一、存储引擎

mysql> show engines;+--------------------+---------+----------------------------------------------------------------+--------------+------+------------+| Engine             | Support | Comment                                                        | Transactions | XA   | Savepoints |+--------------------+---------+----------------------------------------------------------------+--------------+------+------------+| FEDERATED          | NO      | Federated MySQL storage engine                                 | NULL         | NULL | NULL       || MRG_MYISAM         | YES     | Collection of identical MyISAM tables                          | NO           | NO   | NO         || MyISAM             | DEFAULT | MyISAM storage engine                                          | NO           | NO   | NO         || BLACKHOLE          | YES     | /dev/null storage engine (anything you write to it disappears) | NO           | NO   | NO         || CSV                | YES     | CSV storage engine                                             | NO           | NO   | NO         || MEMORY             | YES     | Hash based, stored in memory, useful for temporary tables      | NO           | NO   | NO         || ARCHIVE            | YES     | Archive storage engine                                         | NO           | NO   | NO         || InnoDB             | YES     | Supports transactions, row-level locking, and foreign keys     | YES          | YES  | YES        || PERFORMANCE_SCHEMA | YES     | Performance Schema                                             | NO           | NO   | NO         |+--------------------+---------+----------------------------------------------------------------+--------------+------+------------+9 rows in set (0.00 sec)

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
