I have tried Num((today()-I_TRAN_DATE)/90 + 1,0) individually and it will return integer, but it seems not working when I try to combined it with pick function. I know it's not finished but should at least return result for 1-3
pick(
Num((today()-I_TRAN_DATE)/90 + 1,0)
,'less than 3 months'
,'3-6 months'
,'6-12 months'
,'greater than 1 year'
)
This looks like an issue with passing the number from the expression to the pick function. When using the num function, this does not change the underlying value - including a few more brackets and a round function resolves the issue as per the below script which generates a list of dates and then applies the pick function at the end.
Let varMinDate = Num(31350); //30/10/1985
Let varMaxDate = Num(42400); //31/01/2016

We're currently rebuilding basic emailed reports built using T-SQL to be paginated reports published on Power BI.
We're muddling through by creating the tables we need with the appropriate filters in Power BI Desktop to reconcile the numbers, then taking the DAX code from them using the Performance Analyser.
The one I'm working at the minute has a simple bit of SQL code to get data for a previous calendar month. I have no idea how or if it's possible for this to exist in DAX?
-- Validation to get previous month
IF (MONTH(GETDATE()) - 1) > 0
SET #MONTH = MONTH(GETDATE()) - 1
ELSE
SET #MONTH = '12'
-- Validation to get year of previous month
IF (#MONTH < 12)
SET #YEAR = YEAR(GETDATE())
ELSE
SET #YEAR = YEAR(GETDATE()) - 1
-- Set start date and finish date for extract
SET #PERIOD = #YEAR + RIGHT('00' + #MONTH, 2)
It needs to become a hidden SSRS parameter or just inline code to be used with this DAX variable:
VAR __DS0FilterTable =
TREATAS({"202212"}, 'Org View_VaultexCalendar'[Calendar Month No])
So the "202212" would become #period or the equivalent if doable without a parameter.
SSRS Parameter:
=IIF(
Month(Today()) > 1,
Year(Today()) & RIGHT("00" & Month(Today()) - 1, 2),
Year(Today())-1 & "12"
)
DAX expression:
IF (
MONTH ( TODAY () ) > 1,
YEAR ( TODAY () ) & FORMAT ( MONTH ( TODAY () ) - 1, "00" ),
YEAR ( TODAY () ) - 1 & "12"
)
In both cases we look at today's month and check if it's after January. If it is, take the current year and concatenate it with the current month less one and padded with a leading zero when needed. In the other case we know that the month is January so take the current year less one and concatenate it with "12"
i need to calculate difference between two date excluding sunday. I have table with dates and i need to calculate number of dates of repeated days from last date.
if i have dates like that
27-05-2017
29-05-2017
30-05-2017
I use this code in script
date(max(Date)) as dateMax,
date(min(Date)) as dateMin
And i get min date = 27-05-2017 and max date = 30-05-2017 then i use in expressions
=floor(((dateMax - dateMin)+1)/7)*6 + mod((dateMax - dateMin)+1,7)
+ if(Weekday(dateMin) + mod((dateMax - dateMin)+1,7) < 7, 0, -1)
And get result 3 days. Thats OK, but the problem is if I have next dates:
10-05-2017
11-05-2017
27-05-2017
29-05-2017
30-05-2017
When use previously code I get min date = 10-05-2017 and max date = 30-05-2017 and result 18, but this is not OK.
I need to count only dates from
27-05-2017
29-05-2017
30-05-2017
I need to get max date and go throw loop repeated dates and if have brake to see is that date sunday if yes then step that date and continue to count repeated dates and if i again have break and if not sunday than close loop and remember number of days.
In my case instead of 18 days i need to get 3 days.
Any idea?
I'd recommend you creating a master calendar in the script where you can apply weights or any other rule to your days. Then in your table or app you can just loop through the dates or perform operations and sum their weights (0: if sunday, 1: if not). Let's see an example:
// In this case I'll do a master calendar of the present year
LET vMinDate = Num(MakeDate(year(today()),1,1));
LET vMaxDate = Num(MakeDate(year(today()),12,31));
Calendar_tmp:
LOAD
$(vMinDate) + Iterno() - 1 as Num,
Date($(vMinDate) + Iterno() - 1) as Date_tmp
AUTOGENERATE 1 WHILE $(vMinDate) + Iterno() - 1 <= $(vMaxDate);
Master_Calendar:
LOAD
Date_tmp AS Date,
Week(Date_tmp) as Week,
Year(Date_tmp) as Year,
Capitalize(Month(Date_tmp)) as Month,
Day(Date_tmp) as Day,
WeekDay(Date_tmp) as WeekDay,
if(WeekDay = '7',0,1) as DayWeight //HERE IS WHERE YOU COULD DEFINE A VARIABLE TO DIRECTLY COUNT THE DAY IF IT IS NOT SUNDAY
'T' & ceil(num(Month(Date_tmp))/3) as Quarter,
'T' & ceil(num(Month(Date_tmp))/3) & '-' & right(year(Date_tmp),2) as QuarterYear,
date(monthStart(Date_tmp),'MMMM-YYYY') as MonthYear,
date(monthstart(Date_tmp),'MMM-YY') as MonthYear2
RESIDENT Calendar_tmp
ORDER BY Date_tmp ASC;
DROP Table Calendar_tmp;
How to find out Number of Workdays(Monday to Friday) between two dates in SAP HANA ? We do not have to consider holidays.
