I made a query that list all the players on all the teams for each of the clubs in my site.
A "club" has "teams" and each team has "players", I solve the listing using this query:
SELECT
Club.*,
Teams.*,
Players.*
FROM
(Club LEFT JOIN Teams ON Club.idClub = Teams.idClub)
LEFT JOIN
Teams ON Teams.idEquipos_Categorias = Players.idEquipos_Categorias
WHERE
Teams.idTemporadas = 2017
It works great, now I want to list just the players than "has played" from other table "hasPlay" I made this changes, but It returns empty:
SELECT
Club.*,
Teams.*,
Players.*,
HasPlay.*
FROM
((Club LEFT JOIN Teams ON Club.idClub = Teams.idClub)
LEFT JOIN
Teams ON Teams.idEquipos_Categorias = Players.idEquipos_Categorias) LEFT JOIN HasPLay ON Players.idPlayer = HasPlay.idPlayer
WHERE
Teams.idTemporadas = 2017
I think I mess it up in the last join...
Any advice is well recieved
I doubt your original query works
as it contains various errors and anomalies
anyway you should avoid useless ()
and especially use JOIN on the Equipos_Categorias table eg:
SELECT
Club.*,
Teams.*,
Players.*,
HasPlay.*
FROM Club LEFT JOIN Teams ON Club.idClub = Teams.idClub
LEFT JOIN Teams ON Teams.idEquipos_Categorias = Players.idEquipos_Categorias
LEFT JOIN HasPLay ON Players.idPlayer = HasPlay.idPlayer
INNER JOIN Equipos_Categorias ON Teams.idEquipos_Categorias = Equipos_Categorias.idEquipos_Categorias
and Equipos_Categorias.idTemporadas = 2017
ORDER BY Club.nombre, Equipos_Categorias.idEquipos_Categorias ASC,
Jugadores_Equipos.categoriaJugador ASC, Jugadores_Equipos.nombre ASC
and as verified by OP uisng team table
SELECT
Club.*,
Teams.*,
Players.*,
HasPlay.*
FROM Club LEFT JOIN Teams ON Club.idClub = Teams.idClub
INNER JOIN Teams ON Teams.idEquipos_Categorias = Players.idEquipos_Categorias and team.idTemporadas = 2017
LEFT JOIN HasPLay ON Players.idPlayer = HasPlay.idPlayer
ORDER BY Club.nombre, Equipos_Categorias.idEquipos_Categorias ASC,
Jugadores_Equipos.categoriaJugador ASC, Jugadores_Equipos.nombre ASC

I'm trying to join several tables in my database.
I need to get account information from the 'accounts' table with the latest meter history on it.
And if an account has no meter history, I want it to show 'meter' related fields as NULL.
Here's my query so far:
SELECT
accounts.id,
accounts.account_order,
acc.id AS accounts_class_id,
acc.zone,
acc.book,
acc.service_class,
acc.size,
acc.account_no AS series_no,
accounts.status,
application_address.address_line,
concessionaires.firstname,
concessionaires.middlename,
concessionaires.lastname,
mb.brand_name,
m.meter_no,
ms.meter_status
FROM
accounts
INNER JOIN
applications
ON accounts.application_id = applications.id
LEFT JOIN
application_address
ON applications.application_no = application_address.application_no
LEFT JOIN
concessionaires
ON applications.concessionaire_no = concessionaires.concessionaire_no
INNER JOIN
accounts_classifications acc
ON accounts.id = acc.account
INNER JOIN meter_history mh
ON mh.id = (SELECT id FROM meter_history mh2
WHERE mh2.account_id = accounts.id
ORDER BY mh2.status_date DESC
LIMIT 1)
LEFT JOIN
meter_status ms
ON mh.meter_status = ms.id
INNER JOIN
meter m
ON mh.meter = m.id
LEFT JOIN
meter_brand mb
ON m.meter_brand = mb.id
WHERE
acc.book = 1 AND acc.zone = 20 AND applications.status = '6' AND acc.status = '1'
This would return only accounts with meter history on it.
Where should I put my IF condition so I get accounts with no history as well, or if that is even possible with my query. Thank you!
So I'm having a slight problem with having to save price on a product in two different tables due to a few reasons. Is it possible to merge two columns into one? I know UNION exists but does it work with LEFT JOIN's?
