Converting multiple lines of mysql string into predefined csv format? - mysql

Question

this is more like a how-to question about csv, excel, mysql files than a standard coding question. However I really would appreciat some help with this.
I have this predefined CSV format, that I need in order to import it to a database with Sequel Pro.
ID,"user_login","user_pass","user_nicename","user_email","user_url","user_registered","user_activation_key",user_status,"display_name"
1,"some_name","$P$BDMmGci3KAqNQwfPtgzfQTp8D3k7bC.","some_name","some.name#gmx.net","","2013-06-27 11:32:08","",0,"Some Name"
On the other hand I have an old database file looking like this …
CREATE TABLE `ezxsubscription` (
`id` int(11) NOT NULL auto_increment,
`version_status` int(11) NOT NULL default '0',
`subscriptionlist_id` int(11) default '0',
`email` varchar(255) default '',
`hash` varchar(255) default '',
`status` int(11) default '0',
`vip` int(11) default '0',
`last_active` int(11) NOT NULL default '0',
`output_format` varchar(255) default '',
`creator_id` int(11) NOT NULL default '0',
`created` int(11) NOT NULL default '0',
`confirmed` int(11) NOT NULL default '0',
`approved` int(11) NOT NULL default '0',
`removed` int(11) NOT NULL default '0',
`user_id` int(11) default '0',
`bounce_count` int(11) default '0',
PRIMARY KEY (`id`,`version_status`)
) TYPE=MyISAM;
--
-- Dumping data for table `ezxsubscription`
--
INSERT INTO `ezxsubscription` VALUES (454,1,5,'name#surname.com','31b6bde64e1282ba82d7d0c8ad6ebaa9',2,0,0,'2',1127,1142840848,0,1142840868,0,2633,0);
INSERT INTO `ezxsubscription` VALUES (1,1,5,'name.name#gmail.com','fff4b8d75ecdfad43ed8c89444939cfb',2,0,0,'2',10,1141956489,1141956489,1141956489,0,14,0);
…
The database has like 400 users in it that I couldn't sort by hand. I need to have the database file to be in the format of the predefined CSV above. Where the email-address should be the user_login and user_name. The rest of the old database like approved, removed or whatever can simply be disregarded. It's just about the user-login and the passwords.
Any clever idea on how to do so? The aim is to import all the old users of the old database to the new database (based on Wordpress).
I would really appreciate some tips or tricks.
Thank you in advance.
Matt
Update:
This is the old format of the ezxsubscription table.
"id","version_status","subscriptionlist_id","email","hash","status","vip","last_active","output_format","creator_id","created","confirmed","approved","removed","user_id","bounce_count"
1,1,5,"andreas#gmail.at","fff4b8d75ecdfad43ed8c89444939cfb",2,0,0,2,10,1141956489,1141956489,1141956489,0,14,0
All I wanna do now is convert this users to the new wordpress format:
"ID","user_login","user_pass","user_nicename","user_email","user_url","user_registered","user_activation_key","user_status","display_name"
1,"local","$P$BCf7QHr3rsp0YNZd7eMfYgncRZmR6j0","local","temp#local.dev","","2013-03-14 18:46:29","",0,"local"
I do even have problems understanding what the hash in the old db means.
All I wanna do is copy all existing old users to the new wordpress database so that I have the e-mail addresses and the passwords, so that they are able to login again.
So I want to make the old email the username of the new wordpress db. And the hash should probably be the new user_pass in wordpress. However I only hope that the hash is the password of the current login — I don't even know for sure.
Kind Regards,
Matt

Use SELECT ... INTO OUTFILE syntax to create a CSV file from your old table with a query like this
SELECT *
INTO OUTFILE '/path/to/your/file.csv'
FIELDS TERMINATED BY ',' ENCLOSED BY '"'
LINES TERMINATED BY '\n'
FROM
(
SELECT 'id', 'user_login', 'user_pass', 'user_nicename','user_email','user_url','user_registered','user_activation_key','user_status','display_name'
UNION ALL
SELECT id, email, hash, SUBSTRING_INDEX(email, '#', 1), email, '', created, '', status, SUBSTRING_INDEX(email, '#', 1)
FROM ezxsubscription
) q
Content of the created file:
"id","user_login","user_pass","user_nicename","user_email","user_url","user_registered","user_activation_key","user_status","display_name"
"454","name#surname.com","31b6bde64e1282ba82d7d0c8ad6ebaa9","name","name#surname.com","","1142840848","","2","name"
"1","name.name#gmail.com","fff4b8d75ecdfad43ed8c89444939cfb","name.name","name.name#gmail.com","","1141956489","","2","name.name"
