mysql_affected_ rows() question

MS
Hi,

I'm doing a table insert and have a question about mysql_affected_ rows().

The following code works. It correctly inserts the row and
mysql_affected_ rows() returns 1 as it should do.

$sql = "INSERT INTO member (company, username, password, cookie,
session, ip) VALUES ('$company', '$user', '$pass', 'fakecookie',
'fakesession', '192.168.1.1')" ;

$result = mysql_query($sq l) or MyDie("Error: ".mysql_error() );

// Determine success:
// mysql_affected_ rows returns the number of affected rows on
// success, and -1 if the last query failed.

$rowsAffected = mysql_affected_ rows();
However the final line, the call to mysql_affected_ rows, used to have
$result as an argument, like this:

$rowsAffected = mysql_affected_ rows($result);

Which as far as I can tell is correct. When I use that line, the row gets
inserted correctly, but the call to mysql_affected_ rows() fails, with the
following error message:

"Warning: mysql_affected_ rows(): supplied argument is not a valid
MySQL-Link resource in /home/fakeuser/public_html/test/adduser.php on line
104"

I don't understand why it is not a valid link resource. The almost
identical code, but making a 'select' query and not doing an 'insert',
works fine when checking with 'mysql_num_rows ($result)'.

Obviously this is not critical, since I've got it working, but in the
interests of increasing my understanding can someone explain this problem
to me please.

Many thanks.

"Warning: mysql_affected_ rows(): supplied argument is not a valid
MySQL-Link resource in /home/fakeuser/public_html/test/adduser.php on
line 104"
PHP Manual:
For SELECT, SHOW, DESCRIBE, EXPLAIN and other statements returning
resultset, mysql_query() returns a resource on success, or FALSE on error.
For other type of SQL statements, UPDATE, DELETE, DROP, etc,
mysql_query() returns TRUE on success or FALSE on error.

So: Because TRUE is not a Resource, which is expected.
Ha, that was easy.

Indeed, mysql_affected_ rows() does NOT expect the return value of
mysql_query(), but the connection resource:

So, to but it in a nutshell: RTFM!

Oh, I'm so sorry! I did RTFM, but *obviously* not very effectively.

Thanks for the help.

Feeling humbled and very sorry.

Well, you shouldn't feel humbled and very sorry, but only sorry.
Don't exaggerate :)

Don't worry about it. This area of mysql can be confusing. So many of
the calls take a result from mysql_query(), and you would think that
this one would, also.

But alas, it's (one of) the exception(s) to the "rule". :-)

Two questions in a row.. I'm on a roll :) When i perform UPDATEs in my admin system, I'm checking for success by using mysql_affected_rows() and this works fine if data is changed and updated. However, if a user submits an admin page without chaning any details, the SQL executes fine, but mysql_affected_rows() returns 0 as MySQL is clever enough to work out that nothing changed.

Hi, So I read the manual where it says to use mysql_affected_rows() for everything except SELECT and SHOW, and use mysql_num_rows() for those two, which actually return a result. However, I wrote this little script below where I find that mysql_num_rows() returns exactly the same output in the case of SELECT, as mysql_affected_rows(). In the case of the INSERT, mysql_num_rows() does not return anything.
