Create Database ADO.NET

M

Mark Moore

This seems like the most newbie question, but I can't find
the answer after 1/2 a day searching.

How can I create a new database on a (MSDE) SQL server
from .NET?

Here's the code I use, but it looks like ASPNET doesn't
have permission to create a new database.

{
SqlConnection myConnection = new SqlConnection
("Integrated Security=SSPI;Server=
(local);Database=rescopa");
SqlCommand cmd;

try
{
myConnection.Open();
}
catch ( SqlException e )
{
if ( e.Number != 4060 &&
e.Number != 911 ) throw
e; //BUGBUG: How does SqlException select for specific
errors?

SqlConnection conn2 = new SqlConnection
("User ID=sa;Server=(local)");
conn2.Open();
cmd = new SqlCommand( "CREATE DATABASE
rescopa", myConnection );
cmd.ExecuteNonQuery();
conn2.Close();

myConnection.Open();
}
}

Damn! I knew I was too quick on the trigger with the
previous post...

The code I posted had some mods I was trying that didn't
work. Here's the code that I meant to post followed by
the response I get from the IIS server when I execute the
CREATE DATABASE command:

-----------code---------------
{
SqlConnection myConnection = new SqlConnection
("Integrated Security=SSPI;Server=
(local);Database=rescopa");
SqlCommand cmd;

try
{
myConnection.Open();
}
catch ( SqlException e )
{
if ( e.Number != 4060 &&
e.Number != 911 ) throw
e; //BUGBUG: How does SqlException select for specific
errors?

SqlConnection conn2 = new SqlConnection
("Integrated Security=SSPI;Server=(local)");
conn2.Open();
cmd = new SqlCommand( "CREATE DATABASE
rescopa", conn2 );
cmd.ExecuteNonQuery();
conn2.Close();

myConnection.Open();
}
}

MSDE (as you have discovered) is NOT a development tool--it's a SQL Server
engine to be used during deployment. Get a copy of SQL Server Developer
Edition ($49). It has the full toolset needed to create databases and manage
the tables, users, views, stored procedures, triggers and most importantly,
the permissions.

Bill,

Thanks for the tip (I just bought a copy), but... This
still doesn't help me with my problem.

I'm developing a website that will be deployed to servers
that are running MSDE. When I'm bootstrapping the
database (before it exists), I would like to create a
fresh, empty database.

How do I do this programmatically?

That's pretty easy. Simply execute (fill in your own name and filenames) the
following script on the Master database.
CREATE DATABASE Sales
ON
( NAME = Sales_dat,
FILENAME = 'c:\program files\microsoft sql
server\mssql\data\saledat.mdf',
SIZE = 10,
MAXSIZE = 50,
FILEGROWTH = 5 )
LOG ON
( NAME = 'Sales_log',
FILENAME = 'c:\program files\microsoft sql
server\mssql\data\salelog.ldf',
SIZE = 5MB,
MAXSIZE = 25MB,
FILEGROWTH = 5MB )
