Performing an SQL-like JOIN operation

Good day,

I’d like to perform the equivalent of an SQL-like JOIN operation (i.e. not a UNION) in order to add the following fields:

• Win32_Process.CommandLine
• Win32_Process.Description

…to the following command output, which lists the processes with the top 10 private working set values.

Get-WmiObject -class Win32_PerfFormattedData_PerfProc_Process -Filter "Name <> '_Total'" | Sort-Object -Property WorkingSetPrivate -Descending | Select-Object -First 10 | Where-Object {$_.Name -Like $processName+"*"} | Select-Object @{Name="Process Id"; Expression = {$_.idprocess}}, @{Name="Counter Name"; Expression = {$_.name}}, @{Name="Private Working Set"; Expression = {$_.workingSetPrivate / 1kb}}

Do I have to loop through each of the above processes and performing multiple WQL queries, or is there a more elegant way of achieving the desired result?

Thanks,

Larry
