PowerShell script to list items in collection - sql-server

Question

I'm new to PowerShell and am trying to query against my SQL server. I get the idea of creating a new-psdrive and then navigating to databases etc and have a line of code as
$dbs = (get-childitem
sqlserver:\sql\SERVER\INSTANCE\databases)
when I pipe the $dbs to a foreach, how would I get results of a collection of the database object? I am trying to read the extendedproperties of my test database.
This single query gives the results I want repeated for each database.
set-location
DRIVENAME:\databases\beagle_test\extendedproperties
get-childitem | select displayname,
value
any help very much appreciated.

Answer 1

I dont have SQL server handy to try this. Let me know the result
Set-Location DRIVENAME:\Databases
Get-ChildItem | % { Get-ChildItem $("$_.Name\extendedproperties") | Select DisplayName, Value }

Answer 2

Try this
Set-Location DRIVENAME:\Databases
Get-ChildItem | foreach-object { if (Test-Path $("$.Name\extendedproperties")) { Get-ChildItem $("$.Name\extendedproperties") | Select DisplayName, Value } }
The second line here is a single statement. What I am doing is to check if Extendedproperties exist and then get child item.

Answer 3

How about:
dir sqlserver:\sql\ServerName\InstanceName\Databases\*\ExtendedProperties\* |
select #{Name="Database";Expression={$_.Parent.Name}}, Name, Value

Answer 4

How about just:
dir SQLSERVER:\SQL\Server\Instance\databases\*\extendedproperties\* | % {select $_.displayname, $_.value}

Answer 5

so, many years later I am looking into my SO stats and see this old question and figure that my powershell skills have grown a little since 2010.
The use-case has long gone but I think what I was trying to achieve is this:
foreach ($db in $SMOServer.databases | Where-Object status -eq 'normal') {
$db.ExtendedProperties | Select-Object #{name = "DBName"; expression = {$db.Name}}, name, value
}
which gives results like this:
DBName Name Value
