如果每次$ eg-> db-> affected_rows()返回时，如何知道codeigniter中已删除的行数.成功还是失败

How to know the no of deleted rows in codeigniter provided that $this->db->affected_rows() returns every time ie. on success or on fail also

我不使用CodeIgniter，但通常， affected_rows()应该返回受影响的行数.这意味着，如果查询成功，则始终应为整数.如果返回0，则不删除任何行；如果> 0，则删除该行.

I don't use CodeIgniter, but normally, affected_rows( ) should return the number of rows affected. That means, if the query succeeded, it should always be an integer. If 0 is returned, no rows are deleted, if > 0, that number is deleted.
