Connecting Two Different Databases
Jan 9, 2005
Hi,
Is there a way to connect to two separate databases at the same time through my web application?
In my web.config under the configuration/appSetting I have created two keys for database connection:
<add key="MyConn" value="server=PLMNBKPLMNBKSQLSERVER;uid=sa;pwd=xxxx;database=SourcingDB" />
<add key="MyConn2" value="server=PLMNBKPLMNBKSQLSERVER;uid=sa;pwd=xxxx;database=SeaTender" />
This enable me to pass the connection string to a session variable through a dropdownlist box and connect to the desired database.
However, I would like to create a dataset from two tables which are not in the same database, one in the "SourcingDB" and the other one in the "SeaTender".
Thanks for some guidance.

Hey everyone. I am somewhat of a newbie to the database world.
I have been given the task of connecting two different SQL databases. Both are Microsoft SQL.
I want some of the tables of one of the databases to be linked to the tables of the other.
Is this possible?
Thanks

Hi everyone.
I need to know which are the best ways to connect to a remote SQL SERVER 2000 from inside a VB6 application. By remote I mean on a dedicated server outside my LAN that I can access by IP address.
Any opinion would be appreciated.

I am running the queries directly from the 2005 Mgt window to take as many variables out of the equasion. I get the same error in Visual basic

I have moved my databases to 2000 to instance of 2005 on the same server.
Now i set databases offline in 2000 as i did upgrade use backup & recovery method.
& my connection string
Password=test;Persist Security Info=True;User ID=test;Initial Catalog=databasename;Data Source=ipaddress
i was using above connection string to connect when using 2000 databases form applications in the production machine
I get the following error when i am running my applications now after moving to 2005
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
IS it because i have two server on one server or
What do i need to do in order to fix this....tried several thing by searching nothing worked out..
Let me know
thanks

Dear Readers,Is it possible, like in Access, to link to tables in other SQL databases that are on the same server? I have a query that I originally had in Access that queered from multiply databases. It did this by having those other tables in the other databases linked to the database that had the query.

I just restored my SQL server 2000 database on the SQL server 2005. after this i ran the Service broker sample ("Hello World") on this database by changing the AdventureWorks name to the new database name. The "setup.sql" runs fine. When i run the "SendMessage.sql" i was not getting any rows in the output (The message was not getting inserted into the queue). I checked the Service broker is enabled on this databased using the query "select is_broker_enabled from sys.databases where name = 'newdbname' " It was 1. I even tried the ALTER DATABASE SET ENABLE_BROKER. but it didnt work.
When i tried the sample on a newly created database it worked fine.
Is there any solution to make the restored database to work for service broker.
Thanks

I have a database that is currently connected and working properly in My SQL Server Management Studio. The problem I am havings is when I open My ASP.net 20 and Look in my Server Solutions I can not find the database to connect to it . It seems to be trying to use SLQ Express and not my SLQ Server Management Studio. How do I get my database to connect in my application? All I can see from within the Server solutions in ASP is the database .bak file which is the backup of the database. I thank you in advance.

Hi,
I am trying to connect to a SQL 6.5 database with VB.NET.
Is this possible, and if so, what kind of connection string is used and what mode of data access (OleDB, ODBC, etc.)
I have had several problems doing this and I am starting to wonder if there is anything special that needs to be done or if it is even possible. Thanks in advance!

I am trying to connect through a wan over TCP/IP to a SQL Server v.6.5 sp5a.
I am not logging into the domain, I am just trying to connect via ODBC. I keep getting an error 1326
which when I look in TechNet or MSDN refers to problems with Named Pipes. I have
TCP/IP configured for port 1433, Named Pipes, and Multiprotocol support all configured on the server.
Should I remove the Named Pipes support, or is that not the problem?

Hey everyone. I'm having some serious problems connecting to my database. I've pretty much bugged my server admin to death and I still can't connect to it. I've tried almost all the programs out there as well as http://www.aspenterprisemanager.com. I've probably spent a good 12 hours on this task (im trying to put MaxWebPortal on my site) and I'm going to ask for help. This is what my admin gave me for the SQL db:
Database Name: S5464_sehs
SQL Server: mssql4.uplinkearth.com
ODBC DSN: S5464_sehs
Username: sehs.us
Password: **********
Would anyone be able to help me to connect to this?

