mysql_query(): how to check whether any rows are updated in case of UPDATE SQL

Question

I am using mysql_query() to execute UPDATE SQL on my table. I want to know whether the query has updated any row or not.

    // $query contains UPDATE SQL
$result = mysql_query($query, $connection);
if(!$result) {
    die("Database connection failed: " . mysql_error());
}

I tried to check value of $result, but it always comes out to be 1 for both cases(0 or more than 0 rows updated).

Can anyone please help.

Thanks.

Answer 1

Use mysql_affected_rows(). It returns the number of modified rows in the last query run.

$numRows = mysql_affected_rows($connection).

Answer 2

Try using mysql_affected_rows().

Answer 3

For completeness, you may also find this answer in SQL via the ROW_COUNT() function, although mysql_affected_rows is better for this task.
