我已经在数据库中做了这个。hp:
/* user */
$active_group = "user";
$active_record = TRUE;
$db['user']['hostname'] = "jkt";
$db['user']['username'] = "calculation";
$db['user']['password'] = "C4lculation";
$db['user']['database'] = "MedsLi";
$db['user']['dbdriver'] = "sqlsrv";
$db['user']['dbprefix'] = "";
$db['user']['pconnect'] = TRUE;
$db['user']['db_debug'] = TRUE;
$db['user']['cache_on'] = FALSE;
$db['user']['cachedir'] = "";
$db['user']['char_set'] = "utf8";
$db['user']['dbcollat'] = "utf8_general_ci";
$active_group = "default";
$active_record = TRUE;
$db['default']['hostname'] = "localhost";
$db['default']['username'] = "root";
$db['default']['password'] = "";
$db['default']['database'] = "maindatabase";
$db['default']['dbdriver'] = "mysql";
$db['default']['dbprefix'] = "";
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = "";
$db['default']['char_set'] = "utf8";
$db['default']['dbcollat'] = "utf8_general_ci";
<br/>'
但是$db['user']['hostname']="jkt"中的列和表；仍然无法连接。默认为数据库管理（mysql）；user代表用户可以访问的数据库（sqlserver）
错误：
A PHP Error was encountered
Severity: Notice
Message: Undefined property: stdClass::$Comp_Name
Filename: views/HCM_user_view.php
Line Number: 36
请提供帮助
这是型号：
$this->db->select('*');
$this->db->limit(100);
$this->db->from('cm');
$query = $this->db->get();
$myRow = $query->row();
return $query;
查看错误：
foreach($allHCM->result() as $row)
php echo $row->trans_ref
php echo $row->Cert_No
php echo $row->Comp_Name
php echo $row->status_code
必须在一个数据库中设置pconnect true，而不是在两个数据库中。。。
而且。。。尝试使用此代码进行多重连接。。。
$DB1 = $this->load->database('default', TRUE);
$DB2 = $this->load->database('user', TRUE);
使用。。。。
$DB1->get('tablename');
或者。。。
$DB2->get('tblname');
不是。。。。
$this->db->get('tablename'); // if you use this, this will load the default database....
如果我能很好地理解你，你应该使用
$db['default']['dbdriver'] = 'sqlsrv';
要连接到sqlserver，请看这里的问题
CodeIgniter MSSQL连接
