View 1 RepliesDataSource Controls :: How To Make One DataContext For Multiple Databases
Apr 17, 2010I have 2 databases one called DB1, and the other DB2. Both of them has exactly the same design (tables, procedures and etc..)
Now, I am using SQLMETAL to create the DataContext. problem is that there are two lines that direct to a certain database and so I cannot use the same code for both databases.
here is the code:
[Code]....
Now, What I am lookin for is a programmatically way to change this two lines (DataBaseAttribute and the connrection string) .
The easiest solution for me of course is to create the class twice, with the same code and just change manually what I need which is not what I am looking for.

DataSource Controls :: How To Handle Membership Info Among Multiple Databases
May 13, 2010I'm creating a site that will offer several different services (blogs, videos, images..), all under the same site.
Each service will use a separate database and all services must use the same membeship info. Users will only need one login to access all these services.
For the membership database i will use the default aspnetdb database.
There are two ways i can think of:
1) Use a join-query between two databases, each time i want to show some service records per user.
2) Create a custom membership-info table in each service's database, and keep it in sync with the master membership table in aspnetdb database.
The custom membership table will be like this:
Id - int, primary, identity
UserId - uniqueidentifier (of aspnetdb database)
What is the best way to do this in the long run, when i will have six or seven or more services ?

Any way to connect to the Oracle server like in SQL Server we do ??

View 2 RepliesSQL Server :: Connect To Two Databases?
Sep 24, 2010I've had a site up and running for quite some time with "ASPNETDB.MDF" as database. I recently got a request to make a second site with it's own database, but that also includes a admin interface to manage the first site's database.
"Fine", I thought. "I'll just add a new connection string and point to the first database.". But unfortunately it seems to involve a few more steps then that.
My connection strings are:
<add name="ASPNETDBConnectionString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|ASPNETDB.MDF;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>
<add name="myfirstsite_ASPNETDBConnectionString" connectionString="Database=myfirstsite_aspnetdb;Data Source=.SQLEXPRESS;AttachDbFilename=C:\Inetpub\myfirstsite\App_Data\ASPNETDB.MDF;Integrated Security=True;User Instance=True" pro
But whenever I start up my first website I can't access the database through my second one. I just keep receiving the error: "Cannot open user default database. Login failed. Login failed for user 'MYCOMPUTERWEB01ASPNET'."
And if I were to start up my second one first I can do what I want, but then the first site would get the same error. So I guess the error is somehow related to the database already being in use.
