I searched forum for 1h and didn't find nothing similar.
I have this problem: I want to compare two colums ID and DATE if they are the same in both tables i want to put number from table 2 next to it. But if it is not the same i want to fill yearly quota on the date. I am working in Access.
table1
id|date|state_on_date
1|30.12.2013|23
1|31.12.2013|25
1|1.1.2014|35
1|2.1.2014|12
2|30.12.2013|34
2|31.12.2013|65
2|1.1.2014|43
table2
id|date|year_quantity
1|31.12.2013|100
1|31.12.2014|150
2|31.12.2013|200
2|31.12.2014|300
I want to get:
table 3
id|date|state_on_date|year_quantity
1|30.12.2013|23|100
1|31.12.2013|25|100
1|1.1.2014|35|150
1|2.1.2014|12|150
2|30.12.2013|34|200
2|31.12.2013|65|200
2|1.1.2014|43|300
I tried joins and reading forums but didn't find solution.
Are you looking for this?
SELECT id, date, state_on_date,
(
SELECT TOP 1 year_quantity
FROM table2
WHERE id = t.id
AND date >= t.date
ORDER BY date
) AS year_quantity
FROM table1 t
Output:
| ID | DATE | STATE_ON_DATE | YEAR_QUANTITY |
|----|------------|---------------|---------------|
| 1 | 2013-12-30 | 23 | 100 |
| 1 | 2013-12-31 | 25 | 100 |
| 1 | 2014-01-01 | 35 | 150 |
| 1 | 2014-01-02 | 12 | 150 |
| 2 | 2013-12-30 | 34 | 200 |
| 2 | 2013-12-31 | 65 | 200 |
| 2 | 2014-01-01 | 43 | 300 |
Here is SQLFiddle demo It's for SQL Server but should work just fine in MS Accesss.

I'm trying to write an SQL query (SQL Server) that returns the latest value of a field from a history table.
The table structure is basically as below:
ISSUE TABLE:
issueid
10
20
30
CHANGEGROUP TABLE:
changegroupid | issueid | updated |
1 | 10 | 01/01/2020 |
2 | 10 | 02/01/2020 |
3 | 10 | 03/01/2020 |
4 | 20 | 05/01/2020 |
5 | 20 | 06/01/2020 |
6 | 20 | 07/01/2020 |
7 | 30 | 04/01/2020 |
8 | 30 | 05/01/2020 |
9 | 30 | 06/01/2020 |
CHANGEITEM TABLE:
changegroupid | field | newvalue |
1 | ONE | 1 |
1 | TWO | A |
1 | THREE | Z |
2 | ONE | J |
2 | ONE | K |
2 | ONE | L |
3 | THREE | K |
3 | ONE | 2 |
3 | ONE | 1 | <--
4 | ONE | 1A |
5 | ONE | 1B |
6 | ONE | 1C | <--
7 | ONE | 1D |
8 | ONE | 1E |
9 | ONE | 1F | <--
EXPECTED RESULT:
issueid | updated | newvalue
10 | 03/01/2020 | 1
20 | 07/01/2020 | 1C
30 | 06/01/2020 | 1F
So each change to an issue item creates 1 change group record with the date the change was made, which can then contain 1 or more change item records.
Each change item shows the field name that was changed and the new value.
I then need to link those tables together to get each issue, the latest value of the field name called 'ONE', and ideally the date of the latest change.
These tables are from Jira, for those familiar with that table structure.
I've been trying to get this to work for a while now, so far I've got this query:
SELECT issuenum, MIN(created) AS updated FROM
(
SELECT ISSUE.IssueId, UpdGrp.Created as Created, UpdItm.NEWVALUE
FROM ISSUE
JOIN ChangeGroup UpdGrp ON (UpdGrp.IssueID = CR.ID)
JOIN CHANGEITEM UpdItm ON (UpdGrp.ID = UpdItm.groupid)
WHERE UPPER(UpdItm.FIELD) = UPPER('ONE')
) AS dummy
GROUP BY issuenum
ORDER BY issuenum
This returns the first 2 columns I'm looking for but I'm struggling to work out how to return the final column as when I include that in the first line I get an error saying "Column is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause."
I've done a search on here and can't find anything that exactly matches my requirements.
Use window functions:
SELECT i.*
FROM (SELECT i.IssueId, cg.Created as Created, ui.NEWVALUE,
ROW_NUMBER() OVER (PARTITION BY i.IssueId ORDER BY cg.Created DESC) as seqnum
FROM ISSUE i JOIN
ChangeGroup cg
ON cg.IssueID = CR.ID JOIN
CHANGEITEM ci
ON cg.ID = ci.groupid
WHERE UPPER(UpdItm.FIELD) = UPPER('ONE')
) i
WHERE seqnum = 1
ORDER BY issueid;
I'm trying to select some information from a database.
