Pull multiple attributes from WMI

Question

Is is possible to query multiple WMI sources like you can multiple tables in SQL?

@"SELECT Win32_Process.ExecutablePath, Win32_Process.Handle, Win32_Process.Name, Win32_PerfFormattedData_PerfProc_Process.WorkingSetPrivate, Win32_PerfFormattedData_PerfProc_Process.PercentProcessorTime  FROM Win32_Process, Win32_PerfFormattedData_PerfProc_Process

This didn't work but hopefully you get the idea. I've searched around and I couldn't even find anyone asking this question. I'm guessing it's not possible but I thought I'd try the experts here before giving up.

No you can't. The WQL language is just a subset of SQL and doesn't supports querys over multiples classes at the same time. Instead you can try the ASSOCIATORS OF sentence, but only in some scenarios.
