mysql query from three tables - mysql

I'm using this query
SELECT
orders_list.nr_comanda_orders AS Comanda,
SUM(orders_list.cantitate) AS Total,
SUM(orders_list.qty_to_add) AS InStoc,
COUNT(entries_list.id) AS Picked
FROM orders_list
LEFT JOIN entries_list ON (entries_list.file_id = orders_list.id AND entries_list.orders_list_id = orders_list.nr_comanda_orders)
GROUP BY orders_list.nr_comanda_orders
ORDER BY orders_list.nr_comanda_orders DESC
which has this result
Comanda | Total | InStoc | Picked
-----------|----------------|--------
AAY280838 | 64 | 6 | 0
AAY280837 | 50 | 8 | 0
AAY280836 | 89 | 8 | 0
and a second query
SELECT
entries_list.orders_list_id AS Comanda,
SUM(orders_list.cantitate) AS Total,
SUM(orders_list.qty_to_add) AS InStoc,
COUNT(entries_list.id) AS Picked
FROM entries_list
LEFT JOIN orders_list ON (entries_list.file_id = orders_list.id AND entries_list.orders_list_id = orders_list.nr_comanda_orders)
LEFT JOIN orders_uploaded ON orders_list.file_id = orders_uploaded.id
GROUP BY
entries_list.orders_list_id
ORDER BY
entries_list.orders_list_id DESC,
orders_uploaded.id_routing DESC,
orders_uploaded.upload_date DESC,
orders_uploaded.progress ASC
which has this result:
Comanda | Total | InStoc | Picked
-----------|------------------|--------
AAY280838 | NULL | NULL | 55
AAY280837 | NULL | NULL | 39
AAY280836 | NULL | NULL | 76
Could you please help me with the query so I can get this result?
Comanda | Total | InStoc | Picked
-----------|----------------|--------
AAY280838 | 64 | 6 | 55
AAY280837 | 50 | 8 | 39
AAY280836 | 89 | 8 | 76
Thanks in advance.

How to count in mysql

I have this query in mySQL where I would like to sum the line product of each doctor but I dont know how to do it.
use avant_medical;
select
sales.doctor_id as DoctorID,
line_products.id as LineProductID,
line_products.name as LineProductName
from `doctors`
inner join `sales` on `doctors`.`id` = `sales`.`doctor_id`
inner join `inventories` on `sales`.`id` = `inventories`.`sale_id`
inner join `products` on `inventories`.`product_id` = `products`.`id`
inner join `line_products` on `products`.`lineProduct_id` = `line_products`.`id`
order by `doctors`.`id` asc;
lPID= lineProductID
|DrID|lPID |
| -- | ----|
| 1 | 7 |
| 1 | 6 |
| 1 | 6 |
| 1 | 7 |
| 1 | 7 |
| 1 | 7 |
| 1 | 6 |
This is how I want:
Doctor 1
lineID | quantity
7 | 4
6 | 3
I try this query only in mySQL
The keyword you are looking for is count, not sum. Summing would add up every lineProductID as if they where regular mathematical values, while counting will add up how many times a given lineProductID is found.
select
sales.doctor_id as DoctorID,
line_products.id as LineProductID,
line_products.name as LineProductName,
-- We count the number of occurrences of each line_product.id
COUNT(line_products.id) as LineProductQty
from `doctors`
inner join `sales` on `doctors`.`id` = `sales`.`doctor_id`
inner join `inventories` on `sales`.`id` = `inventories`.`sale_id`
inner join `products` on `inventories`.`product_id` = `products`.`id`
inner join `line_products` on `products`.`lineProduct_id` = `line_products`.`id`
-- Never forget to properly GROUP your aggregate functions, such as COUNT() or SUM()!
GROUP BY sales.doctor_id, line_products.id, line_products.name
order by `doctors`.`id` asc;
Since you didn't provided full schema to test this, I made a small, very artificial demo, but should be representative of how the query above works.

