MySQL数据库的“重命名”_MySQL

MySQL 数据库导出的数据被保存在后缀名为 .sql 的文件中。其实这个文件就是文本文件,其中包含了许多条 SQL 语句。当在一个空的数据库上执行完该文本文件中的所有 SQL 语句后,生成的数据库就和之前选择导出的数据一致了。

mysqldump.exe 可以用来导出数据库中的数据,一些图形化界面的 MySQL 管理工具,比如 MySQL Workbench 就是利用它来导出数据的。但是,导出的 sql 文件中仍然了包含了其原先所在的数据库。也就是说,如果导出之前这张表在名为 test 的数据库中,那么导出之后的 sql 文件,再导入到其他服务上时,仍然会创建一个名为 test 的数据库(如果不存在的话)。

很多时候,我们需要改变数据库的名称,比如你在本地架了一个 wordpress 博客,想上传到空间商提供的空间里,但是空间商只提供给你一个给定名称的数据库——或者你就是想改变一下数据库名。这个问题困扰了我一个晚上……后来,我发现,可以用一个很简单的方法解决。

用记事本打开 sql 文件,在顶部有三处原先数据库的名称(包括一处注释,这里是三处 "test")。只要把那三处名称改成你想要的新数据库名称,然后再导入新的环境,就会创建新的数据库了。

这是个典型的新手问题,老手请无视吧。

How does Go language implement the addition, deletion, modification and query operations of the database? How does Go language implement the addition, deletion, modification and query operations of the database? Mar 27, 2024 pm 09:39 PM

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.

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 backend method uses PHP's file_get_contents() function to read the content from the text file and embed it into the HTML page.
