Yii 1.1: Getting nulls from database instead of empty strings

10 followers

To get null from database instead of empty strings you need to set up your DB connection as follows:

'db'=>array(
  'connectionString' => 'mysql:host=localhost;dbname=test',
  'username' => 'root',
  'password' => '',
  'charset' => 'utf8',
 
  // here it is:
  'nullConversion' => PDO::NULL_EMPTY_STRING,
),

it actually works in the opposite direction

I tried it with PDO_MYSQL driver and it seems that the conversion occurs on read operations and not on save, which can make a significant difference in some circumstances (e.g. nullable temporal columns, queries using IS NULL).
