How to correctly set the column default value?

Question

Doctrine ORM

@ORM\Column(name="price",  type="decimal", precision=7, scale=2, options={"default" : 0})
// или
 /**
     * @var int
     *
     * @Column(name="price",  type="decimal",   precision=7, scale=2)
     */
    private $price= 0;

Same for nullable, datetime, text, string values.

Answer 1

The second option (or even better is to set the value in the constructor).
The fact is that not all database vendors support the DEFAULT integrity constraint, so such options are placed in the options attribute .
