Greetings.
To my best knowledger, you can use Parameters only for QUERIES and DML,
but not for DDL statements.
Although you can have a look
at https://github.com/manticore-projects/MJdbcUtils which I wrote
exactly for this kind of challenges.
It rewrites your parameterised SQL Statement and I used it for ORACLE's
CREATE TABLE ... AS SELECT ... FROM (where the SELECT must not contain
parameters).
Good luck and cheers
