I'm new on laravel.
How do I run this query on laravel?
SELECT a.id, active, name, email, IFNULL(b.Total, 0) AS leads
FROM users AS a
LEFT JOIN (
SELECT user_id, count(*) as Total
FROM lead_user
GROUP BY user_id
) AS b
ON a.id= b.user_id
WHERE is_deleted = 0
Thanks!
well, since you have the query already written...
DB::statement('
SELECT a.id, active, name, email, IFNULL(b.Total, 0) AS leads
FROM users AS a
LEFT JOIN (
SELECT user_id, count(*) as Total
FROM lead_user
GROUP BY user_id
) AS b
ON a.id= b.user_id
WHERE is_deleted = 0
');
Here are the docs

I'm trying to create a leaderboard but i'm not sure how to do the mysql query.
I would like to count all the levels from a player in the skills table and get the total Level and count all the experience from a player in the experience table and get the Total Exp along with displaying the persons name from the users column.
There is 3 tables factions_mcmmo_users, factions_mcmmo_experience, factions_mcmmo_skills.
This is what i have so far but it doesn't work:
$sql = ("SELECT a.id,
(SELECT COUNT(*) FROM factions_mcmmo_experience WHERE user_id = a.id) as TotalXP,
(SELECT COUNT(*) FROM factions_mcmmo_skills WHERE user_id = a.id) as TotalLevel
FROM (SELECT DISTINCT id FROM factions_mcmmo_users) a LIMIT 10;");
Any help would be very appreciated
EDIT: I have it working now but i'm unsure if its the most efficient way to do things so if anyone could help me out if theres a better way, it would mean a lot.
I would also like to know if it's possible to display the total exp and level with commas if the number is in the thousands for example: total level 5,882 and total xp 582,882
EDIT 2:
I have figured out how to format the numbers but still don't know if my code is efficient
$sql = ("SELECT id, user,
(SELECT FORMAT(Sum(taming)+Sum(mining)+Sum(woodcutting)+Sum(repair)+Sum(unarmed)+Sum(herbalism)+Sum(excavation)+Sum(archery)+Sum(swords)+Sum(axes)+Sum(acrobatics)+Sum(fishing)+Sum(alchemy),0) FROM factions_mcmmo_skills b WHERE b.user_id = a.id) as TotalLevel,
(SELECT FORMAT(Sum(taming)+Sum(mining)+Sum(woodcutting)+Sum(repair)+Sum(unarmed)+Sum(herbalism)+Sum(excavation)+Sum(archery)+Sum(swords)+Sum(axes)+Sum(acrobatics)+Sum(fishing)+Sum(alchemy),0) FROM factions_mcmmo_experience c WHERE c.user_id = a.id) as TotalXP
FROM (SELECT id, user FROM factions_mcmmo_users) a group by id ORDER BY TotalLevel DESC, TotalXP DESC LIMIT 10;");
EDIT 3
Updated code from scaisEdge but was displaying everyones level as 1 and XP as 1, so i changed count(*) changed to sum, added an order By TotalLevel in Descending order and that seems to have worked but i can't get it to display the persons name (user column) in the user table? not sure if i was supposed to change to sum because it didn't work the other way.
