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]) -- H2 EXISTS ( SELECT * FROM UNNEST(ARRAY[1, 2]) array_table (COLUMN_VALUE) INTERSECT SELECT * FROM UNNEST(ARRAY[2, 3]) array_table (COLUMN_VALUE) ) -- HSQLDB EXISTS ( SELECT * FROM UNNEST(ARRAY[1, 2]) array_table (COLUMN_VALUE) INTERSECT ALL SELECT * FROM UNNEST(ARRAY[2, 3]) array_table (COLUMN_VALUE) ) -- TRINO arrays_overlap( ARRAY[1, 2], ARRAY[2, 3] ) -- ACCESS, ASE, AURORA_MYSQL, BIGQUERY, DB2, DERBY, DUCKDB, EXASOL, FIREBIRD, HANA, INFORMIX, MARIADB, MEMSQL, MYSQL, -- ORACLE, REDSHIFT, SNOWFLAKE, SQLDATAWAREHOUSE, SQLITE, SQLSERVER, SYBASE, TERADATA, VERTICA /* UNSUPPORTED */
