Printing Camel Case Names while creating Database Objects in Oracle

If you want to put the CamelCase names to your database objects, your create object script should have been with in double quotes like below:

create table "temp_2"

(“col1”  number constraint "temp_2_pk" primary key, col2 number);

select * from "temp_2"

select * from user_tables where table_name ='temp_2'

Without double-quotes Oracle helpfully converts all identifiers to uppercase.
