导出所有的数据库
mysqldump -uuserName -ppassword --all-database > D:/all.sql
需要注意的是，该命令需要在MySql的安装目录的bin目录下使用，例如在bin下输入mysqldump，会给出提示信息
C:\Program Files\MySQL\MySQL Server 5.6\bin > mysqldump
Usage: mysqldump [OPTIONS] database [tables]
OR mysqldump [OPTIONS] --databases [OPTIONS] DB1 [DB2 DB3...]
OR mysqldump [OPTIONS] --all-databases [OPTIONS]
For more options, use mysqldump --help
导入所有的数据库
source D:/all.sql
需要注意的是，该命令需要在MySql的命令行窗口中使用（MySql commond line client），例如在命令行中输入source，给出提示信息
mysql> source
ERROR:
Usage: \. <filename> | source <filename>
导出某个数据库
C:\Program Files\MySQL\MySQL Server 5.6\bin>mysqldump -uroot -padmin --databases
mysql mywebsite > D:/mysqlmywebsite.sql
Warning: Using a password on the command line interface can be insecure.
这种方式会将mysql和mywebsite两个数据库导入到一个sql文件中，文件名称为mysqlmywebsite
导入某个数据库
mysql>source D:/mysqlmywebsite.sql 或者在cmd的命令行中指定导入的数据库 C:\Program Files\MySQL\MySQL Server 5.6\bin>mysql -uroot -padmin db1 < D:/db1.sql
导出某些数据表
C:\Program Files\MySQL\MySQL Server 5.6\bin> mysqldump -uusername -ppassword db1 table1 table2 > tb1tb2.sql
导入某些数据表
在系统命令行 mysql -uusername -ppassword db1 < tb1tb2.sql 或MySql命令行 mysql> use db1; mysql> source tb1tb2.sql;
mysqldump字符集设置
mysqldump -uusername -ppassword --default-character-set=UTF8 db1 table1 > tb1.sql
注意在MySql中，用UTF8表示UTF-8编码，比如在MySql命令行中输入show charset;可以查看到MySql所支持的所有字符集
mysql> show charset;
