php - 错误文本 :Unknown column ' ' in field list

Question

我无法弄清楚下面的代码行有什么问题，因为我在 php 服务器中收到以下错误:

查询“INSERT INTO Polygon (name, polygons) VALUES (population_data_per_block.1, GeomFromText(@g))”时发生错误错误文本:未知“字段列表”中的“population_data_per_block.1”列

return array ($query , 'INSERT INTO ' . polygon . ' (`name`, `polygons`) VALUES (' . $polygon["name"] . ', GeomFromText(@g))');

Answer 1

我正在使用 php pdo。

    $stmt = $db->prepare('INSERT INTO polygon (name, polygons) VALUES (:name, :polygons)') ;
            $stmt->execute(array(
                ':name' => $polygon["name"],
                ':polygons' => 'GeomFromText(@g)' //i don't know what is GeomFromText(@g)

            ));
