How to extract only date value from date field in Oracle? [duplicate]

Answer 1

you can use TRUNC

For example :

SELECT * 
  FROM table 
 WHERE TRUNC(table.daterecord) = TO_DATE('03-Mar-2010', 'DD-MON-RRRR')

Answer 2

see this SO for suggestions of "How to correctly handle dates in queries constraints"?

In addition to the answers already provided, I would suggest using a range since this is more easily indexable:

SELECT * 
  FROM table 
 WHERE table.daterecord >= TO_DATE('03-Mar-2010', 'DD-MON-RRRR')
   AND table.daterecord < TO_DATE('04-Mar-2010', 'DD-MON-RRRR')

Answer 3

Yes you can use TRUNC function.

SELECT * 
  FROM table 
 WHERE TRUNC(table.daterecord) = TO_DATE('03-Mar-2010', 'DD-MON-RRRR')
