Tables Using BDB Storage Engine in MySQL

Q

How To Create a New Table Using the BDB Storage Engine in MySQL?

BDB (BerkeleyDB) storage engine was originally developed at U.C. Berkeley. It is now maintained by Sleepycat Software, Inc., which is an Oracle company now. BDB is transaction safe, and has been used in products from many companies, like Cisco Systems.

BDB is not the default storage engine. You need to specify "ENGINE = BDB" at the end of the "CREATE TABLE" statement to create new tables with the BDB storage engine. The tutorial exercise below shows you a good example:

>cd \mysql\bin
>mysql -u dev -piyf fyi

mysql> CREATE TABLE fyi_bdb (
  id INTEGER PRIMARY KEY,
  title VARCHAR(80), 
  count INTEGER )
  ENGINE = BDB;
Query OK, 0 rows affected, 1 warning (0.07 sec)

mysql> SHOW CREATE TABLE fyi_bdb;
  CREATE TABLE `fyi_bdb` (
  `id` int(11) NOT NULL,
  `title` varchar(80) default NULL,
  `count` int(11) default NULL,
  PRIMARY KEY  (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 
1 row in set (0.02 sec)

mysql> drop table fyi_bdb;
Query OK, 0 rows affected (0.00 sec)

The "SHOW CREATE TABLE" command reports that table "fyi_bdb" was actually created with the MyISAM storage engine. This is because the BDB storage engine is not included in the default "mysqld" configuration.