We cant use WORKDAYS_BETWEEN() as we do not have TFACS table.
Here is how you can so ist in sql:
Calculate the number of whole weeks, multiply by 5
Add the remaining days: subtract weekday start date from weekday end date, correct for weekends (least...), Correct for carry-over (+5)
The second part can be simplified a little so that you don't have to write the subtraction twice.
Here an example with start date '2015-12-04' and end date '2015-12-19):
SELECT ROUND( DAYS_BETWEEN (TO_DATE ('2015-12-04', 'YYYY-MM-DD'), TO_DATE('2015-12-19', 'YYYY-MM-DD')) / 7, 0, ROUND_DOWN) * 5
+ ( case
when WEEKDAY (TO_DATE('2015-12-19', 'YYYY-MM-DD') ) - WEEKDAY (TO_DATE('2015-12-04', 'YYYY-MM-DD')) >= 0
then least( WEEKDAY (TO_DATE('2015-12-19', 'YYYY-MM-DD')), 5) - least( WEEKDAY (TO_DATE('2015-12-04', 'YYYY-MM-DD')), 5)
else
least( WEEKDAY (TO_DATE('2015-12-19', 'YYYY-MM-DD')), 5) - least( WEEKDAY (TO_DATE('2015-12-04', 'YYYY-MM-DD')), 5) + 5
end )
"Workdays" FROM DUMMY;
--> 11
I preferred to create a user defined function here to use in HANA SQLScript codes as follows
Create Function CalculateWorkDays (startdate date, enddate date)
returns cnt integer
LANGUAGE SQLSCRIPT AS
begin
declare i int;
cnt := 0;
i := 0;
while :i <= days_between(:startdate, :enddate)
do
if WEEKDAY( ADD_DAYS(:startdate,:i) ) < 5
then
cnt := :cnt + 1;
end if;
i := :i + 1;
end while;
end;
Please note that the above code block seems to contain an unnecessary loop.
On the other hand, if you have additional tables like department holidays, or personal holidays, etc. It might be useful to check these tables in the WHILE loop. Please refer to following SQL tutorial Calculate the Count of Working Days Between Two Dates where I created a similar SQL function checking custom work calendars or holiday calendars.
Here is how you call the function as sample
select CalculateWorkDays('20170101', '20170131') as i from dummy;
I hope it helps,
I'm trying to convert some MS Access queries to T-SQL to use in SSIS (basically converting Access db to SQL server 2008) and I'm having trouble converting an IIF() statement. I tried several approaches and it always resulted in an error.
The query creates a column with dates that are "original Date + 2 years if the condition is met and original Date + 1 if the condition is not met". The first part of the IIF() eliminates the case of the original year being a leap year and so the possibility of generating a non-existing date.
The original IIF() statement is:
IIf((Day(Date)=29 And Month(Date)=2),
IIf(Desc Like "*" & "123" & "*",
DateSerial(Year(Date)+2,Month(Date),Day(Date)-1),
DateSerial(Year(Date)+1,Month(Date),Day(Date)-1)),
IIf(Desc Like "*" & "123" & "*",
DateSerial(Year(Date)+2,Month(Date),Day(Date)),
DateSerial(Year(Date)+1,Month(Date),Day(Date)))) AS Term
So the problem is not only an IIF() statement but also DATESERIAL function. I found the solution for the DATESERIAL() function using CAST() (SQL server 2008 does not have the DATEFROMPARTS() function...).
I tried using CASE() like this:
CASE
WHEN DAY(Date)=29 AND Month(Date)=2 THEN
CASE
WHEN Desc LIKE "%123%" THEN
CAST(CAST(YEAR(Date)+2 AS VARCHAR(4)) + RIGHT('0' + CAST(MONTH(Date) AS VARCHAR(2)), 2) + RIGHT('0' + CAST(DAY(Date)-1 AS VARCHAR(2)), 2) AS DATETIME )
ELSE CAST(CAST(YEAR(Date)+1 AS VARCHAR(4)) + RIGHT('0' + CAST(MONTH(Date) AS VARCHAR(2)), 2) + RIGHT('0' + CAST(DAY(Date)-1 AS VARCHAR(2)), 2) AS DATETIME ) END
ELSE CASE
WHEN Desc LIKE "%123%" THEN
THEN CAST(CAST(YEAR(Date)+2 AS VARCHAR(4)) + RIGHT('0' + CAST(MONTH(Date) AS VARCHAR(2)), 2) + RIGHT('0' + CAST(DAY(Date) AS VARCHAR(2)), 2) AS DATETIME )
ELSE CAST(CAST(YEAR(Date)+1 AS VARCHAR(4)) + RIGHT('0' + CAST(MONTH(Date) AS VARCHAR(2)), 2) + RIGHT('0' + CAST(DAY(Date) AS VARCHAR(2)), 2) AS DATETIME )END END AS Term
I also tried using COAELSCE() but with no better outcome.
