Feedback

This one is from Aaron Nelson aka SQLVariant:

I have a PowerShell question for you gurus. I know precisely how to do this in SQL, but I’m only kinda-sure how to do this in PowerShell.

My question is how do you contain an OR to only a certain portion of a Where-Object? In SQL all you have to do is put parens around the clauses and that will make their results act as one ‘where’ clause. In PowerShell all I could think to do is to break it up into multiple Where-Object statements. There has to be a better way to do this right?

SQL Example:

WHERE (NAME LIKE '%SQL%'

       OR NAME LIKE 'Reporting%')

   AND StartMode = 'Auto'

   AND Started != 'True'

PowerShell Example (that doesn't work)

Get-WmiObject win32_service -ComputerName AARON |

Where {$_.name -match "^*SQL*" -or $_.name -match "Report"} |

Where {$_.StartMode -eq "Auto" -and $_.Started -ne "True"} |

Select SystemName, Name, StartName, Started, StartMode | Ft -a

Hal's answer: 

Review the Operator Precedence help page, you'll see that -and -or are near the bottom, so you need parentheses to make this work. For example:

get-stuff | ? { ($_ -gt $x) -and ($_ -ne $y) }
