if googled a lot about this topic. I had made a lot of tries like altering tables or delete product flat tables. Nothing seems to work.

I tried also the magento database repair tool. Same exception.

Could anyone help me to fix this?

Thanks

Have you checked the MySQL privilages of the user connecting? ie, make sure the user in `app/etc/local.xml` can create tables and alter them as well within in MySQL. — B00MER, Oct 10 '12 at 15:08

Hey thanks for your answer. Something strange happened. I had to move my Shop to a new Server. Dumped the whole DB und moved to the new Server. After success i tryed after a long time to reindex the product flat and now it works o.o i don't know what happened but it works. :))) — boti, Jan 24 '13 at 09:12

The last time I had a reindexing issue, I added this to my mysql config file (/etc/my.cnf)

key_buffer = 512M
max_allowed_packet = 64M
table_cache = 512
sort_buffer_size = 4m
read_buffer_size = 4m
read_rnd_buffer_size = 2m
myisam_sort_buffer_size = 64m
tmp_table_size = 128m
query_cache_size = 96m
query_cache_type = 1
thread_cache_size = 8
max_connections = 400
wait_timeout = 300

You may also need to delete a lock file in magento/var/locks/
