Convert timestamp to date in Oracle SQL

Question

How can we convert timestamp to date?

The table has a field, start_ts which is of the timestamp format:

\'05/13/2016 4:58:1         


        

Answer 1

Try using TRUNC and TO_DATE instead

WHERE
    TRUNC(start_ts) = TO_DATE('2016-05-13', 'YYYY-MM-DD')

Alternatively, you can use >= and < instead to avoid use of function in the start_ts column:

WHERE
   start_ts >= TO_DATE('2016-05-13', 'YYYY-MM-DD')
   AND start_ts < TO_DATE('2016-05-14', 'YYYY-MM-DD')
