Question

I am getting following error when we are upgrading 5.0.45 to 5.1.42. Do I need to use mysql_upgrade
or mysqlcheck ?

Caused by: java.sql.SQLException: Column count of mysql.proc is wrong. Expected 20, found 16. Created with MySQL 50045, now running 50142. Please use mysql_upgrade to fix this error.

Answer 1

in mysql 5.1 4 additional columns were added for procedures. Seems that somehow your upgrade skipped that step and now you are getting error while importing data.

MySQL upgrade should help you solve that problem.
