mysql_affected_rows() or mysql_num_rows() for select statment

[ Milos911 @ 21.10.2011. 10:10 ] @

Navikao sam da radim ovako:

Code:
mysql_query("SELECT blablabla");
if(mysql_affected_rows()>0){
something is found, proceed
}else{
nothing is found
}

Manual kaze

Citat:

Note: SELECT Statements
To retrieve the number of rows returned by a SELECT, it is possible to use mysql_num_rows().

Meni mysql_affected_rows() uvek, ali uvek vraca >0 ako je nesto nadjeno. A koristim ga bas mnogo. Sad, zanima me koliko je pogresno ovo raditi, i da li ima bolji nacin za proveru da li je nesto nadjeno u bazi od ovog mog koda?
