如何从SQL查询中获取列的属性（PHP \ Phalcon \ PostgreSQL）

I have two tables: manager, order.

One manager has many orders.

How i can get columns types, which in SELECT, from query like this

SELECT m.name, o.date, o.phone
FROM manager m
LEFT JOIN order o ON m.id = o.manager_id

Postgresql 9.4

SELECT column_name , data_type ,character_maximum_length  FROM information_schema.columns WHERE table_schema = 'your_schema' AND table_name   = 'your_table';

From Phalcon you can use Model metadata.

$manager = new Manager();
$order = new Order();

$metadata = $model->getModelsMetaData();

var_dump($metadata->getDataTypes($manager));

You will get and array with each column name and the type as an integer.

array (size=3)
  'col1' => int 0
  'col2' => int 2
  ...
  'coln' => int 2

The integer is one of the TYPE_* constants from \Phalcon\Db\Column.
