2  * DDBC - D DataBase Connector - abstraction layer for RDBMS access, with interface similar to JDBC. 
3  * 
4  * Source file ddbc/drivers/mysqlddbc.d.
5  *
6  * DDBC library attempts to provide implementation independent interface to different databases.
7  * 
8  * Set of supported RDBMSs can be extended by writing Drivers for particular DBs.
9  * 
10  * JDBC documentation can be found here:
11  * $(LINK http://docs.oracle.com/javase/1.5.0/docs/api/java/sql/package-summary.html)$(BR)
12  *
13  * This module contains misc utility functions which may help in implementation of DDBC drivers.
