cmd>sqlplus / as sysdba;
SQL>shutdown immediate
SQL>alter database archivelog;
SQL>conn squirrel/squirrel;
SQL>CREATE TABLE a(id number(10) not null primary key, name varchar2(20));
SQL>INSERT INTO a(id,name) values(1,zhangsan);
SQL>conn / as sysdba;
SQL> select * from squirrel.a;
ID NAME
---------- --------------------
1 zhangsan
设置时间格式
SQL>alter session set nls_date_format=’yyyy-mm-dd hh24:mi:ss’;
SQL>select sysdate from dual;
SYSDATE
-------------------
2012-03-01 16:00:42
SQL>shutdown immediate;
SQL>startup mount;
SQL>exit
cmd>rman target /
RMAN>backup database;
RMAN>exit;
这里模拟对T表的误删除(DDL类型的TRUNCATE方法)
SQL>truncate table squirrel.a;
接着我们不完全恢复到指定时间2012-03-01 16:00:42
【重要提醒】在使用RMAN完成基于时间点的不完全恢复之前,最好对现场做一个备份,我们这里只需要备份数据库的控制文件和日志文件即可。当恢复结束后不满足我们要求时,可以恢复控制文件和日志文件后重新进行恢复。
RMAN> run {
2> allocate channel c1 type disk;
3> allocate channel c2 type disk;
4> sql 'alter session set nls_date_format="yyyy-mm-dd hh24:mi:ss"';
5> set until time='2012-03-01 16:00:42';
6> restore database;
7> recover database;
8> alter database open resetlogs;}
使用目标数据库控制文件替代恢复目录
分配的通道: c1
通道 c1: sid=156 devtype=DISK
分配的通道: c2
通道 c2: sid=155 devtype=DISK
sql 语句: alter session set nls_date_format="yyyy-mm-dd hh24:mi:ss"
正在执行命令: SET until clause

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.
