Do you really have a column named "DATE"? That is a reserved word in Oracle-- you cannot (easily) use it as a column name

e options
SQL> create table abc (
  2    date timestamp(6)
  3  );
  date timestamp(6)
ERROR at line 2:
ORA-00904: : invalid identifierIt wouldn't be helpful to have a column named DATE either.
If you have a table ABC and a column TABLE_TIMESTAMP_FIELD, you would simply do as Bruce has suggested
SELECT *
  FROM abc
WHERE table_timestamp_field > systimestamp - 1will give you all rows from ABC where TABLE_TIMESTAMP_FIELD is from the last 24 hours. If you want all rows where TABLE_TIMESTAMP_FIELD was some time yesterday
SELECT *
  FROM abc
WHERE table_timestamp_field >= trunc(systimestamp - 1)
    AND table_timestamp_field < trunc(systimestamp)Justin
