CREATE OR REPLACE VIEW is similar, but if a view of the same name already exists, it is replaced. CREATE TABLE order_details ( order_detail_id integer CONSTRAINT order_details_pk PRIMARY KEY, order_id integer NOT NULL, order_date date, quantity integer, notes varchar(200) ); This PostgreSQL CREATE TABLE example creates a table called order_details which has 5 columns and one primary key: Its contents are the resultant of base table.

Instead, the query is run every time the view is referenced in a query. The Sku parameter value follows the convention pricing-tier_compute-generation_vCores as shown in the following examples.-Sku B_Gen5_1 maps to Basic, Gen 5, and 1 vCore. Stored Procedures that do not have parameters (arguments) are called “static”. Instead, the query is run every time the view is referenced in a query. CREATE MATERIALIZED VIEW defines a materialized view of a query. Each PostgreSQL instance’s “log_directory” can then be pointed to its designated folder. The function get_film_count has two main sections: header and body.. In the function select from the view inner-joined with the type IDs in the user defined table. This option is the smallest SKU available.-Sku GP_Gen5_32 maps to General Purpose, Gen 5, and 32 vCores.-Sku MO_Gen5_2 maps to Memory Optimized, Gen 5, and 2 vCores.
