请教关于MySQL里的CREATE TABLE的问题。请问如下建表语句那里出错了，问啥执行不了呢？谢谢！

建表语句：
mysql> CREATE TABLE IF NOT EXISTS company_user(
-> id int(10) UNSIGNED AUTO_INCREMENT NOT NULL PRIM
ARY KEY,
-> username VARCHAR(24) NOT NULL UNIQUE,
-> password VARCHAR(8) NOT NULL,
-> company_name VARCHAR(300) NOT NULL UNIQUE,
-> company_type VARCHAR(30) NOT NULL,
-> company_intro TEXT DEFAULT,
-> office_image TEXT,
-> register_date DATE NOT NULL
-> )ENGINE=InnoDB DEFAULT CHARSET utf8 COLLATE utf8_general_ci;

系统报错：
ERROR 1064 (42000): 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 '
office_image TEXT,
register_date DATE NOT NULL
)ENGINE=InnoDB DEFAU' at line 7

参考技术A CREATE TABLE IF NOT EXISTS company_user(
id int(10) UNSIGNED AUTO_INCREMENT NOT NULL PRIMARY KEY,
username VARCHAR(24) NOT NULL UNIQUE,
password VARCHAR(8) NOT NULL,
company_name VARCHAR(250) NOT NULL UNIQUE,
company_type VARCHAR(30) NOT NULL,
company_intro TEXT,
office_image TEXT,
register_date DATE NOT NULL
)ENGINE=InnoDB DEFAULT CHARSET utf8 COLLATE utf8_general_ci;本回答被提问者采纳

关于Oracle的create

create 的语法：

1. 此时是利用table_name2表的全部字段创建的table_name1;

create table  table_name1 (select * from table_name2);

2. 如果要选取几个字段就要用到AS；

create table table_name1 as select id,name from table_name2 (where .... order by ....);

好的解散！
