View synopsis


In the view synopsis shown below, the CREATE VIEW statement is used to create a view, if the REPLACE keyword is used, the view will be replaced if it already exists. View attribute names can be given explicitly, or they can be inherited from the SELECT statement:

CREATE [ OR REPLACE ] [ TEMP | TEMPORARY ] [ RECURSIVE ] VIEW name [ ( column_name [, ...] ) ]
    [ WITH ( view_option_name [= view_option_value] [, ... ] ) ]
    AS query
    [ WITH [ CASCADED | LOCAL ] CHECK OPTION ]

Note

The synopsis of materialized views differs from the view synopsis. Please refer to the Materialized views section for the materialized view synopsis.

This might be useful for implementing data authorization to restrict applications from accessing the password. Note that the view column names are inherited from the SELECT list, as shown by the \d in the account_information meta command:
