      Used this in Oracle SQL Developer:

      SELECT COUNT(*) FROM DUAL WHERE EXISTS (
    SELECT * FROM ALL_OBJECTS WHERE OBJECT_TYPE = 'TABLE' AND OWNER = 'myschema' AND OBJECT_NAME = 'your_table_name')

      This will return either a 0 or 1 if your table exists or not in the ALL_OBJECTS records.
