SQL Queries for vCentre Database

Hi,

I'm trying to put together a sql query that will return all VM's in our inventory with certain information and 3 or more custom attributes.

I can get a query to return v.NAME, v.IP_ADDRESS, v.MEM_SIZE_MB, v.NUM_VCPU, v.GUEST_OS, v.DESCRIPTION however I would also like the amount of storage space the VM uses as well as my custom attriubutes to appear.

Can anyone help please?
