RapTier is a template-based ASP.NET, C#, VB.NET and SQL code generator that creates robust database driven applications for a wide range of databases. It is an easy-to-use tool that significantly reduces development and testing time as well as improves the quality and performance of your code.

The main benefit from using RapTier is enormous saving of development and testing time. RapTier generates thousand lines of code in a matter of seconds. The generated code meets the highest standards of coding practices. It is pre-tested, clean, well-structured and fully documented. Our development team worked hard on optimizing and testing the generated code.

• Generate Data Access Tier
• Generate ready-to-use ASP.NET database-driven applications
• Generate fully-functional WinForm database applications
• Document your database

The code generator currently supports C# and VB.NET. You can access the generated compiled DB-tier classes from any .NET compatible language.

RapTier should work with any database that has an OLEDB provider. The tool has been tested with MS SQL Server, MSDE, MySQL, Oracle, MS Access, FoxPro, Sybase SQL Anywhere, and Sybase ASE.

We tested RapTier on Microsoft XP and 2000. However, the application should run on any Microsoft platform with installed .Net Framework. The generated code can run on all .Net platforms including MONO.

The machine on which you install RapTier must meet the following system requirements:

• Installed the MS .Net Framework 1.0 or higher
• 5 MB of available space on hard drive

Yes, you can customize the generated code to meet your needs. Simply add your code to classes specifically designed to save all user changes. Please check the RapTier documentation as well as the "Template and Code Customization" section of the forum for more details.

Yes, you can do that. Please check the "Creating RapTier Templates"article as well as the documentation for more details.

RapTier is available in three editions: RapTier Lite (FREE), RapTier Professional, and RapTier Enterprise. RapTier Professional is priced at $299 per developer. RapTier Enterprise lists at $499. All editions include free support and free upgrades for minor versions. Volume discounts are available.

No, we provide FREE support for all our products.

Yes! The Enterprise edition of RapTier generates stored procedure wrapper methods that significantly simplify code, which is needed to execute stored procedures.

RapTier 1.4 and higher includes a special DB2 schema loader, which is used when one connects to a DB2 database using the standard ibmdadb2 OLE DB provider.

The only reason DB2 is not in the list of the supported databases is because this IBM OLE DB provider has some difficulties recognizing '?'s in SQL statements. It can be fixed by switching to a different provider (native .NET, ODBC, or another OLEDB) after the code is generated.


The DB Documentation template generates documentation for any database that RapTier can load including DB2.

If you got this error using the generated WebForm UI, then most likely when you created the RapTier project you connected to the database using the Windows authentication.
While both RapTier and WinForm UI run under your Windows account, ASP.NET utilizes a special account that usually does not have database access rights.

To resolve this problem use one of the following solutions:
- Switch to the user name/password authentication (simply edit the connection string in the <DatabaseName> class)
- Add the ASPNET Windows user to the list of the DB users
- Use impersonation (see MSDN for details).

Also you may have this error if you checked "Generate Stored Procedures" but did not add the generated stored procedures to your database.