Any pointers is much appreciated.
Best Regards
SELECT
si.id AS shop_item_id,
si.item_price,
s.logo_file_name,
p.cat_id AS category_id,
api.item_price AS api_price,
MAX(c.campaign_desc) AS campaignDesc,
MAX(c.campaign_type_id) AS campaignType,
MAX(c.shop_id) AS campaign_shop_id,
MAX(ct.image_name) AS campaignLogo
FROM
shop_item si
LEFT JOIN
shop s ON
s.id = si.shop_id
LEFT JOIN
product p ON
si.product_id = p.id
LEFT JOIN
campaign_category cc ON
cc.category_id = p.cat_id
LEFT JOIN
campaign c ON
c.id = cc.campaign_id AND
c.shop_id = si.shop_id AND
c.show_in_pricetable = 1 AND
NOW() BETWEEN c.date_from and c.date_to
LEFT JOIN
campaign_type ct ON
c.campaign_type_id = ct.id
LEFT JOIN
shop_api_item api ON
si.rel_feed_api = api.unique_id AND si.shop_id = api.shop_id
WHERE
si.`product_id` = 586 AND
s.`active_shop` = 1
GROUP BY
s.name,
si.id ,
si.item_price
ORDER BY
si.`item_price`,
si.`shop_id`,
c.`campaign_desc` DESC
It looks like you would benefit from the COALESCE() function.
SELECT
si.id AS shop_item_id,
COALESCE(si.item_price, api.item_price) AS coalesced_price,
...
COALESCE() takes multiple arguments, and returns the first argument that is not NULL.
I have a problem in a query.
i need to make a page where user can see all reservations he made with movie name, cinema name, seats code that he reserved
i reached this level
SELECT member.member_username, show_datetime, movie_name
FROM `member`
JOIN `reservation` ON `reservation`.`member_id` = `member`.`member_id`
JOIN `show` ON `show`.`show_id`= `reservation`.`show_id`
JOIN `movie` ON `movie`.`movie_id` = `show`.`movie_id`
WHERE `reservation`.`member_id`=1
i need to make a connection and get also the cinema_name from cinema table and seats_code from seat table and theater name
in fact, i need a query to give me all almost all data in my whole database
here is the schema for the DB
http://imageshack.us/photo/my-images/824/58054944.jpg/
JOIN these two tables too:
SELECT
m.member_username,
sh.show_datetime,
v.movie_name,
c.cinema_name,
t.theater_name
FROM member AS m
INNER JOIN reservation AS r ON r.member_id = m.member_id
INNEr JOIN show AS sh ON sh.show_id = r.show_id
INNER JOIN movie AS v ON v.movie_id = s.movie_id
INNER JOIN theater AS t ON t.theater_id = sh.theater_id
INNER JOIN cinema AS c ON c.theater_id = sh.theater_id
WHERE r.member_id = 1
Keep joining your tables
SELECT member.member_username, show_datetime, movie_name, c.cinema_name, t.theater_name
FROM `member`
JOIN `reservation` ON `reservation`.`member_id` = `member`.`member_id`
JOIN `show` ON `show`.`show_id`= `reservation`.`show_id`

JOIN `cinema` ON `theater`.`cinema_id` = `cinema`.`cinema_id`
JOIN `seat` ON `show`.`theater_id` = `seat`.`theater_id`
WHERE `reservation`.`member_id`=1
I'm creating a database that is going to be used for a sporting competition. To view the results of a game, I need to join six tables together:
Season s
Round r
Rounddetails rd
Match m
Matchdetails md
Game g
I want the select statement to return something like this:
g.gameid, g.pointsfor, g.pointsagainst, md.matchdetailsid, m.matchid, rd.rounddetailsid, r.roundid, s.seasonid
Could anyone help me write a MySQL statement that will return that?
