Question

为什么此数据库查询失败？在我的CentOS中。

错误/例外：

"Notice: Undefined variable: table in /var/www/html/-manager/application/controllers/IndexController.php on line 37 Fatal error: Call to a member function getAdapter() on a non-object in /var/www/html/-manager/application/controllers/IndexController.php on line 37 Warning: Unknown: write failed: No space left on device (28) in Unknown on line 0 Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/var/lib/php/session) in Unknown on line 0

磁盘空间？：

$ df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg_demo-lv_root
                       50G   47G     0 100% /

                      170G  200M  161G   1% /home

呼叫：

    $rows = new Application_Model_Clients();  // PASS
    $dbsession = $rows->give_sessions("test"); // FAILS

库存为：

mysql> select username,password from sh_operator;
+----------+----------+
| username | password |
+----------+----------+
| test     | 1234567  |
+----------+----------+
1 rows in set (0.00 sec)

mysql> 


<?php

class Application_Model_Clients extends Zend_Db_Table {

  protected $_name = 'web145-mydb.sh_operator';

  public function addRecord($post) {
    $encrypted = mt_rand();
    $value = array(
        'email'       => $post->email,
    );
    return $this->insert($value);
  }

  public function search($zip) {
    $result = $this->fetchRow("zip =" . $zip);
    return $result->toArray();
  }

  public function give_sessions($input) {
    Zend_Debug::dump($input); // PASS test
    echo "alive 0 "; // PASS
    $result = $this->fetchRow("username ='" . $input . "'");
    echo "alive 1 "; // fails
    exit;
    return $result->toArray();
  }

}

?>

Answer 1

看起来你的give_sessions()的sql很可能会以多个引号"username ='" . "test" . "'"结束。

您可以考虑让自己轻松一点，只需使用提供的select()对象语法来处理引用。如果你不这样做，fetchRow()只会select()。

public function give_sessions($input) {
    $select = $this->select();
    $select->where('username = ?', $input);
    $result = $this->fetchRow($select);
    return $result->toArray();
  }

使用select（）还可以在构建查询时提供很大的灵活性。

您可能希望使用控制器操作中的某些代码测试当前的适配器配置，例如：

$table = new Application_Model_Clients();
Zend_Debug::dump($table->getAdapter()->listTables(), 'Adapter Table List');

将回显出适配器可以访问的表的数组。

Answer 2

对于带有“ - ”的数据库名称，您可能需要使用反引号将其正确分配给适配器。

   protected $_name = '`web145-mydb`.sh_operator';

该异常表明您没有剩余磁盘空间。清理一些应该解决问题的空间。
