Question

我正在使用与codeigniter的Postgresql数据库连接。我是postgresql的新手。该网站打开。但我无法登录或从数据库中获取任何值。

我将上传配置文件的代码以及database.php文件。的的config.php

// Keep as it is for same if MySQL server is running on same server
define("DBHOSTNAME",'ip_address');

// Add your database name here
define("DBNAME",'db_name'); // Here the database name is 'dummy_myecommerce'

// Add your database user name here
define("DBUSER",'username');  // Here the username is 'dummy_website'

// Add your database password here
define("DBPWD",'password');

现在我将上传 database.php 文件：

$db['default']['hostname'] = 'ip_address';
$db['default']['username'] = 'username';
$db['default']['password'] = 'password';
$db['default']['database'] = 'db_name';
$db['default']['dbdriver'] = 'postgre';
$db['default']['dbprefix'] = 'pre_';
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = FALSE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = '';
$db['default']['char_set'] = 'utf8';
$db['default']['dbcollat'] = 'utf8_general_ci';
$db['default']['swap_pre'] = '';
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;
$db['default']['port'] = 5432;

如果还有其他要求，请告诉我。感谢

Answer 1

某些数据库驱动程序（如PDO，PostgreSQL，Oracle，ODBC）可能需要提供完整的DSN字符串。如果是这种情况，您应该使用'dsn'配置设置，就好像您正在使用驱动程序的底层本机PHP扩展，如下所示：

// PDO $ db [＆＃39;默认＆＃39;] [＆＃39; dsn＆＃39;] =＆＃39; pgsql：host = localhost; port = 5432; dbname = database_name＆＃39 ;;

Try this as well

$db['default']['hostname'] = 'pgsql:host=localhost;dbname=yourdb'; //set host
$db['default']['username'] = 'your username'; //set username
$db['default']['password'] = 'your password'; //set password
$db['default']['database'] = 'your database'; //set databse
$db['default']['dbdriver'] = 'pdo'; //set driver here
