Dear All
I have a problem with mysql_num_rows
if I execute it on a result returned by mysql_query,,, and that
result is empty then I will get an error saying that this result is not a
valid mysql result
I am using count(*) and checking if my SQL statements will return
more than 0 results,, but because i am using InnoDB engine, it is very
inefficient to use count(*) very much because it will search the whole
table
any Idea how to solve this?
regards
