Question

我需要在同一个应用程序中连接到MySQL和SQL Server。我的php版本5.6.11和codeigniter 3.0.1。我在下面建立连接的步骤：

我下载此文件并粘贴到xampp \ php \ ext

php_sqlsrv_56_ts
的 php_pdo_sqlsrv_56_ts
像这样编辑php.ini文件：

延长= php_sqlsrv_56_ts.dll
的延长= php_pdo_sqlsrv_56_ts.dll

database.php中

$active_group = 'default';
$query_builder = TRUE;

$db['default'] = array(
    'dsn'   => '',
    'hostname' => 'localhost',
    'username' => 'root',
    'password' => '',
    'database' => 'vtp',
    'dbdriver' => 'mysqli',
    'dbprefix' => '',
    'pconnect' => FALSE,
    'db_debug' => (ENVIRONMENT !== 'production'),
    'cache_on' => FALSE,
    'cachedir' => '',
    'char_set' => 'utf8',
    'dbcollat' => 'utf8_general_ci',
    'swap_pre' => '',
    'encrypt' => FALSE,
    'compress' => FALSE,
    'stricton' => FALSE,
    'failover' => array(),
    'save_queries' => TRUE
);

$db['biodb'] = array(
    'hostname' => '192.168.20.231',
    'username' => 'abzalali',
    'password' => '',
    'database' => 'pdata',
    'dbdriver' => 'sqlsrv',
    'dbprefix' => '',
    'pconnect' => FALSE,
    'db_debug' => TRUE,
    'cache_on' => FALSE,
    'autoinit' => TRUE,
    'stricton' => FALSE,
);

控制器：

<?php

if (!defined('BASEPATH'))
    exit('No direct script access allowed');

class biodb extends CI_Controller {

    public function __construct() {

        parent::__construct();
        $this->sqlsrvr = $this->load->database('biodb', true);
    }

    public function index() {
        $query = $biodb->get('arb_protest_pp');
        foreach ($query->result() as $row)
            echo $row->id;
    }

}

然后我在url中调用控制器'biodb'，并收到错误：

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 65488 bytes) in C:\xampp\htdocs\vtp\system\database\DB_driver.php on line 771

之后：我在此函数

$this->db_select();

public function simple_query($sql)
{
    if ( ! $this->conn_id)
    {
        $this->initialize();
    }
    $this->db_select();
    return $this->_execute($sql);
}

然后我又得到了另一个错误：

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 65488 bytes) in C:\xampp\htdocs\vtp\system\database\DB_driver.php on line 642

我真的没有发现我错过了什么。我需要使用codeigniter活动记录这个sqlserver db。

过去我使用带有CodeIgniter的直接sqlsrv驱动程序遇到了很多问题。

我会通过在databbase.php配置文件中执行以下操作将sqlsrv转换为pdo_sql_srv：

$db['biodb'] = array(
    'hostname' => '192.168.20.231',
    'username' => 'abzalali',
    'password' => '',
    'database' => 'pdata',
    'dbdriver' => 'pdo',
    'subdriver' => 'sqlsrv',
    'dbprefix' => '',
    'pconnect' => FALSE,
    'db_debug' => TRUE,
    'cache_on' => FALSE,
    'autoinit' => TRUE,
    'stricton' => FALSE,
);

我也很惊讶你在控制器中的索引方法上没有得到未定义的var错误。尝试将其更改为：

public function index() {
    //you need to call the database property you 
    //created in your construct which appears to be sqlsrvr
    $query = $this->sqlsrvr->get('arb_protest_pp');
    foreach ($query->result() as $row) {
        echo $row->id;
    }
}
