mysql常用导出数据命令:
1.mysql导出整个数据库
  mysqldump -hhostname -uusername -ppassword databasename > backupfile.sql  
  mysqldump -hlocalhost -uroot hqgr> hqgr.sql     (如果root用户没用密码可以不写-p,当然导出的sql文件你可以制定一个路径,未指定则存放在mysql的bin目录下)

2.mysql导出数据库一个表
  mysqldump -hhostname -uusername -ppassword database  tablename> 导出的文件名
  mysqldump -hlocalhost -uroot hqgr t_ug_user> user.sql

3.mysql导出一个数据库结构
 mysqldump -hhostname -uusername -ppassword  -d --add-drop-table databasename>d:hqgrstructure.sql
 -d 没有数据 --add-drop-table 在每个create语句之前增加一个drop table

4.如果需要导出mysql里面的函数或者存储过程
  mysqldump -hhostname -uusername -ppassword -ntd -R databasename > backupflie.sql
  mysqldump -hlocalhost -uroot -ntd -R hqgr > hqgr.sql
  其中的 -ntd 是表示导出存储过程;-R是表示导出函数

mysql常用导入数据的命令:
1.mysql命令
  mysql -hhostname -uusername - ppassword databasename 2.source命令
  mysql>source backupfile.sql
