Question

我在运行SQL数据库时遇到问题，我想创建一个像数据库一样的youtube。我收到了这个错误。

CREATE TABLE `Like` (   `video_id` int(5) NOT NULL DEFAULT '0',   `customer_id` int(6) NOT NULL DEFAULT '0',   `rating` int(1) NOT NULL DEFAULT '0',   `date` date NOT NULL DEFAULT '0000-00-00',   PRIMARY KEY  (`video_id`,`customer_id`),   KEY `date` (`date`),   KEY `video_id` (`video_id`),   KEY `customer_id` (`customer_id`),   KEY `rating` (`rating`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1
Error report -
SQL Error: ORA-00911: invalid character
00911. 00000 -  "invalid character"'

*Cause:    identifiers may not start with any ASCII character other than
           letters and numbers.  $#_ are also allowed after the first
           character.  Identifiers enclosed by doublequotes may contain
           any character other than a doublequote.  Alternative quotes
           (q'#...#') cannot use spaces, tabs, or carriage returns as
           delimiters.  For all other contexts, consult the SQL Language
           Reference Manual.
*Action:

CREATE TABLE `movies` (   `id` int(5) NOT NULL DEFAULT '0',   `year` int(4) DEFAULT '0',   `title` varchar(255) NOT NULL DEFAULT '',   PRIMARY KEY  (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1;

  CREATE TABLE `Channel` (   `movie_id` int(5) NOT NULL DEFAULT '0',   `customer_id` int(6) NOT NULL DEFAULT '0',   KEY `movie_id` (`movie_id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1; 

 CREATE TABLE `qualifying` (   `customer_id` int(6) NOT NULL DEFAULT '0',   `date` date NOT NULL DEFAULT '0000-00-00',   `movie_id` int(5) NOT NULL DEFAULT '0',   KEY `movie_id` (`movie_id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1; 

 CREATE TABLE `Like` (   `video_id` int(5) NOT NULL DEFAULT '0',   `customer_id` int(6) NOT NULL DEFAULT '0',   `rating` int(1) NOT NULL DEFAULT '0',   `date` date NOT NULL DEFAULT '0000-00-00',   PRIMARY KEY  (`video_id`,`customer_id`),   KEY `date` (`date`),   KEY `video_id` (`video_id`),   KEY `customer_id` (`customer_id`),   KEY `rating` (`rating`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1;

Answer 1

您的主要问题是您正在尝试在Oracle数据库上运行带有MySQL语法的SQL脚本（您显然是在Oracle数据库上，因为您收到ORA-00911错误）。

您可以使用Oracle语法编写脚本，也可以更改数据库并使用MySQL。

Answer 2

从您的错误消息和脚本中可以清楚地看到，您正试图在Mysql数据库中运行Oracle表脚本，这就是为什么你收到了错误。

您需要在表脚本中进行一些更改，以便在Oracle数据库中进行更改

将back-ticks替换为double quotes(")
将int(N)数据类型替换为Number(P)

示例

CREATE TABLE "like"
  ( 
     "video_id"   Number(10) NOT NULL DEFAULT '0', 
     "customer_id"Number(10) NOT NULL DEFAULT '0', 
     "rating"     Number(10) NOT NULL DEFAULT '0', 
     "date"       DATE NOT NULL DEFAULT '0000-00-00', 
     CONSTRAINT video_customers_pk PRIMARY KEY ("video_id", "customer_id")
     KEY "date"("date"),  -- Not sure how to change this in oracle
     KEY video_id("video_id"), 
     KEY customer_id("customer_id"), 
     KEY rating("rating") 
  )

注意：我不确定KEY video_id("video_id")

中Oracle的等效内容
