SQL Server 2008 R2 Express unattended setup

Hello

I am installing SQL Server Express 2008 R2 using this script:

/q /ACTION=Install /FEATURES=SQL /SECURITYMODE=SQL /SAPWD=""my password""/INSTANCENAME=InspTools /SQLSVCACCOUNT=""NT AUTHORITY\Network Service""/IACCEPTSQLSERVERLICENSETERMS

I think the script is right! :)

I would also like the install to either execute a sql script to create a new database, or attached an mdf file.

I am not sure how to do that. Any help would be great!

I am using InnoSetup if that matters.
