mysql_affected_rows -- Get number of affected rows in previous MySQL
operation Descriptionint mysql_affected_rows(int
[ link_identifier]
);
mysql_affected_rows() returns the number of
rows affected by the last INSERT, UPDATE or DELETE query on the
server associated with the specified link identifier. If the
link identifier isn't specified, the last opened link is assumed.
If the last query was a DELETE query with no WHERE clause, all
of the records will have been deleted from the table but this
function will return zero.
This command is not effective for SELECT statements, only on
statements which modify records. To retrieve the number of rows
returned from a SELECT, use mysql_num_rows().
