I run a query every day to place in a file. It is regarding effective date and term dates of coverage. occasionally have a group that will actually term and become effective again the next day. I need help with SQL code that will pick up the original effective date and the latest expiration date. The example that I am giving is a very small part of the table.. due to hippa regulations. The SQL code that I currently am using is super easy query code and I have supplied just the lines of data within the attachment.you will see where this member has 2 effect dates and 2 term dates I need to display it as one..with 01/01/2018 as effect and 12/31/9999 as term. cannot figure out how to add an attachment.. so I am just going to copy the two rows.
meme_altid meme_eff meme_trm
S409666X1E 2018-01-01 2018-12-31
S409666X1E 2019-01-01 9999-12-31
Earliest eff and latest term?
Select meme_altid, Min(meme_eff) As eff, Max(meme_trm) As term From #tbl

Timestamp is a string in 'YYYY-MM-DD' format.
I want to make a chart and a pivot table in Google DataStudio that automatically filters by the latest datapoints ('2022-02-15' in the example). All the solutions I tried are either sub-optimal or just don't work:
Creating a support column doesn't work because I need to mix aggregated and non-aggregated fields (data_date and the latest data_date)
Adding a filter to the charts allows me to specify only a specific day - I would need to edit the chart regularly every time the underlyind data is updated
Using a dropdown filter allows me to dynamically filter whatever date I need. However I consider it suboptimal because I can't have it automatically select the latest date. Having a date filter can make it dynamic, but since the update time is not regular it may select a date range with multiple timestamps/or none at all, so it's also a sub-optimal solution
Honestly I'm out of ideas. I stupidly thought it was possible to add a column saying data_date = (select max(data_date) from dataset, but it seems not possible since max needs to work on aggregated data.
One possible solution could be creating a view that can have the latest data point, and referencing the view from the data studio.
CREATE OR REPLACE VIEW `project_id.dataset_id.table_name` AS
SELECT *
FROM `bigquery-public-data.covid19_ecdc_eu.covid_19_geographic_distribution_worldwide`
ORDER BY date DESC # or timestamp DESC
LIMIT 1
50 records in databank. I prepared a query to select contracts with ending dates between 1/1/2019 and 12/31/2020. Some of the records have dates outside the 12/31/2020; 12/31/2021. I want those records included as they were active during the queried period.
The between query only returns records with the ending date of 12/31/2020. I changed the criteria to end period between 1/1/2019 and 12/31/2021 and not 12/31/2022. That returns records before end end date of 12/31/20 and outside the start of the end period of 1/1/2019.
I've tried about 10 other things (can't remember all of them) regardless am not getting the results I need.
I'm not VBA/SQL friendly, I'm a query kind of user. Sorry if that makes my question a little more difficult.
Thank you soooo much for any direction you can give me!!
select *, DATE_FORMAT(*datetime_column*,'%m/%d/%Y') from *table_name* where *datetime_column* between '1/1/2019' and '12/31/2020'
I think the format of date leads to 'query don't satisfy correct result' problem. You could convert the date to this format and check the result
I would like to make an SQL-Statement in order to find the amount of users that are using a channel by date and time. Let me give you an example:
Let's call this table Data:
Date Start End
01.01.2020 17:00 17:30
01.01.2020 17:01 17:03
01.01.2020 17:29 18:30
Data is a table that shows when an user started the connection on a channel and the time the connection was closed. A connection can be made any time, which means from 00:00 until the next day.
What I am trying to achieve is to count the maximum number of connections that were made over a big period if time. Let's say 1st February to 1st April.
My idea was to make another table with timestamps in Excel. The table would display a Timestamp for every Minute in a specific date.
Then I tried to make a statement like:
SELECT *
FROM Data,Timestamps
WHERE Timestamps.Time BETWEEN Data.Start AND Data.End.
Now logically this statement does what is supposed to do. The only problem is that it is not really performant and therefore not finishing. With the amount of timestamps and the amount of data I have to check it is not able to finish.
Could anybody help me with this problem? Any other ideas I can try or how to improve my statement?
Regards!
