Use QUALIFY clause for first row in each ID.

     Sel id,amt from 
     QUALIFY RANK () OVER
     (
     PARTITION BY ID
     ORDER BY
     Amt ) = 1

Choose the best column for order by clause and the way you want to order like desc and asec order.

Best practice to choose the date column in history tables.


Regards,

Ramu.
