Answer 1

try like this ,
'db'=>array(
'connectionString' => 'mysql:host=localhost;dbname=sarish',
'class'=>'CDbConnection',
'emulatePrepare' => true,
'username' => 'sarish',
'password' => 's#r15h',
'charset' => 'utf8',
'tablePrefix' => '',
),

Answer 2

Try to change the localhost to your IP address 127.0.0.1 and add the the port number, and see what happens.
'connectionString' => 'mysql:host=127.0.0.1;port=3306;dbname=sarish',

Answer 3

I got this problem too,that's my solution here, i guess your double config DB connection, mysql error:using password:NO means your password is empty.... so take a look at /Common/config/main-local.php , there is a pre-config for db connection,so you no need to config db connection at any other config file.....my english is bad,but i hode you can understand me...
