The question is two years old and you missed that he tried to create the table inside a function which is not allowed.

You cannot use DDL inside a function.

Simply create the temp table and let it exist in your tablespace. All data you insert into it will be usable from that session only. So there is no need to create and delete it for every transaction.
So you can just use:

SQL

INSERT INTO store_sales 
select * from tbl_folders

Since you have specified on commit delete rows, the data will be automatically deleted when you commit or rollback the transaction.
