Answer 1

Please convert step by step. for example
(1) remove inverted quotation mark ( ` )
(2) modify constraints syntax (PRIMARY KEY,UNIQUE KEY, KEY etc.) to [url http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14200/clauses002.htm#g1053592]Oracle constraints.
(3) modify some datatype to [url http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14200/sql_elements001.htm#i45441]Oracle datatype
(4) think how to convert auto_increment ([url http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_6015.htm#i2067093]Sequence, [url http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_7004.htm#i2235611]Beffore Trigger etc. on Oracle)
