How to connect to Firebird from C++


There are several options.

1. ODBC - this should be your last option if nothing else works. Firebird ODBC drivers mostly work, but do some testing with various datatypes before you go into it. No access to Firebird API.

2. Use the C API directly. This approach is fastest, but also error prone. Documentation for C API is not very user friendly, and sometimes you'll need to ask questions at support lists.

3. Use some C++ wrapper:


3.a. Many have reported great success with IBPP. It's a mature open source project with a lot of users (administration tool FlameRobin for example). IBPP is very clean and easy to use C++ library. Supports all Firebird functionality, Services API, etc. Works on Windows, Linux, Mac OS X, FreeBSD, Solaris, and probably all other Firebird supported platforms. Actively developed and maintained.

3.b. DatabaseLayer

DatabaseLayer provides a JDBC-like interface to database I/O. So far only SQLite3, PostgreSQL, MySQL, Firebird, and ODBC database backends are supported. MiniCppUnit unit tests are used to make it easier to add more database backends in the future. It is built upon wxWidgets, so it can be an interesting choice if you develop wx applications.

3.c. SOCI

Open Source, Boost license. Supports Oracle, PostgreSQL, Firebird, MySQL, SQLite, MS SQL Server (via ODBC).

3.d. SQLAPI++

If you aim for cross-platform support with multiple database systems (Oracle, MSSQL, Postgres, ...) there is a commercial SQLAPI++ library. We haven't had time to play with it yet, as we're only interested in Firebird support and IBPP works like a charm.
