JSON_ARRAY

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

The JSON_ARRAY function is used to produce simple JSON arrays from scalar values, without aggregation(see also JSON_ARRAYAGG).

SELECT json_array(author.first_name, author.last_name)
FROM author

create.select(jsonArray(AUTHOR.FIRST_NAME, AUTHOR.LAST_NAME))
      .from(AUTHOR)
      .fetch();

The result would look like this:

+----------------------+
| json_array           |
+----------------------+
| ["Paulo", "Coelho"]  |
| ["George", "Orwell"] |
+----------------------+

Dialect support

This example using jOOQ:

jsonArray(val(1), val(2))

Translates to the following dialect specific expressions:

json_build_array(CAST(1 AS int), CAST(2 AS int))

json_array(1, 2)

toJSONString(tuple(1, 2))

json_build_array(CAST(1 AS int4), CAST(2 AS int4))

array_construct(coalesce(
  to_variant(1),
  parse_json('null')
), coalesce(
  to_variant(2),
  parse_json('null')
))

json_modify(
  json_modify('[]', 'append $', 1),
  'append $',
  2
)

CAST(ARRAY[
  CAST(1 AS json),
  CAST(2 AS json)
] AS json)

/* UNSUPPORTED */
