MySQL select for global sales report - mysql

I have a web app in .Net with Reportviewer and I use as sourcedata of reportviewer MySql query, I need to make a global sales report I have this Table sales:
|IdSale|Number|Date|Price| etc...
(The important part of my problem is the next, i need to calculate the sum of price for each row with the same Number. Why? Well the Number datafield is the receipt or bill, so I can have one sale for the receipt / bill number 6 and i selled 2 items:
|IdSale|Number| Date |Price|
| 1 | 6 |20/08 | 50€|
| 2 | 6 |20/08 | 10€|
----------------------------
So i need to get the sum of that but, with the others Numbers i mean i can do that with this query:
Select distinct sales.Number, sales.Date, SUM(sales.Price) as 'Importe',
from sales where number = 6;*
and return
|Number|Date|Importe(price)|
| 6 |20/8| 100€ |
That's ok but when i have this
|IdSale|Number| Date |Price|
| 1 | 6 |20/08 | 50€|
| 2 | 6 |20/08 | 10€|
| 3 | 7 |20/08 | 30€|
| 4 | 8 |20/08 | 20€|
----------------------------
I neet to get this output
|Number|Date|Importe(price)|
| 6 |20/8| 100€ |
| 7 |20/8| 30€ |
| 8 |20/8| 20€ |
But the only thing i made is using this query
Select distinct sales.Number, sales.Date, SUM(sales.Price) as 'Importe',
from sales where number >= 0;
|Number|Date|Importe(price|
| 2 |20/8| 150€ |
So im getting the sum of all but i just need the sum of each row with the same Number can i do this?

Are you just looking for group by?
Select s.Number, s.Date, SUM(s.Price) as Importe,
from sales s
group by s.Number, s.Date;

Creating a crosstab query in MySQL

I have a MySQL table that tracks certain totals by both hour of the day and various locations. I am trying to create a query that will total not only each column, but also each row. The query I have so far totals each column, but I can't figure out how to get a total for each row as well.
This is my query:
SELECT * FROM
(SELECT IFNULL(hour,"Total") as hour, SUM(location1), SUM(location2), SUM(location3), SUM(location4), SUM(location), FROM counts WHERE ay = 'AY1617' GROUP BY hour WITH ROLLUP) as crossdata
ORDER BY FIELD (hour,'8:00am','9:00am','10:00am','11:00am','12:00pm','1:00pm','2:00pm','3:00pm','4:00pm','5:00pm','6:00pm','7:00pm','8:00pm','9:00pm','10:00pm','11:00pm')
This is ultimately what I want the output to look like:
hour location1 location2 location3 location4 totals
8am 4 3 2 1 10
9am 1 2 2 1 6
10am 2 3 2 3 10
totals 7 8 6 5 26
How can I achieve this?
For what it's worth, this is not a crosstab query. You aren't pivoting rows to columns.
I tried this query and got the result you want:
SELECT IFNULL(hour, 'Total') AS hour,
SUM(location1) AS location1,
SUM(location2) AS location2,
SUM(location3) AS location3,
SUM(location4) AS location4,
SUM(location1)+SUM(location2)+SUM(location3)+SUM(location4) AS totals
FROM counts
WHERE ay = 'AY1617'
GROUP BY hour WITH ROLLUP;
You should really use the TIME data type instead of strings for the hour. Then it just sorts correctly.
+----------+-----------+-----------+-----------+-----------+--------+
| hourt | location1 | location2 | location3 | location4 | totals |
+----------+-----------+-----------+-----------+-----------+--------+
| 08:00:00 | 4 | 3 | 2 | 1 | 10 |
| 09:00:00 | 1 | 2 | 2 | 1 | 6 |
| 10:00:00 | 2 | 3 | 2 | 3 | 10 |
| Total | 7 | 8 | 6 | 5 | 26 |
+----------+-----------+-----------+-----------+-----------+--------+

SQL insert into select from - insert the id instead of the data

I need to populate my fact table with data from lds_placement table. I have selected the records and here is what it looks like:
fk1_account_id | fk3_job_role_id | salary | no_of_placements | YEAR
---------------------------------------------------------------------
10 | 3 | 165000 | 5 | 2010
10 | 3 | 132000 | 4 | 2011
10 | 3 | 132000 | 4 | 2012
20 | 2 | 990000 | 3 | 2010
20 | 2 | 132000 | 2 | 2011
20 | 2 | 132000 | 2 | 2012
I want to insert time_id from a different table called time_dim into the column year and not the actual year itself.
The time_dim table looks like this:
time_id | year
---------------
5 | 2015
1 | 2013
2 | 2010
3 | 2014
4 | 2012
6 | 2011
I need to insert into "year" column is actually:
year
2
6
4
2
6
4
Please give me the way to insert time_id instead of year in the table.
Here is the code I used to select the top-most table.
SELECT
fk1_account_id,
fk3_job_role_id,
Sum(actual_salary) AS salary,
Count(1) AS no_of_placements,
MAX(EXTRACT(YEAR FROM plt_estimated_end_date)) AS year
FROM lds_placement
GROUP BY fk1_account_id, fk3_job_role_id, EXTRACT(YEAR FROM plt_estimated_end_date)
ORDER BY fk1_account_id;
Use a left join if you want to capture records where year doesn't exist in time_dim. Else use inner_join.
select t.fk1_account_id,t.fk3_job_role_id,t.salary,t.no_of_placements
,d.time_id
from
(SELECT fk1_account_id, fk3_job_role_id, Sum(actual_salary) as salary, Count(1) as no_of_placements, MAX(EXTRACT(YEAR FROM plt_estimated_end_date)) AS YEAR
FROM lds_placement
GROUP BY fk1_account_id, fk3_job_role_id, EXTRACT(YEAR FROM plt_estimated_end_date)
)t
left join time_dim d
on t.year=d.year
order by t.fk1_account_id

