Vista de tablas de PARADOX

Buen dia.

Se puede hacer vistas de tablas de Paradox, para no trabajar directamente con las tablas de mi base de datos.

Si se pueden crear:

CREATE VIEW

See also

A view creates a virtual table from a SELECT statement. You can look at just the data you need within this movable frame or window on the table, while the technical underpinnings are hidden. Instead of entering a complex qualified SELECT statement, the user simply selects a view.
CREATE VIEW describes a view of data based on one or more underlying tables in the database. The rows to return are defined by a SELECT statement that lists columns from the source tables. A view does not directly represent physically stored data. It is possible to perform select, project, join, and union operations on views as if they were tables.

CREATE VIEW enables users to create views on tables by using the following syntax:

CREATE VIEW view_name [ (column_name [, column_name]...)]

CREATE VIEW is supported in conjunction with the Client Data Repository (CDR). The CDR stores the SELECT statement that defines the view.
The "WITH CHECK OPTION" is supported to create a constrained view.
Views of Views are supported. However, the CASCADE/LOCAL view attribute is not supported, because all updateable views CASCADE the constraints.

Un Saludo.
