mySQL 5.5.43 语法错误

Question

我正在进行 Mantis 数据库升级，在运行创建表命令时收到以下错误。有人可以帮我看看 mysql 语法有什么问题吗？

这是错误消息:

Schema CreateTableSQL ( )   BAD
CREATE TABLE (
email_id INTEGER UNSIGNED NOT NULL AUTO_INCREMENT,
email VARCHAR(64) NOT NULL DEFAULT '',
subject VARCHAR(250) NOT NULL DEFAULT '', 
submitted DATETIME NOT NULL DEFAULT '1970-01-01 00:00:01',
metadata LONGTEXT NOT NULL,
body LONGTEXT NOT NULL,
PRIMARY KEY (email_id) )
ENGINE=MyISAM

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '( email_id INTEGER UNSIGNED NOT NULL AUTO_INCREMENT, email ' at line 1

这是schema.php中创建表代码的一部分

$upgrade[] = Array('CreateTableSQL',Array(config_get('mantis_email_table'),"
email_id              I  UNSIGNED NOTNULL PRIMARY AUTOINCREMENT,
email                 C(64) NOTNULL DEFAULT \" '' \",
subject               C(250) NOTNULL DEFAULT \" '' \",
submitted     T NOTNULL DEFAULT '1970-01-01 00:00:01',
metadata              XL NOTNULL,
body                  XL NOTNULL
",Array('mysql' => 'ENGINE=MyISAM', 'pgsql' => 'WITHOUT OIDS')));

您尚未为表提供名称:

CREATE TABLE  # name is missing here

    ( email_id INTEGER UNSIGNED NOT NULL AUTO_INCREMENT
    , email VARCHAR(64) NOT NULL DEFAULT ''
    , subject VARCHAR(250) NOT NULL DEFAULT ''
    , submitted DATETIME NOT NULL DEFAULT '1970-01-01 00:00:01'
    , metadata LONGTEXT NOT NULL
    , body LONGTEXT NOT NULL
    , PRIMARY KEY (email_id) 
)ENGINE=MyISAM
