load expression in script

[#1]

hello

i've a problem. In my board i have two fields, booth are date/time field like 01-01-2012 08:00 fits date/time is the startdate and the other the finishdate.

In some tables i used the expression finishdate - startdate to calculate the duration, no problem with that.

But nw i want this expression to be loaded in the script, so that a new field ak duration ia avalable. When this new field is avalable i can make a statistic object

, which displays the maximum/mimimus/averige duration.

Anyone suggestions

Okay so to solve this you need to use the timestamp function as well as the interval function:

Since I don't have your actual data I made an inline table.

The script:

test:

LOAD * INLINE [

CUSTOMERNBR, ARTNBR, YEAR, SALES, DATETIME1, DATETIME2

5436698, 3154, 2011, 317000, 01-01-2012 08:00, 01-01-2012 02:00

5436698, 3154, 2010, 325000, 01-02-2011 07:00, 01-01-2011 07:00

5436698, 3169, 2011, 100000, 03-01-2010 02:00, 02-01-2010 02:00

5436698, 3169, 2010, 150000, 02-01-2013 10:00, 01-01-2013 10:00

]

;

test2:

LOAD *,

timestamp#(DATETIME1,'MM-DD-YYYY hh:mm') as DATETIME_A,

timestamp#(DATETIME2,'MM-DD-YYYY hh:mm') as DATETIME_B,

'' as Junk

Resident test;

drop table test;

test3:

LOAD *,

DATETIME_A - DATETIME_B as Duration,

' ' as Junk2

Resident test2;

drop table test2;

test4:

LOAD *,

interval(Duration, 'MM-DD-YYYY hh.mm') as Difference,

' ' as Junk3

Resident test3;

Drop table test3;

I am subtracting DATETIME1-DATETIME2 for your results.

You can also change the format of the difference by changing the MM-DD-YYYY hh.mm part.

I also attached a QV file let me know if you need any other help.

Hope this helps!
