1 table found.
(primary key columns are indicated with *)
I searched white book of Timesten11.2, but the columns of sys.tables in it is different from above.
also, in http://docs.oracle.com/cd/E13085_01/doc/timesten.1121/e17114/systemtables.htm#TTSYS379, I can't find it.
Thanks a lot .

Why do you need to know this? Is there some specific information you are trying to find?
Note the columns SYS[n] are not and never have been documented. Although they may contain values these are internal to Engineering and not generally made public. There is no guarantee that the use of a SYS[n] column will stay the same between releases as well.
