Please can you someone help me?
My question is :
How to use properly OR in IIF
statement in RDLC report?
Both Fields!A.Value and Fields!B.Value contains string or empty string.
This code works fine:
=Iif(Len(CStr(First(Fields!A.Value, "dsResult_dtRows")))=0, True, False)
This code doesnt work:
=Iif(Len(CStr(First(Fields!A.Value, "dsResult_dtRows")))=0 Or
Len(CStr(First(Fields!B.Value, "dsResult_dtRows")))=0, True, False)
thanks a lot for ideas and answers

you should be able to concatenate the field values and test for the empty string instead of testing each value individually.
try
IIF(Fields!A.Value & Fields!B.Value = '',true,false)
for either empty returning true, try:
IIF(Fields!A.Value ='' or Fields!B.Value = '',true,false)

I keep getting a returned "Error:" with my code but have no idea why when the same code works fine with a similar dataset.
Changed the observation variable, changed the time restrictions, searched for similar problems online
library(rerddap)
CalPoly = info("HABs-CalPoly", url= "http://erddap.sccoos.org/erddap/")
CalPoly_Data = tabledap(CalPoly,
fields = c('Ceratium','Cochlodinium', 'Dinophysis_spp', 'Gymnodinium_spp','time'),
'time>=2008-08-15T00:00:00Z', 'time<=2019-05-26T05:35:00Z')
Should return a data table but I just keep getting "Error:"
This similar code does work though and I have no idea why
CalCOFI = info('siocalcofiHydroCasts')
calcofi.df <- tabledap(CalCOFI,
fields = c('cst_cnt', 'date', 'year', 'month', 'julian_date', 'julian_day', 'rpt_line', 'rpt_sta', 'cruz_num', 'intchl', 'intc14', 'time'),
'time>=1984-01-01T00:00:00Z', 'time<=2014-04-17T05:35:00Z')
Resolved the issue!
I initially set the url correctly for the info argument, I didn't realize I had to set the url again for the tabledap argument. I did not realized it the Default is: https://upwell.pfeg.noaa.gov/ erddap/
Five hours later but at least it is resolved!
The code now works:
CalPoly_Data = tabledap(CalPoly, fields = c('Temp','time'),'time>=2008-08-15T07:00:00Z', 'time<=2019-05-26T07:00:00Z', url = "http://erddap.sccoos.org/erddap/")
I have a select input with multiple options and my Mongo query
Here is the array if elements:
c<- c("elen","shallen")
query1 <- paste0('{"client": {"$in"["',c,'"]}')
#sales info is the data base
salesinfo$find(fields = '{"store":true,"_id":false}',query = query1)
Error: Invalid JSON object: {"client": [ elen ]}{"client": [ shallen ]}
this isn't working please help me please remember that it is a dynamic array and the values will change
After extensive research i found a way to solve the issue and i hope my solution will help out guys like me.
q1=paste(shQuote(c, type="cmd"), collapse=", ")
this step is to ensure you print out the array as a string and then use the query
query =paste0('{"store":{"$in":[',q1,']}}')
and the next step would be incorporating it to the query
salesinfo$find(fields = '{"store":true,"_id":false}',query = query)
Hei guys! I need help in a python program. I wanna make a method which returns the sum of the keys as a dictionary. But I get a error "object is not iterable".
def totaltAntallSalg (dic) :
s = sum (dic.keys)
return s
call_function = totaltAntallSalg({"Ahmed":2,"Nada":1, "hala":3 })
How can I solve this problem?
thanks in advance
How can you add strings ? It might be values that you want to add.
To add values you may use following code:-
def totaltAntallSalg(dic):
D={}
D['sum']=sum(dic.values())
return D
I want to delete the part of string existing after "|". For Example String s = HelloWorld|ABCD i want to delete ABCD.
I want to do it in asp.net. Help Will be much appreciated.
subString method might be used for this but i dont know how to do it.
Kindly help me out with this.
int pipeIndex = s.IndexOf("|");
s = pipeIndex == - 1 ? s : s.Substring(0, pipeIndex);
This is the most efficient way, maybe you find this more readable:
s = s.Split('|')[0];
I try to group by my customize movieLense dataset
groupBy<- data.table(unifiedTbl)
x<- groupBy[,list(rating=sum(rating)
,Unknown=sum(unknown)
,Action=sum(Action)
,Adventure = sum(Adventure)
,Animation = sum(Animation)
,"Children's" = sum(Children's)
),by=list(user_id,age,occupation)]
but because of Children's I received some error which related to specified character
If I remove below part of my code every things is OK
,"Children's" = sum(Children's)
Now my question is how can I address to this column with full name?
how can I fix my codes?
You can use backticks with names that aren't valid syntax:
`Children's` = sum(`Children's`)
And of course, I'd recommend creating valid names instead:
setnames(groupBy, make.names(names(groupBy)))
