If you want to give a specific user access from all machines in a given domain (for example, mydomain.com), you can issue a GRANT statement that uses the ‘%' wildcard character in the host part of the account name:
译文：如果需要让特定的用户从给定域(例如mydomain.com)的所有计算机*问 MySQL 服务器，你可以执行在账户名的 host 部分使用了通配符“%” 的 GRANT 语句
mysql> GRANT ...
-> ON *.*
-> TO 'myname'@'%.mydomain.com'
-> IDENTIFIED BY 'mypass';
To do the same thing by modifying the grant tables directly, do this:
译文：也可以使用直接修改授权表的方式来实现：
mysql> INSERT INTO user (Host,User,Password,...)
-> VALUES('%.mydomain.com','myname',PASSWORD('mypass'),...);
mysql> FLUSH PRIVILEGES;
再来解决问题:
一、允许用户 wp 从 192.168.2.98 登录 MySQL 服务器(下面的实例均为登录服务器192.168.2.28)
(1)先在MySQL中授权：grant select,update,insert,delete on mysql.* to 'wp'@'192.168.2.98' identified by '123';
(2)再用VFP连接：SQLSTRINGCONNECT("driver={mysql odbc 3.51 driver};server=192.168.2.28;uid=wp;pwd=123;port=3306;")
如果有多个网址，分别执行授权就可以了。
二、允许用户 wp 从某个网段登录 MySQL 服务器
(1)先在MySQL中授权：grant select,update,insert,delete on mysql.* to 'wp'@'192.168.2.%' identified by '123';
(2)再用VFP连接：SQLSTRINGCONNECT("driver={mysql odbc 3.51 driver};server=192.168.2.28;uid=wp;pwd=123;port=3306;")
三、允许用户 wp 从任何网址登录 MySQL 服务器
(1)先在MySQL中授权：grant select,update,insert,delete on mysql.* to 'wp'@'%' identified by '123';
(2)再用VFP连接：SQLSTRINGCONNECT("driver={mysql odbc 3.51 driver};server=192.168.2.28;uid=wp;pwd=123;port=3306;")
