MySQL wrapped 连接池

1. http://www.alhem.net/project/mysql/

After pounding away miles of code using the C API of MySQL in my applications, I finally managed to put together a simple and naive C++ wrapper. The wrapper consists of two classes, one session control object ("Database") and one worker object ("Query"). The session control object contains a simple connection pool, so established database connections are reused in a sane manner. The worker object contains methods to execute sql queries alternatively store results from sql queries.

SQL Relay

SQL Relay is a persistent database connection pooling, proxying and load balancing system for Unix and Linux supporting ODBC, Oracle, MySQL, PostgreSQL, Sybase, MS SQL Server, IBM DB2, Firebird, SQLite and MS Access (minimally) with APIs for C, C++, ODBC, Perl, Perl-DBI, Python, Python-DB, Zope, PHP, Ruby, Ruby-DBI, Java, TCL and Erlang, drop-in replacement libraries for MySQL and PostgreSQL clients, command line clients and extensive documentation. The APIs support advanced database operations such as bind variables, multi-row fetches, client-side result set caching and suspended transactions. It is ideal for speeding up database-driven web-based applications, accessing databases from unsupported platforms, migrating between databases, distributing access to replicated databases and throttling database access.
