|
34
|
|
|
* |
|
35
|
|
|
* ```php |
|
36
|
|
|
* $dsn = new Dsn('sqlsrv', 'localhost', 'yiitest', '1433'); |
|
37
|
|
|
* $db = new ConnectionPDO(new PDODriver($dsn->asString(), 'username', 'password'), $queryCache, $schemaCache); |
|
38
|
|
|
* ``` |
|
39
|
|
|
* |
|
40
|
|
|
* Will result in the DSN string `sqlsrv:Server=localhost,1433;Database=yiitest`. |
