I am trying to duplicate a detail object from Desktop to its Webi equivalent.
I am familiar with the syntax differences, i.e. using semicolons instead of commas and using [] rather than <> to enclose references to other dimensions/measures/detail objects.
Given the working formula from the Deski report:
=ToDate(7+"/1/"+<Current FY>-1 ,"mm/dd/yyyy")
I tried to convert this using the syntax I know from Webi:
=ToDate(7+"/1/"+[Current FY]-1 ; "mm/dd/yyyy")
I faced the error message
The expression or sub-expression at position 8 in the '-' function uses an invalid data type
I am guessing this has something to do with trying to convert a date datatype into an integer in order to subtract "1." However, I do not know what kind of function this requires.
Thanks in advance!

I was trying to query the duration of a WWE wrestler in the matches which he won and here I have successfully retrieved the data:
I would like to remove those zeros and I tried the following piece of code:
strftime(%H:%M:%S, R1.time_in_match)
which doesn't work and give the following error:
': near "%": syntax error
The data I imported were from a data frame which stores the time as time object and put them into the database as type DATETIME. The typeof function used on the "time_in_match" field returned type TEXT.
I was wondering if there is any way to format the time.
Thanks!
SQLite provides 2 functions for this case:
strftime('%H:%M:%S', R1.time_in_match)
and simpler:
time(R1.time_in_match)
because:
The time() function returns the time as HH:MM:SS
(from Date And Time Functions)
See the demo.
Your expression works as intended if you surround the format specifier with single quotes:
strftime('%H:%M:%S', time_in_match)
You could also just use string functions here:
substr(time_in_match, 1, 8)

I have tried everything that I can think of to get the right date format. Can anybody help with this RPA-problem in UiPath. I have used the 'get text' activity to get the folder date and after that tried to use the
Datetime.ParseExact(Str variable,"dd/MM/yyyy", System.Globalization.CultureInfo.InvariantCulture).
It gives me the error:
Assign: String was not recognized as a valid DateTime.
Your help is much appreciated.
edit: I have now sought help from a friend who figured it out. The error was in the string, which could not be seen, because there was an invisible character in the string that I extracted through 'get text' activity. The solution is in 2 steps:
assign another variable to the exact same date and use an if statement to find out if these two strings are equal and you will find out that they are not.
Now use a regex to capture only digits and slash/hyphen which will get rid of the invisible character.
Try to use "dd_MM_yyyy" instead of "dd/MM/yyyy".
The reason is because UiPath/VB.Net has a habit of using US date formatting even though you're using Culture Info...It's a real pain
Try this:
pDateString = "21/02/2020"
Assign a Date type variable = Date.ParseExact(pDateString,"dd/MM/yyyy",nothing)
Here we're telling the parser to use English format date...The Date type returned will be in US format but you can simply convert back to uk IF needed by using something like:
pDateString("dd/MM/yyyy")
I have a column called "Bakery Activity" whose values are all JSONs that look like this:
{"flavors": [
{"d4js95-1cc5-4asn-asb48-1a781aa83": "chocolate"},
{"dc45n-jnsa9i-83ysg-81d4d7fae": "peanutButter"}],
"degreesToCook": 375,
"ingredients": {
"d4js95-1cc5-4asn-asb48-1a781aa83": [
"1nemw49-b9s88e-4750-bty0-bei8smr1eb",
"98h9nd8-3mo3-baef-2fe682n48d29"]
},
"numOfPiesBaked": 1,
"numberOfSlicesCreated": 6
}
I'm trying to extract the number of pies baked with a regex function in Tableau. Specifically, this one:
REGEXP_EXTRACT([Bakery Activity], '"numOfPiesBaked":"?([^\n,}]*)')
However, when I try to throw this calculated field into my text table, I get an error saying:
ERROR: function regexp_matches(jsonb, unknown) does not exist;
Error while executing the query
Worth noting is that my data source is PostgreSQL, which Tableau regex functions support; not all of my entries have numOfPiesBaked in them; when I run this in a simulator I get the correct extraction (actually, I get "numOfPiesBaked": 1" but removing the field name is a problem for another time).
What might be causing this error?
In short: Wrong data type, wrong function, wrong approach.
REGEXP_EXTRACT is obviously an abstraction layer of your client (Tableau), which is translated to regexp_matches() for Postgres. But that function expects text input. Since there is no assignment cast for jsonb -> text (for good reasons) you have to add an explicit cast to make it work, like:
SELECT regexp_matches("Bakery Activity"::text, '"numOfPiesBaked":"?([^\n,}]*)')
(The second argument can be an untyped string literal, Postgres function type resolution can defer the suitable data type text.)
Modern versions of Postgres also have regexp_match() returning a single row (unlike regexp_matches), which would seem like the better translation.
But regular expressions are the wrong approach to begin with.
Use the simple json/jsonb operator ->>:
SELECT "Bakery Activity"->>'numOfPiesBaked';
Returns '1' in your example.
If you know the value to be a valid integer, you can cast it right away:
SELECT ("Bakery Activity"->>'numOfPiesBaked')::int;
I found an easier way to handle JSONB data in Tableau.
Firstly, make a calculated field from the JSONB field and convert the field to a string by using str([FIELD_name]) command.
Then, on the calculated field, make another calculated field and use function:
REGEXP_EXTRACT([String_Field_Name], '"Key_to_be_extracted":"?([^\n,}]*)')
The required key-value pair will form the second caluculated field.
I'm trying to build a bank file using SSRS report builder (3.0). I'm running into two issues:
I'm trying to get a length expression to work on a check number field but LEN(Field) doesn't work (returns 4 as the value regardless of the actual length of the field).
And LENGTH(Field) gives me an error:
The Value expression for the textrun 'Textbox15.Paragraphs[0]. TextRuns[0\' contains an error: [BC30451] Name 'LENGTH' is not declared*
The only reason why I'm even trying to get #1 to work is because I need to have one of the fields on the bank file have a constant length. Regardless of the check number, I need to make sure this field is always at 14 characters with leading zeros. I thought the best way to do this is to do a switch statement and add the number of appropriate zeros in depending on the size of the check number field.
Thanks for the help.
Edit: using a SQL server DB
For the length issue:
There are two ways to get string length
Using the LEN function
= LEN(Fields!myfield.Value)
Using the length property
= Fields!myfield.Value.Length
If your field is not a string, try converting first by using the Cstr function
= LEN( Cstr(Fields!myfield.Value) )
= Cstr(Fields!myfield.Value).Length
For the formatting issue:
For numeric fields set the cell format expression to have as many zeros as required eg. for 14 digit numbers
= "00000000000000"
I don't know on which database you are working if you are using sql server then try LEN
function and LENGHT in oracle.
I think you first convert it into integer if it's character and then try len function.
I have two datasets in my report and data is being displayed through a table. When I give expression like below:
=Format(Fields!InvDt.Value, "dsRepSalesReport_tblPrintSalesReport","dd/MMMyyyy")
It says there is Syntax error. If I remove dsRepSalesReport_tblPrintSalesReport part, there is no error.
1) Please advise how to wite the expression in format with aggregate expression.
2) If I write expression without dsRepSalesReport_tblPrintSalesReport part, my table repeats data and shows for all invoice. But when I add aggregate part, dsRepSalesReport_tblPrintSalesReport
Table just shows one value several times.
Please advise how to handel with these two issues.
Thanks
The method signature for Format is:
Public Shared Function Format(
ByVal Expression As Object,
Optional ByVal Style As String = ""
) As String
So that means you can't just specify the field and the Scope as in your first example; the first of the two arguments must return one value only.
In your example, you could use something like:
=Format(First(Fields!InvDt.Value, "dsRepSalesReport_tblPrintSalesReport"), "dd/MMMyyyy")
Which will format the first value in the specified Scope.
Another option would be to just set the value as required in the report then use the Format property:
It's difficult to answer your second question without knowing what your data/required results are... If you update the question with some simplified sample data to illustrate the actual issue you're facing that would be helpful.
