起因是原来mysql是5.0.47的，后来想用分区表，故整个库导出，

然后倒入5.1.51的环境中，但是在创建存储过程中出现如下错误：

1558 - Column count of mysql.proc is wrong. Expected 20, found 16

 

1 ：保险一点先dump或者冷备份：

mysqldump -uroot -p111111 --quick --master-data=1 --all-databases --flush-logs --lock-tables >

 

2解决办法:

使用命令：mysql_upgrade就可以解决

 

mysql_upgrade -u root --datadir=/var/lib/mysql/ --basedir=/ --password=123456

 

下面是我操作的过程：

[root@db lib]# mysql_upgrade -u root -p111111 -hdb --datadir=/var/lib/mysql/ --basedir=/

mysql_upgrade: the '--datadir' option is always ignored

mysql_upgrade: the '--basedir' option is always ignored
