【问题描述】：

我想问，如果数据库包含“空格”字符，为什么 codeigniter 无法连接到数据库，下面是连接工作的示例代码。

$db['posko_db']['hostname'] = 'localhost';
$db['posko_db']['username'] = 'root';
$db['posko_db']['password'] = '';
$db['posko_db']['database'] = 'database';  <---- without spaces
$db['posko_db']['dbdriver'] = 'sqlsrv';
$db['posko_db']['dbprefix'] = '';
$db['posko_db']['pconnect'] = FALSE;
$db['posko_db']['db_debug'] = TRUE;
$db['posko_db']['cache_on'] = FALSE;
$db['posko_db']['cachedir'] = '';
$db['posko_db']['char_set'] = 'utf8';
$db['posko_db']['dbcollat'] = 'utf8_general_ci';
$db['posko_db']['swap_pre'] = '';
$db['posko_db']['autoinit'] = TRUE;
$db['posko_db']['stricton'] = FALSE;

这里是连接无法工作的示例代码

$db['posko_db']['hostname'] = 'localhost';
    $db['posko_db']['username'] = 'root';
    $db['posko_db']['password'] = '';
    $db['posko_db']['database'] = 'data base';  <---- with spaces
    $db['posko_db']['dbdriver'] = 'sqlsrv';
    $db['posko_db']['dbprefix'] = '';
    $db['posko_db']['pconnect'] = FALSE;
    $db['posko_db']['db_debug'] = TRUE;
    $db['posko_db']['cache_on'] = FALSE;
    $db['posko_db']['cachedir'] = '';
    $db['posko_db']['char_set'] = 'utf8';
    $db['posko_db']['dbcollat'] = 'utf8_general_ci';
    $db['posko_db']['swap_pre'] = '';
    $db['posko_db']['autoinit'] = TRUE;
    $db['posko_db']['stricton'] = FALSE;

我尝试了很多方法，但仍然无法正常工作，有人可以帮忙吗？谢谢。

【问题讨论】：

它适用于 MySQL 数据库。
让我试试，等一下。
它适用于 MySQL 即时创建名为“数据库”的数据库并建立连接。
如果是这样请检查\system\database\drivers\sqlsrv\sqlsrv_driver.php，也许你可以解决问题。
也检查一下。 stackoverflow.com/questions/26087730/…

【解决方案1】：

数据库名、表名或字段名中不允许有空格，因此下面的代码将永远无法工作，因为它超出了规则。

 $db['posko_db']['database'] = 'data base';  <---- with spaces -->

应该是这样的，

$db['posko_db']['database'] = 'database';

这对我有用：更改系统\数据库\驱动程序\sqlsrv\sqlsrv_driver.php

function db_connect($pooling = false)
{
    // Check for a UTF-8 charset being passed as CI's default 'utf8'.
    $character_set = (0 === strcasecmp('utf8', $this->char_set)) ? 'UTF-8' : $this->char_set;

    $connection = array(
        'UID'               => empty($this->username) ? '' : $this->username,
        'PWD'               => empty($this->password) ? '' : $this->password,           
        'ConnectionPooling' => $pooling ? 1 : 0,
        'CharacterSet'      => $character_set,
        'ReturnDatesAsStrings' => 1
    );
    // If the username and password are both empty, assume this is a
    // 'Windows Authentication Mode' connection.
    if(empty($connection['UID']) && empty($connection['PWD'])) {
        unset($connection['UID'], $connection['PWD']);
    }
            $conn = sqlsrv_connect($this->hostname, $connection);
            sqlsrv_query($conn,'USE ['.$this->database.']');
    return $conn;
}

原文：

function db_connect($pooling = false)
{
    // Check for a UTF-8 charset being passed as CI's default 'utf8'.
    $character_set = (0 === strcasecmp('utf8', $this->char_set)) ? 'UTF-8' : $this->char_set;

    $connection = array(
        'UID'               => empty($this->username) ? '' : $this->username,
        'PWD'               => empty($this->password) ? '' : $this->password,
        'Database'          => $this->database,
        'ConnectionPooling' => $pooling ? 1 : 0,
        'CharacterSet'      => $character_set,
        'ReturnDatesAsStrings' => 1
    );

    // If the username and password are both empty, assume this is a
    // 'Windows Authentication Mode' connection.
    if(empty($connection['UID']) && empty($connection['PWD'])) {
        unset($connection['UID'], $connection['PWD']);
    }

    return sqlsrv_connect($this->hostname, $connection);
}
