数据库是.frm,.myd,myi备份如何导入mysql
今天找了个案例,琢磨了半天,才分析大概出来,数据库是.frm,.myd,myi备份,不会导入mysql,到网上找了些资料,导入成功。 首先说一下这几种文件是干什么的,*.frm是描述了表的结构,*.MYD保存了表的数据记录,*.MYI则是表的索引 把mysql数据库的*.frm,*.myd
今天找了个案例,琢磨了半天,才分析大概出来,数据库是.frm,.myd,myi备份,不会导入mysql,到网上找了些资料,导入成功。
首先说一下这几种文件是干什么的,*.frm是描述了表的结构,*.MYD保存了表的数据记录,*.MYI则是表的索引
把mysql数据库的*.frm,*.myd,*.myi,文件导到数据的方法
1、最简单就是,直接拷贝到数据库的的data下的数据库文件夹,前提是
mysql的版本一致,字体一致。
此方法简单快捷但不是没个人都能做到。
2、就是在本地机器安装mysql数据库转换*.frm,*.myd,*.myi,文件为*.sql文件:
1、首先安装mysql,最好版本和服务器一致,字体也要一致(不一致导入后有后遗症-乱码)。
2、然后用建库命令 创建新的数据库命令如下:
create database name;(创建名为name的数据库呵呵“;”不能少)然后去你安装的mysql目录下的data文件夹下就有个name文件夹。(为何在此我的Mysql5.5版本,没有生成此文件夹呢?
按照网上的说法,我建立那个名为dbname的数据库时系统就建立了个以数据库名命名的文件夹,这个文件夹位于MySQL安装目录下的data文件夹下,我找了半天根本没有,甚至MySQL安装目录下根本就没有data这个文件夹,再次google,原来是这样,MySQL安装路径下面有个my.ini,用记事本打开 查找 datadir,后面有路径, 我的是C:/ProgramData/MySQL/MySQL Server5.1/Data/
)
3、把你的*.frm,*.myd,*.myi文件统统考P到data文件夹下。
4、然后在命令提示符下进入到mysql 安装目录的bin目录下 进行导出为*.sql文件。
mysqldump -uroot -p name > name.sql。
自己操作的几点体会:
1、mysql数据库最好安装的根目录下这样在命令提示符时省很多事情。
2、*.sql倒出时最好是一个表一个表的导出 文件名最好为 dataname_tabname.sql,好记便于导入。
而且一个表的导出*.sql文件小。因为好多数据库限制大小,例如我用的DH的空间限制为10m,大了的话导入不了(对了导出后大于服务器限制的可以打成zip也可以导入)
如果不能够导入成功 可以联系QQ:472995301

Backing up and restoring a MySQL database in PHP can be achieved by following these steps: Back up the database: Use the mysqldump command to dump the database into a SQL file. Restore database: Use the mysql command to restore the database from SQL files.

Go language is an efficient, concise and easy-to-learn programming language. It is favored by developers because of its advantages in concurrent programming and network programming. In actual development, database operations are an indispensable part. This article will introduce how to use Go language to implement database addition, deletion, modification and query operations. In Go language, we usually use third-party libraries to operate databases, such as commonly used sql packages, gorm, etc. Here we take the sql package as an example to introduce how to implement the addition, deletion, modification and query operations of the database. Assume we are using a MySQL database.

How to use MySQLi to establish a database connection in PHP: Include MySQLi extension (require_once) Create connection function (functionconnect_to_db) Call connection function ($conn=connect_to_db()) Execute query ($result=$conn->query()) Close connection ( $conn->close())

Hibernate polymorphic mapping can map inherited classes to the database and provides the following mapping types: joined-subclass: Create a separate table for the subclass, including all columns of the parent class. table-per-class: Create a separate table for subclasses, containing only subclass-specific columns. union-subclass: similar to joined-subclass, but the parent class table unions all subclass columns.

Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons. The new feature introduces an album called "Recovered" in the Tools section of the Photos app that will automatically appear when a user has pictures or videos on their device that are not part of their photo library. The emergence of the "Recovered" album provides a solution for photos and videos lost due to database corruption, the camera application not saving to the photo library correctly, or a third-party application managing the photo library. Users only need a few simple steps

HTML cannot read the database directly, but it can be achieved through JavaScript and AJAX. The steps include establishing a database connection, sending a query, processing the response, and updating the page. This article provides a practical example of using JavaScript, AJAX and PHP to read data from a MySQL database, showing how to dynamically display query results in an HTML page. This example uses XMLHttpRequest to establish a database connection, send a query and process the response, thereby filling data into page elements and realizing the function of HTML reading the database.

Analysis of the basic principles of the MySQL database management system MySQL is a commonly used relational database management system that uses structured query language (SQL) for data storage and management. This article will introduce the basic principles of the MySQL database management system, including database creation, data table design, data addition, deletion, modification, and other operations, and provide specific code examples. 1. Database Creation In MySQL, you first need to create a database instance to store data. The following code can create a file named "my

PHP is a back-end programming language widely used in website development. It has powerful database operation functions and is often used to interact with databases such as MySQL. However, due to the complexity of Chinese character encoding, problems often arise when dealing with Chinese garbled characters in the database. This article will introduce the skills and practices of PHP in handling Chinese garbled characters in databases, including common causes of garbled characters, solutions and specific code examples. Common reasons for garbled characters are incorrect database character set settings: the correct character set needs to be selected when creating the database, such as utf8 or u