Ordering issue when using SQL variable

I run this query:
SELECT stockcarddetail.id, stockcarddetail.date, stockcarddetail.quantity, stockcarddetail.pricePerItem
FROM Stockcard
LEFT JOIN staff
ON staff.branchId = stockcard.branchId
LEFT JOIN stockcarddetail
ON stockcarddetail.stockcardId = stockcard.id
WHERE staff.username = 'jemmy.h'
AND stockcarddetail.quantity > 0
AND stockcard.productId = '98924a5f-6afb-11e7-8dd4-2c56dcbcb038'
ORDER BY date ASC
and get the result below:
id | date | quantity| pricePerItem
50 | 2017-10-15 | 10.00 | 10000.00
1 | 2017-10-18 | 20.00 | 10000.00
Then, I need to calculate the cumulative of quantity based on the order above, so I run this query:
SELECT a.*, #tot:=#tot + a.quantity FROM
(SELECT #tot:= 0)b
JOIN
(SELECT stockcarddetail.id, stockcarddetail.date, stockcarddetail.quantity, stockcarddetail.pricePerItem
FROM Stockcard
LEFT JOIN staff
ON staff.branchId = stockcard.branchId
LEFT JOIN stockcarddetail
ON stockcarddetail.stockcardId = stockcard.id
WHERE staff.username = 'jemmy.h'
AND stockcarddetail.quantity > 0
AND stockcard.productId = '98924a5f-6afb-11e7-8dd4-2c56dcbcb038'
ORDER BY date ASC) a
Then I got this result:
id | date | quantity| pricePerItem | #tot
1 | 2017-10-18 | 20.00 | 10000.00 | 20
50 | 2017-10-15 | 10.00 | 10000.00 | 30
However, the result that I want is like this:
id | date | quantity| pricePerItem | #tot
50 | 2017-10-15 | 10.00 | 10000.00 | 10
1 | 2017-10-18 | 20.00 | 10000.00 | 30
How can I get the expected result?
EDIT
Simplified version of the problem can be found here: http://sqlfiddle.com/#!9/f6ad91/3
From what I understand from you, you want the cumulative total for each entry.
I suggest ditching the variable and relying on a subquery instead:
SELECT
scd.id,
scd.date,
scd.quantity,
scd.pricePerItem,
(SELECT SUM(scd1.quantity) FROM StockcardDetail AS scd1 WHERE scd1.stockcardId = scd.stockcardId AND scd1.date <= scd.date) AS total
FROM Stockcard
LEFT JOIN staff ON staff.branchId = stockcard.branchId
LEFT JOIN stockcarddetail AS scd ON scd.stockcardId = stockcard.id
WHERE staff.username = 'jemmy.h'
AND scd.quantity > 0
AND stockcard.productId = '98924a5f-6afb-11e7-8dd4-2c56dcbcb038'
ORDER BY scd.date ASC
The idea behind this is to make it select the sum of all entries prior (including the current one) for each entry.
As per my understanding, you should get the expected output from your query. But, you aren't getting your expected output, then other possible solution is (WITHOUT JOIN)
SET #tot:= 0;
SELECT
stockcarddetail.id,
stockcarddetail.date,
stockcarddetail.quantity,
stockcarddetail.pricePerItem,
#tot:=#tot + stockcarddetail.quantity as Total
FROM Stockcard
LEFT JOIN staff ON staff.branchId = stockcard.branchId
LEFT JOIN stockcarddetail ON stockcarddetail.stockcardId = stockcard.id
WHERE staff.username = 'jemmy.h' AND stockcarddetail.quantity > 0 AND stockcard.productId = '98924a5f-6afb-11e7-8dd4-2c56dcbcb038'
ORDER BY date ASC

Count (Select * Join) mysql query

I'm stuck on this for hours, I'm trying to COUNT how many subscribers are there in Group A, Group B, Group C for this particular query:
SELECT rh.id_subscriber, rh.bill_month, rh.bill_year,
(
SELECT tbl_gen_info.gen_data_03
FROM tbl_subscriber
LEFT JOIN tbl_gen_info ON tbl_subscriber.bill_area_code = tbl_gen_info.gen_data_01
WHERE rh.id_subscriber = tbl_subscriber.id_subscriber
) AS group_area
FROM tbl_reading_head AS rh
WHERE rh.id_soa_head IS NULL
AND rh.read_status <> 'Beginning'
AND rh.rec_status = 'active'
ORDER BY rh.id_subscriber
The sub-query gets the Group area gen_data_03 from tbl_gen_info
Tables contain this information:
tbl_gen_info
--------------------------------------------
| gen_category | gen_data_01 | gen_data_03 |
--------------------------------------------
| Area Code | Camacho St. | Group A |
--------------------------------------------
tbl_subscriber
----------------------------------
| id_subscriber | bill_area_code |
----------------------------------
| 1 | Camacho St. |
----------------------------------
tbl_reading_head
----------------------------------------------------------------------
| id_subscriber | id_soa_head | read_status | bill_month | bill_year |
----------------------------------------------------------------------
| 1 | NULL | Metered | 10 | 2017 |
----------------------------------------------------------------------
Notice that each id_subscriber has two (2) rows (one for electric, one for water). After grouping by id_subscriber:
GROUP BY rh.id_subscriber
I got this:
I tried adding COUNT before the sub-query making it:
COUNT(SELECT tbl_gen_info.gen_data_03 ...) AS group_area
but that doesn't work.
Use a subquery:
SELECT rh.group_area, COUNT(*)
FROM (SELECT rh.id_subscriber, rh.bill_month, rh.bill_year,
(SELECT tbl_gen_info.gen_data_03
FROM tbl_subscriber LEFT JOIN
tbl_gen_info
ON tbl_subscriber.bill_area_code = tbl_gen_info.gen_data_01
WHERE rh.id_subscriber = tbl_subscriber.id_subscriber
) as group_area
FROM tbl_reading_head rh
WHERE rh.id_soa_head IS NULL AND
rh.read_status <> 'Beginning' AND
rh.rec_status = 'active'
) rh
GROUP BY rh.group_area;