$sql = ("SELECT a.id, b.TotalXP, c.TotalLevel
FROM (SELECT DISTINCT id FROM factions_mcmmo_users) a
INNER JOIN (
SELECT user_id, Sum(taming)+Sum(mining)+Sum(woodcutting)+Sum(repair)+Sum(unarmed)+Sum(herbalism)+Sum(excavation)+Sum(archery)+Sum(swords)+Sum(axes)+Sum(acrobatics)+Sum(fishing)+Sum(alchemy) as TotalXP
FROM factions_mcmmo_experience
GROUP By user_id
) b on b.user_id = a.id
INNER JOIN (
SELECT user_id, Sum(taming)+Sum(mining)+Sum(woodcutting)+Sum(repair)+Sum(unarmed)+Sum(herbalism)+Sum(excavation)+Sum(archery)+Sum(swords)+Sum(axes)+Sum(acrobatics)+Sum(fishing)+Sum(alchemy) as TotalLevel
FROM factions_mcmmo_skills
GROUP by user_id
) c on c.user_id = a.id
ORDER BY TotalLevel DESC
LIMIT 10;");
EDIT 4
Everything working but when i try to format the totals using "FORMAT(Sum(Columns), 0) on the inner joins, the EXP Total appears to work but the main Total Level is not displaying results that are over 1,000 and it breaks the leaderboard positioning, it should be sorting them on total level but it appears to be random, when u remove the format,0 it goes back to working
I would like it to display commas if the number number is the thousands for example: Total Level: 5,532 and Total EXP 5882,882
See live demo: http://mcbuffalo.com/playground/leaderboards/server/factions-mcmmo.php
Updated Code trying to use Format:
$sql = ("SELECT a.id, a.user, b.TotalXP, c.TotalLevel
FROM (SELECT id, user FROM factions_mcmmo_users) a
INNER JOIN (
SELECT user_id, FORMAT(Sum(taming)+Sum(mining)+Sum(woodcutting)+Sum(repair)+Sum(unarmed)+Sum(herbalism)+Sum(excavation)+Sum(archery)+Sum(swords)+Sum(axes)+Sum(acrobatics)+Sum(fishing)+Sum(alchemy), 0) as TotalXP
FROM factions_mcmmo_experience
GROUP By user_id
) b on b.user_id = a.id
INNER JOIN (
SELECT user_id, FORMAT(Sum(taming)+Sum(mining)+Sum(woodcutting)+Sum(repair)+Sum(unarmed)+Sum(herbalism)+Sum(excavation)+Sum(archery)+Sum(swords)+Sum(axes)+Sum(acrobatics)+Sum(fishing)+Sum(alchemy), 0) as TotalLevel
FROM factions_mcmmo_skills
GROUP by user_id
) c on c.user_id = a.id
ORDER BY TotalLevel DESC;");
EDIT 5
Changed number with PHP, everything works

you could use an couple of inner join
$sql = ("SELECT a.id, a.name, b.TotalXP, c.TotalLevel
FROM (SELECT DISTINCT id, name FROM factions_mcmmo_users) a
INNER JOIN (
SELECT user_id, COUNT(*) as TotalXP
FROM factions_mcmmo_experience
GROUP By user_id
) b on b.user_id = a.id
INNER JOIN (
SELECT user_id, COUNT(*) as TotalLevel
FROM factions_mcmmo_skills
GROUP by user_id
) c on c.user_id = a.id
LIMIT 10
I am trying to do a MYSQL query where I get the most recent purchase for a user and then see if falls within certain criteria. Here is the query I put together:
select
users_purch.purch_date as purchase_date,
users_purch.total_amount as purchase_amount,
users.*
from
users
left join
(
select
max(date) as purch_date,
user_id,
total_amount
from
users_purchases
group by
user_id
) as users_purch
on users_purch.user_id = users.id
where
users_purch.purch_date < '2016-11-01'
and users_purch.total_cost < 112.49
order by
users_purch.purch_date desc
It seems that the query works but fails in certain aspects. For example, if a user has more than one purchase entry it is getting the max date but the amount as total_cost that the query retrieves is not from the same row as the max date. How can I rewrite this query to give me the most recent purchase record in its entirety?
Thanks!
