PowerShell: Unique Array of Objects - powershell

Question

I've got an array of objects for team names and emails as well as the tickets associated to that team in a seperate array however its not working quite as expected and I've been stumped on this one for sometime...
code:
$teamConfig = #(
[pscustomobject]#{
TeamName='Team1';
}
)
$query = "select * from INCAutomation"
$results = Invoke-Sqlcmd -query $query -ServerInstance 'localhost' -Database 'AyushTest'
$collectionWithItems = #()
$array = #()
foreach ($i in $results) {
foreach ($x in $teamConfig) {
if ($i.TeamName -eq $x.TeamName) {
$array += $i.TicketID
$temp = New-Object System.Object
$temp | Add-Member -MemberType NoteProperty -Name "TeamName" -Value $i.TeamName
$temp | Add-Member -MemberType NoteProperty -Name "TeamEmail" -Value $i.TeamEmail
$temp | Add-Member -MemberType NoteProperty -Name "TicketID" -Value $array
$collectionWithItems += $temp
}
}
}
$collectionWithItems = $collectionWithItems | select 'TeamName', 'TeamEmail', 'TicketID' -Unique
$collectionWithItems
Output:
TeamName TeamEmail TicketID
-------- --------- --------
Team1 Team1#test.com {INC0001}
Team1 Team1#test.com {INC0001, INC0002}
Team1 Team1#test.com {INC0001, INC0002, INC0003}
Team1 Team1#test.com {INC0001, INC0002, INC0003, INC0004}
Desired output:
TeamName TeamEmail TicketID
-------- --------- --------
Team1 Team1#test.com {INC0001, INC0002, INC0003, INC0004}
The other thing I am confused about as well is that this will need to work with multiple teams for example:
$teamConfig = #(
[pscustomobject]#{
TeamName='Team1';
}
[pscustomobject]#{
TeamName='Team2';
}
[pscustomobject]#{
TeamName='Team3';
}
)
and as a result, the desired output should be:
TeamName TeamEmail TicketID
-------- --------- --------
Team1 Team1#test.com {INC0001, INC0002, INC0003, INC0004}
Team2 Team2#test.com {INC0005, INC0006, INC0007, INC0008}
Team3 Team3#test.com {INC0009, INC0010, INC0011, INC0012}
Thanks in advance!

Answer 1

Your outer loop should iterate over $teamConfig so that you only go through each team once.
To get the tickets associated with the current team name, you can use Where-Object, like so:
$ticketIds = $results |Where-Object TeamName -eq $team.TeamName |Select -ExpandProperty TicketID
Allowing you to simplify your code greatly:
$teamConfig = #(
[pscustomobject]#{
TeamName = 'Team1'
TeamEmail = 'team1#domain.tld'
}
[pscustomobject]#{
TeamName = 'Team2'
TeamEmail = 'team2#domain.tld'
}
[pscustomobject]#{
TeamName = 'Team3'
TeamEmail = 'team3#domain.tld'
}
)
$query = "select * from INCAutomation"
$results = Invoke-Sqlcmd -query $query -ServerInstance 'localhost' -Database 'AyushTest'
$teamTickets = foreach($team in $teamConfig){
# Filter tickets based on team name
$ticketIds = $results |Where-Object TeamName -eq $team.TeamName |Select -ExpandProperty TicketID
# Output a single object per team, with all ticket IDs attached
$team |Select TeamName,TeamEmail,#{Name='TicketID';Expression={ $ticketIds }}
}
$teamTickets now contains exactly one object per team in $teamConfig.
