Pass multiple parameters to sqlcmd from powershell

Due to some nasty bugs in invoke-sqlcmd wrapper in powershell we must use the following workaround to be able to pass multiple parameters/variables to sqlcmd.exe from powershell

$parameterizedCmd = 'sqlcmd -b -E -I -S . -d master -i "script.sql"'+
' -v Parameter1="'+$PsParameter1+'"'+
' -v Parameter2="'+$PsParameter2+'"'
write-verbose $parameterizedCmd 
# invoke-expression and invoke-sqlcmd are insanely bugged
# workaround by executing via cmd /c instead
& cmd /c $parameterizedCmd
