MySQL separate values by user - mysql

Question

i have recovered a database from a cmsms website and with Mysql i want to extract all the login information of the front-end users . i work with Heidisql
My problem user_proprerties DB is in this form:
Id UserID Type Data
1 2 email 1#2be.net
2 2 company lorme ipsum
3 2 fname testname
4 5 email& 2#2be.com
5 5 company empty
6 5 fname dolor sir amed
i want the data to be in this form:
Userid email company fname
2 1#2be.be lorem testname
5 2#2be.be emptydolor sir amed
this is the current mysql query that i have
select
cms_module_feusers_users.id,
cms_module_feusers_users.username,
cms_module_feusers_users.createdate,
cms_module_feusers_users.expires,
cms_module_feusers_properties.`data` email
from
cms_module_feusers_users
inner join cms_module_feusers_properties on cms_module_feusers_properties.userid = cms_module_feusers_users.id
where
cms_module_feusers_properties.title = 'email'
But now i'm stuck when i want the company name and fname.

Answer 1

(Fractionally) slower, but cleaner...
SELECT p.userid
, MAX(CASE WHEN type = 'email' THEN data END) email
, MAX(CASE WHEN type = 'company' THEN data END) company
, MAX(CASE WHEN type = 'fname' THEN data END) fname
FROM cms_module_feusers_properties p
GROUP
BY p.userid;

Answer 2

Add a join for each field you need
SELECT
user.id,
user.whatever,
<other stuff from cms_module_feusers_users...>
user_email.`data` as email,
user_company.`data` as company,
<other stuff from cms_module_feusers_properties...>
FROM cms_module_feusers_users user
LEFT JOIN cms_module_feusers_properties user_email ON user_email.userid = user.id AND user_email.title = 'email'
LEFT JOIN cms_module_feusers_properties user_company ON user_company.userid = user.id AND user_company.title = 'company'
<other joins from cms_module_feusers_properties...>
WHERE <conditions related to users...>
You need to use LEFT JOIN because some properties might be missing in cms_module_feusers_properties.
Also this assumes that each property appears at most once for each user.

Try this:
SELECT
cms_module_feusers_users.id,
cms_module_feusers_users.username,
cms_module_feusers_users.createdate,
cms_module_feusers_users.expires,
prop_data.data AS email,
prop_data_company.data AS company,
prop_data_fname.data AS fname
FROM
cms_module_feusers_users
INNER JOIN
(SELECT
*
FROM
cms_module_feusers_properties
WHERE
type = 'email') prop_data ON prop_data.userid = cms_module_feusers_users.id
INNER JOIN
(SELECT
*
FROM
cms_module_feusers_properties
WHERE
type = 'company') prop_data_company ON prop_data_company.userid = cms_module_feusers_users.id
INNER JOIN
(SELECT
*
FROM
cms_module_feusers_properties
WHERE
type = 'fname') prop_data_fname ON prop_data_fname.userid = cms_module_feusers_users.id
