i want to make some daily report which order by date.
i want this data can increase every day.
Date qty QP
2010-09-01 10 10
2010-09-02 3 13 (it means result QP from 2010-09-01 accumulate with 2010-09-02)
2010-09-03 8 21
this is the 1st code:
SELECT Date, SUM(number) AS qty FROM calc GROUP BY Date
how do i do to show "QP" if for actually i dont need to show "qty" field(automatic count) just show Date and QP but it still can count?
SET #r := 0;
SELECT date, #sum := SUM(number) AS qty, #r := #r + #sum AS qp
FROM calc
GROUP BY
date
This example will help you for sure:
MySQL select "accumulated" column

SELECT value FROM table produces this result:
1
5
8
3
But I want to get the single values and the sum of all the output
1 17
5 17
8 17
3 17
SELECT value,SUM(value) FROM table produces just only
1 17
How can I somehow "ungroup" my results?
Thanks for your answers.....
Use a sub-query:
SELECT value, (SELECT SUM(value) FROM table) AS sValue
FROM table
You can alternatively use a CROSS JOIN:
SELECT value, sValue
FROM mytable
CROSS JOIN (SELECT SUM(value) AS sValue FROM mytable) AS t
If you don't need the SUM on every row you could use user variables:
SELECT value, #sum := #sum + value AS cumulative
FROM table1
JOIN (SELECT #sum := 0) init
WHERE ...
This will give you a cumulative sum and the last row will have the correct total.
Alternatively, assuming this is part of an application and you are looping through the results to display them, it may be easier to perform the calculation in the application logic.
Is there a way to capture a cummulative sum with a reset condition in mySQL? The use case for this is a simple cash register table
id transactionType value CurrentBalance
1 purchase 10 10
2 sale -10 0
3 RESET 20 20
4 purchase 10 30
5 sale -10 20
6 sale 10 30
7 sale -20 10
The answer from here is a good starting point but I don't see how to extend it:
Create a Cumulative Sum Column in MySQL
SELECT t.id,
t.count,
#running_total := #running_total + t.value AS CurrentBalance
FROM TABLE t
JOIN (SELECT #running_total := 0) r
ORDER BY t.id
NOTE: basically the idea is to reset the cumulative sum each time a reset is hit. Ideally I am trying to have an on update/insert trigger which will update the entire CurrentBalance column taking into account RESETs. This is a small table so I don't mind updating the whole table in exchange for something simple.
All this requires is some simple conditional logic:
SELECT t.id, t.count,
#running_total := if(transactionType = 'RESET', t.value,
#running_total + t.value
) as CurrentBalance
FROM TABLE t JOIN
(SELECT #running_total := 0) params
ORDER BY t.id;
I am using MySQL and need to display the sum of all the previous values, including the current row, for each row.
date | val | total
------------------
15M | 20 | 20
17M | 15 | 35
1APR | -5 | 30
-------------------
So, in the database I only have the date and the val for each date. I currently use SELECT date, val FROM table ORDER BY DATE ASC. How can I also add the total column? I guess I would use a SUM query, but how do I add the sum for every row?
In case you can use a variable, you can easily calculate cumulative sum
this way
set #csum := 0;
select date, val, (#csum := #csum + val) as cumulative_sum
from table
order by date DESC;
EDIT There is a way to define your variable in a join
select t.date, t.val, (#csum := #csum + t.val) as cumulative_sum
from table t
join (select #csum := 0) r
order by date DESC;
i've tried some other topics for this but couldn't get answers that meet my requirement so posting a new question. sorry bout this.
i'm trying to query on mysql to get a 'sum' data until it reaches the defined value. like
from my table 'purchase', for each 'sid' starting from the last row, i need sum of 'pqty' until the result equals a value from string (but to try i've given a certain value).
let me define with the rows from my table---
the rows for 'sid=1' from 'purchase' are like this---
date pqty prate pamt
2014/04/29 5 38000 190000
2014/05/04 1 38000 38000
2014/05/13 20 35000 700000
2014/05/19 1 38000 38000
from this row, starting from the last row i want to 'sum(pqty) until it reaches 19(for now). it is achieved from adding last 2 rows(for 19). and stop sum here and return valus or sum of 'pqty', 'prate' and 'pamt'. to achieve this i tried the following according to example found on this forum.
SELECT date, pqty, #total := #total + pqty AS total
FROM (purchase, (select #total :=0) t)
WHERE #total<19 AND sid = $sid ORDER BY date DESC
but it's not working for me. please guide me through this. also suggest something else if this is not the good technique for my purpose.
thankz in advance.....
Not 100% certain, but I think both of these work...
SELECT x.*, SUM(y.pqty) FROM purchase x
JOIN purchase y
ON y.date >= x.date
GROUP
BY x.date
HAVING 19 BETWEEN SUM(y.pqty)-x.pqty AND SUM(y.pqty)
OR 19 >= SUM(y.pqty);
SELECT a.*
FROM
( SELECT x.*, #i := #i+pqty i
FROM purchase x
, (SELECT #i:= 0) var
ORDER
BY x.date DESC
) a
WHERE 19 BETWEEN a.i-a.pqty AND a.i
OR 19 >= a.i;
ID int(11) (NULL) NO PRI (NULL)
CREATED_DATE datetime (NULL) YES (NULL)
As mentioned above is some of field of my table 'User'.I want number of total user and cumulative count grouped on date.I used below query in mysql.
SELECT q1.CREATED_DATE,q1.NO_OF_USER, (#runtot := #runtot + q1.NO_OF_USER) AS CUMM_REGISTRATION FROM (SELECT date(CREATED_DATE) AS CREATED_DATE,
COUNT(ID) AS NO_OF_USER FROM USER,(SELECT #runtot:=0) AS n GROUP BY CREATED_DATE ORDER BY CREATED_DATE) AS q1
Which is working fine.Now I want one more additional data which will be 'CUMULATIVE USER COUNT SINCE 1 AUGUST '.Is it possible to fetch this modifying above query or its better to handle in code?Please suggest.
You can do this by adding another variable and doing it in the code:
SELECT q1.CREATED_DATE, q1.NO_OF_USER,
(#runtot := #runtot + q1.NO_OF_USER) AS CUMM_REGISTRATION,
#Aug1tot := if(CREATED_DATE >=date('2013-08-01'), #Aug1tot + q1.NO_OF_USER, NULL) as CUMM_SINCE_Aug1
FROM (SELECT date(CREATED_DATE) AS CREATED_DATE,
COUNT(ID) AS NO_OF_USER
FROM USER cross join
(SELECT #runtot:=0, #Aug1tot := 0) n
GROUP BY date(CREATED_DATE)
ORDER BY date(CREATED_DATE);
) AS q1
I guess you have some function called MONTH(yourDate) in mySQL, where MONTH(15-Aug-2013) will return 8.
You could either group your results per MONTH(yourDate), or filter your original data for MONTH(yourDate) = 8. Be careful if your data runs along multiple years, as all dates where month = 8 will be cumulated. You could then add a sorting / filtering critera based on YEAR(yourDate)