Please click the link to view the tables
EDIT: so far I have tried this query:
select
`s`.`seasonID` AS `seasonID`,
`r`.`roundID` AS `roundid`,
`rd`.`roundDetailsID` AS `roundDetailsID`,
`m`.`matchid` AS `matchid`,
`md`.`matchDetailsID` AS `matchDetailsID`,
`g`.`gameid` AS `gameid`,
`g`.`pointsfor` AS `pointsfor`,
`g`.`pointsagainst` AS `pointsagainst`
from (((((`season` `s` left join `round` `r` on((`s`.`SeasonID` = `r`.`SeasonID`)))
left join `rounddetails` `rd` on((`r`.`RoundID` = `rd`.`RoundID`)))
left join `match` `m` on((`rd`.`matchid` = `m`.`matchid`)))
left join `matchdetails` `md` on((`m`.`matchid` = `md`.`matchid`)))
left join `game` `g` on((`md`.`matchdetailsid` = `g`.`matchdetailsid`)))
SELECT DISTINCT g.gameid, g.pointsfor, g.pointsagainst, md.matchdetailsid, m.matchid, rd.rounddetailsid, r.roundid, s.seasonid
FROM Match AS m
INNER JOIN MatchDetails as md
ON Match.MatchId = MatchDetails.MatchId
INNER JOIN Game as g
ON MatchDetails.MatchDetailSid = MatchDetailSid
INNER JOIN RoundDetails as rd
ON Match.MatchId = RoundDetails.MatchId
INNER JOIN Round as r
ON Round.RoundId = RoundDetails.RoundId
INNER JOIN Season as s
ON Round.SeasonId = Season.SeasonId
WHERE MatchId = 1
Somehow am not successful with creating the query that I want.
DB is to do with locations, there are the following tables which are relevant
t_location - list of locations incl. field t_location_zipcode, and t_location_id_location
t_zipcodecity - join table just t_zipcodecity_zipcode t_zipcodecity_id_city
t_city - city list with t_city_id_city
t_citystate - join table, t_citystate_id_city, t_citystate_id_state
t_state - list of states with t_state_id_state
Initially I tried to get a list of states with locations using this query:
SELECT DISTINCT `t_state_id_state`
, `t_state_name_full`
FROM (`t_state`)
LEFT JOIN `t_citystate` ON `t_state_id_state` = `t_citystate_id_state`
LEFT JOIN `t_city` ON `t_citystate_id_state` = `t_city_id_city`
LEFT JOIN `t_zipcodecity` ON `t_city_id_city` = `t_zipcodecity_id_city`
LEFT JOIN `t_location` ON `t_zipcodecity_zipcode` = `t_location_zipcode`
ORDER BY `t_state_name_full` asc
which works fine.
Now what I also need / want which I am failing dismally at is to get the number of locations in each state. I don't know if it can be done in this one query or if i need another, either way I need help!
you can use a count and a group by. Something like this:
SELECT DISTINCT `t_state_id_state`
, `t_state_name_full`
, COUNT(*)
FROM (`t_state`)
LEFT JOIN `t_citystate` ON `t_state_id_state` = `t_citystate_id_state`
LEFT JOIN `t_city` ON `t_citystate_id_state` = `t_city_id_city`
LEFT JOIN `t_zipcodecity` ON `t_city_id_city` = `t_zipcodecity_id_city`
LEFT JOIN `t_location` ON `t_zipcodecity_zipcode` = `t_location_zipcode`
GROUP BY `t_state_id_state` , `t_state_name_full`
ORDER BY `t_state_name_full` asc
SELECT t_state_id_state
, t_state_name_full
, COUNT(DISTINCT t_location_id_location) AS locations_number
FROM
t_state
LEFT JOIN
t_citystate ON t_state_id_state = t_citystate_id_state
LEFT JOIN
t_city ON t_citystate_id_state = t_city_id_city
LEFT JOIN
t_zipcodecity ON t_city_id_city = t_zipcodecity_id_city
LEFT JOIN
t_location ON t_zipcodecity_zipcode = t_location_zipcode
GROUP BY t_state_id_state
ORDER BY t_state_name_full ASC
Ok thats looking good, my bad with the left joins, i was initially trying to get ALL the states which is why i used them. But i change that to use inner joins
SELECT t_state_id_state,
t_state_name_full,
COUNT(DISTINCT t_location_id_location) AS locations_number
FROM t_state
INNER JOIN t_citystate ON t_citystate_id_state = t_state_id_state
INNER JOIN t_city ON t_city_id_city = t_citystate_id_city
INNER JOIN t_zipcodecity ON t_zipcodecity_id_city = t_city_id_city
INNER JOIN t_location ON t_location_zipcode = t_zipcodecity_zipcode
GROUP BY t_state_id_state
ORDER BY t_state_name_full ASC
then i actually end up with a result that looks good !
