So, CSV would be a good idea. I just thinking of a better idea to eliminate manual tasks it involves here. And reading from CSV, that I can manage with phpCodes or using the params in MySQL.

I dont know a better way to do that. The strategy depends on how complicated the database is. If it is single table, then Oracle can export that to a CSV file which MySQL can import. You simply have to make sure the column types match. If it is more complex, then you need to spend some time translating the relationships from the Oracle schema into a MySQL schema. There is no one to one correspondence here, in spite of the promises of the SQL standards. Once you have done that, you may still be able to use the CSV files, but will need to determine what order to import them and how to restore the relevant indexes.

Extract to csv/XML?

[PHP] Oracle's dump to MySQL
I found this command from one guy for importing Oracle's dump to MySQL Shell> mysql -uroot db_name -vvf < oracle_dump.dmp But, v is for verbose and f is for force continuation. Anyone worked with Oracle and MySQL?
