CREATE LOCAL TEMPORARY VIEW

Creates or replaces a local temporary view. Views are read only, so they do not support insert, update, delete, or copy operations. Local temporary views are session-scoped, so they are visible only to their creator in the current session. Vertica drops the view when the session ends.

Vertica does not support global temporary views.

Syntax

CREATE [OR REPLACE] LOCAL TEMP[ORARY] VIEW view [ (column[,…] ) ] AS query

Parameters

OR REPLACE Specifies to overwrite the existing view view‑name. If you omit this option and view‑name already exists, CREATE VIEW returns an error.
view

Identifies the view to create, where view conforms to conventions described in Identifiers. It must also be unique among all names of sequences, tables, projections, views, and models within the same schema.
column[,…] List of up to 9800 names to use as view column names. Vertica maps view column names to query columns according to the order of their respective lists. By default, the view uses column names as they are specified in the query.
AS query

A SELECT statement that the temporary view executes. The SELECT statement can reference tables, temporary tables, and other views.

Example

The following CREATE LOCAL TEMPORARY VIEW statement creates the temporary view myview. This view sums all individual incomes of customers listed in the store.store_sales_fact table, and groups results by state:

=> CREATE LOCAL TEMP VIEW myview AS
   SELECT SUM(annual_income), customer_state FROM public.customer_dimension
     WHERE customer_key IN (SELECT customer_key FROM store.store_sales_fact)
     GROUP BY customer_state
     ORDER BY customer_state ASC;

The following example uses the temporary view myview with a WHERE clause that limits the results to combined salaries greater than $2 billion:

=> SELECT * FROM myview WHERE SUM > 2000000000;
