View Editor

Use the View Editor to view, create, or alter views.

About Views

A view is a query that is named in the database so that it can be used as if it were a table. It can be thought of as a virtual table in the database whose contents are defined by the Select query.

You can use views to rearrange, filter and select the way you see data in tables without creating any copies of that data. Views help make data access simpler by hiding complexities. They can also help separate data for different users as a security measure.

SQL Navigator’s view editor makes it easy to create and alter views. Although you won’t need to type any PL/SQL code when editing views in SQL Navigator, you should be familiar with Oracle rules and guidelines for using views.

The attributes of this database object are described in Oracle documentation.
