While statement problems

[Anon]

I have this while statement and I want to say when it does not meet this while statements condition to print there is nothing for you to see here. How can I do this?

while ($Row2 = mysql_fetch_array($Result2)) {
print (\"<TR ALIGN=CENTER VALIGN=TOP>\n\");
print (\"<TD ALIGN=CENTER VALIGN=TOP>$Row2[Session_ID]</TD>\n\");

						print (\"</TR>\\n\");

}

if (mysql_num_rows($Result2) == 0) {
print "There is nothing";
} else {
while ($Row2 = mysql_fetch_array($Result2)) {
print (\"<TR ALIGN=CENTER VALIGN=TOP>\n\");
print (\"<TD ALIGN=CENTER VALIGN=TOP>$Row2[Session_ID]</TD>\n\");

print (\"</TR>\n\");
}
}
