mysql的基础知识

一、存储引擎

mysql> show engines;
+--------------------+---------+----------------------------------------------------------------+--------------+------+------------+
| Engine             | Support | Comment                                                        | Transactions | XA   | Savepoints |

| MEMORY             | YES     | Hash based, stored in memory, useful for temporary tables      | NO           | NO   | NO         |

二、导入数据库脚本

　　在cmd命令行直接导入

C:\Users\plan-B>mysql -uroot -p1234 --p3306 < D:\mysqlscript\sampledb.sql

　　用source命令导入

mysql> source  D:\mysqlscript\sampledb.sql

 三、远程访问权限及用户设置

 grant all privileges on roger.* to roger@'192.168.20.%' identified by "12345a";
 flush privileges;
