Sorry, Anthony. Yes, I meant the MySQL archive tables (mediatitles_archive
in this case).
I'm looking at the table(s) using the command line MySQL console. This is
what it says:
...a couple of sample records from the mediatitles table (id 511 is an
updated record created after logging in as an alternate user - the akaname
changed)
mysql> select * from mediatitles;
| id | name | akaname
| progress | used_in | cnt| is_active | created_on |
created_by | modified_on | modified_by |
| 510 | I’m On My Way | I’m On My Way
| p16021491 | |cur| | 0 | T | 2017-06-14 14:18:09 | 1
| 2017-06-14 14:18:09 | 1 |
| 511 | (#R43) Mary Had A Little Lamb | #R43 - Mary Had A Little Lamb
Anne 4 | p16021544 | |cur| | 0 | T | 2017-06-14 14:18:09 | 1
| 2017-06-15 10:17:19 | 2 |
...and the mediatitles archive table - empty :(
mysql> select * from mediatitles_archive;
Empty set (0.00 sec)
