①在ap1上执行rake db:migrate RAILS_ENV="ris"，从而向drizzle数据库中导入mry_production数据库。

这时出现如下的错误：

[root@rap1 mry]# rake db:migrate RAILS_ENV="ris"

(in /var/qp/mry)

RAILS_ENV

ris

== ?CreateContents: migrating =================================================

-- create_table(:contents, {:options=>"ENGINE=InnoDB DEFAULT CHARSET=utf8"})

rake aborted!

An error has occurred, all later migrations canceled:

Mysql::Error: You have an error in your SQL syntax; check the manual that corresponds to your Drizzle server version for the right syntax to use near 'CHARSET=utf8' at line 1: CREATE TABLE `contents` (`id` int(11) DEFAULT NULL auto_increment PRIMARY KEY) ENGINE=InnoDB DEFAULT CHARSET=utf8

(See full trace by running task with --trace)

此处错误提示的意思是：在drizzle中，不支持"CHARSET=utf8"这样的语法。

经过调查，在dirzzle中等同于"CHARSET=utf8"的语法是"COLLATE='utf8_general_ci'"。

且在drizzle中创建表格后，其默认的COLLATE都为'utf8_general_ci'。
