To perform a Repository Query Language (RQL) query, send a Legacy REST Web Services request as described in the following table. See information about repository queries in ATG Repository Guide.

Request Component

Value

HTTP Method

GET

Functional Parameters

Include the atg-rest-rql functional parameter. Set its value to the RQL query you want to execute.

If you include this parameter as a URL query string, make sure that you URL encode the RQL query. For example, the query ALL RANGE +4 should be encoded as ALL+RANGE+%2B4.

URL

Include the component pathname of the repository item type that you want to query in the application path after /rest/repository/.

The following example shows a Legacy REST Web Services request that performs an RQL query. It returns the first four items of item type product in the /atg/commerce/catalog/ProductCatalog repository.

curl -v -b cookies.txt -X GET \http://myserver:8080/rest/repository/atg/
commerce/catalog/ProductCatalog/product?atg-rest-rql=ALL+RANGE+%2B4

Note: You can include the atg-rest-rql functional parameter in the message body of a POST HTTP request if you prefer not to URL encode your RQL queries. Use the atg-rest-view control parameter to instruct the Legacy REST Web Services server to handle your POST request as a GET request. See Handling POST Requests as Other Methods.

Note: Do not include parameters in the RQL queries that you perform via the Legacy REST Web Services. Make sure that all constants are explicitly included in the RQL statements. See information about parameters in RQL queries in the ATG Repository Guide.
