JSON_ARRAY
JSON_ARRAY constructs a JSON array from a list of data.
JSON_ARRAY (
    [value [{,value}...]]
    [NULL|ABSENT ON NULL]
    [RETURNING datatype]
)
value
Specifies one or more constants, table columns, or expressions. Only 100 values can be used in a single JSON_ARRAY statement.
NULL ON NULL | ABSENT ON NULL
Specifies how nulls are handled. NULL ON NULL inserts nulls as SQL nulls. ABSENT ON NULL omits null values. Default is ABSENT ON NULL.
RETURNING datatype
Specifies the data type of the result. Datatype can be any string data type. Default is varchar(4000).
Example:
SELECT JSON_ARRAY ('test', emp.unit, emp.name) FROM emp WHERE "row" = 1
returns:
["test"”, "1A", "Frank"]
["test", "1B", "Steve"]
