Is it possible, lets say in a database that holds username/password to search for an existing username?

Also how cuold I identify the different records for analysis?


Many Thanks

Why do select all fields ??

Just do like

$query = "select count(username) from TABLENAME where username = '$username' ";

$result = mysql_query($query) or die(mysql_error());
if(mysql_num_rows() > 0 )
   print "User found.";
else
   print "Not found.";

Also beware that this search on username is CASE INSENSITIVE. That is if you search for 'abc' it would even get ABC, aBC,Abc and so on.
