주 키로 데이터 찾기

find () 방법을 호출하면 메인 키 값을 사용하여 테이블에서 데이터를 쉽게 검색할 수 있습니다.만약 당신이 어떤 데이터만 조회하고 싶다면, 이 방법은zend 로 되돌아옵니다db_table_row 대상, 여러 개의 기록을 조회하려면zenddb_table_rowset 대상입니다.

<?php
class RoundTable extends Zend_Db_Table {}

$table = new RoundTable();

// SELECT * FROM round_table WHERE id = "1"
$row = $table->find(1);

// SELECT * FROM round_table WHERE id IN("1", "2", 3")
$rowset = $table->find(array(1, 2, 3));
?>
         

"만약 한 데이터만 조회하고 싶다면, 이 방법은zend db table row 대상 오류로 되돌아갈 것입니다. 테스트를 통해 되돌아오는 것도"zend db table rowset 대상 "입니다.
코드:
require_once 'Zend/Db.php';
$params = array(
    'host' => '127.0.0.1',
    'username' => 'root',
    'password' => '',
    'dbname' => 'guestbook'
);
$db = Zend_Db::factory('PDO_MYSQL', $params);
//모든 ZendDb_Table 객체 기본 adapter 설정
require_once 'Zend/Db/Table.php';
Zend_Db_Table::setDefaultAdapter($db);
class Guestbook extends Zend_Db_Table {    
}
$table = new Guestbook();
//SELECT * FROM round_table WHERE id = "1"
$row = $table->find(1);
var_dump($row);
//SELECT * FROM round_table WHERE id IN("1", "2", 3")
$rowset = $table->find(array(1, 2, 3));
var_dump($rowset);
?>
결과:
