PDO PHP ORACLE connection

Question

heres my code

$database = ' 
    (DESCRIPTION = 
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.8.28)(PORT = 1521))
      )
    (CONNECT_DATA =
      (SERVICE_NAME = orcl)
    )
   )';


    $db = new PDO('oci:dbname='.$database, 'middleuser', '1');


    $sth = $db->prepare('SELECT * from BD_CENTERDEPT');
    $sth->execute();

    while($row = $sth->fetch(PDO::FETCH_OBJ)) {  

        echo $row->NAME."\n";  

    }

no error shown, but why? i am using oracle instant client. i already created a path in environmental variables "C:\\xampp\\instantclient_12_1"

and already uncomment "extension=php_pdo_oci.dll" in my php.ini iam pretty sure that

BD_CENTERDEPT has NAME column and data on it.

no errors but no data shown? how do I know if I really connected to oracle database?

Answer 1

是的，我忘记了查询中的数据库名称:)必须是

$db->prepare('SELECT * from dbname.BD_CENTERDEPT')
