ARRAY_OVERLAP
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
The ARRAY_OVERLAP function allows for checking if two arrays overlap:
SELECT ARRAY[1, 2] && ARRAY[3, 4]
create.select(arrayOverlap(array(1, 2), array(2, 3))).fetch();
The result would look like this:
+---------------+ | array_overlap | +---------------+ | true | +---------------+
Dialect support
This example using jOOQ:
arrayOverlap(array(1, 2), array(2, 3))
Translates to the following dialect specific expressions:
Aurora Postgres, CockroachDB, Postgres, YugabyteDB
(ARRAY[1, 2] && ARRAY[2, 3])
DuckDB
array_length(array_intersect( ARRAY[1, 2], ARRAY[2, 3] )) > 0
