DISTINCT predicate (degree > 1)

Applies to ✅ Open Source Edition   ✅ Express Edition   ✅ Professional Edition   ✅ Enterprise Edition

The DISTINCT predicate is also supported for row value expressions of degree higher than 1. If your database does not support row value expression comparison predicates, jOOQ emulates them the way they are defined in the SQL standard:

(FIRST_NAME, LAST_NAME) IS DISTINCT FROM ('John', 'Doe')
(FIRST_NAME, LAST_NAME) IS NOT DISTINCT FROM ('John', 'Doe')
row(AUTHOR.FIRST_NAME, AUTHOR.LAST_NAME).isNotDistinctFrom("John", "Doe")
row(AUTHOR.FIRST_NAME, AUTHOR.LAST_NAME).isNotDistinctFrom("John", "Doe")

Dialect support

This example using jOOQ:

row(AUTHOR.FIRST_NAME, AUTHOR.LAST_NAME).isNotDistinctFrom("John", "Doe")

Translates to the following dialect specific expressions:

ASE, Exasol, Oracle, SQLDataWarehouse, SQLServer, Vertica

EXISTS (
  SELECT AUTHOR.FIRST_NAME, AUTHOR.LAST_NAME
  INTERSECT
  SELECT 'John', 'Doe'
)

Aurora MySQL, MariaDB, MySQL

(AUTHOR.FIRST_NAME, AUTHOR.LAST_NAME) <=> ('John', 'Doe')

Aurora Postgres, BigQuery, CockroachDB, DuckDB, H2, HSQLDB, Postgres, Snowflake, Trino, YugabyteDB

(AUTHOR.FIRST_NAME, AUTHOR.LAST_NAME) is not distinct from ('John', 'Doe')
