When using php what value would I have to set the field for sex to so that it would push the data to the database. Also can yoyu give an example of the code.

How do you create a next and previous button using php and oracle as your database? For example, I have 100 records and I only want to show 30 records at a time. I really have no clue on how to do it. I know it can be done using php and mysql but our project requires us to use oracle as database.
