Hi all, I have a script running collecting data in multiple wikipedia(s), I started to notice that revision table in lbwiki_p has some incorrect data. Here is an example: mysql> select rev_id, rev_user, rev_page, rev_deleted, rev_len, rev_timestamp from revision where rev_id = 185751; +--------+----------+----------+-------------+---------+----------------+ | rev_id | rev_user | rev_page | rev_deleted | rev_len | rev_timestamp | +--------+----------+----------+-------------+---------+----------------+ | 185751 | 580 | 83446 | 0 | NULL | 20061203231418 | +--------+----------+----------+-------------+---------+----------------+ mysql> select rev_id, rev_page, rev_len from revision where rev_page = 83446 and rev_timestamp < 20061203231418; +--------+----------+---------+ | rev_id | rev_page | rev_len | +--------+----------+---------+ | 115478 | 83446 | NULL | | 118003 | 83446 | NULL | | 118009 | 83446 | NULL | | 138010 | 83446 | NULL | +--------+----------+---------+ According to my understanding if a record exist rev_len shouldn't be NULL, if the revision deleted then rev_deleted should get flag but rev_length should remain as it is. Hope someone can look into this, because people who are doing analysis might end up getting wrong results. Best; -- Anuradha Uduwage (Anu)
