Hi.

Try with:

ABC:

LOAD

Date(Max(Date#(Left(Date, 10), 'DD/MM/YYYY'))) as Date

INLINE [

Date

31/08/2018 12:00:00 AM

30/09/2018 12:00:00 AM

];

LET sDATE = Peek('Date', 0 , 'ABC');

And use the variable in the where condition.

Where Date#(Left(Date, 10), 'DD/MM/YYYY') = sDate

Saludos

try this


=MAX(NUM(DATE(FLOOR(Timestamp#(DATE)),'DD/MM/YYYY')))


or


=MAX(NUM(DATE(FLOOR(Timestamp#(trim(DATE))),'DD/MM/YYYY')))

Hi,

first of all, i think you are reading "DATE" field from a database and don't be fooled by the format because that field is not a timestamp. if you make the field as a numeric you'll see only integer values.

and try this for getting your max value:

[Table of facts]:

load *

from X;

Temp:

Load

num(max(Date)) as DataMax

Resident [Table of facts];

drop table [Table of facts];

LET vDataMax = Peek('DataMax',-1,'Temp');

hope it helps,

Andrei
