Porting file from MySQL to Oracle Express 10g - mysql

Question

after starting (and almost finishing) a database project for school, I found out I was supposed to use Oracle Express instead of MySQL. So when I brought in the code I had written from mysql to oracle, everything stopped working. I'm not too familiar with oracle databases but I assumed their syntax is quite simaler to MySqls.
Are there any structures in this file that are different in oracle DBs?
anything you guys can see would help. Thanks!

Answer 1

In Oracle, privileged users (such as SYS) can create other users. That would look like this:
SQL> connect sys/pwd as sysdba
Connected.
SQL> select tablespace_name from user_tablespaces;
TABLESPACE_NAME
------------------------------
SYSTEM
SYSAUX
UNDOTBS1
TEMP
USERS
SQL> create user so_test identified by test
2 default tablespace users
3 temporary tablespace temp
4 quota unlimited on users;
User created.
SQL> grant create session, create table, create view to so_test;
Grant succeeded.
Now, connect as newly created user and run code (I fixed); later I'll post code you can reuse. There's no drop if exists in Oracle, so I'm just dropping those tables (paying attention to FK constraints!) and ignoring dropping errors.
Other errors include:
use varchar2, not varchar (that's not exactly an error, but - Oracle recommends it)
use single quotes for strings, not double quotes
either specify date format mask (such as to_date('2015/03/21', 'yyyy/mm/dd')) or use date literal (e.g. date '2015-03-21') or alter session and specify desired format
terminate all commands with semi-colon
insert into should be used for each row separately, unless you use insert all or insert into ... select ... from
OK, here we go:
SQL> connect so_test/test
Connected.
