ARRAY_REPLACE

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

The ARRAY_REPLACE function allows for replacing all occurrences of an element by another value in an array:

SELECT array_replace(ARRAY[1, 2, 2, 3], 2, -1)
create.select(arrayReplace(array(1, 2, 2, 3), val(2), val(-1))).fetch();

The result would look like this:

+----------------+
| array_replace  |
+----------------+
| [1, -1, -1, 3] |
+----------------+

Dialect support

This example using jOOQ:

arrayReplace(array(1, 2, 2, 3), val(2), val(-1))

Translates to the following dialect specific expressions:

Aurora Postgres, CockroachDB, Postgres, YugabyteDB

array_replace(
  ARRAY[1, 2, 2, 3],
  2,
  -1
)

H2, HSQLDB

(
  SELECT array_agg(CASE
    WHEN x IS NOT DISTINCT FROM 2 THEN -1
    ELSE x
  END ORDER BY o)
  FROM UNNEST(ARRAY[1, 2, 2, 3]) WITH ORDINALITY t (x, o)
)

transform(
  ARRAY[1, 2, 2, 3],
  e -> CASE
    WHEN e IS NOT DISTINCT FROM 2 THEN -1
    ELSE e
  END
