Executing scripts on MSDE

Hi all,
How do we run a script from a file if we have only MSDE installed and there are no client tools installed? What exactly I want to know is, say I'm distributing my application and am not very sure whether they have SQL Server installed or not (and for trial purposes nobody would buy a license ). So in that case I want to run the script from InstallShield to create database, tables, procedures and triggers which are written on a file. Currently I can do that with isql prompt in a command window. But with MSDE we don't have the isql tool installed. So, how do I run the script then?

Thanks.

Just on top of my head, you can write a small executable that opens a dsn-less connection to the db and runs the script, or you can think about switching to an opensource database, like Firebird or PostgreSQL.

Thanks, but I need to connect through DSN b'cos I'm using a third party tool which essentially uses DSN. Moreover, that won't help you in creating your database. Your soln will work only if we already have a database, but I am going to create database through a script only.

so what? create it, it's in the registry
this does not prevent a dsn-less connection to the database from working, an example of a create database query can be found here
not, but even in that case you could add an empty database (detached) and attach it running the appropriate sp.

I think, I'm not putting my problem properly.
1. I have an installation file (made through InstallShield) wherein I open up the DOS window, and then execute the isql statement (isql /U "+username+ " /P "+ password +" /S"+ <machine where database to be installed> +" /n"+" -iscriptfile.sql". My scriptfile.sql contains all the sql statements right from creating database to tables, procedures and user logins.
2. Now, I want to be able to do the same on the MSDE. Can I do this? If yes, how and if not, why not?

My other exe then connects to this database which has been so created through a DSN. So, creating a DSN is not a problem.
