I tried:
UPDATE giveaways SET winner = '1' WHERE ID = (SELECT MAX(ID) FROM giveaways) But it gives:
#1093 - You can't specify target table 'giveaways' for update in
FROMclause
This article seems relevant but I can't adapt it to my query. How can I get it to work?

MySQL is an open source relational database management system. For WordPress sites, that means it helps you store all your blog posts, users, plugin information, etc. It stores that information in separate “tables” and connects it with “keys”, which is why it's relational.
SQL is a query programming language that manages RDBMS. MySQL is a relational database management system that uses SQL. SQL is primarily used to query and operate database systems. MySQL allows you to handle, store, modify and delete data and store data in an organized way.
MySQL is a database management system. To add, access, and process data stored in a computer database, you need a database management system such as MySQL Server.
In terms of data security, the SQL server is much more secure than the MySQL server. In SQL, external processes (like third-party apps) cannot access or manipulate the data directly. While in MySQL, one can easily manipulate or modify the database files during run time using binaries.
Based on the information in the article you linked to this should work:
update giveaways set winner='1' where Id = (select Id from (select max(Id) as id from giveaways) as t) If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
