在MySQL终端上粘贴以下MySQL命令后出现以下错误.这段代码是从项目的生产环境中获取的.我想根据生产环境的数据库更新本地数据库.

I got the below error after pasting the below MySQL command on MySQL terminal.This code I got it from my project's production environment.I want to update the local db according to the production env's db.

mysql> CREATE TABLE `cityguide_pointofinterest` (
    ->   `id` int(11) NOT NULL AUTO_INCREMENT,
    ->   `name` varchar(30) COLLATE utf8_danish_ci NOT NULL,
    ->   `vip` tinyint(1) NOT NULL,
    ->   `description` longtext COLLATE utf8_danish_ci NOT NULL,
    ->   `category_id` int(11) NOT NULL,
    ->   `email` varchar(254) COLLATE utf8_danish_ci,
    ->   `latitude` double NOT NULL,
    ->   `longitude` double NOT NULL,

    ->   KEY `cityguide_pointofi_category_id_8ab78aba_fk_cityguide_category_id` (`category_id`),
    ->   CONSTRAINT `cityguide_pointofi_category_id_8ab78aba_fk_cityguide_category_id` FOREIGN KEY (`category_id`) REFERENCES `cityguide_category` (`id`)
    -> ) ENGINE=InnoDB AUTO_INCREMENT=47 DEFAULT CHARSET=utf8 COLLATE=utf8_danish_ci;

错误1064(42000):您的SQL语法有错误；查看与您的MySQL服务器版本相对应的手册，以获取正确的语法，以在'(6)NOT NULL附近使用， date_modified datetime(6)NOT NULL， 第13行的views int(11)NOT NULL' mysql>/*！40101 SET character_set_client = @saved_cs_client */; 查询正常，受影响的0行(0.00秒)

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 '(6) NOT NULL, date_modified datetime(6) NOT NULL, views int(11) NOT NULL' at line 13 mysql> /*!40101 SET character_set_client = @saved_cs_client */; Query OK, 0 rows affected (0.00 sec)

推荐答案

我认为您的MYSQL版本为5.5或更低.

Your MYSQL version is 5.5 or below i think.

MySQL 5.7 支持TIME，DATETIME和TIMESTAMP值的小数秒支持，精度最高为微秒(6位数):

MySQL 5.7 has fractional seconds support for TIME, DATETIME, and TIMESTAMP values, with up to microseconds (6 digits) precision:

CREATE TABLE t1 (t TIME(3), dt DATETIME(6));

fsp值(如果给出)必须在0到6的范围内.值0表示没有小数部分.如果省略，则默认精度为0.(这与标准SQL默认值6不同，以便与以前的MySQL版本兼容.)

The fsp value, if given, must be in the range 0 to 6. A value of 0 signifies that there is no fractional part. If omitted, the default precision is 0. (This differs from the standard SQL default of 6, for compatibility with previous MySQL versions.)
