I'm trying to join 3 tables for a system to keep track of what comes in and out of my shop.
The first tables is as following. (Production)
id
Amount
Date
item id
next table is: (sales)
id
date
amount
customer id
amount
the last is: (waste)
id
date
amount
reason
I haven't really found a way to join those 3 tables without using a common value they could join on. I need to order them by date so I can see the history of my income and expenses. If the 3 different tables could come with a individual value like 3 for waste 2 for sales and 1 for production would also be great.
What you want is not a join of the tables but a union: http://dev.mysql.com/doc/refman/5.0/en/union.html
Something like
(SELECT 'production' as source, id, Amount AS amount, Date AS date FROM Production)
UNION
(SELECT 'sales' as source, id, amount, date FROM sales)
UNION
(SELECT 'waste' as source, id, amount, date FROM waste)
ORDER BY date;

I am still getting started learning Access.
I have 3 tables. Table one has Date as primary key and will have all dates. Tables 2 and 3 (Table 3 is mislabeled in the example image as a second Table 2) will both have 2 columns, Date and Amount. Tables 2 and 3 could have multiple rows with the same date (different amounts) and some may miss dates. I am looking for an output query that would have 1 row for every date in table 2 & 3 that has an amount (some dates may not have an amount in either table) and sums all those amounts for that date in 1 row. Below are example tables and the desired output query. Thanks so much for the newbie help!
I now have this code (Note that I have eliminated Table 1):
SELECT Table2.Dat, Sum(Table2.Amount) AS [Sum Of Amount], Sum(Table2.Tax) AS [Sum Of Tax]
FROM Table2
GROUP BY Table2.Dat;
UNION ALL SELECT Table3.Dat, Sum(Table3.Amount) AS [Sum Of Amount], Sum(Table3.Tax) AS [Sum Of Tax]
FROM Table3
GROUP BY Table3.Dat;
This sums the amounts from same dates for each seperate table, but does not sum the dates for both tables. I imagine it is another GROUP function but I have not been successful in forming it correctly.
Current Results from code above
Try below query.
SELECT tt.mDate AS TransactionDate, Sum(tt.SumOfAmount) AS AmountTotal
FROM (SELECT Table2.tDate as mDate, Sum(Table2.Amount) AS SumOfAmount
FROM Table2
GROUP BY tDate
UNION
SELECT Table3.tDate As mDate, Sum(Table3.Amount) AS SumOfAmount
FROM Table3
GROUP BY tDate) AS tt
GROUP BY tt.mDate;
Customer table with purchases in a date range
Having some challenge doing this.
Select all customers that made more than 2 purchases in an hour
starting from a given datetime eg.2016-01-01.13:00:00
Select all customers that made more than 2 purchases in a a day(24
hours) starting from a given datetime eg. 2016-01-01.15:30:05
Select count(name) from cust_table where count(name)
IN (BETWEEN (2016-01-01.13:00:00, 2016-01-01.14:00:00))
You need to get the identifiers (usernames or ID or so) for all users who have made more than two purchases. Something like the following should work:
SELECT name FROM purchases GROUP BY name HAVING COUNT(name) > 2
To get such rows where the purchases were made between some dates, just add a WHERE clause, so it becomes something like this
SELECT name FROM purchases WHERE pdate BETWEEN (2016-01-01.13:00:00) AND (2016-01-01.14:00:00) GROUP BY name HAVING COUNT(name) > 2
What this does is group the table rows by name with purchases between the specified dates. It then filters the groups using the HAVING COUNT(name) > 2 clause to retrieve only rows that appear more than twice.
I have these two tables
The first one is expenses table and the second one is expensename
Exp_Type(first table) is the Expense name(second table) as 2 is Food
I am trying to group expense according to expense type and get data between certain dates.
