Oracle SQL High-Performance Tuning with CDROM Paperback - 1997

The complete developer's guide to optimizing Oracle SQL code. Optimizing SQL code is the no.1 factor in improving Oracle database performance. Yet most guides to Oracle tuning virtually ignore SQL. Until now. Oracle SQL High-Performance Tuning zeroes in on SQL, showing how to achieve performance gains of 100% or more in many applications. Expert Oracle developer Guy Harrison presents a detailed overview of SQL processing, and then introduces SQL tuning guidelines that improve virtually any application. Learn how to: Choose execution plans. Work with joins. Search for nulls and ranges. Trace SQL statement execution. Build indexes that support efficient queries. Optimize virtually all type of SQL including: views, hierarchical queries, table scans, GROUP BY, updates, subqueries, distributed SQL, and more. As databases grow, and ad hoc queries to data warehouses increase, optimizing SQL becomes even more critical. Harrison offers practical guidance on using Oracle's parallel query facility for large-volume queries, and shows when to use Oracle's PL/SQL instead of standard SQL. The book is replete with examples, showing poorly tuned SQL, how to fix it-and specific performance measureme
