Question

我正在尝试获取此查询的结果：

// SELECT MIN(`inventory_date`) FROM `tour_cms_inventory` WHERE extra_id = 52

使用以下代码：

$min = TourCmsInventoryQuery::create()
                    ->withColumn('MIN(inventory_date)')
                    ->filterByExtraId($tour->getId())
                    ->groupByExtraId()
                    ->find();

但是我得到这个错误：

Fatal error: Uncaught PDOException: SQLSTATE[42000]: Syntax error or access violation: 1140 In aggregated query without GROUP BY, expression #1 of SELECT list contains nonaggregated column 'mkte_circuitos_imp.tour_cms_inventory.id'; this is incompatible with sql_mode=only_full_group_by in C:\laragon\www\mkte_circuitos\vendor\propel\propel\src\Propel\Runtime\Connection\StatementWrapper.php:194

我想Propel在选择中添加了pk（id）（mkte_circuitos_imp.tour_cms_inventory.id）。

我做错了吗？

最好的问候

编辑我也尝试这样做：

$con = \Propel\Runtime\Propel::getWriteConnection(TourCmsInventoryTableMap::DATABASE_NAME);
            $con->useDebug(true);

            $sql = 'SELECT MIN(inventory_date) FROM tour_cms_inventory WHERE extra_id=:extra_id';

            $stmt = $con->prepare($sql);

            $rs = $stmt->execute([':extra_id'=>$tour->getId()]);

但是...返回true ！！

您需要为聚合函数使用别名，请尝试：

$min = TourCmsInventoryQuery::create()
   ->withColumn('MIN(inventory_date)', 'MinInventoryDate')
   ->filterByExtraId($tour->getId())
   ->groupByExtraId()
   ->find();

如何使用Propel获得MAX和/或MIN Aggregate mysql函数？