I get a database with columns like:
Ident,Name,Length,Width,Quantity,Planned
Table data is as follow
+-----------+-----------+---------+---------+------------+---------+
| Ident | Name | Length | Width | Quantity | Planned |
+-----------+-----------+---------+---------+------------+---------+
| 12345 | Name1 | 1500 | 1000 | 20 | 5 |
| 23456 | Name1 | 1500 | 1000 | 30 | 13 |
| 34567 | Name1 | 2500 | 1000 | 10 | 2 |
| 45678 | Name1 | 2500 | 1000 | 10 | 4 |
| 56789 | Name1 | 1500 | 1200 | 20 | 3 |
+-----------+-----------+---------+---------+------------+---------+
my desired result, would be to group rows where "Name,Length and Width" are equal, sum the "Quantity" and reduce it by the sum of "Planned"
e.g:
- Name1,1500,1000,32 --- (32 because (20+30)-(5+13))
- Name1,2500,1000,14 --- (14 because (10+10)-(2+4)))
- Name1,1500,1200,17
now I got problems how to group or join these information to get the wished select. may be some you of can help me.. if further information's required, please write it in comment.
You can achieve it by grouping your table and subtract sums of Quantity and Planned.
select
Name
,Length
,Width
,sum(Quantity) - sum(Planned)
from yourTable
group by Name,Length,Width
select
A1.Name,A1.Length,A1.Width,((A1.Quantity + A2.Quantity) -(A1.Planned+A2.Planned))
from `Table` AS A1, `Table` AS A2
where A1.Name = A2.Name and A1.Length = A2.Length and A1.Width = A2.Width
group by (whatever)
So you are comparing these columns form the same table?
I'm attempting to combine multiple rows using a UNION but I need to pull in additional data as well. My thought was to use a UNION in the outer query but I can't seem to make it work. Or am I going about this all wrong?
The data I have is like this:
+------+------+-------+---------+---------+
| ID | Time | Total | Weekday | Weekend |
+------+------+-------+---------+---------+
| 1001 | AM | 5 | 5 | 0 |
| 1001 | AM | 2 | 0 | 2 |
| 1001 | AM | 4 | 1 | 3 |
| 1001 | AM | 5 | 3 | 2 |
| 1001 | PM | 5 | 3 | 2 |
| 1001 | PM | 5 | 5 | 0 |
| 1002 | PM | 4 | 2 | 2 |
| 1002 | PM | 3 | 3 | 0 |
| 1002 | PM | 1 | 0 | 1 |
+------+------+-------+---------+---------+
What I want to see is like this:
+------+---------+------+-------+
| ID | DayType | Time | Tasks |
+------+---------+------+-------+
| 1001 | Weekday | AM | 9 |
| 1001 | Weekend | AM | 7 |
| 1001 | Weekday | PM | 8 |
| 1001 | Weekend | PM | 2 |
| 1002 | Weekday | PM | 5 |
| 1002 | Weekend | PM | 3 |
+------+---------+------+-------+
The closest I've come so far is using UNION statement like the following:
SELECT * FROM
(
SELECT Weekday, 'Weekday' as 'DayType' FROM t1
UNION
SELECT Weekend, 'Weekend' as 'DayType' FROM t1
) AS X
Which results in something like the following:
+---------+---------+
| Weekday | DayType |
+---------+---------+
| 2 | Weekend |
| 0 | Weekday |
| 2 | Weekday |
| 0 | Weekend |
| 10 | Weekday |
+---------+---------+
I don't see any rhyme or reason as to what the numbers are under the 'Weekday' column, I suspect they're being grouped somehow. And of course there are several other columns missing, but since I can't put a large scope in the outer query with this as inner one, I can't figure out how to pull those in. Help is greatly appreciated.
It looks like you want to union all a pair of aggregation queries that use sum() and group by id, time, one for Weekday and one for Weekend:
select Id, DayType = 'Weekend', [time], Tasks=sum(Weekend)
from t
group by id, [time]
union all
select Id, DayType = 'Weekday', [time], Tasks=sum(Weekday)
from t
group by id, [time]
Try with this
select ID, 'Weekday' as DayType, Time, sum(Weekday)
from t1
group by ID, Time
union all
select ID, 'Weekend', Time, sum(Weekend)
from t1
group by ID, Time
order by order by 1, 3, 2
Not tested, but it should do the trick. It may require 2 proc sql steps for the calculation, one for summing and one for the case when statements. If you have extra lines, just use a max statement and group by ID, Time, type_day.
Proc sql; create table want as select ID, Time,
sum(weekday) as weekdayTask,
sum(weekend) as weekendTask,
case when calculated weekdaytask>0 then weekdaytask
when calculated weekendtask>0 then weekendtask else .
end as Task,
case when calculated weekdaytask>0 then "Weekday"
when calculated weekendtask>0 then "Weekend"
end as Day_Type
from have
group by ID, Time
;quit;
Proc sql; create table want2 as select ID, Time, Day_Type, Task
from want
;quit;
This should be a simple one, but say I have a table with data like this:
| ID | Date | Value |
| 1 | 01/01/2013 | 40 |
| 2 | 03/01/2013 | 20 |
| 3 | 10/01/2013 | 30 |
| 4 | 14/02/2013 | 60 |
| 5 | 15/03/2013 | 10 |
| 6 | 27/03/2013 | 70 |
| 7 | 01/04/2013 | 60 |
| 8 | 01/06/2013 | 20 |
What I want is the sum of values per week of the year, showing ALL weeks.. (for use in an excel graph)
What my query gives me, is only the weeks that are actually in the database.
