  • more complex queries: GROUP BY, aggregates, HAVING
  • Transactions (inserts and updates)
  • triggers
  • views
  • style
  • escaping to the procedural world: PL/SQL and Java executing inside the Oracle server
  • trees
  • handling dates in Oracle
  • limits in Oracle; how they will bite you and how to work around them
  • tuning, what to do when your query runs too slowly
  • data warehousing, what to do when your query doesn’t answer your questions
  • foreign and legacy data, making foreign Web sites look like local SQL tables
