In my cloud flow, I need to check each of the date columns and update "ActiveDate" with the column name that is within 7 days of today's date.
So for the sample below I'd hope to populate ActiveDate with the value "Date1"
{
"RPTID": "RPT4072",
"Date1": "2021-07-02",
"Date2": "2021-09-17",
"Date3": "2021-10-22",
"Date4": "2022-02-25",
"Date5": "2022-05-20",
"Date6": "2023-03-07",
"ActiveDate": "",
"ProjectManager": "TBC",
"QuantitySurveyor": "Mr A / Mr B"
}
I feel like I'm going round in circles trying to figure out how to do this. I've tried IF syntax and also the Condition action but can't seem to get the correct logic. Any help is much appreciated.
Below is the source and SELECT from excel.
I have then added a loop and tried to update the date calculation with a variety of options and none have worked.
The screenshot above throws this error:
InvalidTemplate. Unable to process template language expressions in action 'Compose_2' inputs at line '1' and column '43252': 'In function 'formatDateTime', the value provided for date time string 'Date3' was not valid. The datetime string must match ISO 8601 format.'.
Here are a couple errors that let me on to trying the integer pointer above:
'The template language expression 'div(sub(ticks(formatDateTime(body('Select')[item()], 'yyyy-MM-dd')),ticks(formatDateTime(substring(utcNow(),0,10),'yyyy-MM-dd'))),864000000000)' cannot be evaluated because property 'Date1' cannot be selected. Array elements can only be selected using an integer index.

Array elements can only be selected using an integer index.

I feel like it needs some sort of item().value but for the life of me I can't get it..
The tricky part is to calculate the date difference for each date and then update the property in your json object.
Date Difference Calculation
div(sub(ticks(formatDateTime(variables('Result')[item()], 'yyyy-MM-dd')),ticks(formatDateTime(substring(utcNow(),0,10),'yyyy-MM-dd'))),864000000000)
Update Property in Json object
setProperty(variables('result'), 'ActiveDate', variables('FinalDate'))
Let's assume that you have your json object in a variable. I am initialising a variable Result for that. Apart from this you need one variable FinalDate for storing the desired date and another variable Dates for storing your 6 date keys.
Now you need to loop over all date keys and find the date difference for each date and check if it falls in the range -7 <= Dif <= 7. If yes assign the FinalDate object to that particular date. Check the image below.
Now you just need to update you original json object. You ca simply use setProperty method to do so as depicted below.

Is is possible in a Table to Calculate differences between Dates if the Value in the field is considered "short text"?
I am working to convert an Excel macro database into Access one and I have imported the data from the Excel file into an Access Table.
however i realized 2 feilds that count up until closure are now just fixed numbers but need to add up as each day passes until closure
when i imported the Dates became Short Text.
is there an expression that would handle this situation?
Each record has a serialized non repeating ID number seperate from access as well.
Dates I have are
OfficialissuanceDate,
DatePlanSubmitted,
DatePlanCompletedSubmitted,
DateClosed,
I need 2 calculations that increments daily when DateplanSubmitted and DatePlanCompletedSubmitted are null
Both comparing to OfficialIssuanceDate. then stop counting when they are no longer null. (have a date in updated to the record) and retain the value.
I have tried to Google calculating Dates but i get DateDiff function which doesnt appear to work. I've used Access and taken a class on it but never really made a new DB from scratch
Dates in a text field are not actual dates, just strings of characters. A Date/Time field stores value as a double number then displays in a date structure - "dd/mm/yyyy" is Access default structure.
Sometimes Access will do implicit conversion of data but not in this case. Either change field type to Date/Time or do conversion with CDate() function. However, you will find that conversion functions error with Null input.
Arithmetic operation with Date/Time field type is possible. However, arithmetic when any term is null returns Null so have to deal with that. One way uses Nz() function: Nz([DateClosed], Date()) - [DateOpened]. Unfortunately, Nz() is not available in table Calculated field type, so do that calc in query or textbox. Most developers avoid table Calculated field type. If you really want to use, expression would have to be: IIf(IsNull([DateClosed), Date(), [DateClosed]) - [DateOpened].
Background:
Trying to achieve a filter in dataset, if the user selects Day shift from the parameter, any data entry between 06:00:00 and 18:00:00 is filter in the report. Furthermore, any data entry between 18:00:00 and 06:00:00 is reflect in the report for Night shift
Process:
I have got a parameter with 2 Boolean values "True" and "False". I have labeled those values as "Day shift" and "Night shift" in the available value Parameter window option. Default value is true.
Converting datetime to time, in the dataset query
SELECT
CONVERT(time, SWITCHOFFSET(CONVERT(datetimeoffset, LastModified),DATENAME(TzOffset, SYSDATETIMEOFFSET()))) as ShiftTime
FROM table abc
Filter expression:=Fields!ShiftTime.Value
Operator: in
Value: =IIf( ( TimeValue(Fields!ShiftTime.Value) >= "06:00:00" And TimeValue(Fields!ShiftTime.Value) <= "18:00:00" ) , Parameters!ShiftType.Value(0), Parameters!ShiftType.Value(1) )
Problem: [BC30516] Overload resolution failed because no accessible
'IIf' accepts this number of arguments
Not sure which part I am going wrong with, I am thinking it is the datatype but unsure.
Solution which I built on
I'm not sure what report designer you are using, but using the Report Designer extension for Visual Studio gives me very different errors.
And it gives errors both in the output window, and the expression window when building it.
Firstly to debug this, add it as a column to your report before you try and implement it as a filter.
Then check the relevant documentation for the function. It turns out the TimeValue function takes a string, not a DateTime, and returns a datetime.
Then, you can't access the available parameter values from the parameter, you can only access the selected parameter values. So instead of Parameters!ShiftType.Value(0) (which has a red line under it) you should just have true (or false depending on which way around your logic is) i.e. the value of the parameter.
Finally, I don't know what implicit conversion SSRS does from strings to a time, so I would do an explicit time compare instead of a string compare. Given we know that TimeValue returns a DateTime with the minimum date value and the time component we can compute the required limites for day/night shift.
The following is what worked for me:
=IIf(TimeValue(Fields!ShiftTime.Value.ToString()) >= DateTime.MinValue.AddHours(6) And TimeValue(Fields!ShiftTime.Value.ToString()) <= DateTime.MinValue.AddHours(18), true, false)
And actually re-visiting it, thats way too convoluted, you are already returning a time value which we can compare directly as
=IIf(Fields!ShiftTime.Value >= new TimeSpan(6,0,0) And Fields!ShiftTime.Value <= new TimeSpan(18,0,0), true, false)
And then your filter should be:
Filter expression: {as shown above}
Operator: =
Value: =Parameters!ShiftType.Value
Note: when you say "between" I don't know whether the intention is to include both 6am and 6pm within the day shift window, but I haven't modified your logic in that regard.
I cannot work out why these Total expressions don't work...
I am trying to add any cells that have a date later than today, with any cells that have "Not Reqd", and then divide that by the number of rows, to get a percentage.
All I'm getting is #Error.
These are the expressions I've tried:
=SUM(IIf(Fields!Jetter_Trng.Value >Today OR
Fields!Jetter_Trng.Value = "Not Reqd",1,0)))/(Count(Fields!Jetter_Trng.Value)
and
=Count(IIf(Fields!Jetter_Trng.Value >Today OR
Fields!Jetter_Trng.Value = "Not Reqd",1,Nothing)))/(Count(Fields!Jetter_Trng.Value)
The "Not Reqd" string has come from an expression that changes a date (01/01/1950) to "Not Reqd". Maybe this is messing things up:
=iif(Fields!Jetter_Trng.Value = "01/01/1950", "Not Reqd", Fields!Jetter_Trng.Value)
The current working expression (not looking for "Not Reqd") is:
=COUNT(IIF(Fields!Jetter_Trng.Value>Today,1,Nothing)))/(Count(Fields!Name.Value))
I'm a bit lost...
A couple of notes on your expression as it stands at present
Jetter_Trng appears to be a string representing either a date or “Not Reqd”. You can’t compare strings to dates without casting them to a date type first using CDATE()
The number of braces (( and )) do not match
The root of your problem though is that you are using Jetter_Trng to return either a Date, or the value “Not Reqd”.
