# EntityQueryProperties

A type that provides the properties to include in a property-matched query.

```
struct EntityQueryProperties<Entity, ComparatorMappingType> where Entity : AppEntity
```

## Overview

Contains all the supported properties a user can query against an entity for a given query.
Declare query properties with a block containing all applicable [`EntityQueryProperty`](/documentation/AppIntents/EntityQueryProperty) objects.

## Example

```
var properties = QueryProperties {
    Property(\.$myDate) {
        LessThanComparator { /* ... body of mapping transform ... */ }
        GreaterThanComparator { /* ... body of mapping transform ... */ }
    }
    Property(\.$myArray) {
        ContainsComparator { /* ... body of mapping transform ... */ }
    }
}
```

## Topics

### Creating the query properties

[`init(properties: () -> [EntityQueryPropertyDeclaration<Entity, ComparatorMappingType>])`](/documentation/AppIntents/EntityQueryProperties/init(properties:))

[`enum EntityQueryPropertiesBuilder`](/documentation/AppIntents/EntityQueryPropertiesBuilder)

A result builder that allows you to declaratively describe the properties to include in a property-matched query.

### Getting the query properties

[`subscript(Int) -> EntityQueryPropertyDeclaration<Entity, ComparatorMappingType>`](/documentation/AppIntents/EntityQueryProperties/subscript(_:))
