  -v, --version       print version and exit.   -w, --wait          wait if table is locked. check options (check is the default action for myisamchk):   -c, --check         check table for errors   -e, --extend-check  check the table very throughly.  only use this in                       extreme cases as myisamchk should normally be able to                       find out if the table is ok even without this switch   -f, --fast          check only tables that haven't been closed properly   -c, --check-only-changed                       check only tables that have changed since last check   -f, --force         restart with '-r' if there are any errors in the table.                       states will be updated as with '--update-state'   -i, --information   print statistics information about table that is checked   -m, --medium-check  faster than extend-check, but only finds 99.99% of                       all errors.  should be good enough for most cases   -u  --update-state  mark tables as crashed if you find any errors   -t, --read-only     don't mark table as checked repair options (when using '-r' or '-o')   -b, --backup        make a backup of the .myd file as 'filename-time.bak'   --correct-checksum  correct checksum information for table.   -d, --data-file-length=#  max length of data file (when recreating data                       file when it's full)   -e, --extend-check  try to recover every possible row from the data file                       normally this will also find a lot of garbage rows;                       don't use this option if you are not totally desperate.   -f, --force         overwrite old temporary files.   -k, --keys-used=#   tell myisam to update only some specific keys. # is a                       bit mask of which keys to use. this can be used to                       get faster inserts!   -r, --recover       can fix almost anything except unique keys that aren't                       unique.   -n, --sort-recover  forces recovering with sorting even if the temporary                       file would be very big.   -p, --parallel-recover                       uses the same technique as '-r' and '-n', but creates                       all the keys in parallel, in different threads.                       this is alpha code. use at your own risk!   -o, --safe-recover  uses old recovery method; slower than '-r' but can                       handle a couple of cases where '-r' reports that it                       can't fix the data file.   --character-sets-dir=...                       directory where character sets are   --set-character-set=name                       change the character set used by the index   -q, --quick         faster repair by not modifying the data file.                       one can give a second '-q' to force myisamchk to                       modify the original datafile in case of duplicate keys   -u, --unpack        unpack file packed with myisampack. other actions:   -a, --analyze       analyze distribution of keys. will make some joins in                       MySQL faster.  you can check the calculated distribution                       by using '--description --verbose table_name'.   -d, --description   prints some information about table.   -a, --set-auto-increment[=value]                       force auto_increment to start at this or higher value                       if no value is given, then sets the next auto_increment                       value to the highest used value for the auto key + 1.   -s, --sort-index    sort index blocks.  this speeds up 'read-next' in                       applications   -r, --sort-records=#                       sort records according to an index.  this makes your                       data much more localized and may speed up things c:\mysql\bin>myisamchk c:\mysql\data\hw_enterprice\function_products.frm myisamchk: error: 'c:\mysql\data\hw_enterprice\function_products.frm' is not a m yisam-table c:\mysql\bin>myisamchk c:\mysql\data\hw_enterprice\function_products.myi checking myisam file: c:\mysql\data\hw_enterprice\function_products.myi data records:   85207   deleted blocks:      39 myisamchk: warning: table is marked as crashed myisamchk: warning: 1 clients is using or hasn't closed the table properly - check file-size - check key delete-chain - check record delete-chain myisamchk: error: record delete-link-chain corrupted - check index reference - check data record references index: 1 - check data record references index: 2 - check data record references index: 3 - check record links myisamchk: error: wrong bytesec: 0-195-171 at linkstart: 841908 myisam-table 'c:\MySQL\data\hw_enterprice\function_products.myi' is corrupted fix it using switch "-r" or "-o"
