INSERT INTO table_abc (a, b, c)
WITH values_to_insert (a, b, c) AS (
VALUES (1,2,3), (4,5,6), (7,8,9)
)
SELECT a, b, c
FROM values_to_insert
WHERE a = 4
;
See: http://www.postgresql.org/docs/9.2/interactive/sql-values.html
<http://www.postgresql.org/docs/9.2/interactive/sql-values.html> for more
detail on "VALUES". Basically it provides a way to build an on-the-fly
table and can be used wherever a normal table can be used (though usually it
takes some aliasing to get meaningful names).
