Change column format from General to Date

Hi Experts, 

 

I have a column in my data set that Qlik has recognized as General, however I want to convert it to Date. 

 

The column is in MMM/DD/YYYY hh:mm:tt (e.g. Apr 4 2008 4:00AM) and I want to convert it to DD/MMM/YYYY format. Have tried a few variations of the screenshot attached but to no avail. Any ideas where I'm going wrong? Should I be converting it in the load script?

Best way to handle this problem is to change the format of the field at database end itself to have a unique format for all the values. If it is not possible then you need to identify all the unique format exists in all the field values and use the alt function to change format for each

Let's assume you identified below two formats in your data

'MMM D YYYY hh:mmTT' ,'DD.MM.YYYY hh:mmTT'

then you can below logic in qlik to convert

date(floor(alt(timestamp#(Date,'MMM D YYYY hh:mmTT'),timestamp#(Date,'DD.MM.YYYY hh:mmTT'))),'DD/MMM/YYYY') as Date

Hi @Kushal_Chawda 

Just for the record a solution was eventually arrived at. Hopefully the below formula may help anyone in the future 🙂 

 

Date(makedate(num(If(num(subfield("datefield",' ',3))<10, subfield("datefield",' ',4), subfield("datefield",' ',3))), sum(month(date#(subfield("datefield",' ',1),'MMM'))), num(If(subfield("datefield",' ',2)='', subfield("datefield",' ',3),subfield("datefield",' ',2)))) ,'DD MMM YYYY') as NewDateField

Hi,
Try this:
Date(Date,'DD/MMM/YYYY') as Upd_date

Thanks,
Usama

Maybe like this

Date(Date#('Mar 25 2008 4:00AM','MMM DD YYYY hh:mmtt'),'MMM/DD/YYYY')

try below

=date(floor(timestamp#(Date,'MMM D YYYY hh:mmTT')),'DD/MMM/YYYY')

Thanks everyone for their replies, 

@Kushal_Chawda  was the closest to getting it. I inserted your formula into the load script but it seems to now only return one date?! 

Very unusual error if anyone could point me in the right direction I would really appreciate it !

@qliky88 

Assuming you have put down the formula in load script correctly. If so I don't think any chances of getting error. It might be that all time field values don't have same format due to which only few are getting converted

LOAD *,

          date(floor(timestamp#(YourTimeField,'MMM D YYYY hh:mmTT')),'DD/MMM/YYYY') as Date

FROM table;

@qliky88  Can you check that CAPA_CLOSE_DATE coming from source has same format for all values ?