I really don't know if I have made some kind of syntax error or where the problem could be.
Thank you in advance for any help.
edit: I'll add error message I'm getting: Incorrect syntax near '...'. The '...' changes as I try different approaches, sometimes its ELSE, THEN etc.
SQL Server's DATEADD may help to simplify things here...
CASE WHEN (<your condition>)
THEN DATEADD(YEAR, 1, [OriginalDate])
ELSE DATEADD(YEAR, 2, [OriginalDate])
END
Should also cope with leap years too.
DateSerial is such a useful function to have around, just create your own.
I got my version from here:
CREATE FUNCTION dbo.DateSerial
(
#year int,
#month int,
#day int
)
RETURNS datetime
AS
BEGIN
DECLARE #date datetime
-- convert date by adding together like yyyymmdd
SET #date = cast(#year * 10000 + 101 AS char(8));
-- Add to date the proper months subtracting 1, since we used 1 as start instead of zero.
SET #date = dateadd(mm , #month - 1 , #date)
-- Add to date the proper days subtracting 1, since we used 1 as start instead of zero.
SET #date = dateadd(dd , #day - 1 , #date);
RETURN #date ;
END;
GO
Here is another way: Date serial in SQL?
Then use the function just as you did in Access.
Edit: just noticed that your outer IIF is to handle leap years. This is not needed when using dateadd().
I get to dust off my VBScript hat and write some classic ASP to query a SQL Server 2000 database.
Here's the scenario:
I have two datetime fields called fieldA and fieldB.
fieldB will never have a year value that's greater than the year of fieldA
It is possible the that two fields will have the same year.
What I want is all records where fieldA >= fieldB, independent of the year. Just pretend that each field is just a month & day.
How can I get this? My knowledge of T-SQL date/time functions is spotty at best.
You may want to use the built in time functions such as DAY and MONTH. e.g.
SELECT * from table where
MONTH(fieldA) > MONTH(fieldB) OR(
MONTH(fieldA) = MONTH(fieldB) AND DAY(fieldA) >= DAY(fieldB))
Selecting all rows where either the fieldA's month is greater or the months are the same and fieldA's day is greater.
select *
from t
where datepart(month,t.fieldA) >= datepart(month,t.fieldB)
or (datepart(month,t.fieldA) = datepart(month,t.fieldB)
and datepart(day,t.fieldA) >= datepart(day,t.fieldB))
If you care about hours, minutes, seconds, you'll need to extend this to cover the cases, although it may be faster to cast to a suitable string, remove the year and compare.
select *
from t
where substring(convert(varchar,t.fieldA,21),5,20)
>= substring(convert(varchar,t.fieldB,21),5,20)
SELECT *
FROM SOME_TABLE
WHERE MONTH(fieldA) > MONTH(fieldB)
OR ( MONTH(fieldA) = MONTH(fieldB) AND DAY(fieldA) >= DAY(fieldB) )
I would approach this from a Julian date perspective, convert each field into the Julian date (number of days after the first of year), then compare those values.
This may or may not produce desired results with respect to leap years.
If you were worried about hours, minutes, seconds, etc., you could adjust the DateDiff functions to calculate the number of hours (or minutes or seconds) since the beginning of the year.
SELECT *
FROM SOME_Table
WHERE DateDiff(d, '1/01/' + Cast(DatePart(yy, fieldA) AS VarChar(5)), fieldA) >=
DateDiff(d, '1/01/' + Cast(DatePart(yy, fieldB) AS VarChar(5)), fieldB)
Temp table for testing
Create table #t (calDate date)
Declare #curDate date = '2010-01-01'
while #curDate < '2021-01-01'
begin
insert into #t values (#curDate)
Set #curDate = dateadd(dd,1,#curDate)
end
Example of any date greater than or equal to today
Declare #testDate date = getdate()
SELECT *
FROM #t
WHERE datediff(dd,dateadd(yy,1900 - year(#testDate),#testDate),dateadd(yy,1900 - year(calDate),calDate)) >= 0
One more example with any day less than today
Declare #testDate date = getdate()
SELECT *
FROM #t
WHERE datediff(dd,dateadd(yy,1900 - year(#testDate),#testDate),dateadd(yy,1900 - year(calDate),calDate)) < 0