You have to join once more to user_purchases table in order to get the information about the date:
select
users_purch.purch_date as purchase_date,
users_purch.total_amount as purchase_amount,
users.*
from
users
left join
(
select
max(date) as purch_date,
user_id
from
users_purchases
group by
user_id
) as users_purch
on users_purch.user_id = users.id
left join
(
select
user_id,
date,
total_amount
from
users_purchases
) as users_purch2 on users_purch.user_id = users_purch2.user_id and
users_purch2.date = users_purch.purch_date
where
users_purch.purch_date < '2016-11-01'
and users_purch.total_cost < 112.49
order by
users_purch.purch_date desc
due the group by you have in this select
if you need the amount of the max(date) rewrite extecting the proper amount
select
users_purch.purch_date as purchase_date,
users_purch.total_amount as purchase_amount,
users.*
from
users
left join
(
select t1.purch_date, t1.user_id, t2.total_amount from (
select
max(date) as purch_date,
user_id
from users_purchases
group by user_id ) t1
inner join (
date,
user_id,
total_amount
from users_purchases
) t2 on t1.user_id= t2.user_id, t1.purch_date = t2.date
) as users_purch
on users_purch.user_id = users.id
where
users_purch.purch_date < '2016-11-01'
and users_purch.total_cost < 112.49
order by
users_purch.purch_date desc
You can try this one, mate:
SELECT
up.date AS 'purchase_date',
up.total_amount AS 'purchase_amount',
u.*
FROM
users u
INNER JOIN users_purchases up ON up.user_id = u.user_id
INNER JOIN (
# get max date per user_id
SELECT user_id, max(date) AS 'purch_date'
FROM users_purchases
GROUP BY user_id
) max_up ON
max_up.user_id
# join that date to get the correct total_amount
AND max_up.`purch_date` = up.`date`
WHERE
up.`date` < '2016-11-01'
AND up.total_amount < 112.49
GROUP BY u.user_id
ORDER BY up.`date` DESC;
Note
Max Date per user_id
Value of total_amount per Max Date
Grouped per user_id
Ordered descending using users_purchases.date
I have a query that LEFT JOINS another table to group rows. I am trying to only select records from the first table "googleimage" where the user_id is a certain number. (user_id is a column in "googleimage" table.
SELECT g.*
FROM googleimage g
LEFT JOIN (SELECT image_id, COUNT(*) AS cnt
FROM googleimagefound WHERE status = 0
GROUP BY image_id) gf ON gf.image_id = g.id
ORDER BY COALESCE(cnt, 0) DESC");
I have tried adding a new ON statement beiside the
gf ON gf.image_id = g.id
I have also tried changing
SELECT g.*
FROM googleimage g
to
SELECT g.*
FROM googleimage WHERE user_id = 1 g
but none of them seem to work, any help will be appriciated
Try changing you query a bit like below
SELECT g.*
FROM googleimage g
LEFT JOIN (SELECT image_id, COUNT(*) AS cnt
FROM googleimagefound WHERE status = 0
GROUP BY image_id) gf ON gf.image_id = g.id
WHERE g.user_id = 1 <-- add this condition
ORDER BY COALESCE(gf.cnt, 0) DESC;
The following statement gets row counts for user_ids from various tables/conditions where the users are within specific computers of a specific account. It works as expected. An example output would be something like this :
Array
(
[0] => Array
(
[computer_name] => COMPUTER_1
[username] => Steve
[t1count] => 13
[t2count] =>
[t3count] => 23
[t4count] => 64
)
... and so on for each
the statement :
$stmt = $db->prepare("
SELECT c.computer_name, users.username, t1count, t2count, t3count, t4count
FROM
( SELECT account_id, computer_id, computer_name
FROM computers
WHERE account_id = ".$_SESSION['user']['account_id']."
ORDER BY computer_id ASC LIMIT 0, ".$_SESSION['user']['licenses']."