So why dou you create another table in Excel and not directly in MS Access and then why won't you set up the indexes of the timestamps right. That will speed it up by factors.
By the way I think that your statement will print repeat every user that happened to match your Start .. End period, so the amount of rows produced will be enormous. You shall rather try
SELECT Timestamps.Time, COUNT(*)
FROM Data,Timestamps
WHERE Timestamps.Time BETWEEN Data.Start AND Data.End
GROUP BY Timestamps.Time;
But sorry if the syntax in MS Access is different.
I've got a bit of a weird logic problem that I can't seem to wrap my head around (perhaps from studying it for too long).
Where I work we have a very old piece of software that we're required to use to track the status of equipment that we use. This software provides very little functionality to manipulate these statuses to try and provide a good analysis of downtime. I've been working on a database application in Access (since it's the only tool they make available to me) to import status data from the old system into a format that is more easily manipulated.
The way status data is spit out from the old program is fairly straight-forward:
EQUIPNAME STATUS STARTDATETIME ENDDATETIME
It's easy enough to read that text and insert it into the table in Access. The problem I'm having comes from trying to find how many hours a piece of equipment spent in different statuses over different date ranges.
The start/end date/time can be any length of time. Finding which rows contain the dates is difficult. I've been using BETWEEN statements in SQL to try and find them which, for the most part, works out well:
SELECT * FROM Statuses WHERE
(StartDateTime BETWEEN [StartDT] AND [EndDT])
OR
(EndDateTime BETWEEN [StartDT] AND [EndDT])
The real issue is when StartDateTime is BEFORE StartDT and EndDateTime is AFTER EndDT (ie the entire range I'm looking for is INSIDE this status's start/end dates). It simply doesn't find it, which makes sense.
I can't seem to come up with an elegant solution to this. I need to be able to select all rows which contain a status that contains or is contained within the supplied date range. I wouldn't normally come here for such a simple problem, but my brain and Google-fu are failing me.
A little bit of sample data:
EQUIP STATUS STARTDATETIME ENDDATETIME
A123 OPER 01/30/2013 21:30 12/31/1999 00:00
A123 DFM 01/26/2013 10:42 01/30/2013 21:29
A123 OPER 01/01/2013 00:00 01/26/2013 10:41
B123 OPER 01/01/2013 00:00 12/31/1999 00:00
C123 DFU 01/29/2013 12:31 12/31/1999 00:00
C123 OPER 01/01/2013 00:00 01/29/2013 12:30
Any kind of booking collusion occurs when:
RequestStartDate <= EndDate
and
RequestEndDate >= StartDate
The above will ALSO return overlaps. So if I query today + tomorrow, and a range starts at the being of the year to the end of the year, the query WILL be included in the range.
Eg:
Select * from tblEQUIP
where
#01/31/2013# <= ENDDATETIME
and
#02/01/2013# >= StartDateTime
At that point you can "process" each record. You likely have to use something like:
Do while RecordDate.eof = false
For datePtr = RequestStartDateTime to RequestendDateTime
If datePtr >= RecordData!StartDateTime and DatePtr <= RecordData!EndDateTime then
DaysTotal = DaysTotal + 1
End if
Next DatePtr
recordData.Movenext
loop
The above is air code, but shows the basic processing loop you need to first grab the overlapping records, and then a processing loop to add up days/time for each record in your date range that does fall withing the given date range.
Interesting question ! Sorry not to have much time now to eleborate, but I would advise to explore the Partition function for that, or and/or doing a crosstab query with the date as column heading. More on msoffice site and here.
Suppose ,I have a table which has all the billing records. Now I want to see the sales trend for a user given time duration group by each 3 days ...what should be the sql query regarding this?
please help,Otherwise I am gone ...
I can only give a vague suggestion as per the question, however you may want to have a derived column with a standardised date (as per MS date format, just a number per day) that you could then use a modulus (3) on so that days are equal per 3 day period. You can then group and aggregate over this column to get the values for a 3 day period. Obviously to display the date nicely you would have to multiply back and convert your column as well.
Again I'm not sure of the specifics, but I think this general idea could be achieved to get a result (may well not be the best way so it would help to add more to the question...)
