This is my sql query to get the following table below :
select c.name, s.company, p.qty, p.qty * p.price as Total
from client c, purchase p, stock s
where c.clno = p.clno AND s.company = p.company
group by c.name, s.company, p.qty, p.qty * p.price
order by sum(p.qty) desc
The output of the above query looks like this :
Name | Company | Qty | Total
John ABC 12 100
Bob XYZ 10 150
John ABC 5 50
Bob XYZ 20 250
Bob XYZ 2 20
Nav QRS 10 150
John ABC 10 150
I want to have the query to get the output as the following :
Name | Company | Qty | Total
John ABC 27 300
Bob XYZ 32 420
Nav QRS 10 150
As of now your query uses GROUP BY but does not actually aggregates data. You want to GROUP BY name and company, and SUM the quantities and amounts, like :
select c.name, s.company, SUM(p.qty), SUM(p.qty * p.price) as Total
from client c
inner join purchase p on c.clno = p.clno
inner join stock s on s.company = p.company
group by c.name, s.company
order by Total desc
Other remarks regarding your query :
always use explicit joins instead of implicit ones
you can use column aliases in the ORDER BY clause (here, Total ; this can make the query easier to read

EDIT
I tried this but it gives me only bob and sum of all columns instead of separate sum of customers
SELECT customers.name, SUM(orders.order_amount) FROM `orders` INNER JOIN customers WHERE orders.customer_id = customers.customer_id;
Joining condition must be on ON clause, not in WHERE.
You must specify for what group the sum must be calculated.
SELECT customers.name, SUM(orders.order_amount)
FROM `orders`
INNER JOIN customers ON orders.customer_id = customers.customer_id
GROUP BY customers.name;

The result which I want:

Explanation: I want to count how many users have book1 and how much total they spend on a date between 2020-02-01 - 2020-02-03.
Now how the query should look like?
I am using MySQL version 8.
I have tried:
SELECT
count(*), sum(amount_spend) as total_amount_spend
FROM
(select sum(amount_spend) as amount_spend
FROM expanses
LEFT JOIN books ON books.user_id = expanses.user_id WHERE books.book_name ='book1 GROUP BY expanses.user_id) src'
And the result is wrong because I am getting a higher amount_spend than in my table result above. I think while joining the table there are some duplicates but I do not know how to fix them.
I want to count how many users have book1 and how much total they spend on a date between 2020-02-01 - 2020-02-03.
I am thinking:
select count(*), sum(e.amount_spent)
from user_books ub join
expenses e
on ub.user_id = e.user_id
where book_name = 'book1';
Note: This assumes that user_books doesn't have duplicate rows.
FIDDLE
You miss the date part in your code.
SELECT
count(*), sum(amount_spent) as total_amount_spend
FROM
(select sum(amount_spent) as amount_spent
FROM expanses
LEFT JOIN books ON books.user_id = expanses.user_id
WHERE books.book_name ='book1'
and expanses.date between '2020-02-01' and '2020-02-03'
GROUP BY expanses.user_id) src;
will do a job.
Please note that you don't need to have left join here (unless you're sure that it may happen that no expenses at all for given user will be), and you don't need to have grouping in subquery. So your query could look like:
select count(distinct expanses.user_id), sum(amount_spent) as amount_spent
from expanses
inner join books on books.user_id = expanses.user_id
where books.book_name ='book1'
and expanses.date between '2020-02-01' and '2020-02-03';
I have 3 table relation using MYSQL;
Example first as riders table:
bib | series_id | point
202 3 200
219 3 140
202 2 200
219 2 110
10 1 90
Example second as series table:
series_id | series_no | season_id
1 1 2
2 2 1
3 1 1
Example third as seasons table:
season_id | year
1 2015
2 2016
How to GROUP_CONCAT point correctly? I'm trying like this
SELECT riders.bib, seasons.year, GROUP_CONCAT(DISTINCT riders.point ORDER BY series.series_no DESC) AS seriPoint
FROM series, riders, seasons
GROUP BY riders.bib
I'm getting output seriPoint for bib: 202 is 200 and bib: 219 is 140,110 when I'm using DISTINCT output like that. But when I'm not using DISTINCT getting output seriPoint for bib: 202 is 200,200,200,200 and bib: 219 is 140,110,140,110. What I want is output seriPoint for bib: 202 is 200,200 and bib: 219 is 140,110.
ADD: please help to add filter too, for season_id when different season_id its to be different row.
yes you are getting correct output since you have used DISTINCT. BTW, you should change your query to use proper JOINS
SELECT riders.bib,
seasons.year,
GROUP_CONCAT(DISTINCT riders.point ORDER BY series.series_no DESC) AS seriPoint
FROM riders
JOIN series ON series.series_id = riders.series_id
JOIN seasons ON series.season_id = seasons.season_id
GROUP BY riders.bib;
(OR) you can get the grouping first and then perform join like
select seasons.year, xx.bib, xx.seriPoint
FROM series
JOIN (
select series_id, bib
group_concat(point) as seriPoint
from riders
group by bib ) xx ON series.series_id = xx.series_id
JOIN seasons ON series.season_id = seasons.season_id
order by xx.seriPoint;
I have the following tables:
table part_list:
part_number | description | type
100 blablabla blabla
table part_list_supplier:
part_id | artikel
100 100100
100 200100
and I have this query:
select part_list.part_number, part_list.description, part_list.type, group_concat(coalesce(part_list_supplier.artikel, "nothing")) as "artikel"
from part_list
left join part_list_supplier on (part_list.part_number = part_list_supplier.part_id)
group by part_list.part_number;
this is the result:
part_number | description | type | artikel
100 blablablabla blabla 100100,200100
but I want to show the total stock per partnumber behind it. table receipt:
Number | import
100 5
100 10
table sales:
Number | sold
100 5
this is my query for one table:
SELECT SUM(sold) AS sold
FROM sales WHERE number = '".$partnumber.”'
but I want to calculate the stock per number and that must be shown behind the other results.
the full result:
part_number | description | type | artikel | stock
100 blablablabla blabla 100100,200100 10
The stock should be 10 because the total number of imports is 15 (5 + 10) and the total number of sales is 5.
I broke this up into pieces to solve it. I started by writing two queries, one that counted total receipt and one that counted total sales:
SELECT r.number, SUM(r.import) AS totalIn
FROM receipt r
GROUP BY r.number;
SELECT s.number, SUM(s.sold) AS totalOut
FROM sales s
GROUP BY s.number;
Then, I used those as two subqueries of a join to get the stock:
SELECT r.number, totalIn - totalOut AS stock
FROM(
SELECT r.number, SUM(r.import) AS totalIn
FROM receipt r
GROUP BY r.number) r
JOIN(
SELECT s.number, SUM(s.sold) AS totalOut
FROM sales s
GROUP BY s.number) s ON s.number = r.number;
Once I verfied this gave the proper stock, I was able to include those subqueries into your original query to build this:
SELECT pl.part_number, pl.description, pl.type,
GROUP_CONCAT(COALESCE(pls.artikel, "Nothing.")) AS artikel,
r.totalIn - s.totalOut AS stock
FROM part_list pl
LEFT JOIN part_list_supplier pls ON pls.part_id = pl.part_number
JOIN(
SELECT number, SUM(import) AS totalIn
FROM receipt
GROUP BY number) r ON r.number = pl.part_number
JOIN(
SELECT number, SUM(sold) AS totalOut
FROM sales
GROUP BY number) s ON s.number = r.number
GROUP BY pl.part_number;
Here is an SQL Fiddle example.
I may not be understanding your question properly, but can't you just add sum(sales.sold) to your select statement and join the sales table? E.g.:
select part_list.part_number, part_list.description, part_list.type, group_concat(coalesce(part_list_supplier.artikel, "nothing")) as "artikel", sum(sales.sold)
from part_list
left join part_list_supplier on (part_list.part_number = part_list_supplier.part_id)
left join sales on (part_list.part_number = sales.number
group by part_list.part_number;
I was successful in writing the query that lists salesmen that did sell to a particular customer, but not those that have not. I suspect it is because the same salesmen that sold to the specific customer, also sold to other customers.
select a.name from salesperson a inner join orders b on
a.salesperson_id = b.salesperson_id where cust_id="4";
I was thinking that modifying the same query like this would do the trick:
.... a.salesperson_id <> b.salesperson_id where cust_id="4";
But the result lists all the salesmen. This is most likely due to the fact that the same salesmen that were returned in the original query, also sold to other customers
The 3 tables look like this:
Salesperson table
salesperson_ID, Name, Age, Salary
1 Abe 61 140000
2 Bob 34 44000
5 Chris 34 40000
7 Dan 41 52000
8 Ken 57 115000
11 Joe 38 38000
Customer table
cust_ID, Name, City Industry Type
4 faralon sacramento H
6 Apple cupertino S
7 Honda NY B
9 Kolb Oshkosh B
Orders table
Number, Order_date, cust_id, salesperson_id, Amount
10 8/2/1996 4 2 540
20 1/30/1999 4 8 1800
30 7/14/1995 9 1 460
40 1/29/1998 7 2 2400
50 2/3/1998 6 7 600
60 3/2/1998 6 7 720
70 5/6/1998 9 7 150
Any help would be greatly appreciated. ~Alpinehyker
You can do something like this:
select a.name from salesperson a
left join orders b on a.salesperson_id = b.salesperson_id and b.cust_id="4"
where b.Number is null
So, get all salepersons, left join to orders for customer 4, and return only rows where there is no such order.
I am assuming that Number is the primary key for Orders, or at least not null.
All salespeople who have NOT sold to customer_ID 4:
SELECT s.Name FROM Salesperson AS s
LEFT JOIN Orders AS o
ON s.salesperson_ID = o.salesperson_ID
WHERE o.customer_ID <> 4
GROUP BY o.salesperson_ID;
Perhaps this will work
SELECT
s.*
FROM `Salesperson` AS s
LEFT JOIN `Orders` AS o ON o.`salesperson_id` = s.`salesperson_ID`
WHERE
o.`cust_id` NOT IN (4)
GROUP BY s.`salesperson_ID`;
Answer to your 2nd question:
SELECT
COUNT(*) AS num_of_orders
,s.`Name`
FROM `Salesperson` AS s
LEFT JOIN `Orders` AS o ON o.`salesperson_id` = s.`salesperson_ID`
GROUP BY s.`salesperson_ID`
HAVING num_of_orders >= 2;
...and 3rd question. (assuming you have your highAchiever table ready)
INSERT INTO `highAchiever`
(`Name`,`Age`)
SELECT
`Name`
,`Age`
FROM `Salesperson`
WHERE
`Salary` >= 100000;
