Question

I am writing a batch script which makes multiple calls to powershell scripts to carry out a few operations.
Ive tested out both scripts individually and they both produce the results I want, however when I combine them the powershell script hangs. I believe the problem comes from the fact that I have a php script which passes values to the batch file which then makes calls to different powershell scripts based on that information.

My Batch script makes this call:

echo Setting Up Database
powershell -noninteractive -File ".\setupDB.ps1 " %1 > nul
echo Done!

and my powershell script looks like this:

$tempname = #$args[0]
$dbname = "cw_" + $tempname

[void][System.Reflection.Assembly]::LoadWithPartialName("MySql.Data")
$dbusername = "username"
$dbpassword = "password"

echo "Creating connection to server"

$connStr ="server="myserver";Persist Security Info=false;user id=" + $dbusername + ";pwd=" + $dbpassword + ";"
$conn = New-Object MySql.Data.MySqlClient.MySqlConnection($connStr)
echo "Done"

$conn.Open()

if($conn.State -eq "Open")
{
echo "Connection open"
}

$cmd = New-Object MySql.Data.MySqlClient.MySqlCommand
$cmd.Connection  = $conn
$cmd.CommandText = "DROP DATABASE IF EXISTS " + $dbname
$cmd.ExecuteNonQuery()

$cmd.CommandText = 'CREATE DATABASE `' + $dbname + '`'
$cmd.ExecuteNonQuery()

$conn.Close()
if($conn.State -eq "closed") {
echo "closed connection"
}
exit

When I pipe the results from my powershell script to file I can trace that the entire script runs the way I expected, however after that it does not return to my batch script to continue running the rest of my scripts.
Any help would be greatly appreciated.

echo Setting Up Database
CALL powershell -noninteractive -File ".\setupDB.ps1 " %1 > nul
echo Done!

Try this. The call statement starts the PowerShell as sub-process and after it’s finished control is returned to the original script.
