# Introduction
The `WixDataQuery` functions enable you to run, sort, filter, and control
 which results a query returns.

 Typically, you build a query using the [`query()`](wix-data.html#query) function,
 refine the query by chaining `WixDataQuery` functions, and then execute the
 query by chaining *one* of the following: [`find()`](#find), [`distinct()`](#distinct), or [`count()`](#count)

 For example, the following code queries a collection for all male customers
 over the age of 20 and logs the first 15 results to the console, sorted in
 ascending order by name:

 ```javascript
 import wixData from 'wix-data';

 wixData.query("Customer")
   .gt("age", 20)
   .ascending("name")
   .limit(15)
   .find()
   .then((results) => {
     console.log(results.items);
   });
 ```

When working with [Wix app collections](https://support.wix.com/en/article/velo-working-with-wix-app-collections-and-code), fields in the collections have the following permissions:
 + Can connect to data
 + Can use in dynamic page URL
 + Can be sorted
 + Can be filtered
 + Read-only
Check [which fields](https://support.wix.com/en/search?term=velo%20collection%20fields) can be used in a query.