This is what i have tried, but it wont work.
select
(select
(select name from EXPENSENAME where id=EXP_TYPE)as ExpenseType,
sum(PRICE) as cost
from EXPENSES WHERE USERID=1 GROUP BY EXPENSES.EXP_TYPE),
[date]
from EXPENSES where [date] BETWEEN '10-09-2015' and '10-18-2015 23:59:59'
And
select
(select name from EXPENSENAME where id=EXP_TYPE)as ExpenseType,
sum(PRICE) as cost,
date
from EXPENSES WHERE USERID=1 and DATE BETWEEN '01/10/2015' and '29/10/2015' GROUP BY EXPENSES.EXP_TYPE
With out date, i am getting result by this query but i need the same data between certain dates,please help
select
(select name from EXPENSENAME where id=EXP_TYPE)as ExpenseType,
sum(PRICE) as cost
from EXPENSES WHERE USERID=1 GROUP BY EXPENSES.EXP_TYPE
you want to join the tables together
SELECT en.name as ExpenseType, SUM(e.price) as cost
FROM expenses e
JOIN expensename en ON en.id = e.exp_type
WHERE e.date BETWEEN '10-09-2015' and '10-18-2015'
GROUP BY en.name
this should give you the cost per name
the current query you have is TERRIBLE... and this is why
SELECT (SELECT ... FROM ... WHERE ... ) as ...
this is creating a correlated subquery which is executing once for every row of the parent select. meaning if you have a table with 4 rows in it (SELECT ... FROM ... WHERE ... ) will execute 4 times scanning 16 rows (assuming its from the same table) in general that is a really really bad way to get data... if you have a million rows... well do the math, its a bad idea
I have 2 tables.ms_expese and track_expense.Using this table generate a fact table
I want the expense_name in ms_expense,expense_amount from track_expense.
I want to get the sum of expense_amount for a particular expense_name based on date.The date in the order of 1,2...12 as month id
SELECT DATE_Format(a.date,'%b') as month_id,b.expense_name AS expense_type, sum(a.expense_amount) AS expense_amount FROM ms_expense b JOIN track_expense a on a.`expense_id`=b.`expense_id` group by DATE_Format(a.date,'%b')
how to put the month id in the order of 1,2,..12 and my date format y-m-d
I get the month in apr,aug and so on but i need jan as 1,feb as 2
I have 25 expenses(expense name).In this query i got the total expense amount of first expense only.I want the total expense of all expenses in every month
CREATE TABLE fact AS
(<your select query>)
Your select query can be in the following form
SELECT MONTH(date)as month_id,expense_name,sum(expense_amount)
FROM ms_expense JOIN track_expense using (expense_id)
group by expense_name,MONTH(date)
I am trying to count sales made by a list of sales agents, this count is made every few minutes and updates a screen showing a 'sales leader board' which is updates using a Ajax call in the background.
I have one table which is created and populated every night containing the agent_id and the total sales for the week and month. I create a second, temporary table, on the fly which counts the sales for the day.
I need to combine the two tables to create a current list of sales for all agents in agent_count.
Table agent_count;
agent_id (varchar),
team_id (varchar),
name (varchar),
day(int),
week(int),
month(int)
Table sales;
agent_id (varchar),
day(int)
I can't figure out how to combine these tables. I think I need to use a join as all agents must be returned - even if they don't appear in the agent_count table.
First I make a simple call to get the week and month totals for all agents
SELECT agent_id, team_id, name, week, month FROM agent_count;
the I create a temporary table of todays sales, and then I count the sales for each agent for the day
CREATE TEMPORARY TABLE temp_todays_sales
SELECT s.id, s.agent_id
FROM sales s
WHERE DATEDIFF(s.uploaded, NOW()) = 0
AND s.valid = 1;
SELECT tts.agent_id, COUNT(tts.id) as today
FROM temp_todays_sales tts
GROUP BY tts.agent_id;
What is the best/easiet way to combine these to end up with a resultset such as
agent_id, team_id, name, day, week, month
where week and month also include the daily totals
thanks for any help!
Christy
SELECT s.agent_id, ac.team_id, ac.name,
s.`day` + COALESCE(ac.`day`, 0) AS `day`,
s.`day` + COALESCE(ac.`week`, 0) AS `week`,
s.`day` + COALESCE(ac.`month`, 0) AS `month`
FROM sales s
LEFT JOIN
agent_count ac
ON ac.agent_id = s.agent_id
team_id and name will be NULL if there is no record in agent_count for an agent.
If the agents can be missing from both tables, you normally would need to make a FULL JOIN but since MySQL does not support the latter you may use its poor man's substitution:
SELECT agent_id, MAX(team_id), MAX(name),
SUM(day), SUM(week), SUM(month)
FROM (
SELECT agent_id, NULL AS team_id, NULL AS name, day, day AS week, day AS month
FROM sales
UNION ALL
SELECT *
FROM agent_count
) q
GROUP BY
agent_id
