 `REPAIR TABLE' repairs a possibly corrupted table.  By default, it has
 the same effect as `myisamchk --recover TBL_NAME'.  `REPAIR TABLE'
 works only on `MyISAM' tables.
 Normally you should never have to run this statement. However, if
 disaster strikes, `REPAIR TABLE' is very likely to get back all your
 data from a `MyISAM' table.  If your tables become corrupted often, you
 should try to find the reason for it, to eliminate the need to use
 `REPAIR TABLE'.   Crashing.   `MyISAM' table problems

 The statement returns a table with the following columns:
 *Column*    *Value*
 `Table'     The table name
 `Op'        Always `repair'
 `Msg_type'  One of `status', `error', `info', or
 `Msg_text'  The message
 The `REPAIR TABLE' statement might produce many rows of information for
 each repaired table.  The last row will have a `Msg_type' value of
 `status' and `Msg_test' normally should be `OK'.  If you don't get
 `OK', you should try repairing the table with `myisamchk
 --safe-recover', because `REPAIR TABLE' does not yet implement all the
 options of `myisamchk'. We plan to make it more flexible in the future.
 If `QUICK' is given, `REPAIR TABLE' tries to repair only the index
 tree.  This type of repair is like that done by `myisamchk --recover
 If you use `EXTENDED', MySQL creates the index row by row instead of
 creating one index at a time with sorting.  (Before MySQL 4.1, this
 might be better than sorting on fixed-length keys if you have long
 `CHAR' keys that compress very well.)  This type of repair is like that
 done by `myisamchk --safe-recover'.
 As of MySQL 4.0.2, there is a `USE_FRM' mode for `REPAIR TABLE'.  Use
 it if the `.MYI' index file is missing or if its header is corrupted.
 In this mode, MySQL will re-create the `.MYI' file using information
 from the `.frm' file. This kind of repair cannot be done with
 `myisamchk'. * Use this mode *only* if you cannot use regular
 `REPAIR' modes. `.MYI' header contains important table metadata (in
 particular, current `AUTO_INCREMENT' value and `Delete link') that will
 be lost in `REPAIR ... USE_FRM'.  Don't use `USE_FRM' if the table is
 compressed, as this information is also stored in `.MYI' file.
 Before MySQL 4.1.1, `REPAIR TABLE' statements are not written to the
 binary log. As of MySQL 4.1.1, they are written to the binary log
 unless the optional `NO_WRITE_TO_BINLOG' keyword (or its alias `LOCAL')
 is used.
 *Warning:* If the server dies during a `REPAIR TABLE' operation, it's
 essential after restarting it that you immediately execute another
 `REPAIR TABLE' statement for the table before performing any other
 operations on it. (It's always good to start by making a backup.)  In
 the worst case, you might have a new clean index file without
 information about the data file, and then the next operation you
 perform could overwrite the data file.  This is an unlikely, but
 possible scenario.
