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