Summary
Today's lesson explains Oracle's extension to the standard language of SQL. These commands are only a fraction of what is available to you in SQL*Plus. If you use Oracle's products, check your database documentation, take the knowledge that you have learned here, and explore the endless possibilities that lie before you. You will find that you can accomplish almost any reporting task using SQL*Plus rather than by resorting to a procedural programming language.
If you are not using Oracle products, use what you have learned today to improve the ways you retrieve data in your implementation. Most major implementations have extensions, or enhancements, to the accepted standard language of SQL.
