While trying to get a handle on PendingEditRepBonus
in the Data Explorer, I stumbled across an undocumented mystery in the DB. For example, thousands of posts with no "valid" PostHistoryType
.
According to the "Database schema documentation for the public data dump and Data Explorer", and this answer to "Magic number in Data Explorer should be documented", there are only 22 PostHistoryType
s.
Yet the current DE snapshot shows:
PostHistoryTypeId Name Count ----------------- -------------------- ------- 1 Initial Title 1846229 2 Initial Body 6016252 3 Initial Tags 1846229 4 Edit Title 223205 5 Edit Body 2070256 6 Edit Tags 430688 7 Rollback Title 2612 8 Rollback Body 10558 9 Rollback Tags 4323 10 Post Closed 36189 11 Post Reopened 1752 12 Post Deleted 31862 13 Post Undeleted 31842 14 Post Locked 2728 15 Post Unlocked 211 16 Community Owned 105436 17 Post Migrated 4201 18 Question Merged 3661 19 Question Protected 1874 20 Question Unprotected 58 21 Post Dissociated 57 23 null 29 24 null 63936 26 null 13 27 null 80 28 null 57 29 null 37 30 null 1
What are these mysterious values for PostHistoryType
?