With SQL you cannot return rows that don't exist in some table. To get the effect you want you could create a table called WeeksInYear with only one field WeekNumber that is an Int. Populate the table with all the week numbers. Then JOIN that table to this one.
The query would then look something like the following:
SELECT w.WeekNumber, SUM(m.Value)
FROM MyTable as m
RIGHT OUTER JOIN WeeksInYear AS w
ON DATEPART(wk, m.date) = w.WeekNumber
GROUP BY w.WeekNumber
The missing weeks will not have any data in MyTable and show a 0.
I need to retrieve the records from dbo.transaction (transaction of all users-more than one transaction for each user) that having timestamp which is closest to the time in dbo.bal (current balance details of each user-only one record for each user)
ie, the resultant records should equal to the no of records in the dbo.bal
Here i tried the below query, am getting only the records less than the time in dbo.bal. But there are some record having timestamp greater than and closest to dbo.bal.time
SELECT dbo.bal.uid,
dbo.bal.userId,
dbo.bal.balance,
dbo.bal.time,
(SELECT TOP 1 transactionBal
FROM dbo.transaction
WHERE TIMESTAMP <= dbo.bal.time
ORDER BY TIMESTAMP DESC) AS newBal
FROM dbo.bal
WHERE dbo.bal.time IS NOT NULL
ORDER BY dbo.bal.time DESC
here is my table structure,
dbo.transaction
---------------
| uid| userId | description| timestamp | credit | transactionBal
-------------------------------------------------------------------------
| 1 | 101 | buy credit1| 2012-01-25 03:23:31.624 | 100 | 500
| 2 | 102 | buy credit5| 2012-01-18 03:13:12.657 | 500 | 700
| 3 | 103 | buy credit3| 2012-01-15 02:16:34.667 | 300 | 300
| 4 | 101 | buy credit2| 2012-01-13 05:34:45.637 | 200 | 300
| 5 | 101 | buy credit1| 2012-01-12 07:45:21.457 | 100 | 100
| 6 | 102 | buy credit2| 2012-01-01 08:18:34.677 | 200 | 200
dbo.bal
-------
| uid| userId | balance | time |
-----------------------------------------------------
| 1 | 101 | 500 | 2012-01-13 05:34:45.645 |
| 2 | 102 | 700 | 2012-01-01 08:18:34.685 |
| 3 | 103 | 300 | 2012-01-15 02:16:34.672 |
And the result should be like,
| Id | userId | balance | time | credit | transactionBal
-----------------------------------------------------------------------------
| 1 | 101 | 500 | 2012-01-13 05:34:45.645 | 200 | 300
| 2 | 102 | 700 | 2012-01-01 08:18:34.685 | 200 | 200
| 3 | 103 | 300 | 2012-01-15 02:16:34.672 | 300 | 300
Please help me.. Any help is must appreciated...Thankyou
It would be helpful if you posted your table structures, but ...
I think your inner query needs a join condition. (That is not actually in your question)
Your ORDER BY clause in the inner query could be ABS(TIMESTAMP - DB0.BAL.TIME). That should give you the smallest difference between the 2.
Does that help ?
Based on the follwing Sql Fiddle http://sqlfiddle.com/#!3/7a900/15 I came up with ...
SELECT
bal.uid,
bal.userId,
bal.balance,
bal.time,
trn.timestamp,
trn.description,
datediff(ms, bal.time, trn.timestamp)
FROM
money_balances bal
JOIN money_transaction trn on
trn.userid = bal.userid and
trn.uid =
(
select top 1 uid
from money_transaction trn2
where trn2.userid = trn.userid
order by abs(datediff(ms, bal.time, trn2.timestamp))
)
WHERE
bal.time IS NOT NULL
ORDER BY
bal.time DESC
I cannot vouch for its performance because I know nothing of your data, but I believe it works.
I have simplified my answer - I believe what you need is
SELECT
bal.uid as baluid,
(
select top 1 uid
from money_transaction trn2
where trn2.userid = bal.userid
order by abs(datediff(ms, bal.time, trn2.timestamp))
) as tranuid
FROM
money_balances bal
and from that you can derive all the datasets you need.
for example :
with matched_credits as
(
SELECT
bal.uid as baluid,
(
select top 1 uid
from money_transaction trn2
where trn2.userid = bal.userid
order by abs(datediff(ms, bal.time, trn2.timestamp))
) as tranuid
FROM
money_balances bal
)
select
*
from
matched_credits mc
join money_balances mb on
mb.uid = mc.baluid
join money_transaction trn on
trn.uid = mc.tranuid
Try:
SELECT dbo.bal.uid,
dbo.bal.userId,
dbo.bal.balance,
dbo.bal.time,
(SELECT TOP 1 transactionBal
FROM dbo.transaction
ORDER BY abs(datediff(ms, dbo.bal.time, TIMESTAMP))) AS newBal
FROM dbo.bal
WHERE dbo.bal.time IS NOT NULL
ORDER BY dbo.bal.time DESC
