content text' at line 3

Answer 1

mysql提示语法和错，错误靠近“AS 用户ID”，COMMENT 关键字是注释，注释内容后面直接用引号就可以了

CREATE TABLE ak_ask (
id int(10) NOT NULL,
uid int(10) UNSIGNED DEFAULT NULL COMMENT '用户ID',
problem varchar(120) NOT NULL COMMENT '问题',
content text NOT NULL COMMENT '问题内容',
name varchar(30) NOT NULL COMMENT '名字',
qq int(12) UNSIGNED NOT NULL COMMENT 'qq号',
answer text COMMENT '回答',
area char(30) NOT NULL COMMENT '地区',
atime int(10) UNSIGNED NOT NULL COMMENT '提交时间',
display tinyint(1) UNSIGNED NOT NULL DEFAULT '0'
)

COMMENT 并不要 as
