So I have a list with datetimes, mostly there is the same datetimes twice. In the same row of the Dates there is a number which should be summed up and listed in another sheet.
List example (What I Have now):
1 07.09.2015 09:00 118
2 07.09.2015 09:00 31
3 07.09.2015 08:00 148
4 07.09.2015 08:00 56
5 07.09.2015 07:00 128
6 07.09.2015 07:00 49
The List could/should goes like this 24 hours a day 365 times a year, actually its just 3 months at the moment.
And I only want to have one Datetime with one number as sum behind.
It also could be posible that there is the same datetime more than twice
So it should look like this in the desired sheet:
1 07.09.2015 09:00 149
2 07.09.2015 08:00 204
3 07.09.2015 07:00 177
I'm not the best in excel VBA and i only can write a bit of code....
Use a pivot table.
Select all your data. (make sure you have header column and if not add)
select the insert Ribbon and - Insert -> pivot table.
Drag your the date to the rpws and the values as sum the values.
You can refrsh the table each time you add data to the data table by choosing Analyze ribbon -> refresh.
If you want to macro this process , the most simple way for starters is to copy a macro. You can view the code later and improve it.

I have an Access table (Logs) like this:
pk
modID
relID
DateTime
TxType
1
1234
22.3
10/1/22 04:00
1
2
1234
23.1
10/10/22 06:00
1
3
1234
23.1
10/11/22 07:00
2
4
1234
23.1
10/12/22 08:00

4321
22.3
10/2/22 06:00

4321
23.1
10/10/22 06:00

4321
23.1

Trying to write a query as part of a function that searches this table:
for all records matching a given modID and relID (e.g. 1234 and 23.1),
picks the most recent one (the MAX of DateTime),
returns the TxType for that record.
However, a bit new to Access and its query structure is vexing me. I landed on this but because I have to include a Total/Aggregate function for TxType I had to either choose Group By (not what I want) or Last (closer, but returns junk results). The SQL for my query is currently:
SELECT Last(Logs.TxType) AS LastOfTxType, Max(Logs.DateTime) AS MaxOfDateTime
FROM Logs
GROUP BY Logs.dmID, Logs.relID
HAVING (((Logs.dmID)=[EnterdmID]) AND ((Logs.relID)=[EnterrelID]));
It returns the TxType field when I pass it the right parameters, but not the correct record - I would like to be rid of the Last() bit but if I remove it Access complains that I don't have it as part of an aggregate function.
Anyone that can point me in the right direction here?
Have you tried
SELECT TOP 1 TxtType
FROM Logs
WHERE (((Logs.dmID)=[EnterdmID]) AND ((Logs.relID)=[EnterrelID]))
ORDER BY DateTime DESC;
That will give you the latest single data row based on your DateTime field and other criteria.
We currently have a master table stored in our SQL server with the following example information:
Site
Shift Num
Start Time
End Time
Daily Target
A
1
8:00AM
4:00PM
10000
B
1
7:00AM
3:00PM
12000
B
2
4:00PM
2:00AM
7000
C
1
6:00AM
2:00PM
5000
As you can see, there are multiples sites each with their own respective shift start & end times as well as a total daily target for the day.
Another table in the DB is populated by users via the use of a PowerApp. This PowerApp will push output values to the server like so:
Site
Shift Number
Output
Timestamp
A
1
2500
3/15/2022 9:45 AM
A
1
4200
3/15/2022 11:15 AM
A
1
5600
3/15/2022 12:37 PM
A
1
7500
3/15/2022 2:15 PM
This table contains a log of all time-stamped output entries for each site / shift.
What I would like to do is do a daily trend of output vs. target. In order to do so, all output values over a specific shift would have to be aggregated in a SUM function for a given shift grouped by the shift day. The resulting view would need to look like this:
Site
Shift Number
Day
Actual
Target
A
1
3/14
9500
10000
B
1
3/14
13000
12000
A
1
3/15
8000
10000
B
1
3/15
10000
12000
This is easy enough for daytime shifts (group by day and sum the output values). However, if you notice in the master table, Site B / Shift 2 crosses midnight. In this example, I would need to sum values from the previous day 4PM up until 2AM of today. The date grouping would be done by the Shift End Time. Here's an example of the problem area:
Site
Shift Number
Output
Timestamp
B
2
3300
3/15/2022 5:45 PM
B
2
2200
3/15/2022 8:15 PM
B
2
1600
3/16/2022 12:37 AM
B
2
2500
3/16/2022 1:15 AM
I would need these four rows to be aggregated in the view as one row like so:
Site
Shift Number
Day
Actual
Target
B
2
3/16
9600
10000
The values should be listed under March 16th since the end time of the shift occurs then. The values are summated and the target is taken from the daily target master table.
How can I properly calculate these outputs for each shift every day irrespective if it crosses into a new day or not in a view? Or should I go a different route altogether?
I have a table arrivals like this:
HHMM Car
---- ---
0001 01
0001 02
0001 03
0002 04
...
0029 20
0029 21
0030 22
...
0059 56
I need to know how many cars arrived at each range of 30 minutes.
I wrote a query like this:
WITH
PREVIOUS_QUERIES AS
(
-- in fact, "PREVIOUS_QUERIES" represent a sequence of queries where I get
-- the timestamp HHMM and convert it in a range where HOURS = HH and
-- MINUTES_START can be 0 (if MM<30) or 30 (if MM>=30).
),
INTERVALS AS
(
SELECT
TO_CHAR(HOURS,'FM00')||':'||TO_CHAR(MINUTES_START,'FM00')||' - '
||TO_CHAR(HOURS,'FM00')||':'||TO_CHAR(MINUTES_START +29,'FM00') AS INTERVAL,
CAR
FROM
PREVIOUS_QUERIES
)
SELECT
INTERVAL,
COUNT (DISTINCT (CAR)),
FROM INTERVALS
GROUP BY INTERVAL
ORDER BY INTERVAL
;
My query produces the following results.
Interval Cars
------------- ----
00:00 - 00:29 21
00:30 - 00:59 35
01:00 - 01:29 41
02:30 - 02:59 5
03:00 - 03:29 12
03:30 - 03:59 13
...
That means, if there are no arrivals in some interval, my query doesn´t show a line with Cars=0. I need these rows in my results:
01:30 - 01:59 0
02:00 - 02:29 0
How could I add these rows? Can it be done with a change on my query, or
should this query be completely rewritten?
What I imagine is that I should generate the 48 ranges of 30 minutes from '00:00-00:29' to '23:30-23:59' and then use them as a parameter for SELECT, but I don´t know how to do it.
You could just select those 48 values into another CTE, something like 'cteIntervals', and then adjust the final query to be something like:
SELECT
I.Interval
, NVL(Q.Cars, 0) Cars
FROM
cteIntervals I
LEFT JOIN
(
-- Your current query
) Q
ON I.Interval = Q.Interval
This has the effect of creating a template for the final query to fit into.
For a slightly more dynamic solution you could look into producing cteIntervals using a recursive CTE, or you could store the values in a table, etc.
I have built a dynamic crosstab query where the user selects options from multiple combo boxes and then I use VBA to update the SQL for the cross tab query. It is then, in turn, displayed on a subform. My question is basically how can I programmatically (VBA or SQL, don't really care either way) add a totals row that calculates the average of each column. I know how to do this manually, but since the number of columns and column headings are not set, this is impractical. I would basically like to automatically set a totals row at the bottom for the average of each column regardless of the number of columns or column headers. An example of a potential case is shown below with the user inputs on top.
Group: A
Team: All
Start Date: 1/1/2014
End Date: 5/31/2014
Query Type: Monthly

