Question

这是错误

java.sql.SQLSyntaxErrorException：SQL语法有错误；检查与您的MySQL服务器版本相对应的手册以获取正确的语法，以在第1行的'（'y'）或user_password ='y'）'附近使用

y是密码

以前的版本是MYSQL 6.3 现在是MYSQL 8.0.16

我已经找到了相应的代码

sql =
    " SELECT * " +
    " FROM user u, access " +
    " where u.user_id = access_user_id " +
    " and user_login_id = ? " +
    " and (user_password = password(?) " +
    " or user_password = ?) ";

我认为主要问题发生在这里。这些代码可以与mysql 6.3完全正常运行，但不能与mysql 8.0.16 我已经从官方网站上查看了手册，但没有帮助

请帮帮我。对不起，我的英语不好。
