If you want the value from your timestamp column to come back as a date datatype  use something like this   select trunc my timestamp column  dd   as my date column from my table

In Oracle 11g  To get the complete date from the Timestamp  use this- Select TRUNC timestamp  FROM TABLE NAME   To get the Year from the Timestamp  use this- Select EXTRACT YEAR FROM TRUNC timestamp   from TABLE NAME   To get the Month from the Timestamp  use this- Select EXTRACT MONTH FROM TRUNC timestamp   from TABLE NAME   To get the Day from the Timestamp  use this- Select EXTRACT DAY FROM TRUNC timestamp   from TABLE NAME

This is exactly what TO DATE   is for  to convert timestamp to date   Just use TO DATE sysdate  instead of TO CHAR sysdate   YYYY MM DD-HH24-MI-SS-SSSSS     SQLFiddle demo  UPDATE   Per your update  your cdate column is not real DATE or TIMESTAMP type  but VARCHAR2  It is not very good idea to use string types to keep dates  It is very inconvenient and slow to search  compare and do all other kinds of math on dates   You should convert your cdate VARCHAR2 field into real TIMESTAMP  Assuming there are no other users for this field except for your code  you can convert cdate to timestamp as follows   BEGIN TRANSACTION  -- add new temp field tdate  ALTER TABLE mytable ADD tdate TIMESTAMP  -- save cdate to tdate while converting it  UPDATE mytable SET tdate   to date cdate   YYYY-MM-DD HH24 MI SS     -- you may want to check contents of tdate before next step     -- drop old field ALTER TABLE mytable DROP COLUMN cdate  -- rename tdate to cdate  ALTER TABLE mytable RENAME COLUMN tdate TO cdate  COMMIT    SQLFiddle Demo
