从Mac命令行将.sql文件导入到MySQL中。尝试使用mysql -u root -p db_name > path/to/dbfile.sql。

Question

我曾试过通过命令行来实现。

mysql -u root -p db_name > ~/Documents/db_name.sql 

我已经尝试过使用mysqlimport进行操作

mysqlimport -u root -p db_name ~/Documents/db_name.sql 

我已经尝试在正确的目录下使用文件名来执行两种方式。

我已经尝试使用以下方式登录mysql：

mysql -u root -p
use db_name;
source ~/Documents/db_name.sql;
(nothing happens - no response)
(tried with absolute path - no response)
\. ~/Documents/db_name.sql
(nothing happens)

我感觉好像少了点什么。根据过去30分钟的谷歌搜索和尝试，这似乎是一个琐碎的操作。

最终，我不得不将整个.sql文件复制并粘贴到mysql shell中，同时使用正确的数据库。

我感觉自己像个穴居人。请帮忙。

.sql文件的内容是什么？ - wchiquito

@wchiquito 正在更新中。 - vampiire

Answer 1

为了导入一个mysqldump sql文件，您应该使用mysql命令：

mysql -u root -p db_name < ~/Documents/db_name.sql

mysqlimport实用程序用于将文本文件中的数据插入到数据库中，它是LOAD DATA INFILE SQL语句的封装器。来自mysqlimport文档：

mysqlimport客户端提供了一个命令行接口来执行LOAD DATA INFILE SQL语句。大多数mysqlimport选项直接对应于LOAD DATA INFILE语法的子句。请参见第13.2.6节，“LOAD DATA INFILE Syntax”。

我执行了以下命令：mysql -u root -p db_name > ~/Documents/db_name.sql，后来意识到错误并使用了<。 - vampiire

你的 SQL 转储文件以 USE movie-buff; 开始，这意味着你已经拥有一个现有的 movie-buff 数据库。 - marcell

是的，它肯定已经被创建了。我一直在检查它的表格以查看它是否有效。它不断输出“空集”。 - vampiire

你确定你的 directors 表是空的吗？根据你的 SQL 文件，该表应该已经被创建 (CREATE TABLE ...) 并插入了数据 (INSERT INTO ...)。 - marcell

ERROR 1049 (42000): Unknown database 'db_name' - user12690225

Answer 2

我无法重现这个问题：

文件：~/Documents/db_name.sql

CREATE DATABASE IF NOT EXISTS `movie-buff`;

USE `movie-buff`;

-- Table structure for table `directors`
--

CREATE TABLE IF NOT EXISTS `directors` (
  `director_id` int(11) NOT NULL,
  `first` varchar(60) DEFAULT NULL,
  `last` varchar(60) DEFAULT NULL,
  `country` varchar(100) DEFAULT NULL
) ENGINE=InnoDB AUTO_INCREMENT=10 DEFAULT CHARSET=latin1;

--
-- Dumping data for table `directors`
--

INSERT INTO `directors` (`director_id`, `first`, `last`, `country`)
VALUES
(1, 'Jean-Pierre', 'Jeunet', 'France'),
(2, 'Jean', 'Renoir', 'France'),
(3, 'Akira', 'Kurosawa', 'Japan'),
(4, 'Jane', 'Campion', 'New Zealand'),
(5, 'Sally', 'Potter', 'UK'),
(6, 'Kasi', 'Lemmons', 'USA'),
(7, 'Ava', 'DuVernay', 'USA'),
(8, 'Todd', 'Haynes', 'USA'),
(9, 'Marleen', 'Gorris', 'Netherlands');

MySQL:

mysql> source ~/Documents/db_name.sql
Database changed
Query OK, 0 rows affected (0.01 sec)

Query OK, 9 rows affected (0.00 sec)
Records: 9  Duplicates: 0  Warnings: 0

它也适用于以下情况：

• mysql> \. ~/Documents/db_name.sql
• $ mysql -u user -p movie-buff < ~/Documents/db_name.sql

更新

在mysql> source ~/Documents/db_name.sql，mysql> \. ~/Documents/db_name.sql和$ mysql -u user -p < ~/Documents/db_name.sql（未指定数据库的情况下）中，可能不会创建数据库，但必须在脚本中创建（请参见上面的脚本）。在$ mysql -u user -p movie-buff < ~/Documents/db_name.sql的情况下，必须先创建数据库。

你在做这一切之前创建了数据库吗？也许那就是我的问题所在？我创建了一个空的数据库，然后尝试从文件中填充它。 - vampiire
