Hi folks I`m trying to get the number of records from a query on a MySql database but I`m having some trouble. The query itself is the following?

$result = mysql_query("SELECT * FROM tbLinks ORDER BY id DESC", $connection);

How do I get the number of records that came as a result?

After running the query use mysql_num_rows.


$num_rows = mysql_num_rows($result);

You use
int mysql_num_rows ( resource $result )

The other option would be to use mysql count by changing your query to the following.

$result = mysql_query("SELECT count(id) AS total FROM tbLinks ORDER BY id DESC", $connection);

if ($row = mysql_fetch_assoc($result)) {
 echo $row['total'].' rows';

Just my point on this, if all that is required is a count of the records then using mysql count() is much quicker. See following discussions on the topic:


However I will accept your point on the ORDER BY in the clause, that was perhaps sloppy on my part and is not needed with the count().

The query would be much better written as follows:
SELECT count(id) AS total FROM tbLinks

aikimark, the reason I decided to award the points to ncoo is that he had one of the first answers and even got to the point to offer a different solution, that even if it was not as elegant it was easy fr me to understand and classify it as the winner.
