get a row where have list of array in SQL code example
Example: get a row where have list of array in SQL
CREATE TABLE my_table (
id serial PRIMARY KEY,
numbers INT []
);
INSERT INTO my_table (numbers) VALUES ('{2, 3, 4}');
INSERT INTO my_table (numbers) VALUES ('{2, 1, 4}');
-- which means --
test=# select * from my_table;
id | numbers
----+---------
1 | {2,3,4}
2 | {2,1,4}
(2 rows)
To check if an array contains parts of another array, you would use the && operator
&& -- overlap (have elements in common) -- ARRAY[1,4,3] && ARRAY[2,1] --> true
SELECT * FROM my_table WHERE numbers && '{1,2}'::int[];
To check if an array contains all members of another array, you would use the @> operator
@> -- contains -- ARRAY[1,4,3] @> ARRAY[3,1] --> true
SELECT * FROM my_table WHERE numbers @> '{1,2}'::int[];
