This is exactly what the php function below will do:
( just change the myemail@server.com to your email address )

function ewd_email_sql($sSql){  $my_email = "myemail@server.com";//set your email address

  $my_subject = "SQL Query Email";//email subject

  $my_message = !empty($sSql) ? $sSql : "SQL Query was empty";

  $my_ip = ""; //enter your IP ADDRESS to make sure you only send the email when you view this page

$mime_boundary = "<<<--==+X[".md5(time())."]\r\n\r\n";// Generate a boundary string

  $headers = "From:".$my_email."\r\n".

                "To:".$my_email."\r\n".

                 "MIME-Version: 1.0\r\n" .

                 "Content-Type: text/plain;\r\n".

                 "boundary=\"".$mime_boundary."\"\r\n";

  if(!empty($my_ip) && $_SERVER['REMOTE_ADDRESS'] == $my_ip){

    mail($my_email,$my_subject,$my_message,$headers);

  }

  return;

}

//usage e.g

$sSql = "SELECT * FROM table_name WHERE something='".addslashes("something_else")."'";

  //email it

  ewd_email_sql($sSql);//call function

..............

//rest of the code below

Hope it helps…
