A Simple and Smart ODBC Wrapper Library

Direct usage of ODBC is very complex. Anybody who tries to work with ODBC will agree with this statement. This small and smart ODBC wrapper makes working with ODBC much simpler.

Environment:
  • Microsoft Visual C++ 6.0/SP4
  • ODBC 3.0 or above
  • Microsoft Windows 95...XP

    Direct usage of ODBC is very complex. Anybody who tries to work with ODBC can say it. Also, ODBC is a function-level interface. It is a good universal interface, but all structured C++ applications look very horrible when plain ODBC calls are used.

    I want to offer a little library, which:

    • Wraps access to ODBC into a set of classes
    • Wraps processing of ODBC and usage errors into an exception mechanism
    • Doesn't use any external libraries, including MFC and ATL
    • Doesn't require any special conditions to use it
    • Automates column binding operations
    • Can automate (for MSSQL server) binding of parameters
    • Can provide transparent work with LOB columns/parameters without limitation of their size
    • Has a Help file, even if this Help file is simple
    • Is freeware, open-source library
    • Supports powerful local-side cursors with indexing and modifying of cursor(insert, update, delete) are supported

    I sought such a library for some years, but I didn't find a library that conforms to all these conditions. Because I have used ODBC in many projects, some classes were developed some time ago. Now I have refined these classes. And I hope that these classes can help somebody.
