Semantics

create_view

CREATE [ OR REPLACE ] VIEW qualified_name [ (column_list ) ] AS select

Create a view.

qualified_name

Specify the name of the view. An error is raised if view with that name already exists in the specified database (unless the OR REPLACE option is used).

column_list

Specify a comma-separated list of columns. If not specified, the column names are deduced from the query.

select

Specify a SELECT or VALUES statement that will provide the columns and rows of the view.

Examples

Create a sample table.

CREATE TABLE sample(k1 int, k2 int, v1 int, v2 text, PRIMARY KEY (k1, k2));

Insert some rows.

INSERT INTO sample(k1, k2, v1, v2) VALUES (1, 2.0, 3, 'a'), (2, 3.0, 4, 'b'), (3, 4.0, 5, 'c');

Create a view on the sample table.

CREATE VIEW sample_view AS SELECT * FROM sample WHERE v2 != 'b' ORDER BY k1 DESC;

Select from the view.

yugabyte=# SELECT * FROM sample_view;
 k1 | k2 | v1 | v2
----+----+----+----
  3 |  4 |  5 | c
  1 |  2 |  3 | a
(2 rows)