When SSRS attempts to evaluate an expression it does it all at the same time. It doesn’t follow a path to find the answer, and ignore other paths. Therefore, when you are attempting to compare
Fields!Jetter_Trng.Value >Today
This is comparing a string to a date, and throwing the error, as this mean nothing
"Not Reqd" > Today
You won’t be able to do all that you want to using only one Field of type string.
Your options are to
Use two fields – the date and a flag indicating not required, or
Use one field – but have an “invalid date” (01/01/2100 perhaps) that you could then treat as the “Not Reqd” value, and check if the current date is less than that (which it always will be)
Using the second option here you could then use the following expression to create the desired calculation
=sum(iif(CDate(Fields!Jetter_Trng.Value) > Today, 1, 0)) /
Count(Fields!Jetter_Trng.Value)
Which would evaluate this dataset as follows
I have added a Filter in Row Group-> Group Properties to perform sum of quantity only for those transactions which have done before a certain date.
Whenever I am selecting the 'Cdate' as Expression field from my dataset1, the type is showing as Date/Time but after saving it when I check,I found it as 'Text'. As a result the filter for 'cDate' is not working during report generation.
Note that, I can't filter the data in dataset side or tablix side as I have to show all the column items. This is a matrix report.
OK this is going to be a bit confusing because your dataset contains a field with the same name as one of the built-in expression functions ("CDate" - Convert to Date).
I sometimes run into these datatype issues when using filters and I find the best way to handle it is to force both the filter field and the filter value to be the same data type.
So in your case try setting the Filter expression to:
=CDate(Fields!CDate.Value)
then select the operator as "<=" and set the value using an expression as well:
=CDate(Parameters!MyParameter.value)
and see if that works.
I understand you so that your date field in the dataset is called CDate, try casting it as date, so instead of selecting it in your filter, type the following into the filter
=CDate(Fields!CDate.Value)
The matrix's odd rows contain strings, representing integer numbers. The even rows contain strings, representing dates in mm/dd/yyyy format. The order is not guaranteed, it could be the other way around if someone changed the category names.
The grand total row has to be added to this matrix, but the following expressions throw an #Error:
=Sum(Iif(IsDate(Fields!Data.Value), 0, CInt(Fields!Data.Value)))
=Sum(Iif(InStr(Fields!Data.Value, "/"), 0, CInt(Fields!Data.Value)))
Converting 0 and field value to some other numeric data types did not work too.
Interesting enough, the expressions partially work for the grand total column, i.e. they calculate the numbers' row total, but #Error on the dates rows.
Protecting the row grand total as follows did not help either:
=Iif(Fields!Results.Value = "# of items", CStr(Sum(CInt(Fields!Data.Value))), "")
What is the correct way to implement data driven conditional totals?
I could do this in plain SQL and dump into a tablix in a heartbeat but this has to be wrapped in SSRS and used with an existing matrix which must not be changed otherwise.
The #ERROR you get on the date rows is due to the CInt conversion failing.
This is because IIF is a function, not a language construct so both the true and false parameters get evaluated before being passed to the function regardless of the value of the boolean condition parameter. This means that:
=Sum(Iif(IsDate(Fields!Data.Value), 0, CInt(Fields!Data.Value)))
will always attempt the conversion to integer regardless of the result of the IsDate function.
Try using Val instead of CInt. The problem with CInt is it errors when the string to be converted is an inappropriate form; Val doesn't have that problem - it simply grabs whatever numbers it can. So you can use the expression:
=Sum(Iif(IsDate(Fields!Data.Value), 0, Val(Fields!Data.Value)))
and then simply format it like an integer.
Note that the Val function is still being run even when the field is not numeric but this expression succeeds because the Val function doesn't raise errors like Cint. We simply make the calculation and discard the result when the field is a date.
This expression, combining the tips from both answers with additional protection, works:
=Iif(
IsNumeric(Fields!Data.Value),
Sum(Val(Iif(InStr(Fields!Data.Value, "/"), "", Fields!Data.Value))),
0
)