) as c
LEFT JOIN users
on users.computer_id = c.computer_id
LEFT JOIN
(SELECT user_id, COUNT(user_id) as t1count
FROM t1
WHERE t1.title LIKE 'started'
GROUP BY user_id) as t_t1
on t_t1.user_id = users.user_id
LEFT JOIN
(SELECT user_id, COUNT(user_id) as t2count
FROM t2
GROUP BY user_id) as t_t2
on t_t2.user_id = users.user_id
LEFT JOIN
(SELECT user_id, COUNT(user_id) as t3count
FROM t1
WHERE t1.title LIKE 'blocked'
GROUP BY user_id) as t_t3
on t_t3.user_id = users.user_id
LEFT JOIN
(SELECT user_id, COUNT(user_id) as t4count
FROM t1
WHERE t1.title LIKE 'closed'
GROUP BY user_id) as t_t4
on t_t4.user_id = users.user_id
... and so on for each
WHERE c.account_id = ?
");
I want to also return a totalsum = t1count + t2count + t3count + t4count in this statement as well, but can't seem to get anything working. In this situation I cannot do outside processing (adding the values that are returned)... it needs to be in the statement. I am also open to any suggestions in what I already have if there are better options.
What are you trying to do with these values? SUM(t1count,t2count,t3count,t4count) AS totalsum should work to get a count of counts.
Your query is a bit hard to read. You have implicit and explicit JOINs. You are grouping numerous times and pulling columns when you can generally do this all in one shot. If you share an SQLFiddle, I will be able to clean this up, but in short:
SELECT
c.computer_name,
users.username,
count(t_t1.user_id) AS t1count,
count(t_t2.user_id) AS t2count,
count(t_t3.user_id) AS t3count,
count(t_t4.user_id) AS t4count,
(count(t_t1.user_id)+count(t_t2.user_id)+count(t_t3.user_id)+count(t_t4.user_id)) AS totalsum FROM users
LEFT JOIN computers AS c ON users.computer_id=c.computer_id AND c.account_id=?
LEFT JOIN t1 AS t_t1 ON t_t1.user_id = users.user_id AND t_t1.title LIKE "started"
LEFT JOIN t2 AS t_t2 ON t_t2.user_id = users.user_id
LEFT JOIN t1 AS t_t3 ON t_t3.user_id = users.user_id AND t_t3.title LIKE 'blocked'
LEFT JOIN t1 AS t_t4 ON t_t4.user_id = users.user_id AND t_t4.title LIKE 'closed'
WHERE c.account_id = ?
AND t_t1.title LIKE started
GROUP BY users.user_id;
This may need tweaking, as I stated, but it is a lot cleaner and easier to read and should accomplish something very similar.
Alternately, if you can't get the query to run the way you want it to when you change it to entirely explicit joins, rather than using SUM, try adding the values together like I did in the example above. It should prevent them from aggregating in the same way.
EDIT
After viewing your SQLFiddle, I have doctored up a solution which does away with nested queries. The positive is that it is cleaner. The negative is that it requires you to specify the users using an IN clause.
SELECT computers.account_id,computers.computer_id,computers.computer_name,users.user_id,users.username,count(distinct t_count1.log_id) AS count1,count(distinct t_count2.log_id) AS count2,count(distinct t_count3.log_id) AS count3, count(distinct t_count4.event_id) AS count4,
(count(distinct t_count1.log_id) + count(distinct t_count2.log_id) + count(distinct t_count3.log_id) + count(distinct t_count4.event_id)) AS totalcount
FROM users
INNER JOIN computers ON computers.computer_id=users.computer_id
LEFT JOIN logs AS t_count1 ON t_count1.type LIKE 'type1' AND t_count1.user_id=users.user_id
LEFT JOIN logs AS t_count2 ON t_count2.type LIKE 'type2' AND t_count2.user_id=users.user_id
LEFT JOIN logs AS t_count3 ON t_count3.type LIKE 'type3' AND t_count3.user_id=users.user_id
LEFT JOIN events AS t_count4 ON t_count4.user_id = users.user_id
WHERE computers.account_id=1 AND computers.computer_id in (1,2)
GROUP BY users.user_id
ORDER BY users.user_id ASC,computers.computer_id ASC;
If you choose to keep your current query structure for any reason, adapting it like so should make it work for you:
select *,ifnull(count1,0)+ifnull(count2,0)+ifnull(count3,0)+ifnull(count4,0) AS totalcount from
( select account_id, computer_id, computer_name
from computers
order by computer_id asc limit 0, 2
) as c
left join users
on users.computer_id = c.computer_id
left join
(select user_id, count(user_id) as count1
from logs
where logs.type like 'type1'
group by user_id) as t_count1
on t_count1.user_id = users.user_id
left join
(select user_id, ifnull(count(user_id),0) as count2
from logs
where logs.type like 'type2'
group by user_id) as t_count2
on t_count2.user_id = users.user_id
left join
(select user_id, count(user_id) as count3
from logs
where logs.type like 'type3'
group by user_id) as t_count3
on t_count3.user_id = users.user_id
left join
(select user_id, count(user_id) as count4
from events
group by user_id) as t_count4
on t_count4.user_id = users.user_id
where c.account_id = 1;
My advice would be to follow along each query to understand what you are asking SQL to do. To actually add all values together, you should be counting the number of records that are returned. Counting values of your primary keys helps you to count records. Also, using your other example, ifnull in the second example make sure that null values are not going to interfere with adding. "If a value is null make it 0 instead."
