Null Pointer Exception when updating user with subquery in UPDATE statement #80

I am encountering a null pointer exception when running the following SQL query to update the name of a user based on a subquery:

UPDATE t_user a, (SELECT ? AS id, ? AS name) b SET a.name = b.name WHERE a.id = b.id

when I run this query, I get a null pointer exception. Upon further investigation, I found that the subquery is returning null and causing the issue.
