I had to do something a little more involved, as myisamchk claimed
programgenres was not a MyISAM table! For the benefit of others
searching the list archives, here is what I did (as root so I had
appropriate permissions). Edit paths and table names as needed.
shell$ cd /home/mysql/mythconverg
shell$ cp programgenres.MYI ~/mythtv/.
shell$ mysql -p mythconverg
mysql$ set autocommit = 1;
mysql$ truncate table programgenres;
shell$ cp ~/mythtv/programgenres.MYI .
shell$ myisamchk -r programgenres
This dropped 1289 records, but fixed the table index. I can now see the
records, and operation is back to normal.
Thanks for your help, Glenn.
