Create a view
CREATE [TEMP | TEMPORARY] VIEW [IF NOT EXISTS] [database-name.] view-name AS select-statement
The CREATE VIEW command assigns a name to a prepackaged SELECT statement. Once the view is created, it can be used in the FROM clause of another SELECT in place of a table name.
The TEMP or TEMPORARY keyword means the view that is created is visible only to the process that opened the database and is automatically deleted when the database is closed.
If a database-name is specified, then the view is created in the named database. It is an error to specify both a database-name and the TEMP keyword, unless the database-name is temp. If no database name is specified, and the TEMP keyword is not present, the table is created in the main database.
You cannot COPY, DELETE, INSERT or UPDATE a view. Views are read-only in QDB. However, in many cases you can use a TRIGGER on the view to accomplish the same thing. Views are removed with the DROP VIEW command.
