Insert data with a collection object into a SQL Server table - powershell

Question

The code below does not error, it inserts into a SQL Server table with no issues. However the [ServicePrincipalNames] data is not inserted how I planned.
The value that gets inserted into the table is
Microsoft.ActiveDirectory.Management.ADPropertyValueCollection
What I am trying to insert is the value in that object collection which looks like this:
WSMAN/Server1Name
WSMAN/Server1Name.mx.ds.abc.com
TERMSRV/Server1Name
TERMSRV/Server1Name.mx.ds.abc.com
RestrictedKrbHost/Server1Name
HOST/Server1Name
RestrictedKrbHost/Server1Name.mx.ds.abc.com
HOST/Server1Name.mx.ds.abc.com
The code to do the insert is shown here below. How could I change this to have the insert put all the services in the column, separated by |?
$sqlServer='SomeServer'
$catalog = 'SomeDatabase'
$insert = #"
Insert into dbo.ADServers([Name],[OperatingSystem],[OperatingSystemVersion],[ipv4Address],[Created],[Deleted],[whenChanged],[Modified],[Description],[ServicePrincipalNames],[DisplayName],[Location],[DistinguishedName],[DNSHostName])
values('{0}','{1}','{2}','{3}','{4}','{5}','{6}','{7}','{8}','{9}','{10}','{11}','{12}', '{13}')
"#
$start = (Get-Date).ToString('MM/dd/yyyy hh:mm:ss tt')
$connectionString = "Data Source=$sqlServer;Initial Catalog=$catalog;Integrated Security=SSPI"
# connection object initialization
$conn = New-Object System.Data.SqlClient.SqlConnection($connectionString)
#Open the Connection
$conn.Open()
# Prepare the SQL
$cmd = $conn.CreateCommand()
#WMI ouput transformation to SQL table
Get-ADComputer -Filter {operatingSystem -Like 'Windows*server*2019*'} -Property * |`
Select Name,OperatingSystem,OperatingSystemVersion,ipv4Address,Created,Deleted,whenChanged,Modified,Description,ServicePrincipalNames,DisplayName,Location,DistinguishedName,DNSHostName |`
forEach-object{
$cmd.CommandText = $insert -f $_.Name, $_.OperatingSystem, $_.OperatingSystemVersion, $_.ipv4Address, $_.Created, $_.Deleted, $_.whenChanged, $_.Modified,$_.Description, $_.ServicePrincipalNames , $_.DisplayName,$_.Location,$_.DistinguishedName,$_.DNSHostName
$cmd.ExecuteNonQuery()
}
$end = (Get-Date).ToString('MM/dd/yyyy hh:mm:ss tt')
Write-Host $start
Write-Host $end

Answer 1

Ok after a more time googling and learning about out-string. In order to display objects i had to create an expression on that column and rewrite it as below. and it worked
In query replace the
ServicePrincipalNames
with
#{Label="ServicePrincipalNames";Expression={$_.ServicePrincipalNames -join ";" }}
