Question

EDIT

This query is not working, any idea why?

select `key`, distinct `filename`, `url`, `processed`, `timestamp` from snaps;

It says to check syntax near 'distinctfilename“

---

I have the following table

CREATE TABLE IF NOT EXISTS `snaps` (
  `filename` varchar(255) COLLATE utf8_bin NOT NULL,
  `url` text COLLATE utf8_bin NOT NULL,
  `processed` int(11) NOT NULL,
  `timestamp` int(11) NOT NULL,
  KEY `key` (`key`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_bin;

I exported the rows of the table and mistakenly imported it back into the same table. So now I have two rows of everything. filename is unique.

How can I delete the duplicate records?

Answer 1

SELECT DISTINCT into a temporary table, flush the first one, and move them back again.
