Question

我已尝试从命令行

执行此操作

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

我试过从mysqlimport

做这件事

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

我只使用文件名在正确的目录中尝试了两种方法。

我尝试使用

输入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)

我觉得我错过了什么。根据谷歌搜索和尝试的最后30分钟，这似乎是一个微不足道的操作。

最终我必须在使用正确的数据库时将整个.sql文件复制并粘贴到mysql shell中。

我觉得自己像个穴居人。请帮忙。

Answer 1

我无法重现这个问题：

档案：~/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的：

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：

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

<强>更新

对于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），可能无法创建数据库，但必须在脚本中创建（请参阅上面的脚本）。在$ mysql -u user -p movie-buff < ~/Documents/db_name.sql的情况下，必须在之前创建数据库。

Answer 2

您应该使用mysql命令导入mysqldump sql文件：

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语句的包装器。来自mysqlimport文档：

mysqlimport客户端为LOAD提供命令行界面 DATA INFILE SQL语句。 mysqlimport的大多数选项都对应直接到LOAD DATA INFILE语法的子句。见13.2.6节， “LOAD DATA INFILE语法”。

从mac命令行将.sql文件导入mysql。试过mysql -u root -p db_name＆gt;路径/到/ dbfile.sql
