Temporary tables are often used in applications for processes that are difficult to complete in a single pass. They are widely used in SQL Server development and can be local and global. In Oracle temporary tables are created with a static global definition, but are used to hold temporary local content. But is this the only difference in temporary tables in Oracle and SQL Server? What about the performance impacts/gains for using temporary tables, and does this differ in Oracle and SQL Server?

Once again Jonathan Lewis (Oracle Ace Director, OakTable Network) and Grant Fritchey (Microsoft SQL Server MVP) will host a live discussion on Oracle and SQL Server, this time in relation to temporary tables.

Will they agree on some common ground? Or will it be an out and out argument? Either way, be prepared for a lively exchange that will not only entertain, but will teach you key concepts on Oracle and SQL Server.

A Q+A session with Jonathan and Grant will follow the presentation.
