A not-null constraint simply specifies that a column must not assume the null value. A not-null constraint is always written as a column constraint.

|
|
The following definition uses a notnull constraint for column 'name'. This means that the specified column doesn't accept
|
|
null values.

|
|
<code type='php'>
|
|
class User extends Doctrine_Record
|
|
{
|
|
public function setTableDefinition()
|
|
{
|
|
$this->hasColumn('name', 'string', 200, array('notnull' => true,
|
|
'primary' => true));
|
|
}
|
|
}
