Coming to OpenWorld 2018? Be sure to visit the TidalScale booth in Moscone South and learn how to solve performance problems and lower costs with Software Defined Servers. Before you visit the booth, or if you can't make it this year, check out TidalScale at www.tidalscale.com. Be sure to click on the Solutions link and look through the Oracle resources.
The WHERE Clause servers two different purposes. One is to limit the records affected by a DML statement. The second to join two or more tables, view, or materialized views for DML.

The following links all have demonstrations of using the WHERE clause ... each in a different context.
