Automating the creation of a database

Hi;
We have a program (ASP.NET) that requires a database as it's back end. We
are trying to create an install that requires as little expertise as
possible. In other words, no DBA required.
For creating the database itself we are at that point. We use the registry
to find the location of osql.exe and use that to run the schema that creates
the database. I'ld prefer an API we could call so we can more cleanly handle
errors but this works fine 98% of the time.
The remaining problem is ownership of the created database.
1) Is there a way (in .NET 2.0) to query if the database is mixed mode
authentication.
2) And if it is a way to both get a list of all users
3) And to create a user?
We can already enum all domain users. So with the above we could give them a
list of all users they can choose from as the owner and also let then create
a new one - without the user ever having to run any SqlServer tool or even
have any installed.
thanks - dave

It is SERVER property not a databases
SELECT SERVERPROPERTY('IsIntegratedSecurityOnly
') AS
[IsIntegratedSecurityOnly]

> 2) And if it is a way to both get a list of all users
EXEC northwind..sp_helpuser

> 3) And to create a user?
Create Database mydb
go
use mydb
go
sp_addlogin 'mydbuser','monitor','mydb'
go
sp_adduser 'mydbuser'
go
sp_Addrolemember 'db_datawriter','mydbuser'
go
sp_Addrolemember 'db_datareader','mydbuser'
go

>|||Hi David,
I am afraid that the database may have some synchronous problem now. Our
yesterday's replies cannot be seen from Web and we also cannot see your
replies.
So I post it again from Outlook Express and hope you could see it now. Sorry
for bringing you any inconvenience.
I understand that your application used osql.exe to create the database and
you have three questions on the ownership of the created database now:
1. How to query (in .NET 2.0) if the database is with mixed authentication
mode?
2. How to get a list of all users?
3. How to create a user?
If I have misunderstood, please let me know.
For your three questions and even your creating database function, you can
fully resolve the questions by using the SQL Server SMO component for .NET
2.0.
1. You can just create a Server object like this:
//Server Name
string strConn = "(local)";
//Instantiate SMO Server Object
Server svr = new Server(strConn);
Console.Writeline(svr.Settings.LoginMode.ToString());
2. To get the list of all users, you can use:
Database db = server.Databases["your_db_name"];
UserCollection users = db.Users;
3. To create a user, you can use:
//Instantiate SMO Login object
Login l = new Login(svr, loginName);
//If Login doesn't already exist
if (!svr.Logins.Contains(loginName))
{
//Login should be of type Sql Login
l.LoginType = LoginType.SqlLogin;
//Create the Login on the SQL Server with password: pa$$w0rd
l.Create("pa$$w0rd");
//Add the login to the sysadmin role
l.AddToRole("sysadmin");
}
//Instantiate a new database object
Database db = new Database(svr, "Fizoo2");
//Make SQL Server create the database
db.Create();
//Instantiate a new User object
User u = new User(db, "SQL_Login_user");
//associated it with the login "SQL_Login"
u.Login = loginName;
//Make SQL Server create the user
u.Create();
