. NET platform Web Application Deployment (database installation and automatic configuration)

It is convenient to deploy Web solutions on the. NET platform. We can use Visual Studio. NET 2003 to add a web installation project and add the project's main output and content files in the deployed "File System Editor", which is easy to install. Program .

   However, the installation program created in this way only includes the web page and ASP. install the DLL files compiled by the net program to the IIS Directory of the target machine. This is acceptable for general applications (for example, the ACCESS database can be packaged into the installer together ); if the database is SQL Server, you need to install the database at the time of deployment. The creation of the installation program will be more complicated. You need to customize the installation program class. Execute the SQL script in the installer class and write the connection string to Web. config.

   L Install Database

Microsoft msdn introduced how to create a database when deploying an application. For example:

Http://msdn.microsoft.com/library/default.asp? Url =/library/en-US/vsintro7/html/vxwlk1_throughusingcusTomactiontocreatedatabasEduringinstallation. asp

This method creates an installer class and calls ADO. net in the installer class to execute an SQL statement (the SQL statement is placed in a text file) to create a database.

   However, this method has a problem. If SQL Server2000 is used to generate a script file for all table creation, views, and stored procedures, ADO is used. net to execute this script file, it will be because the script contains many "go" statements and errors. Of course, we can replace "go" with a line break and use ADO. Net to execute SQL statements one by one. Obviously, the efficiency is relatively low.

 

The best way is to call osql to execute the script. (Or create a CMD file for a database project, and the CMD file also calls osql when creating a database ).

 

First, create an ASP. NET web application, http: // localhost/vbnettest, and open the vbnettest project.