$query = $this->db->query("SELECT t1.numberofbets, t1.profit, t2.seven_profit, t3.28profit, user.user_id, username, password, email, balance, user.date_added, activation_code, activated FROM user LEFT JOIN (SELECT user_id, SUM(amount_won) AS profit, count(tip_id) AS numberofbets FROM tip GROUP BY user_id) as t1 ON user.user_id = t1.user_id LEFT JOIN (SELECT user_id, SUM(amount_won) AS seven_profit FROM tip WHERE date_settled > '$seven_daystime' GROUP BY user_id) as t2 ON user.user_id = t2.user_id LEFT JOIN (SELECT user_id, SUM(amount_won) AS 28profit FROM tip WHERE date_settled > '$twoeight_daystime' GROUP BY user_id) as t3 ON user.user_id = t3.user_id where activated = 1 GROUP BY user.user_id ORDER BY user.date_added DESC");
return $query->result_array();
The query works fine running it in phpMyAdmin and returns complete results (in image attached). However, printing the array in CodeIgniter, it has no value for one field ,seven_profit, where it is there in the SQL query ran in phpMyAdmin, just the discrepancy in this one field, from sql to php array... I just can’t see why, when printing the array, that one field, which should have value of 26, contains nothing? Any ideas? I changed the field name from starting with a number in attempt to fix it, but no difference.
I know this is complex and looks horrible, any help or just people coming across something similar would be great to know about, thanks.
Sam
edit: the query a bit more formatted:
$query = $this->db->query("
SELECT
t1.numberofbets, t1.profit, t2.seven_profit, t3.28profit,
user.user_id, username, password, email,
balance, user.date_added, activation_code, activated
FROM
user
LEFT JOIN
(
SELECT
user_id,
SUM(amount_won) AS profit,
count(tip_id) AS numberofbets
FROM
tip
GROUP BY
user_id
) as t1
ON
user.user_id = t1.user_id
LEFT JOIN
(
SELECT
user_id,
SUM(amount_won) AS seven_profit
FROM
tip
WHERE
date_settled > '$seven_daystime'
GROUP BY
user_id
) as t2
ON
user.user_id = t2.user_id
LEFT JOIN
(
SELECT
user_id,
SUM(amount_won) AS 28profit
FROM
tip
WHERE
date_settled > '$twoeight_daystime'
GROUP BY
user_id
) as t3
ON
user.user_id = t3.user_id
WHERE
activated = 1
GROUP BY
user.user_id
ORDER BY
user.date_added DESC
");
Ok the problem was the SQL query includes PHP variables, these variables must just be treated as 0 or something without giving errors, so it displays a value in the seven_profit column.
When the query is ran in CodeIgniter it uses the correct value for $seven_daystime variable, and therefore the result is different when the data is put into the array.
