Description:

Mysql_affected_rows () returns the number of columns affected by the last query as an INSERT, update, or delete, assuming that the last-opened link is used if no link identifier is specified.

If the last query is delete and there is no where directive, all records will be removed from the table, but this function will return 0.

This function is not valid if the last query uses the SELECT command.