John Doe1 1 2 3 4 5
John Doe2 2 2 2 2 2

John Doe9 1 12 23 34 45
Total (Avg): 1.44 8.89 16.33 23.78 31.22
I am trying the generate the bottom "Totals" row programmatically without knowing the column count ahead of time and without manually inserting totals via the ribbon.
You can use a pivot table on a simple select query.
Doesn't the crosstab query do that for you?
https://support.office.com/en-us/article/Make-summary-data-easier-to-read-by-using-a-crosstab-query-8465B89C-2FF2-4CC8-BA60-2CD8484667E8
http://www.fmsinc.com/microsoftAccess/query/crosstab-report/index.html
Although crosstab queries are somewhat limited in their power, you can certainly create another query to do a basic average of the crosstab query you just created.
Please note: this is not for an Access project as such, but a legacy application that uses an Access database for its back end.
Setup
Part of the application is a kind of Gantt chart, fixed to single day columns, where each row represents a single resource. Resources are booked out for a range of days and a booking is for a single resource, so they cannot overlap on a row. The range of dates that is in view is user selectable, open ended, and can be changed by various methods, including horizontal scrolling using mouse or keyboard.
Problem
I've been tasked with adding a row to the top of the chart to indicate overall resource usage for each day. Of course that's trivially easy to do by simply querying for each day in the range separately, but unfortunately that is proving to be an expensive process and therefore slows down horizontal scrolling a lot. So I'm looking for a way to do it more efficiently, hopefully with fewer database reads.
Here is a highly simplified example of the bookings table:
booking_ID | start_Date | end_Date | resource_ID
----------- -------------- ------------- -------------
1 2014-07-17 2014-07-20 21
2 2014-08-24 2014-08-29 4
3 2014-08-26 2014-09-02 21
4 2014-08-28 2014-09-04 19
Ideally, I would like a single query that returns each day within the specified range, along with a count of how many bookings there are on those days. So querying the data above for 20 days from 2014-07-17 would produce this:
check_Date | resources_Used
----------- ---------------
2014-07-17 1
2014-07-18 1
2014-07-19 1
2014-07-20 1
2014-07-21 0
2014-07-22 0
2014-07-23 0
2014-08-24 1
2014-08-25 1
2014-08-26 2
2014-08-27 2
2014-08-28 3
2014-08-29 3
2014-08-30 2
2014-08-31 2
2014-09-01 2
2014-09-02 2
2014-09-03 1
2014-09-04 1
2014-09-05 0
I can get a list of dates in the range by using a table of integers (starting at 0), with this:
SELECT CDATE('2014-07-17') + ID AS check_Date FROM Integers WHERE ID < 20
And I can get the count of resources used for a single day with something like this:
SELECT COUNT(*) AS resources_Used
FROM booking
WHERE start_Date <= CDATE('2014-09-04')
AND end_Date >= CDATE('2014-09-04')
But I can't figure out how (or if) I can tie them both together to get the desired results. Is this even possible?
Create a table called "calendar" and put a list of dates into it covering the necessary timeframe. It just needs one column called check_date with one row for each date. Use Excel, start at whatever date and just drag down, then import into the new table.
After your calendar table is set up you can run the following:
select c.check_date, count(b.resource_id) as resources_used
from calendar c, bookings b
where c.check_date between b.start_date and b.end_date
group by c.check_date
