> The Trafodion SQL Reference Manual on wiki: http://trafodion.apache.org/docs/sql_reference/Trafodion_SQL_Reference_Manual.pdf, Page 119, 'Considerations for CREATE VOLATILE TABLE' explicitly says the following:
> "Statistics are not automatically updated for volatile tables. If you need statistics, you must explicitly run UPDATE STATISTICS."
> However, as shown in the following example, update statistics does not work for volatile tables.
> >>create schema mytest;
> --- SQL operation complete.
> >>set schema mytest;
> --- SQL operation complete.
> >>
> >>create volatile table mytable (a int);
> --- SQL operation complete.
> >>insert into mytable values (1);
> --- 1 row(s) inserted.
> >>select * from mytable;
> A
> -----------
>           1
> --- 1 row(s) selected.
> >>update statistics for table mytable on every column;
> *** ERROR[4082] Object TRAFODION.MYTEST.MYTABLE does not exist or is inaccessible.
