(1) in case of insert into statement, complex data type will behave the same
way as other data types. only thing the user has to be careful about is the
delimiter of the data. Complex data will use the default delimiters. As we
are supporting only 2 levels, the default level 1 and level 2 delimiters
will be used. Please check the product document for already supporting level
1 and level 2 delimiters for complex data types.
(2) We are supporting complex data types as No dictionary column only. So no
need to discuss on dictionary part now.
