Assistance in converting SQL to SWQL

I have the following SQL query that runs on one Orion instance. 

SELECT

  Containers_AlertsAndReportsData.GroupName AS 'Core Network Path',

  CAST(AVG(CAST(Containers_ContainerAvailability.GroupPercentAvailability as DECIMAL(10,2))) AS DECIMAL(10,2)) as 'Percent Availability'

FROM

  Containers_AlertsAndReportsData with (nolock) INNER JOIN Containers_ContainerAvailability with (nolock) ON (Containers_AlertsAndReportsData.GroupID = Containers_ContainerAvailability.GroupID)

WHERE

  DateTime BETWEEN DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE()) - 1, 0) AND DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE()), 0) AND 

    Containers_AlertsAndReportsData.GroupName LIKE 'My Core Network%'

GROUP BY

  Containers_AlertsAndReportsData.GroupName,Containers_AlertsAndReportsData.GroupID

ORDER BY

    Containers_AlertsAndReportsData.GroupName ASC

I would like to run it from the EOC and have it combine the results from 3 Orion instances.

• Question 1: Can I convert the above query to SWQL?
• Question 2: When / if I run it from the EOC, will it automatically query all 3 instances and pull the data together into a single report?
