方法一简单的
--创建一个磁盘
exec master..xp_cmdshell
'net use z: \\10.10.10.102\d$ "123.com" /user:10.10.10.102\administrator'
--删除影射磁盘
exec master..xp_cmdshell 'net use z: /delete'
--备份数据库
backup database TsingCloudDb to disk='z:\TsingCloudDb.bak'
--自动执行
数据库--SQL server代理--作业 创建新作业---相关操作 时间关系不一一累述
--新建计划--把 exec master..xp_cmdshell 'net use z: /delete' 复制进去可以按照你的计划的时间执行了
------------------------------------------------------------------一下复制别人的 有空再修改-------------------------------------------------------------------------
--备份环境:把数据库服务器(192.168.1.8)的数据库(TEST)备份到(192.168.1.145)的C$下
--首先,做一个与客户端的映射
exec master..xp_cmdshell
'net use z: \\192.168.1.145\c$ "密码" /user:192.168.1.145\administrator'
/*--说明:
z: 是映射网络路径对应本机的盘符,与下面的备份对应
\\192.168.1.145\c$ 是要映射的网络路径
192.168.1.145\administrator
192.168.1.145是远程的计算机名,administrator是登陆的用户名
密码 上面指定的administrator用户的密码
--*/
--其次,进行数据库备份
backup database TEST to disk='z:\Test.bak'
--最后.备份完成后删除映射
exec master..xp_cmdshell 'net use z: /delete'
--以下代码放在作业里做调度,自动备份、自动删除4天前备份
--创建映射
exec master..xp_cmdshell 'net use w: \DatabaseBackup$ "password"/user:Roy',NO_OUTPUT

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.

The best tools and technologies for automating the creation of users in MySQL include: 1. MySQLWorkbench, suitable for small to medium-sized environments, easy to use but high resource consumption; 2. Ansible, suitable for multi-server environments, simple but steep learning curve; 3. Custom Python scripts, flexible but need to ensure script security; 4. Puppet and Chef, suitable for large-scale environments, complex but scalable. Scale, learning curve and integration needs should be considered when choosing.
