Using Linked Queries
Linked queries can be used with both Orbital Catalog queries or existing user built queries. For this reason, in order to use linked queries, you need to select one or more existing queries.
This section describes how to use the Orbital user interface to create linked queries.
Accessing Linked Queries
There are two paths you can take to access the linked queries feature. Both paths will require you click the Linked Queries button 
.
Accessing Linked Queries from the Query Page
The first access path we will discuss is accessing the linked queries feature from the Queries page. To access linked queries from the Query page:
- Click the Query tab to display the Query page, as shown below.
This will display the Query page.
- Click Link Queries located underneath the Endpoints field, as shown in the figure below.
This will display a dropdown listing existing queries, as shown in the figure below.
Note: The Existing Queries dropdown will display the last 50 existing queries. If you wish to select one or more queries that are older than the 50 listed in this dropdown, you will have to use the Results page.
3. Navigate to the desired existing query.
4. Select the existing query by clicking the check box to the left of the query name.
Note: You can select more than one existing query by clicking on multiple check boxes.
5. Click Add, as shown in the figure below.
This will populate the Endpoints field with the name of the existing query, as shown in the figure below.
- Once you have identified the existing query or queries you want to run your query against, you can either write your own queries in the Custom SQL field or select a built-in query from the Query Catalog.
Refer to Query for more information on using queries.
Accessing Linked Queries from the Results Page
