ProjectPage SqlWrapperXX
SqlWrapperXX is a C++ library that encapsulates various SQL APIs into a single, uniform interface. It supports MySQL, PostgreSQL, Sqlite2 and Sqlite3. SqlWrapperXX is designed to be easy to use, small, and to the point.
SqlWrapperXX should be especially useful to people that aren't comfortable with the APIs of the database engines, since it's very easy to use correctly. As a trade-off it doesn't have all the bells and whistles of some of the larger libraries, but for applications with relatively straight forward database requirements it should do the job.
