How to SELECT inside UPDATE in a MYSQL query - mysql

Question

Multiples posts asking about it already exist, solutions have been given and they worked for my previous queries.
But it won't work now that I try the same query to SELECT inside an UPDATE from the same table.
Here are the differents queries I tried :
UPDATE usersDB.random
SET total_partners =
(
SELECT total_partners FROM usersDB.random
WHERE year = 2022
)
WHERE uid = 1
and
UPDATE usersDB.random
SET total_partners =
(
SELECT total_partners
FROM usersDB.random
AS x
WHERE year = 2022
)
WHERE uid = 1
But I get this error message everytime :
Error Code: 1093. You can't specify target table 'random' for update
in FROM clause
The same query but with two differents table work tho :
UPDATE usersDB.random
SET total_partners =
(
SELECT COUNT(*)
FROM usersDB.partners AS x
)
WHERE (month = MONTH(CURRENT_DATE()) and year = YEAR(CURRENT_DATE())) OR uid = 1
How can I make it work when it's the same table ? Version of Mysql is 8.0
Here is how the table random looks like https://i.imgur.com/HYSS5DJ.png
I use Mysql Workbench to send the queries

Because you did not provide a simple test data Create Table/Insert Into (copypaste text) script I had to experiment with my own table scheme. See this with aTemp temporary table how I use two-level inner table.
Update person Set
city=(
Select Concat(now(),"-",aTemp.val1) from
(select count(*) as val1 from person) as aTemp
)
Where id=4
So out of my mind it may translate to this query.
UPDATE usersDB.random
SET total_partners=(
Select aTemp.val1 From
(SELECT count(*) as val1 FROM usersDB.random WHERE year=2022) aTemp
)
WHERE uid = 1
