Returns the distinct values for a specific attribute in a collection (e.g., Company/name?$filter="name=a*"&$distinct=true)


$distinct allows you to return a collection containing the distinct values for a query on a specific attribute. Only one attribute in the dataclass can be specified. Generally, the String type is best; however, you can also use it on any attribute type that could contain multiple values.

You can also use $skip and $top/$limit as well, if you'd like to navigate the selection before it's placed in an array.


In our example below, we want to retrieve the distinct values for a company name starting with the letter "a":

GET /rest/Company/name?$filter="name=a*"&$distinct=true
