this       SELECT field datetime field  FROM database WHERE datetime field  gt   sysdate-1    will work  The question is  is the  datetime field  has the same format as sysdate    My way to handle that  use  to char    function  only works in Oracle    samples  previous day   select your column from your table where to char sysdate-1   dd mm yyyy     or  select extract day from date field                 extract month from date field                extract year from date field         as mydate from dual or a table  where extract day from date field    an int number and       extract month from date field    an int number and so on     comparing date   select your column from your table where to char a datetime column   dd mm yyyy    gt  or  lt  or  gt   or  lt   to char sysdate   dd mm yyyy     time range between yesterday and a day before yesterday   select your column from your table where to char a datetime column   dd mm yyyy    gt  or  lt  or  gt   or  lt   to char sysdate-1   dd mm yyyy   and to char a datetime column   dd mm yyyy    gt  or  lt  or  gt   or  lt   to char sysdate-2   dd mm yyyy     other time range variation  select your column from your table where  to char a datetime column   dd mm yyyy   is between to char sysdate-1   dd mm yyyy    and to char sysdate-2   dd mm yyyy

You can remove the time part of a date by using TRUNC   select field datetime field    from database  where datetime field  gt   trunc sysdate-1  DD      That query will give you all rows with dates starting from yesterday  Note the second argument to trunc    You can use this to truncate any part of the date     If your datetime fied contains  2011-05-04 08 23 54   the following date will be returned  trunc datetime field   HH24     gt  2011-05-04 08 00 00 trunc datetime field   DD       gt  2011-05-04 00 00 00 trunc datetime field   MM       gt  2011-05-01 00 00 00 trunc datetime field   YYYY     gt  2011-00-01 00 00 00

Im a bit confused about this part  TO DATE TO CHAR CURRENT DATE   YYYY-MM-DD    YYYY-MM-DD     What were you trying to do with this clause    The format that you are displaying in your result is the default format when you run the basic query of getting date from DUAL   Other than that  i did this in your query and it retrieved the previous day   SELECT  CURRENT DATE - 1   FROM Dual   Do let me know if it works out for you and if not then do tell me about the problem  Thanks and all the best

Simple solution and understanding  To answer the question    SELECT field datetime field  FROM database WHERE TO CHAR date field   YYYYMMDD     TO CHAR SYSDATE-1   YYYYMMDD      Some explanation   If you have a field that is not in date format but want to compare using date i e  field is considered as date but in number format e g  20190823  YYYYMMDD   SELECT   FROM YOUR TABLE WHERE ID DATE   TO CHAR SYSDATE-1   YYYYMMDD      If you have a field that is in date timestamp format and you need to compare  Just change the  format  SELECT TO CHAR SYSDATE-1   YYYY-MM-DD HH24 MI SS    FROM DUAL   IF you want to return it to date format  SELECT TO DATE TO CHAR SYSDATE-1   YYYY-MM-DD HH24 MI SS     YYYY-MM-DD HH24 MI SS   AS NEW DATE  FROM DUAL   Conclusion   With this knowledge you can convert the filed you want to compare to a YYYYMMDD or YYYY-MM-DD or any year-month-date format then compare with the same sysdate format
