Exception occurs after migrating the database, the stored procedure cannot be used

Error occurred while using stored procedures due to relocation of database

Cause: Database Role Permissions Reason

such as: My original database user name when ABC, but now the new database does not change the user name

Workaround: Create the user name on the new database and use the user name to create a new stored procedure and table

Code: Grant all privileges on * * to ' user name ' @ '% ' identified by ' newpassword ';
