inno setup installing sql server 2005 and after updating database - sql-server-2005

Question

I want to use silent install of sql server 2005 express and after I want to update database. I used inno setup script wizard and I selected SQLEXPR.exe as installing application and the sql file which I want to update database after installing the sql server 2005 express."emin.sql" is a file that I want to update database after installing sql server.
Here is my code which is generated by wizard;

#define MyAppName "My Program"
#define MyAppVersion "1.5"
#define MyAppPublisher "My Company, Inc."
