Cast to JSON
------------

Casting from ``BOOLEAN``, ``TINYINT``, ``SMALLINT``, ``INTEGER``,
``BIGINT``, ``REAL``, ``DOUBLE`` or ``VARCHAR`` is supported.
Casting from ``ARRAY``, ``MAP`` or ``ROW`` is supported when the element type of
the array is one of the supported types, or when the key type of the map
is ``VARCHAR`` and value type of the map is one of the supported types,
or when every field type of the row is one of the supported types.
Behaviors of the casts are shown with the examples below::

SELECT CAST(NULL AS JSON); -- NULL
SELECT CAST(1 AS JSON); -- JSON '1'
SELECT CAST(9223372036854775807 AS JSON); -- JSON '9223372036854775807'
SELECT CAST('abc' AS JSON); -- JSON '"abc"'
SELECT CAST(true AS JSON); -- JSON 'true'
SELECT CAST(1.234 AS JSON); -- JSON '1.234'
SELECT CAST(ARRAY[1, 23, 456] AS JSON); -- JSON '[1,23,456]'
SELECT CAST(ARRAY[1, NULL, 456] AS JSON); -- JSON '[1,null,456]'
SELECT CAST(ARRAY[ARRAY[1, 23], ARRAY[456]] AS JSON); -- JSON '[[1,23],[456]]'
SELECT CAST(MAP_FROM_ENTRIES(ARRAY[('k1', 1), ('k2', 23), ('k3', 456)]) AS JSON); -- JSON '{"k1":1,"k2":23,"k3":456}'
SELECT CAST(CAST(ROW(123, 'abc', true) AS ROW(v1 BIGINT, v2 VARCHAR, v3 BOOLEAN)) AS JSON); -- JSON '[123,"abc",true]'
