Extracting only date from a datetime field

In Oracle, to extract only the date from a datetime field, use the code below:

 select * from table_name where trunc(field_name) < = '2013-08-01'; 

Suppose your field UPDATE_DTTM has datetime stamp of a transaction – say ‘2013-08-01 02:30:31’

 select * from table_name where UPDATE_DTTM < = '2013-08-01'; 

would not return any rows. Because, by default in Oracle, ‘2013-08-01’ represents ‘2013-08-01 00:00:00’


 select * from table_name where trunc(UPDATE_DTTM) < = '2013-08-01'; 

would return a row, since only the date is being compared.

Have fun 🙂
