I would look as follows with a die statement: 

do {
   local *STDERR = *STDOUT;
   $! = 0;
   die(h1( {class=>'cyan'}, "Error occured $row->{username}! Script ha
+ve to die" ));
} if $select->rows;

Of course, the following would be shorter: 

do {
   print(h1( {class=>'cyan'}, "Error occured $row->{username}! Script 
+have to die" ));
   exit(0);
} if $select->rows;

Even shorter: 

print(h1( {class=>'cyan'}, "Error occured $row->{username}! Script hav
+e to die" )), exit(0)
   if $select->rows;

The problem is neither is particularly readable. You might as well use 

if ($select->rows) {
   print(h1( {class=>'cyan'}, "Error occured $row->{username}! Script 
+have to die" ));
   exit(0);
}

There is a readable one-line, however: 

sub fatal_error {
   print(h1( {class=>'cyan'}, @_);
   exit(0);
}

fatal_error("Error occured $row->{username}! Script have to die")
   if $select->rows;
