无法在PDO中进行PG连接

Question

I am unable to connect to my database. Sure I'm just missing something simple:

$host = "localhost";
$port = "5432";
$db_name = 'db';
$username = "user";
$password = "pass";
$dbh = new PDO("pgsql:dbname=$db_name; host=$host", $username, $password );

$dbh->setAttribute( PDO::ATTR_ERRMODE , PDO::ERRMODE_EXCEPTION );

$sth = $dbh->prepare("
    SELECT *
    FROM   test1
    WHERE  id = :id
    ");

$sth->bindValue(':id', 1, PDO::PARAM_STR);
$sth->execute();

$result = $sth->fetchAll(PDO::FETCH_ASSOC);
var_dump($result);

I get the error

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42P01]: Undefined table: 7 ERROR: relation "test1" does not exist LINE 3: FROM test1 ^' in ...[url]... address Stack trace: #0 ...[url]... PDOStatement->execute() #1 {main} thrown in ...[url]

Thanks!

Maybe try this:

$host = 'localhost';
$port = '5432';
$db_name = 'db';
$username = 'user';
$password = 'pass';

$dbh = new PDO('pgsql:port=' . $port . ';host=' . $host . ';dbname=' . $db_name . ';charset=utf8', '' . $username . '', '' . $password . '');

1. try using this DSN Format: "pgsql:host=localhost;port=5432;dbname=db;user=user;password=pass".
2. check that your user has all the privileges it needs on postgresql to access the schema, DB and that table. "grant select on table test1 TO user" should give you access for that table.
