是否可以“准备”推进1.4标准,以便在回路内有效使用?

推进似乎不支持这个开箱即用。举一个例子, Book 班级。 BookPeer::doSelect() 电话 BookPeer::doSelectStmt() 并将结果传递给 BookPeer::populateObjects() . bookpeer::doselectstmt()。 电话 BasePeer::doSelect() ,它总是调用 BasePeer::createSelectSql() 要创建SQL语句,请准备并将其传递给 BasePeer::populateStmtValues() 实际绑定值。

您可以从这些方法中获取代码以获得类似的结果(无异常或事务处理):

$criteria = new Criteria();
$criteria->addThis();
$criteria->addThat();


$con = Propel::getConnection($criteria->getDbName(), Propel::CONNECTION_READ);
$params = array();
$sql = BasePeer::createSelectSql($criteria, $params);
$stmt = $con->prepare($sql);
// $stmt is a prepared PDOStatement
// $params is an array of the form: [{'table': 'tableName', 'column': 'columnName', 'value': 'paramValue'}, ...]
// You can keep this format and use BasePeer::populateStmtValues(), or you can call $stmt->bindParam() yourself

// Now in the loop, we set the params ourself
foreach ($loop as $loopData) {
    // Bind the params, using your preferred method
    // ...

    // Pass the prepared and bound statement to populateObjects()
    $books = BookPeer::populateObjects($stmt);

    // Do something with the found objects
    // ...
}
