根据rowid查找所属的对象号、文件号、块号、行号-还是简单一点吧

select rowid,
       dbms_rowid.rowid_object(rowid) obj#,
       dbms_rowid.rowid_block_number(rowid) block#,
       dbms_rowid.rowid_relative_fno(rowid) file#,
       dbms_rowid.rowid_row_number(rowid) row#
  from scott.emp;

ROWID                    OBJ#     BLOCK#      FILE#       ROW#
