RE: [PHPwestoz] [OT] MySQL UNIQUE INDEX

["Mark Hendley" <mh@cynergic.net>]

Heh. My first post is giving info - go figure :)

Try:

CREATE TABLE library (
 ID INT UNSIGNED NOT NULL AUTO_INCREMENT,
 Filename TEXT NOT NULL,
 Artist TEXT NULL,
 Title TEXT NULL,
 Album TEXT NULL,
 FID TEXT(40) NOT NULL,
 PRIMARY KEY ID (ID),
 INDEX UID (FID(40))
) TYPE = MyISAM COMMENT ='';

The manual reference you want is
http://dev.mysql.com/doc/mysql/en/indexes.html

:) - took me longer to find the reference than answer the question.

Cheers

Subject: [PHPwestoz] [OT] MySQL UNIQUE INDEX

I know this isn't PHP but hopefully one of you guys will know the answer

(and it is for a PHP project)
I am trying to create a table that has a primary key and a unique key 
based on different columns.
The query is:
CREATE TABLE library (
 ID INT UNSIGNED NOT NULL AUTO_INCREMENT,
 Filename TEXT NOT NULL,
 Artist TEXT NULL,
 Title TEXT NULL,
 Album TEXT NULL,
 FID TEXT(40) NOT NULL,
 PRIMARY KEY ID (ID),
 INDEX UID (FID)
) TYPE = MyISAM COMMENT ='';
And the error is:
ERROR 1170 (42000): BLOB/TEXT column 'FID' used in key specification 
without a key length
I can't find anything in the manual that tells me how to get around
this.

Thanks

Tim
