bitsCN.com
一、查询数据库中的存储过程
方法一(查看指定的存储过程内容):
select body from mysql.proc where name='procedure_name';
方法二(查看所有的存储过程):
show procedure status;
二、MySQL的存储过程导出和导入,具体用法为:
1.导出
[root@localhost bin]# mysqldump -uroot -p -hlocalhost -P3306 -n -d -t -R DBName > procedure_name.sql
参数说明:
-n: --no-create-db
-d: --no-data
-t: --no-create-info
-R: --routines Dump stored routines (functions and procedures)
Mysqldump是客户端工具用来备份数据库或在不同数据库之间进行数据迁移。备份内容包含创建活装载表的SQL语句:
主要参数介绍:
1.连接选项
-u,--user=name
-p,--password=name
-h,--host=name
-P,--port=#
2.输出内容选项
--add-drop-database
--add-drop-table
-n;--no-create-db
-d;--no-data
-t;--no-create-info
3.输出格式选项
--compact
-c --complete-insert
-T(指定数据表中的数据备份为单纯的数据文件和建表SQL两个文件)
注意:xx.sql建表文件是以linux的root用户创建,而xx.txt文件则是一linux的mysql用户创建,因此这两个文件的存放路径一定要保证mysql用户有读写创建文件的权限。
--fields-terminated-by=name(域分隔符)
--fields-enclosed-by=name(域引用符)
--fields-optionally-enclosed-by=name(域引用可选字符)
--fields-escaped-by=name(转义字符)
4.字符集选项
--default--character-set=xx
5.其他选项
-F --flush-logs(备份前刷新日志)
-l --lock-tables(给所有的表加读锁)
2.导入
mysql -hhostname -uusername - ppassword databasename

This website reported on March 7 that Dr. Zhou Yuefeng, President of Huawei's Data Storage Product Line, recently attended the MWC2024 conference and specifically demonstrated the new generation OceanStorArctic magnetoelectric storage solution designed for warm data (WarmData) and cold data (ColdData). Zhou Yuefeng, President of Huawei's data storage product line, released a series of innovative solutions. Image source: Huawei's official press release attached to this site is as follows: The cost of this solution is 20% lower than that of magnetic tape, and its power consumption is 90% lower than that of hard disks. According to foreign technology media blocksandfiles, a Huawei spokesperson also revealed information about the magnetoelectric storage solution: Huawei's magnetoelectronic disk (MED) is a major innovation in magnetic storage media.

Vue3+TS+Vite development tips: How to encrypt and store data. With the rapid development of Internet technology, data security and privacy protection are becoming more and more important. In the Vue3+TS+Vite development environment, how to encrypt and store data is a problem that every developer needs to face. This article will introduce some common data encryption and storage techniques to help developers improve application security and user experience. 1. Data Encryption Front-end Data Encryption Front-end encryption is an important part of protecting data security. Commonly used

What is cache? A cache (pronounced ka·shay) is a specialized, high-speed hardware or software component used to store frequently requested data and instructions, which in turn can be used to load websites, applications, services, and other aspects of the system faster part. Caching makes the most frequently accessed data readily available. Cache files are not the same as cache memory. Cache files refer to frequently needed files such as PNGs, icons, logos, shaders, etc., which may be required by multiple programs. These files are stored in your physical drive space and are usually hidden. Cache memory, on the other hand, is a type of memory that is faster than main memory and/or RAM. It greatly reduces data access time since it is closer to the CPU and faster compared to RAM

Git is a fast, reliable, and adaptable distributed version control system. It is designed to support distributed, non-linear workflows, making it ideal for software development teams of all sizes. Each Git working directory is an independent repository with a complete history of all changes and the ability to track versions even without network access or a central server. GitHub is a Git repository hosted on the cloud that provides all the features of distributed revision control. GitHub is a Git repository hosted on the cloud. Unlike Git which is a CLI tool, GitHub has a web-based graphical user interface. It is used for version control, which involves collaborating with other developers and tracking changes to scripts and

How to correctly use sessionStorage to store sensitive information requires specific code examples. Whether in web development or mobile application development, we often need to store and process sensitive information, such as user login credentials, ID numbers, etc. In front-end development, using sessionStorage is a common storage solution. However, since sessionStorage is browser-based storage, some security issues need to be paid attention to to ensure that the stored sensitive information is not maliciously accessed and used.

How do PHP and swoole achieve efficient data caching and storage? Overview: In web application development, data caching and storage are a very important part.

For students who are familiar with database operations, writing beautiful SQL statements and finding ways to find the data they need from the database is a routine operation. For students who are familiar with machine learning, it is also a routine operation to obtain data, preprocess the data, build a model, determine the training set and test set, and use the trained model to make a series of predictions about the future. So, can we combine the two technologies? We see that data is stored in the database, and predictions need to be based on past data. If we query future data through the existing data in the database, then it is

Overview of Java Collection Framework The Java collection framework is an important part of the Java programming language. It provides a series of container class libraries that can store and manage data. These container class libraries have different data structures to meet the data storage and processing needs in different scenarios. The advantage of the collection framework is that it provides a unified interface, allowing developers to operate different container class libraries in the same way, thereby reducing the difficulty of development. Data structures of the Java collection framework The Java collection framework contains a variety of data structures, each of which has its own unique characteristics and applicable scenarios. The following are several common Java collection framework data structures: 1. List: List is an ordered collection that allows elements to be repeated. Li
