为什么无法建立连接!!如何在不同服务器上的两个数据库中的两个表之间创建关系以获取信息实际上,我想从第二个服务器中的一个表中获取记录并插入到该表中的另一个服务器表选择是正确的:site1.com.class.users
这是我的代码:
$conn_server1=mysql_connect("site1.com","user","pass");
$db_server1=mysql_select_db("class",$conn_server1);
$conn_server2=mysql_connect("site2.com","user","pass");
$db_server2=mysql_select_db("class",$conn_server2);
$result=mysql_query("select * from site2.com.class.users where site2.com.class.users.mobile not in(select mobile form site1.com.class.users)",$conn_server1);
while(mysql_fetch_assoc($result))
mysql_query("insert into site1.com.class.users(name,family,phone1,phone2,mobile) select name,family,phone1,phone2,mobile from
site2.com.class.users",$conn_server1);
site2.com.class.users",$conn_server1);
