$ dpkg -l | grep mysql
ii libdbd-mysql-perl 4.016-1 Perl5 database interface to the MySQL database
ii libmysqlclient16 5.1.49-1ubuntu2 MySQL database client library
ii mysql-client-5.1 5.1.49-1ubuntu2 MySQL database client binaries
ii mysql-client-core-5.1 5.1.49-1ubuntu2 MySQL database core client binaries
ii mysql-common 5.1.49-1ubuntu2 MySQL database common files, e.g. /etc/mysql/my.cnf
ii mysql-server-5.1 5.1.49-1ubuntu2 MySQL database server binaries and system database setup
ii mysql-server-core-5.1 5.1.49-1ubuntu2 MySQL database server binaries
ii mysql-testsuite 5.1.49-1ubuntu2 MySQL testsuite
(It's the resulting set of packages that were installed by doing apt-get install mysql-server-5.1 mysql-testsuite.)
