Francis, the data in a SQL database has no implicit order. So, you can't count on the data coming out in the same order in which you inserted it. The order in which data comes out of a SQL database can only be guaranteed by using an 'ORDER BY' clause on the SQL statement that brings it out of the DB.
Thus, if you want a different sort order than sorting by the keys you've provided, you probably have to add a 'sort' column to your table and use that column in the ORDER BY portion of your SELECT statements.

You can get tables names and columns names using information_schema.
And Information_schema contains following column names using which you can filter your results:
