如何将远程服务器MYSQL数据库导出导入

Posted 2023-04-12

参考技术A mysql数据库导出第一种利用空间商提供的phpMYADMIN管理工具导出,这种较为简单,大家查一下资料这里就不多讲了.第二种利用MYSQL安装时自带的mysqldump管理工具导出:1)左下角开始菜单-运行-CMD进入DOS命令行状态2)输入:CD D:/Program Files/MySQL/MySQL Server 5.0/binD:/Program Files/MySQL/MySQL Server 5.0/bin为你安装的MYSQL安装目录,/bin为mysqldump管理工具所有在的目录;3)导出语法为:mysqldump -h[hosname] -u[user_name] -p[password] --default-character-set=[char_set_name] [db_name] [save_path]例:然后输入:mysqldump -h119.12.12.11 -umysql-pmysql123--default-character-set=utf8 aspchina --skip-lock-tables d:/aspchina_net.sql119.12.12.11为远程服务器IP,-umysql mysql为数据库用户名,-pmysql123 mysql123 为用户密码,set=utf8为导出MYSQL的编码格式,aspchina为要导出的数据库名,d:/aspchina_net.sql 为导入到你本地的存放路径,aspchina_net.sql你可以自由命名!MYSQL数据库导入如果MYSQL数据库小于2MB可以用mysqldump管理工具导入,如果大小2MB就不行了,因为空间商提供的PHPMYADMIN管理工具一般只能导入小于2MB的数据,这令一些使用MYSQL数据库的站长郁闷了!1)左下角开始菜单-运行-CMD进入DOS命令行状态2)D:/Program Files/MySQL/MySQL Server 5.0/bin为你安装的MYSQL安装目录,/bin为mysqldump管理工具所有在的目录;3)然后输入:mysql -h119.12.12.11 -uaspchina -paspchina123456 aspchina< d:/aspchina_net.sql注释:aspchina_net.sql,如果用户没有创建数据库的权限将不能导入aspchina_net.sql数据库,否则spchina_net.sql只能是多张表不然会出错,这点切记!

尝试使用此脚本，它允许您导入数据。您必须指定表名并在您的 MySQL 服务器上运行生成的代码。

DDL：

CREATE TABLE Labour.Employee 
(
      EmployeeID INT IDENTITY (1, 1) PRIMARY KEY NOT NULL
    , IsMainWorkPlace BIT NOT NULL
    , TabelNumber VARCHAR(6) NULL
    , PersonID INT NOT NULL
    , DepartmentUID UNIQUEIDENTIFIER NOT NULL
    , DateIn DATETIME NOT NULL
    , DateOut DATETIME NULL
    , PositionID INT NULL
    , DatePension DATETIME NULL
    , IsLabourUnionMember BIT NOT NULL
    , FiringReasonID INT NULL
)

查询：

DECLARE

你可以使用Data Loader来做到这一点
