A non-critical business m/s is upgraded from 5.1 to 5.5. after entering the console, the data dictionary cannot be queried and the following error is reported: Cannot load from mysql. Proc. The table is probably specified upted The solution is very simple and runsMysql_upgradeCommand. This command will generate a text file mysql_upgrade_info in the Data Directory, which contains the upgraded database version. What makes me strange is that the upgra

The following error occurs when you perform mysql-related operations: Error 1548 (hy000): cannot load from mysql. Proc.

On the Linux terminal, execute the following command to fix the problem: #/Usr/local/MySQL/bin/mysql_upgrade-ur
