Create a ROW with no fields?

[alancai98]

Is there any way to create a ROW with no fields? When I pass no fields to ROW,

-- In Trino
SELECT ROW();

I get the following error:

FUNCTION_NOT_FOUND: line 1:8: Function 'row' not registered

In some other DBs with a type similar to Trino's ROW, I can create an empty structure with no fields. For example, in Redshift, I can create an OBJECT (similar to Trino's ROW) with no fields.

-- In Redshift
SELECT OBJECT() AS obj

Output:

obj |
-----
{}
