I'm trying to figure out a DateAdd() equivalent in Oracle that is actually the difference in seconds between 2 columns in the same table:
SELECT
DISTINCT p.packet_id,
p.launch_dt,
r.route_duration,
s.completion_date,
DATEADD(SS, r.route_duration, p.launch_dt) AS tempDate
FROM
tdc_arc_apprpkt_def p
JOIN tdc_arc_inpr_route_def r
ON p.packet_id = r.packet_id
JOIN tdc_arc_inpr_route_step_detai s
ON p.packet_id = s.packet_id
AND s.completion_date > DATEADD(SS, r.route_duration, p.launch_dt)
Any help would be greatly appreciated!
In addition to being able to do date arithmetic using fractions of days as Tony demonstrates, assuming you are using 9i or later, you can also use interval functions (or, even better, define the ROUTE_DURATION column as an interval) and add intervals to dates. In your case, you can do
p.launch_dt + numtodsinterval( r.route_duration, 'SECOND' )
to add route_duration seconds to launch_dt.
If you were to define the route_duration column as an INTERVAL DAY TO SECOND rather than a NUMBER, you could simply add it to a date
p.launch_dt + r.route_duration
If I understand you correctly, you want to add r.route_duration seconds to p.launch_dt? In that case the expression is:
p.launch_dt + (r.route_duration/24/60/60)
Oracle DATE arithmetic works in days, so the divisions by 24, 60 and 60 convert the route_duration value from seconds to days.

In my cube, I have several measures at the day grain that I'd like to sum at the day grain but average (or take latest) at the month grain or year grain.
Example:
We have a Fact table with Date and number of active subscribers in that day (aka PMC). This is snapshotted per day.
dt
SubscriberCnt
1/1/22
50
1/2/22
55
This works great at the day level. At the month level, we don't want to sum these two values (count = 105) because it doesn't make sense and not accurate.
when someone is looking at month grain, it should look like this - take the latest for the month. (we may change this to do an average instead, management is still deciding)
option 1 - Take latest
Month-Dt
Subscribers
Jan-2022
55
Feb-2022
-
option 2 - Take aveage
Month-Dt
Subscribers
Jan-2022
52
Feb-2022
-
I've not been able to find the right search terms for this but this seems like a common problem.
I added some sample data at the end of a month for testing:
dt
SubscriberCnt
12/30/21
46
12/31/21
48
This formula uses LASTNONBLANKVALUE, which sorts by the first column and provides the latest value that is not blank:
Monthly Subscriber Count = LASTNONBLANKVALUE( 'Table'[dt], SUM('Table'[SubscriberCnt]) )
If you do an AVERAGE, a simple AVERAGE formula will work. If you want an average just for the current month, then try this:
Current Subscriber Count =
VAR _EOM = CLOSINGBALANCEMONTH( SUM('Table'[SubscriberCnt]), DateDim[Date] )
RETURN IF(_EOM <> 0, _EOM, AVERAGE('Table'[SubscriberCnt]) )
But the total row will be misleading, so I would add this so the total row is the latest number:
Current Subscriber Count =
VAR _EOM = CLOSINGBALANCEMONTH( SUM('Table'[SubscriberCnt]), DateDim[Date] ) //Get the number on the last day of the month
VAR _TOT = NOT HASONEVALUE(DateDim[MonthNo]) // Check if this is a total row (more than one month value)
RETURN IF(_TOT, [Monthly Subscriber Count], // For total rows, use the latest nonblank value
IF(_EOM <> 0, _EOM, AVERAGE('Table'[SubscriberCnt]) ) // For month rows, use final day if available, else use the average
)
I want to calculate total value between two dates in DAX. I have a formula SUM(C5:C16) in excel sheet, which C5 is the sales amount for a specific date (last year + 1month), and C16 is the sales amount for current row date.
I tried this formula in DAX, but it did not return sum value:
var Rolling = CALCULATE(sum('proces'[HOURS]),DATESINPERIOD('Date'[DateField],ENDOFMONTH('proces'[date_start]),-12,MONTH))
Also, I tried this one, but it is not working:
=SumX (
var prev=DATEADD(DATEADD('proces'[date_start] ,-1,YEAR),+1,MONTH)
return
Filter ( 'proces',
'proces'[date_end] <= Earlier ( 'proces'[date_end] ) &&
'proces'[date_start]>=prev,
'proces'[HOURS])
Also, I tried this one but it returns nothing
=CALCULATE(
SUMX('proces','proces'[HOURS]),
DATESBETWEEN(
'Date'[DateField],
STARTOFMONTH(DATEADD(LASTDATE('Date'[DateField]),-1,MONTH)),
ENDOFMONTH(DATEADD('Date'[DateField],-1,MONTH))
)
)
You seem to be confused about variables in DAX and your formulas are not even valid DAX expressions. Learn about variables in the official documentation:
Use variables to improve your DAX formulas
If you need further help with calculating the your total amount, add sample data to your question.
I have a table that is being joined like so
result: select from table where date within (sd;ed)
where sd and ed span multiple months (like sd:2021.07.01 ed:2021.09.30). The table that I'm querying from has a break if you take more than a month, so to get the result I need, I have to do something like the following:
result: uj(uj(select from table where date within (2021.07.01;2021.07.30);select from table where date within (2021.08.01;2021.08.31));select from table where date within (2021.09.01;2021.09.30))
How can I make this dynamic for any sd and ed? That is, how can I break up time range into first days of months, last days of months, and join them all into one table cleanly? My initial idea was to divide the days in the range x amount of time, to be input by a user, then add the number of days that results to the sd to get frames, but that got messy.
Something like this should chunk it for you:
raze{select from t where date within x}each(first;last)#\:/:d group"m"$d:sd+til 1+ed-sd
Do not use where date.month=x as you had suggested - at least not for historical queries
One option for converting your start and end dates into an iterable list of dates might be:
f:{0N 2#(x,raze -1 0+/:`date$mx+1+til(`month$y)-mx:`month$x),y}
Where x is start date and y is end date.
f[2021.07.14;2022.02.09]
2021.07.14 2021.07.31
2021.08.01 2021.08.31
2021.09.01 2021.09.30
2021.10.01 2021.10.31
2021.11.01 2021.11.30
2021.12.01 2021.12.31
2022.01.01 2022.01.31
2022.02.01 2022.02.09
Then you could run:
{select from t where date within x} each f[sd;ed]
And join the results using raze or (uj/)
I am new to Talend I want to find the difference between the two timestamps.
I am having two columns start_time and end_time.
I want to make a table in destination that will show the difference in both the timestamps, specifically I want to show hours mins and seconds.
Also I want time in timestamp not in ling format, how can I achieve this
start_time- 2021-06-18 08:27:52.000000
end_time- 2021-06-18 08:29:59.000000
I tried-
creating a variable 'ms' of long type in tmap = TalendDate.diffDate(row181.start_time,row181.end_time,"mm")
for converting into hh:mm:ss
String.format("%02d:%02d:%02d.%d", (Var.ms / (1000 * 60 * 60)) % 24, (Var.ms / (1000 * 60)) % 60, (Var.ms / 1000) % 60, Var.ms % 1000)
if I make table as string I am getting this err-
column "call_duration" is of type bigint but expression is of type character varying
Above T-map expression returning zero also I have to use long in the destination column type, but I want date type
Pattern "MM" refers to months, not minutes. Use "mm" instead.
How could you return a date type for a difference between two dates ? The result is necessarily a number (long/double...) .
If you want your output with hours/mins/seconds, you should use diffDate with "ss" pattern to get a long representing the duration in seconds. Then you'll have to transform this to get hours and minutes (e.g 3700 s would give you 1 hour, 1 minute, 40 seconds) . You also have to determine what kind of output you want (one column for each, a string with the concatenation of hours/minutes/seconds...)
Example : with row1.diffDate being your diffdate in seconds in input of a tMap, you could separate in three different columns. Then you'll only have to concatenate all values in a string. if you want a string output with ":" separator.
Team,
I'm trying to get the last 12 months of financials, using the days as my base, and am getting the the expression yield error. I think it's because they aren't text, but calculated columns.
What is best to add to this? I tried 'value' and that didn't work. I think the isnonblank may work.. or is blank? As there will be blanks returned.
Here's the formula:
Last 12 Mn Amt = (if('LSI DP_JP_HistorySummaryBySiteMaster'[Z - Days]>=-365,'LSI DP_JP_HistorySummaryBySiteMaster'[Z Total Revenue + Rent Revenue],""))
The problem is that the TRUE result returns a different data type than the FALSE result.
Try replacing "" with blank or zero.
Last 12 Mn Amt =
IF (
'LSI DP_JP_HistorySummaryBySiteMaster'[Z - Days] >= -365,
'LSI DP_JP_HistorySummaryBySiteMaster'[Z Total Revenue + Rent Revenue],
BLANK ()
)
Note: Omitting the 3rd argument entirely returns BLANK() as the default behavior.
