本文章来给各位朋友介绍一下关于在mysql中进行表数据与表结构复制语句,方法会有很多种下面我来介绍介绍,有需要了解的朋友可参考。
先来总结复制表与结的方法
一、CREATE TABLE 方法
整表复制: create table 新表 select * from 旧表;
结构复制: 1、create table 新表 select * from 旧表 where 11;
一,复制表结构
方法1:
代码如下 | 复制代码 |
mysql> create table a like users; //复制表结构 mysql> show tables; |
方法2:
代码如下 | 复制代码 |
mysql> create table b select * from users limit 0; //复制表结构 mysql> show tables; |
方法3:
代码如下 | 复制代码 |
mysql> show create table usersG; //显示创表的sql *************************** 1. row *************************** Table: users Create Table: CREATE TABLE `users` ( //改表名 `ID` bigint(20) unsigned NOT NULL AUTO_INCREMENT, `user_name` varchar(60) NOT NULL DEFAULT '', `user_pass` varchar(64) NOT NULL DEFAULT '', PRIMARY KEY (`ID`) ) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8 //改auto_increment 1 row in set (0.00 sec) |
把sql语句copy出来,改一下表名和atuo_increment,然后在执行一下。
二,复制表数据,以及表结构
方法1:
代码如下 | 复制代码 |
mysql> create table c select * from users; //复制表的sql |
方法2:
代码如下 | 复制代码 |
mysql> create table d select user_name,user_pass from users where id=1; Query OK, 1 row affected (0.00 sec) Records: 1 Duplicates: 0 Warnings: 0 |
上面的2种方法,方便,快捷,灵活性强。
2、CREATE TABLE 新表 LIKE 旧表;
二、INSERT INTO 方法
得到建表语句: show create table 旧表;
复制数据到新表:
1、复制旧表的数据到新表(假设两个表结构一样)
INSERT INTO 新表 SELECT * FROM 旧表;
2、复制旧表的数据到新表(假设两个表结构不一样)
INSERT INTO 新表(字段1,字段2,…….) SELECT 字段1,字段2,…… FROM 旧表;
三、CREATE TEMPORARY TABLE创建临时表

How to effectively monitor MySQL performance? Use tools such as mysqladmin, SHOWGLOBALSTATUS, PerconaMonitoring and Management (PMM), and MySQL EnterpriseMonitor. 1. Use mysqladmin to view the number of connections. 2. Use SHOWGLOBALSTATUS to view the query number. 3.PMM provides detailed performance data and graphical interface. 4.MySQLEnterpriseMonitor provides rich monitoring functions and alarm mechanisms.

The difference between MySQL and SQLServer is: 1) MySQL is open source and suitable for web and embedded systems, 2) SQLServer is a commercial product of Microsoft and is suitable for enterprise-level applications. There are significant differences between the two in storage engine, performance optimization and application scenarios. When choosing, you need to consider project size and future scalability.

In enterprise-level application scenarios that require high availability, advanced security and good integration, SQLServer should be chosen instead of MySQL. 1) SQLServer provides enterprise-level features such as high availability and advanced security. 2) It is closely integrated with Microsoft ecosystems such as VisualStudio and PowerBI. 3) SQLServer performs excellent in performance optimization and supports memory-optimized tables and column storage indexes.

A MySQL trigger is an automatically executed stored procedure associated with a table that is used to perform a series of operations when a specific data operation is performed. 1) Trigger definition and function: used for data verification, logging, etc. 2) Working principle: It is divided into BEFORE and AFTER, and supports row-level triggering. 3) Example of use: Can be used to record salary changes or update inventory. 4) Debugging skills: Use SHOWTRIGGERS and SHOWCREATETRIGGER commands. 5) Performance optimization: Avoid complex operations, use indexes, and manage transactions.

The steps to create and manage user accounts in MySQL are as follows: 1. Create a user: Use CREATEUSER'newuser'@'localhost'IDENTIFIEDBY'password'; 2. Assign permissions: Use GRANTSELECT, INSERT, UPDATEONmydatabase.TO'newuser'@'localhost'; 3. Fix permission error: Use REVOKEALLPRIVILEGESONmydatabase.FROM'newuser'@'localhost'; then reassign permissions; 4. Optimization permissions: Use SHOWGRA

MySQL is suitable for rapid development and small and medium-sized applications, while Oracle is suitable for large enterprises and high availability needs. 1) MySQL is open source and easy to use, suitable for web applications and small and medium-sized enterprises. 2) Oracle is powerful and suitable for large enterprises and government agencies. 3) MySQL supports a variety of storage engines, and Oracle provides rich enterprise-level functions.

The disadvantages of MySQL compared to other relational databases include: 1. Performance issues: You may encounter bottlenecks when processing large-scale data, and PostgreSQL performs better in complex queries and big data processing. 2. Scalability: The horizontal scaling ability is not as good as Google Spanner and Amazon Aurora. 3. Functional limitations: Not as good as PostgreSQL and Oracle in advanced functions, some functions require more custom code and maintenance.