MySQL query for distinct rows on count

I have such query that gives me results about bestseller items from shops, at the moment it works fine, but now I want to get only one product from each shop so to have a distinct si.shop_id only one bestseller product from a shop
SELECT `si`.`id`, si.shop_id,
(SELECT COUNT(*)
FROM `transaction_item` AS `tis`
JOIN `transaction` as `t`
ON `t`.`id` = `tis`.`transaction_id`
WHERE `tis`.`shop_item_id` = `si`.`id`
AND `t`.`added_date` >= '2014-02-26 00:00:00')
AS `count`
FROM `shop_item` AS `si`
INNER JOIN `transaction_item` AS `ti`
ON ti.shop_item_id = si.id
GROUP BY `si`.`id`
ORDER BY `count` DESC LIMIT 7
and that gives mu a result like:
+--------+---------+-------+
| id | shop_id | count |
+--------+---------+-------+
| 425030 | 38027 | 111 |
| 291974 | 5368 | 20 |
| 425033 | 38027 | 18 |
| 291975 | 5368 | 12 |
| 142776 | 5368 | 10 |
| 397016 | 38027 | 9 |
| 291881 | 5368 | 8 |
+--------+---------+-------+
any ideas?
EDIT
so I created a fiddle for it
http://sqlfiddle.com/#!2/cfc4c/1
Now the query returns best selling products I want it to return only one product from shopso the result of fiddle should be
+----+---------+-------+
| ID | SHOP_ID | COUNT |
+----+---------+-------+
| 1 | 222 | 3 |
| 4 | 333 | 2 |
| 8 | 555 | 1 |
| 9 | 777 | 1 |
+----+---------+-------+
Possibly something like this:-
SELECT si.shop_id,
SUBSTRING_INDEX(GROUP_CONCAT(CONCAT_WS(':', si.id, sub1.item_count) ORDER BY sub1.item_count DESC), ',', 1) AS `count`
FROM shop_item AS si
INNER JOIN
(
SELECT tis.shop_item_id, COUNT(*) AS item_count
FROM transaction_item AS tis
JOIN `transaction` as t
ON t.id = tis.transaction_id
AND t.added_date >= '2014-02-26 00:00:00'
GROUP BY tis.shop_item_id
) sub1
ON sub1.shop_item_id = si.id
GROUP BY si.shop_id
ORDER BY `count` DESC LIMIT 7
The sub query gets the count of items for each shop. Then the main query concatenates the item id and the item count together, group concatenates all those for a single shop together (ordered by the count descending) and then uses SUBSTRING_INDEX to grab the first one (ie, everything before the first comma).
You will have to split up the count field to get the item id and count separately (the separator is a : ).
This is taking a few guesses about what you really want, and with no table declares or data it isn't tested.
EDIT - now tested with the SQL fiddle example:-
SELECT SUBSTRING_INDEX(`count`, ':', 1) AS ID,
shop_id,
SUBSTRING_INDEX(`count`, ':', -1) AS `count`
FROM
(
SELECT si.shop_id,
SUBSTRING_INDEX(GROUP_CONCAT(CONCAT_WS(':', si.id, sub1.item_count) ORDER BY sub1.item_count DESC), ',', 1) AS `count`
FROM shop_item AS si
INNER JOIN transaction_item AS ti
ON ti.shop_item_id = si.id
INNER JOIN
(
SELECT tis.shop_item_id, COUNT(*) AS item_count
FROM transaction_item AS tis
JOIN `transaction` as t
ON t.id = tis.transaction_id
AND t.added_date >= '2014-02-26 00:00:00'
GROUP BY tis.shop_item_id
) sub1
ON sub1.shop_item_id = si.id
GROUP BY si.shop_id
) sub2
ORDER BY `count` DESC LIMIT 7;

