Dbc

This library is out of date. Since I've updated this web page, I've upgraded several versions of Linux and g++. I've continued to update dbc, but have not made it public. Current version uses unixODBC and PostgreSQL. Oracle support is probably stale; I havn't used it in ages. Drop me a line if you're interested in the latest code. Now back to old, out-of-date html...

Dbc is a portable, extendable database access class library which currently supports Oracle8 OCI and ODBC. I have attempted to make the library as easy to use as possible, while remaining flexible and fast. The library allows portablility but does not enforce it; it makes no attempt to prevent usage of database specific functionality.

All development is being done on Linux (RH5.1) with Egcs 1.1. The code uses C++ exceptions, STL and templates, so older compilers will have problems. Egcs 1.0 may work, although I've had trouble with it's exception support. g++ 2.7.x will not work.

Dbc...

• Supports Oracle 8 OCI and ODBC. OCI has been tested with the recently released Oracle 8 for Linux. ODBC support has been tested with Solid Server and MySQL (using iODBC).
• Supports array fetches.
• Supports array inserts/updates (OCI only).
• Seems to be pretty fast and simple to use.

Applications

Well, there's one anyway. Take a look.

Availability

Dbc is being made available under the terms of the GNU Library General Public License.

You can download libdbc from here (85K).

You can look at the doxygen generated documentation here.

To build you will find tmake helpful.

Notes for v0.4

To build:

• Currently OCI and ODBC support are compiled in. You will need Oracle 8 with current patches and Solid Server if you want to use both. Modify libdbcimpl.h if you would like to eliminate support for either.
• If you would like to use MySQL instead of Solid Server, you will have to tweak odbchdr.h to cause the MySQL includes to be compiled in rather than the Solid Server includes. If you want to try to add support for another ODBC library, all you should have to do is add the headers to odbchdr.h.
• Modify the tmake template libdbc.pro. The INCLUDEPATH variable will have to be set appropriately on your system. By default it is set to the locations of the Solid and Oracle header files on my system. It is not necessary to compile against both; either can be used, or you can attempt another ODBC library. When you're done modifying libdbc.pro, regenerate the makefile by running 'tmake -o Makefile libdbc.pro'. If you do not have tmake, you will have to edit the Makefile manually (or you can download tmake from this site).

To install:

Copy the libraries to your favorite local library spot (/usr/local/lib perhaps) and copy dbc*.h to your favorite local include spot.
