First Date of the Given date and month

Hi Evryone,

I want to extract first day of the given date.

For Ex: i aam giving date "30-jan-2013" but i want to show "01-jan-2013".

In Oracle, Trunc function behaving mentioned above. So i need appropriote function in HANA to get the FIRSTDATE....

I observed HANA Given last_date function but what about First_Date function? can i use it?

Regards,
