How do I pause PowerShell to see an error? - powershell

Question

I have tried every recommendation from the link below, but nothing works.
How do you do a ‘Pause’ with PowerShell 2.0?
Here is my code:
Read-Host -Prompt "Press Enter to continue"
Invoke-Sqlcmd -Query "Select * from TBL_AGG_BOC" -ServerInstance "server_name\SQL2008" -Database "db_name" > "C:\Users\TBL_AGG_BOC.txt"
Read-Host -Prompt "Press Enter to continue"
The script keeps failing, and it shuts down so fast that I can't see what is actually happening. How can I force this to stay open for a few seconds so I can see what is happening here?
The file is saved and named 'test_export.ps1', and I right-click the file and then click 'Run with PowerShell' to fire it off. I don't have administrator rights on this machine. I hope that's not a problem.

Finally I got this working. It was a combination of a few things.
Open PowerShell as Administrator and run Set-ExecutionPolicy -Scope CurrentUser
Provide RemoteSigned and press Enter
Run Set-ExecutionPolicy -Scope CurrentUser
Provide Unrestricted and press Enter
This link helped a lot!
PowerShell says "execution of scripts is disabled on this system."
Then, run this:
$server = "SERVERNAME\INSTANCE"
$database = "DATABASE_NAME"
$tablequery = "SELECT name from sys.tables"
# Declare connection variables
$connectionTemplate = "Data Source={0};Integrated Security=SSPI;Initial Catalog={1};"
$connectionString = [string]::Format($connectionTemplate, $server, $database)
$connection = New-Object System.Data.SqlClient.SqlConnection
$connection.ConnectionString = $connectionString
$command = New-Object System.Data.SqlClient.SqlCommand
$command.CommandText = $tablequery
$command.Connection = $connection
# Load up the tables in a dataset
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $command
$DataSet = New-Object System.Data.DataSet
$SqlAdapter.Fill($DataSet)
$connection.Close()
# Loop through all tables and export a CSV of the table data
foreach ($Row in $DataSet.Tables[0].Rows)
{
$queryData = "SELECT * FROM [$($Row[0])]"
# Specify the output location of your dump file
$extractFile = "C:\mssql\export\$($Row[0]).csv"
$command.CommandText = $queryData
$command.Connection = $connection
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $command
$DataSet = New-Object System.Data.DataSet
$SqlAdapter.Fill($DataSet)
$connection.Close()
$DataSet.Tables[0] | Export-Csv $extractFile -NoTypeInformation
}
It turned out to be this: $server = "SERVERNAME". Not this: $server = "SERVERNAME\INSTANCE"
After I incorporated these changes, everything worked fine.
