mysql_num_rows ( resource result)

DELETE query, use mysql_affected_rows().

Huomaa:
If you use mysql_unbuffered_query(),
mysql_num_rows() will not return the
correct value until all the rows in the result set have been
retrieved.
See also:
mysql_affected_rows(),
mysql_connect(),
mysql_data_seek(),
mysql_select_db(), and
mysql_query().
For downward compatibility mysql_numrows() can
also be used. This is deprecated however.
