else
set the parameter date to 1st date of the month.

and then later opretation are being performed on that date into hive quries,
I have wrote this Hive QL

   *select case when as_of_dt = ${hivevar:as_of_dt} then
${hivevar:as_of_dt} else date_sub(${hivevar:as_of_dt} ,
(day(${hivevar:as_of_dt} )) -1 ) end as as_of_dt from TABLE group by
as_of_dt ;*

I want to store the value of this Query int a variable.

like MY_VARIABLE = output of this query;

How to achive that.
