Why does my query only show clients when there is no criteria defined?

Question

My query simply wants to display different properties of a computer.  There is no limiting criteria and yet it will only display those systems that are SCCM clients. The collection is an AD OU with both clients and non-clients. Here is my query.  Thank
you.
select SMS_R_System.ADSiteName, SMS_R_System.DistinguishedName, SMS_R_System.IPAddresses, SMS_R_System.LastLogonUserName, SMS_R_System.Name, SMS_G_System_DESKTOP_MONITOR.Description, SMS_G_System_SYSTEM_ENCLOSURE.SerialNumber, SMS_G_System_PHYSICAL_MEMORY.Capacity,
SMS_G_System_LOGICAL_DISK.Name, SMS_G_System_LOGICAL_DISK.Size, SMS_G_System_COMPUTER_SYSTEM.Manufacturer, SMS_G_System_COMPUTER_SYSTEM.Model, SMS_R_System.Client from  SMS_R_System inner join SMS_G_System_PHYSICAL_MEMORY on SMS_G_System_PHYSICAL_MEMORY.ResourceID
= SMS_R_System.ResourceId inner join SMS_G_System_LOGICAL_DISK on SMS_G_System_LOGICAL_DISK.ResourceID = SMS_R_System.ResourceId inner join SMS_G_System_COMPUTER_SYSTEM on SMS_G_System_COMPUTER_SYSTEM.ResourceID = SMS_R_System.ResourceId inner join SMS_G_System_SYSTEM_ENCLOSURE
on SMS_G_System_SYSTEM_ENCLOSURE.ResourceID = SMS_R_System.ResourceId inner join SMS_G_System_DESKTOP_MONITOR on SMS_G_System_DESKTOP_MONITOR.ResourceId = SMS_R_System.ResourceId

They don't negate non-client results -- your query does because it is using inner joins. Inner joins drop rows in the "left" table if there is no matching row (based on the join condition) in the "right" table.
The SMS_G_System_DESKTOP_MONITOR probably does not have any rows for your non-client resources and so the entire row gets dropped. That's how inner joins work. If you don't want this to happen, then you need to use an outer join -- typically a left outer
join is what you want. This is all SQL specific and has nothing to do with ConfigMgr. It also has nothing to do with SSRS.
There are tons of great resources on both SQL and SSRS -- just use Bing.
