Question

我想问一下，如果数据库中包含“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，如魅力。

$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;

我试图以多种方式使用，但仍然没有工作，任何人都可以提供帮助？感谢。

Answer 1

数据库名称，表名称或字段名称中不允许有空格，因此以下代码将永远不会起作用，因为它超过了规则。

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

应该是这样的，

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

这适用于我：更改system \ database \ drivers \ 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;
}

原件：

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);
}
