/**
 * JDBC Interface to Mysql functions
 *
 * <p>
 * This class provides information about the database as a whole.
 *
 * <p>
 * Many of the methods here return lists of information in ResultSets.
 * You can use the normal ResultSet methods such as getString and getInt
 * to retrieve the data from these ResultSets.  If a given form of
 * metadata is not available, these methods show throw a java.sql.SQLException.
 * 
 * <p>
 * Some of these methods take arguments that are String patterns.  These
 * methods all have names such as fooPattern.  Within a pattern String "%"
 * means match any substring of 0 or more characters and "_" means match
 * any one character.