sum two rows and order by date / total

need some help to build a query, this is my current scheme:
users:
+----+------------+
| id | username |
+----+------------+
| 1 | rob |
| 2 | john |
| 3 | jane | <--- jane never has donated
| 4 | mike |
+----+------------+
donations:
+--------------------+------------+
| uid | amount | date |
+---------+----------+------------+
| 1 | 20 | 2013-10-10 |
| 2 | 5 | 2013-10-03 |
| 2 | 50 | 2013-09-25 |
| 2 | 5 | 2013-10-01 |
| 4 | 100 | 2012-10-01 | <-- past year
+---------+----------+------------+
Result I want:
+---------+-------------+---------+-------------+---------------+----------+
| id | username | amount | monthly | totalamount | total |
+---------+-------------+---------+-------------+ --------------+----------+
| 1 | rob | 20 | 1 | 20 | 1 |
| 2 | john | 60 | 3 | 60 | 3 |
| 3 | jane | 0 | 0 | 0 | 0 |
| 4 | mike | 0 | 0 | 100 | 1 |
+---------+-------------+-----------------------+---------------+----------+
This is my query:
SELECT
u.*,
COALESCE(sum(d.amount), 0) amount,
COUNT(d.uid) monthly,
COUNT(d.amount) as Total, <-- need to get sum all time donations and number of times donated
FROM users u
LEFT JOIN donations d
ON u.id = d.uid
AND (month(d.date), year(d.date)) = (month(CURDATE()), year(CURDATE()))
GROUP BY u.id ORDER BY u.id ASC
So i need to add 2 different sums from same data.
EDIT: http://sqlfiddle.com/#!2/20a974/9 schema and data
How I can do this?
For this we need to filter the data on the select and not on the join.
Remove this condition:
AND (month(d.date), year(d.date)) = (month(CURDATE()), year(CURDATE()))
and add this to the select:
SUM (CASE WHEN (month(d.date), year(d.date)) = (month(CURDATE()), year(CURDATE())) THEN 1 ELSE 0 END) as monthly
Edit:
whole query:
SELECT users.id, users.username,
COALESCE(sum(CASE WHEN (month(donations.date), year(donations.date)) = (month(CURDATE()), year(CURDATE())) THEN donations.amount ELSE 0 END), 0) monthly_sum,
COALESCE(sum(CASE WHEN (month(donations.date), year(donations.date)) = (month(CURDATE()), year(CURDATE())) THEN 1 ELSE 0 END), 0) monthly_amount,
COALESCE(sum(donations.amount), 0) total_sum,
count(*) total_amount
from users
left join donations
on donations.uid = users.id
group by users.id, users.username
http://sqlfiddle.com/#!2/20a974/20/0
For me the easiest way to think about the separately grouped information is to put it into separate queries and then just join the results back together. This is not likely to be the most efficient, but it helps to get something working.
select auo.id, auo.username,
coalesce(monthly_count, 0), coalesce(monthly_total, 0),
coalesce(total, 0), coalesce(total_amount, 0)
from aaa_users auo
left join (
select au.id as id, count(adm.amount) as monthly_count, SUM(adm.amount) as monthly_total
from aaa_users au join aaa_donations adm on au.id = adm.uid and adm.donate_date > GETDATE()-30
group by au.id
) as monthly on monthly.id = auo.id
left join (
select au.id as id, count(ady.amount) total, SUM(ady.amount) as total_amount
from aaa_users au join aaa_donations ady on au.id = ady.uid and ady.donate_date > getDate()-450
group by au.id
) as yearly on yearly.id = auo.id
As #CompuChip said, it's cleaner to just join to the donations table twice, but I have something wrong in my join logic as the values for john are getting duplicated. I think there would need to be a donations.id column to prevent the monthly and total donations from being combined. Anyway, here's an example even though it isn't working correctly
select au.id, au.username,
count(adm.amount), SUM(adm.amount) as monthly_total,
count(ady.amount), SUM(ady.amount) as total_amount
from aaa_users au
left outer join aaa_donations adm on au.id = adm.uid and adm.donate_date > GETDATE()-60
left outer join aaa_donations ady on au.id = ady.uid and ady.donate_date > getDate()-450
group by au.id, au.username
order by au.id, au.username
You can do another join to donations, giving it a different alias: LEFT JOIN donations d2 on d2.uid = u.id. Then sum over d2.amount for the last two fields, e.g.
SELECT u.*,
COALESCE(sum(d.amount), 0) amount,
COUNT(d.uid) monthly,
COUNT(d.amount) as Total,
COALESCE(sum(d2.amount), 0) amountAll,
COUNT(d2.uid) monthlyAll,
COUNT(d2.amount) as TotalAll
FROM users u
LEFT JOIN donations d ON u.id = d.uid AND (month(d.date), year(d.date)) = (month(CURDATE()), year(CURDATE()))
LEFT JOIN donations d2 ON u.id = d2.uid
GROUP BY u.id ORDER BY u.id ASC
