age": { "lessThan": 2 } }
```

**example query**: A valid sample query based on the example datastore.

**query returns**: A description of what the sample query would return from example datastore.

Our example returns 1,2,4,5,8, & 9." }, "cols": 5, "rows": 6 } \[/block]

## Sorting data

In order to sort data from Airdata, add a [Transform](../../data-operations/the-transform-data-operation) Data Operation downstream of the AirData Request and use LINQ Syntax to specific how the data should be sorted.

For instance, if you are querying to get all dogs that are less than two years old and need to sort the results such that you have a list of the each dog's ages in descending order, you would use the following expression:

```
FROM item IN airData.results ORDER BY item.age DESCENDING SELECT item.age
```

## Examples

You can use Airscript to further refine your search. For example:&#x20;

```javascript
{ "dogName": { "anyOf": "{{ LOWERCASE("LUCY")}}" } }
```

You can combine multiple queries to specify your search.&#x20;

```javascript
{ "dogName": { "insensitiveAnyOf": "daisy" }, "dogAge": { "greaterThan": 4 } }
```

> 📘 Note: Comma delimited queries function as an AND operation, not OR.
