MSSQl 'GO' handling in Powershell connection String - sql-server

Question

I have a sql query which is patched with a Go to check the orphan objects in mssql.
use DBName
go
sp_change_users_login 'report'
Now, I am automating the above in Powershell for all the user databases and trying to get the orphan users.
Here is the code:
if($port)
{
$connectionString ="server=$servername,$port;Integrated Security=true;" #uid=$DBUserName; pwd=$dbpwd;Database=$DB;
}
else
{
$connectionString ="server=$servername;Integrated Security=true;"
}
$connection = New-Object System.Data.SqlClient.SqlConnection -ea Stop
$connection.ConnectionString=$connectionString
$connection.Open()
$db_query = #"
Select name from sys.sysdatabases where dbid > 4 and name not in ('ReportServer')
"#
$command = $connection.CreateCommand()
$command.CommandText = $db_query
$result = $command.ExecuteReader()
$object= New-Object System.Data.DataTable
$object.Load($result)
[System.Array]$DBs = $object.name
if($DBs -is [System.Array])
{
foreach($DB in $DBs)
{
## PROBLEM IS HERE ###
$orphan_users_query = #"
use $DB
GO
sp_change_users_login 'report'
"#
$command = $connection.CreateCommand()
$command.CommandText = $orphan_users_query
$result = $command.ExecuteReader()
$object= New-Object System.Data.DataTable
$object.Load($result)
$object | Out-File C:\temp\outfile_property.txt -Append -Force
}
}
Problem is PS cannot identify the go separator because it is specific to MSSQL/SSMS. So, how can I still iterate and run the query in all user databases without creating multiple connections specific to each DB?

Answer 1

Calling ChangeDatabase on the connection is an alternate means of switching databases.
You can then just execute sp_change_users_login as is. No need for GO.
