I use this method:
CREATE TABLE `web_directory` (
...
SELECT id
SELECT id
SELECT id
SELECT id
SELECT id
`id` int(8) unsigned NOT NULL auto_increment,
`parent` int(8) unsigned NOT NULL default '0',
`name` varchar(100) NOT NULL default '',
PRIMARY KEY (`id`),
KEY `name` (`name`),
KEY `parent` (`parent`)
);
FROM web_directory
WHERE name = 'Web Chess Viewers'
AND parent = (
FROM web_directory
WHERE name = 'Software'
AND parent = (
FROM web_directory
WHERE name = 'Chess'
AND parent = (
FROM web_directory
WHERE name = 'Abstract'
AND parent = (
FROM web_directory
WHERE name = 'Board Games'
AND parent = (
SELECT id
FROM web_directory
WHERE parent =0
AND name = 'Games'
LIMIT 1
)
LIMIT 1
)
LIMIT 1
)
LIMIT 1
)
LIMIT 1
)
LIMIT 1
What are the speed advantages of a web directory built from LDAP be
faster than SQL.
