problem in automating Hive table extraction due to date-parameter difficulty

Hi All,

I have a transformation which picks data from Hive table and load it to the mysql database.

The query extracting Hive's database is "select * from hive_table where days=20130903" which is in yyyyMMdd format.

I need to execute the same transformation on daily basis. as I need to automate this what would be the parameter for days column which increases by 1 on daily basis.

I dont know how to provide the date parameter to the same query in table input step.

Please provide your inputs. It will be great help.
Thanks in advance.
