I have a column with datetime datatype called 'updated\_at' in a mysql table,where i want the current date and time.Im trying to insert a record into the mysql table from php,as follows:

```
mysql_query("INSERT INTO my_table (service_name,service_status,service_comment,user_name,updated_at) VALUES($service_name,$service_status,$service_comment,$user_name,$updated_at) ")

```

$updated\_at is defined as follows:

```
$updated_at = date("D, d M Y H:i:s O");

```

But the insert is not taking place. Any way to fix this problem ?

Please help
Thank You