Hey all! I am new in this form and also new with the SQL serve. I have installed that free express edition of SQL server 2005 and when i am trying to connect to server from my C#.net application i am not able to do it and the error i am getting is the user is not SQL thrusted user. I am able to connect directly thru SQL server using this userid and password but not thru C#.net application.
I have read online that so many people are having that problem. so is it the problem of swl server Express edition or do i have to make some setting to connect to the application.
Please please please please someone guide me . I am stuck here in the beginning only. I would really appreciate it.
the code that i wrote is here:----
using System.Data.SqlClient;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
}
}
protected void Submit_Click(object sender, EventArgs e)
{
String querry;
SqlDataReader dbread;
try
{
SqlConnection conn = new SqlConnection(ConfigurationSettings.AppSettings["Conn1"]);
SqlCommand comm = new SqlCommand();
conn.Open();
querry = " Select password from login where userId='" + TxtUser.Text + "'";
comm.CommandText = querry;
comm.Connection = conn;
dbread = comm.ExecuteReader();
dbread = null;
if (dbread.HasRows)
{
while (dbread.Read())
{
if (dbread["password"].ToString() == Txtpwd.Text)
{
Response.Redirect("home.aspx");
}
}
Response.Write("Your Password Doesn't Match");
}
else
{
Response.Write("Your User Name Is Wrong");
}
conn.Close();
}
catch (Exception ex)
{
Response.Write(" This is an Error - " + ex.Message );
Response.End();

When I look at the connection string it's:
Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\ProcBuilder.mdf;Integrated Security=True;User Instance=True
This works fine on my machine, but when I try to run it on another computer it tells me:
"An error has occurred while
establishing a connection to the server. When connecting to SQL Server
2005, this failure may be caused by the fact that under the default
settings SQL Server does not allow remote connections."
It should not be trying to connect remotely, it's a local DB. Do I
have to install SQL Express on the machine I'm installing this on for
it to work?

My host sent these instructions, think they will work?
To access your SQL Server you can use your choice of database management software, including Microsoft Access, Visual InterDev, or the SQL Enterprise Manager.
If you are using Microsoft Access or Visual InterDev you will be connecting to the SQL Server via an ODBC connection, which requires you to make a Data Source Name (DSN) on your local computer.
If you have a Microsoft Access database, and you use the Microsoft SQL Upsizing Wizard to export your database into SQL, the Upsizing Wizard will assist you in the process of creating your ODBC connection.
To create a SQL DSN:
1. Log on to your hosting account's control panel at http://sahcinfo.org/admin 2. Click "Database Connectivity."
3. Choose "Create DSN."
4. Choose "Microsoft SQL Driver" from the Type drop-down list.
5. Enter a name for your DSN in the DSN field. It can be anything you want it to be, such as "Orders" or "MyDatabase." The Filename field is not required for SQL.
6. In the SQL IP Address field, enter the SQL Server name.
7. Enter your SQL user name in the SQL User Name field.
8. Click Submit.
To access the SQL Server using the SQL Enterprise Manager:
1. Open your SQL Enterprise Manager software. This is not supplied by Web.com.
2. Right-click on "SQL Server Group", then select "New SQL Server Registration"
3. Once the dialog box is open, fill in the fields. In the server field, type in your SQL Server name.
4. Type in the login information with your username and password.
5. Once all the information is entered click "Register." This will make contact with our SQL Server, and you will be able to add tables, manipulate your information and work on your database as you wish.
Please note that Web.com Technical Support will only troubleshoot connectivity to the SQL database, and cannot support issues with third-party software.
Web.com has also created a SQL 2000 User Guide to walk you through the process of setting up your account and database connections. To view or print it, go to http://64.226.3.32/article.asp?article=14689&p=1001

I'm trying to connect to an SQL server, but I'm unable. It suggests this is because SQL server does not allow remote connections, and points me to the named pipes provider, error 40 Could not open a connection to SQL server.
I am running SQL express service pack 2 under Vista. I am a member of SQL administrators (set during installation).
Under the SQL Server Configuration manager, SQL server and Browser are running, the protocols for sqlexpress and the native client have enabled shared memory, named pipes, and tcp/ip.
I tried removing and creating a new database. Now it sits under the database Engine section of Management Studio Express, with a white circle on the database icon. When I try to connect to this database, using either windows authentication or sql server authentication, it fails.
What else is there to try? If there was a troubleshooting guide, that would be helpful.

Hey, all. I've mainly worked with MySQL databases before. I'm working on an (old) ASP page that uses this connection string:strConnect = "Provider=SQLOLEDB; Data Source=SQL1.MYDBSERVER.NET; Initial Catalog=...; User ID=...; Password=..."
It works fine on the production server, but the local copy fails if I try to access the Products page (which uses the database), with this error: Microsoft OLE DB Provider for SQL Server (0x80004005)[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied./html/products.asp, line 19Similarly, if I plug the connection info into Tools/Connect to Database in Visual Studio, I get: Connection failed:SQLState: '08001'
SQL Server Error: 17
[DBNETLIB][ConnectionOpen(Connect()).]SQL Server does not exist or access denied. Am I doing something wrong? Do I need more info from the hosting provider to connect remotely? Or is the database not accepting remote connections at all?Thanks in advance for your help!
