今天按日期过滤POSTGRE和PHP

Question

目前对postgre和php的新手需要帮助获取当前日期的树木总数

*我只需要在当前日期对当前树进行计数，但似乎无法使其正常工作。

 $sql = "SELECT trees.tree_type, tree_solds.transaction_id, 
                tree_solds.actual_height, tree_solds.selling_height, 
                tree_solds.sub_total,transactions.date_purchased 
         FROM tree_solds
         LEFT JOIN trees on tree_solds.tree_id = trees.id
         LEFT JOIN transactions on transactions.id = tree_solds.transaction_id
         WHERE user_id = 8";

 $res = pg_query($sql);
 $count = pg_num_rows($res);

 echo $count;

我不知道我是否理解这是什么问题，但是因为你说＆＃34;当前日期＆＃34;我猜你刚才错过了过滤日期？

 $sql = "SELECT trees.tree_type, tree_solds.transaction_id, 
            tree_solds.actual_height, tree_solds.selling_height, 
            tree_solds.sub_total,transactions.date_purchased 
     FROM tree_solds
     LEFT JOIN trees on tree_solds.tree_id = trees.id
     LEFT JOIN transactions on transactions.id = tree_solds.transaction_id
     WHERE user_id = 8 AND transactions.date_purchased BETWEEN current_date AND current_date + INTERVAL '1 DAY'";
