I like your approach to make others understand after writing each query and that too step by step in excel...Great keep it up....looking forward to see 1 video in every two days.....Please bring quality level sql questions.👍👍

Thanks for sharing.
Here's my approach on SQL server:
===========================================
with cte2 as (select *, ROW_NUMBER() over(partition by name order by (select 1)) rn
from names
cross apply string_split(name,' '))
select Max(First_name) First_name, Max(Middle_name) Middle_name, Max(Last_name) Last_name
from (select *,
case when rn = 1 then value end as First_name,
case when COUNT(name) over(partition by name) > 2 and rn = 2 then value end Middle_name,
case when COUNT(name) over(partition by name) < 3 and rn = 2 then value
when COUNT(name) over(partition by name) >= 3 and rn = 3 then value
end Last_name
from cte2) s1
group by name
===========================================

WITH cte AS (
SELECT
customer_name,
TRIM(value) AS part,
ROW_NUMBER() OVER (PARTITION BY customer_name ORDER BY (SELECT 1)) AS rn
FROM customers
CROSS APPLY STRING_SPLIT(customer_name, ' ')
)
SELECT
customer_name,
MAX(CASE WHEN rn = 1 THEN part END) AS first_name,
MAX(CASE WHEN rn = 2 THEN part END) AS middle_name,
MAX(CASE WHEN rn = 3 THEN part END) AS last_name
