php-错误文本：字段列表中的未知列''

Question

I can't figure out what it is wrong with the below line of code as I'm getting the following error in php server:

Error happened on query "INSERT INTO polygon ( name , polygons ) VALUES (population_data_per_block.1, GeomFromText(@g))" Error text:Unknown column 'population_data_per_block.1' in 'field list'

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

Answer 1

尝试使用命令fetchColumn或fetchAll 。

Answer 2

i am using 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)

            ));
