DATA LOAD

ankit777 · ‎2014-03-27

Hi all,

I have a table with two columns. Date and score.

I want to load the data 15 days prior to the max date in my table.

I.e if max date in my table is 28/5/2013 then data should be loaded only till 13/15/2013.

What code should I write in my script?

Hi Ankit,

I don't know by heart, but:

- First try out if you can load the max._value of your date field (using e.g. max(date) or LASTVALUE(date));

- Then construct a WHERE_clause along these lines:

>>> WHERE [date] >= ([max(date)] - 15) <<<

HTH

Best regards,

Hi,

Try :

TMP:

LOAD * FROM table ORDER BY Date desc;

LET vMaxDate = Peek('table', 0, 'Date');

LET vDateMin = Date($(vMaxDate) -15 );

NoConcatenate

DATA:

LOAD *

FROM <table>

WHERE Date >= $(vDateMin)

;

drop table TMP;
