Update multiple rows using WHERE IN where using one MYSQL query

I have a one query for select ids from table and another query for update the table values. These are the queries used.

for select ids

select id from table_1 where orderId = 41 AND status = 1

for update

UPDATE table_1 SET orderId = '17' WHERE id IN (1,2,3,4,5,6,.....,n);

This two queries working properly. But when try to this code its not working. I want to update orderId update 41 to 17 in all the records selected

UPDATE table_1 SET orderId = '17' WHERE id IN (select id from table_1 where orderId = 41 AND status = 1 );

This query is returns error. Any suggestion to correct this error. Thank You

The problem is that MySQL does not allow you to use the same table in subqueries in an update or delete. I think you can simplify the logic, so the subquery is not needed.

Why not just use this?

UPDATE table_1
    SET order_id = '17'
    WHERE order_id = 41 AND status = 1;

Note: If order_id is a number, use 17 not '17' -- don't mix data types.

This assumes that id is unique.

Alternatively, if you really need list of ids, you can also use a JOIN:

UPDATE table_1 t1 JOIN
       (SELECT tt1.*
        FROM table_1 tt1
        WHERE tt1.order_id = 41 AND tt1.status = 1
       ) tt1
       ON tt1.id = t1.id
    SET t1.order_id = 17;
