Hello,
I have a questions and I hope, that is possible in MySQL.
I have the following short Table.
CREATE TABLE IF NOT EXISTS `testtable` (
`id` bigint(20) unsigned NOT NULL auto_increment,
`id-crc` bigint(20) unsigned NOT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `id-crc` (`id-crc`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
`id` is the unique autoincrement
in `id-crc` I would like save the CRC32 from `id` (the coloumn is unique)
E.G.
id id-crc
--------------------
1 2212294583 --> CRC32('1')
2 450215437 --> CRC32('2')
3 1842515611 --> CRC32('3')
I would like insert the CRC32 directly when I make a new Insert. E.G.
INSERT INTO `db283796092`.`testtable`
(
`id` , `id-crc`
)
VALUES (
NULL , LAST_INSERT_ID()
);
But LAST_INSERT_ID() is 0!!!! How can I make that, that he use the actual
INSERT-ID?
Best regards
Thunder
