MYSQL 8.0 sql_mode NO_AUTO_CREATE_USER 的问题

在Mysql 8.0中

sql_mode= NO_AUTO_CREATE_USER

已经被废弃了。

In MySQL 8.0.11, several deprecated features related to account management have been removed, such as use of the GRANT statement to modify nonprivilege characteristics of user accounts, the NO_AUTO_CREATE_USER SQL mode, the PASSWORD() function, and the old_passwords system variable.

Replication from MySQL 5.7 to 8.0 of statements that refer to these removed features can cause replication failure. Applications that use any of the removed features should be revised to avoid them and use alternatives when possible, as described in Features Removed in MySQL 8.0.

To avoid a startup failure on MySQL 8.0, remove any instance of NO_AUTO_CREATE_USER from sql_mode system variable settings in MySQL option files.

Loading a dump file that includes the NO_AUTO_CREATE_USER SQL mode in stored program definitions into a MySQL 8.0 server causes a failure. As of MySQL 5.7.24 and MySQL 8.0.13, mysqldump removes NO_AUTO_CREATE_USER from stored program definitions. Dump files created with an earlier version of mysqldump must be modified manually to remove instances of NO_AUTO_CREATE_USER.
