You can say what are # between sqlplus > (oracle) and sql (mysql) Well, sqlplus is just an Oracle client program that lets you run SQL queries against the Oracle db. I think what you are really after is what the differences between Oracle SQL and MySQL SQL are. A couple things come to mind: 1.) For CREATE TABLE, Oracle uses VARCHAR2, MySQL has VARCHAR 2.) For MySQL you need to create your tables as InnoDB tables if you are using transactions or foriegn keys (which I hope you are for a production application) 3.) MySQL does not support Oracle's notion of Sequences - in MySQL you do have AUTO_INCREMENT columns, but they are not as robust as sequences. 4.) MySQL does not support CHECK constraints inside CREATE TABLE clauses. I'm sure there are others, but as long as your application uses pretty generic SQL and you are not getting into Oracle-specific stuff you should be ok.