SQL query SUM() AND GROUP BY

I have a MySQL table like this:
acco_id | room_id | arrival | amount | persons | available
1 | 1 | 2015-19-12 | 3 | 4 | 1
1 | 2 | 2015-19-12 | 1 | 10 | 1
1 | 1 | 2015-26-12 | 4 | 4 | 1
1 | 2 | 2015-26-12 | 2 | 10 | 1
2 | 3 | 2015-19-12 | 2 | 6 | 0
2 | 4 | 2015-19-12 | 1 | 4 | 1
What im trying to achieve is a single query with a result like:
acco_id | max_persons_available
1 | 22
2 | 4
I tried using a GROUP BY accommodation_id using a query like:
SELECT
accommodation_id,
SUM(amount * persons) as max_persons_available
FROM
availabilities
WHERE
available = 1
GROUP BY
accommodation_id
Only now the result of acco_id uses all arrival dates. When I add arrival to the query no more unique acco_id's.
Does anyone know a good Single SQL which can use the table indexes?
If I'm understanding the question correct (the last part is a bit confusing). You want to have the accomodation id and numbers as you have now but limited to specific arrival dates.
If so the following statement should do exactly that as it is not necessary to put arrival into the select if you "just" use it in the where statement. As else you would need to put it into the group by and thus have non unique accomodation id's.
SELECT
accommodation_id,
SUM(amount * persons) as max_persons_available
FROM
availabilities
WHERE
available = 1 and arrival >= '2015-12-19' and arrival < '2015-10-26'
GROUP BY
accommodation_id
I guess (reading your question) what you are looking for is this but im not sure as your question is a bit unclear:
SELECT
accommodation_id,
arrival,
SUM(amount * persons) as max_persons_available
FROM
availabilities
WHERE
available = 1
GROUP BY
accommodation_id, arrival

a query that returns a single row for each foreign key

I have a table of routines. In this table, I have the column "grade" (which is not mandatory), and the column "date". Also, I have a number of days and an array of ids of users. I need a query that returns me the last routine that have a value != null for "grade" column and datediff(current_date,date) >= number_of_days for each id in the array and make an average of all these values.
e.g.
today = 2014/10/15
number_of_days = 10
ids(1,3)
routines
id | type | date | grade | user_id
1 | 1 | 2014-10-10 | 3 | 1
2 | 1 | 2014-10-04 | 3 | 1
3 | 1 | 2014-10-01 | 3 | 1
4 | 1 | 2014-09-24 | 2 | 1
5 | 1 | 2014-10-10 | 2 | 2
6 | 1 | 2014-10-04 | 3 | 2
7 | 1 | 2014-10-01 | 3 | 2
8 | 1 | 2014-09-24 | 1 | 2
9 | 1 | 2014-10-10 | 1 | 3
10 | 1 | 2014-10-04 | 1 | 3
11 | 1 | 2014-10-01 | 1 | 3
12 | 1 | 2014-09-24 | 1 | 3
In this case, my query would return an avg between "grade" of row id #2 and #10
I think you're saying that you want to consider rows having non-null values in the grade column, a date within a given number of days of the current date, and one of a given set of user_ids. Among those rows, for each user_id you want to choose the row with the latest date, and compute an average of the grade columns for those rows.
I will assume that you cannot have any two rows with the same user_id and date, both with non-null grades, else the question you want to ask does not have a well-defined answer.
A query along these lines should do the trick:
SELECT AVG(r.grade) AS average_grade
FROM
(SELECT user_id, MAX(date) AS date
FROM routines
WHERE grade IS NOT NULL
AND DATEDIFF(CURDATE(), date) >= 10
AND user_id IN (1,3)
GROUP BY user_id) AS md
JOIN routines r
ON r.user_id = md.user_id AND r.date = md.date
Note that in principle you need a grade IS NOT NULL condition on both the inner and the outer query to select the correct rows to average, but in practice AVG() ignores nulls, so you don't actually have to filter out the extra rows in the outer query.

SQL COUNT DISTINCT values tied to record via JOIN

I have 2 tables:
stock
StockID | ItemName
1 | hat
2 | hammer
3 | banana
4 | elephant
5 | book
and Basket
BasketID | StockID | Quantity
1 | 3 | 5
2 | 2 | 20
3 | 1 | 7
4 | 2 | 60
5 | 5 | 23
6 | 1 | 17
7 | 3 | 3
8 | 4 | 6
9 | 3 | 1
10 | 2 | 1
11 | 2 | 13
I'm trying to make an SQL query which out puts the StockID, ItemName, Total Quantity Sold, and the Number of Orders that Item had.
I have this:
SELECT stock.StockID, stock.ItemName, SUM( basket.Quantity ) AS QuantitySold
FROM stock
JOIN basket ON stock.StockID = basket.StockID
GROUP BY stock.Itemname
ORDER BY stock.StockID
LIMIT 0 , 30
Which works fine, but when I try adding:
COUNT (DISTINCT basket.BasketID)
I just get a message saying I have a Syntax Error.
I am fairly new to all this, so sorry if my logic is wrong, but shouldn't that just count the distinct values tied to stockID, as it does pretty much that with the SUM of quantity sold, where it locates all the basket.Quantity values tied to the stockID in the basket table.
All help much appreciated -Tom
Not sure if this is the full answer to your question, but I don't think that in MySQL you can have a space between the function name and the leading parenthesis like you do with COUNT.
