I want to create a sheet trigger to select the previous year and the current year but not the current month.
If for example we were in 201604...
Sample data is as follows:
201511
201512
201601
201602
201603
201604
Selection I would want would be:
201511
201512
201601
201602
201603
In the Trigger expression you can use the YearStart function along with the MAX function to get all of the previous year plus the current years months excluding the current month.
='<' & Max(YearMonth) & '>=' & Num#(Date(YearStart(Max(Date#(YearMonth, 'YYYYMM')), -1), 'YYYYMM'), '##')

The below gives me week numbers where week 1 starts on 1/4/2021
date_trunc('week', transaction_date) as week_number
How can I create a week_number where the week starts on January 1st and counts up 7 days for every week thereafter (for every year)?
And round up/down to 52 weeks at the end of the year?
Code attempted:
This doesn't give me the answer, but I'm thinking something like this might work...
ceil(extract(day from transaction_date)/7) as week_number
Expected Output:
transaction_date
week_number
1/1/2020
1
1/8/2020
2
...
...
12/31/2020
52
1/1/2021
1
1/8/2021
2
...
...
12/27/2021
52
12/28/2021
52
12/29/2021
52
12/30/2021
52
12/31/2021
52
1/1/2022

Thanks in advance!
A simple way is to use date arithmetic:
select 1 + (transaction_date - date_trunc('year', transaction_date)) / 7 as year_week
The below gives me week numbers where week 1 starts on 1/4/2021
It is the default behaviour and it is defined that way in ISO.
WEEK_OF_YEAR_POLICY
Type Session — Can be set for Account » User » Session
Description
Specifies how the weeks in a given year are computed.
Values
0: The semantics used are equivalent to the ISO semantics, in which a week belongs to a given year if at least 4 days of that week are in that year.
1: January 1 is included in the first week of the year and December 31 is included in the last week of the year.
Default 0 (i.e. ISO-like behavior)
It could be overrriden on multiple levels. The most granular is on the session level:
ALTER SESSION SET WEEK_OF_YEAR_POLICY = 1;
Then you could use the standard code:
SELECT date_trunc('week', transaction_date) as week_number
FROM ...;
I have date field and from that date field i am trying to extract only weekends i.e. in my case Saturday and Sunday is weekend.
So how can i extract weekends from date?
If below dates are in weekend then should be like this:
Date day working hours
01/01/2019
02/01/2019
03/01/2019
04/01/2019
05/01/2019 weekend 24
06/01/2019 weekend 87
07/01/2019
08/01/2019
09/01/2019
10/01/2019

You can use WeekDay functon. This function accepts date value/field and return the day of the week. The returned value is in dual format - day name and day number.
So you can create additional field that checks if the day number is >= 5 (day numbers are starting from 0 so Saturday = 5 and Sunday = 6)
RawData:
LOAD
AttendanceDay,
if(WeekDay(AttendanceDay) >= 5, 1, 0) as isWeekend,
Employee_ID,
WorkingHours
FROM
[..\Downloads\ar.xlsx]
(ooxml, embedded labels, table is Attendances_20191119_0838)
;
Resulted table after the reload:
I have a table with the month, identifier and revenue for that month. What I would like to do is create a new field that for every row is the average revenue of the previous three months i.e. 'Prev_3month_Average'. Does anyone know a good sql function for this rather than joining the table onto itself three times?
E.g
Month ID Revenue Prev_3month_Average
201601 123 5 null
201602 123 10 null
201603 123 8 null
201604 123 10 7.666666667
201605 123 5 9.333333333
Thanks in advance!
I would like a column displaying the fiscal week. Our fiscal year begins in April.
So far I have the below, using datename(ww,DateAndTime) as Week
DateAndTime Week
2015-04-01 22:45 14
2015-06-14 13:22 25
2015-12-02 09:15 49
2016-01-01 07:35 1
I would like the output to show:
DateAndTime Week Fiscal Week
2015-04-01 22:45 14 1
2015-06-14 13:22 25 12
2015-12-02 09:15 49 36
2016-01-01 07:35 1 41
While I don't understand the logic behind the fiscal week (the difference between 1 and 41 is 40, but between 14 and 1 it's 39), maybe I'm missing something or you made a typo.
However, in general you'd do something like this (assuming the difference is 40 weeks):
SELECT week, (week+40)%52 AS fw FROM ...
If the fiscal year starts at a different week every each (say, 13th or 14th week depending on year), you can use the date and time functions, but they may vary between SQL versions. In MySQL you have YEAR(), MONTH(), WEEK(), etc.
For example:
SELECT week, (week+(52-WEEK(CONCAT_WS('-', YEAR(NOW()), '04-01'))))%52 FROM ...
But it might be overkill.
Note: It is possible to count the other way: if you subtract the diff from the week instead of adding, you will need to add 52 if the number is negative. You can do that by adding 52 and then doing modulo (%) 52.
There is this one table which contains the amounts and states that I need. However, this table contains a year information but I want month. For example, in the table it shows information for Kentucky for 2011..and thats it. For California it shows about 5 different years. But I need it to repeat by month.
So if in 2011 Kentucky had 12 total, then I need a query that shows 12 for January, February, May....repeatedly
Right now I get this output with a dumb query I have:
Kentucky 12 January
California 800 January
This is done easily by grouping by State, Quantity and Month
I want to make sure that no matter what the Quantity is, each State has ALL months
Kentucky 12 January
Kentucky 12 February
Kentucky 12 May
California 800 January
California 800 February
California 800 May
Any idea on how to do this with Teradata SQL?
The overall query would look something like this:
SELECT
state_quantities.state,
state_quantities.quantity,
all_months.month_name
FROM state_quantities
CROSS JOIN (
...
) all_months
What goes between the brackets for all_months depends on what you mean by "all months".
If you mean all months that appear in state_quantities irrespective of state (so if you have Kentucky with January, California with February and Florida with May, you'd only get those three months) you could use something like this:
SELECT
month_name
FROM state_quantities
GROUP BY month_name
If you want all 12 months, you would join to a table containing all 12 months. In the absence of that, you could use sys_calendar.calendar (syntax below might be off):
SELECT
CAST(calendar_date AS DATE FORMAT 'MMM') AS month_name
FROM sys_calendar.calendar
GROUP BY month_name
