How to Build an ASP.NET Web Site Using DB2 Data with Visual Studio 2005 - Page 4
August 15, 2006
That Was Fast...
As you can see, creating this simple Web page was very quick. (The length of this article can be accounted for by the step-by-step documentation, which should allow even non-developers to successfully build the application outlined in this article.) Truly, this rapid application development experience is a result of the synergy between the Visual Studio 2005 IDE and the integration work that's gone into this environment for DB2 databases.
There's so much more for .NET developers who write applications for the DB2 platform to take advantage of. Stay tuned for my next article on this topic!
Addendum: Adding a DB2 Data Source to the Visual Studio 2005 Server Explorer
If you're familiar with the Visual Studio.NET 2003 support that DB2 UDB provides, you'll recall that .NET developers writing applications on the DB2 platform were required to work within the IBM Explorer. The IBM Explorer was functionally equivalent to the Server Explorer; however, there were no open interfaces into the Server Explorer in Visual Studio.NET 2003 by which DB2 UDB could leverage to provide some of the features unique to the DB2 UDB plug-in.
The architecture of Visual Studio 2005 changed such that there are now interfaces that let you develop applications that connect to DB2 UDB V8 and DB2 9 databases using the Server Explorer. This provides a more native experience for .NET application developers used to developing applications on SQL Server databases.
To add a DB2 database connection to your Server Explorer, perform the following steps:
Note: If you already have a database connection to the database that is to provide your ASP.NET Web site with data, you can skip this section.
1. Right-click the Database Connections folder in the Server Explorer and select the Add Connection option. The Add Connection dialog box opens:
2. Ensure that the Data source field points to the (.NET Framework Data Provider for IBM DB2) data provider so that the Server Explorer will use the ADO.NET data provider written by IBM specifically for DB2 UDB V8 and DB2 9 databases.
The DB2 ADO.NET provider is not the default provider shown in this field. To change the database provider to use the one for DB2, click Change and select the IBM DB2 option from the Data source box, as shown below. You should also ensure that the IBM DB2 Data Provider for .NET Framework is selected in the Data provider field, but this should be the default:
Note: If you plan to work frequently with DB2 database connections, select the Always use this selection check box so that, when you add another database connection, Visual Studio 2005 will automatically select the DB2 data provider.
3. Enter the server name and port number (separated by a colon) in the Enter server name field. If you are connecting to a local database, you can use the localhost alias for your workstation.
Depending on the version of DB2 that you are running your beta on, you can optionally click Refresh to automatically list all the databases configured to respond to DB2 network database identification requests and automate the process of entering the required information.
4. Enter your user account credentials in the User ID and Password fields. I recommend that you save these credentials in the connection string (they are encrypted) by selecting Save my password. Selecting this option makes application development more streamlined because you are not challenged to provide authentication details during subsequent access requests to the DB2 database.
5. Select the database name from the Select or enter a database name drop-down list, or enter the name manually.
Note: In this article, I chose to connect to the SAMPLE database that is shipped with DB2 UDB V8. If you don't have the SAMPLE database created on your workstation, you can create it now by entering the db2sampl command from a Windows-based command prompt.
6. Optional: You can use the Specify Connection Options and Specify Filtering Options sections to further customize your database connection. The options associated with these toggles are shown below:
The DB2 support for Visual Studio 2005 comes with a rich set of connection time and filtering options. For the purposes of this article, you can just accept the default values.
7. Test the connection using the Test Connection button.
8. Click OK.
After adding your database connection, the Visual Studio 2005 Server Explorer should look similar to this:
In the previous figure, you can see that I've expanded the
SAMPLE database connection object; below it is a connection object to a SQL
Server 2005 database. Notice the beside
this database connection object: all databases appear this way until you click
them to make the database connection.
