Error 1548 (hy000): cannot load from mysql. Proc. The table is probably updated upted

Google was informed that the problem was due to upgrades or data version migration. It suddenly occurred to me that the data of MySQL was migrated to MySQL some time ago. It was a sin. On the Linux terminal, execute the following command to fix the problem:

#/Usr/local/MySQL/bin/mysql_upgrade-uroot-PYoupassword

#/Usr/local/MySQL/bin/mysqlcheck -- all-databases-uroot-PYoupassword// After the preceding command is successfully executed, check again whether there are any errors.
