The vast majority of Oracle Sql books discuss some syntax, provide the barest rudiments of using Oracle Sql, and perhaps include a few simple examples. It might be enough to pass a survey course, or give you some buzz words to drop in conversation with real Oracle Dbas. But if you use Oracle Sql on a regular basis, you want much more. You want to access the full power of Sql to write queries in an Oracle environment. You want a solid understanding of what's possible with Oracle Sql, creative techniques for writing effective and accurate queries, and the practical, hands-on information that leads to true mastery of the language.
