OBJECT function - Amazon Redshift
SyntaxArgumentsReturn typeExample

Amazon Redshift will no longer support the creation of new Python UDFs starting November 1, 2025. If you would like to use Python UDFs, create the UDFs prior to that date. Existing Python UDFs will continue to function as normal. For more information, see the blog post .

OBJECT function

Creates an object of the SUPER data type.

Syntax

OBJECT ( [ key1, value1 ], [ key2, value2 ...] )

Arguments

key1, key2

Expressions that evaluate to VARCHAR type strings.

value1, value2

Expressions of any Amazon Redshift data type except datetime types, since Amazon Redshift doesn't cast datetime types to the SUPER data type. For more information on datetime types, see Datetime types.

value expressions in an object don't need to be of the same data type.

Return type

SUPER

Example

-- Creates an empty object.
select object();

object
--------
{}
(1 row)
            
-- Creates objects with different keys and values.
select object('a', 1, 'b', true, 'c', 3.14);

object
---------------------------
{"a":1,"b":true,"c":3.14}
(1 row)
               
select object('a', object('aa', 1), 'b', array(2,3), 'c', json_parse('{}'));
               
object
---------------------------------
{"a":{"aa":1},"b":[2,3],"c":{}}
(1 row)
            
-- Creates objects using columns from a table.
create table bar (k varchar, v super);
insert into bar values ('k1', json_parse('[1]')), ('k2', json_parse('{}'));
select object(k, v) from bar;

object
------------
{"k1":[1]}
{"k2":{}}
(2 rows)
            
-- Errors out because DATE type values can't be converted to SUPER type.
select object('k', '2008-12-31'::date);

ERROR:  OBJECT could not convert type date to super
