My client reported the a case to me.  He said one mysql table lost some of
the data.  The table structure is shown as follows:
+-----------------------+---------------+------+-----+---------+-------+
| Field                 | Type          | Null | Key | Default | Extra |
+-----------------------+---------------+------+-----+---------+-------+
| uid                   | varchar(32)   |      | PRI |         |       |
| createdate            | datetime      | YES  |     | NULL    |       |
| lastmoddate           | datetime      | YES  |     | NULL    |       |
| num_of_files          | int(13)       | YES  |     | NULL    |       |
| createby              | varchar(32)   | YES  |     | NULL    |       |
| field_107666797596432 | varchar(255)  | YES  | MUL | NULL    |       |
| field_107666798773233 | varchar(255)  | YES  | MUL | NULL    |       |
| field_107666808467434 | varchar(255)  | YES  | MUL | NULL    |       |
| field_107666809745535 | decimal(13,5) | YES  | MUL | NULL    |       |
| field_107666813934636 | varchar(255)  | YES  | MUL | NULL    |       |
| field_107666815016037 | varchar(255)  | YES  | MUL | NULL    |       |
| field_107666815625938 | text          | YES  |     | NULL    |       |
+-----------------------+---------------+------+-----+---------+-------+
The fields "field_xxxxx" lost data in most of the records, but no data was
lost on other fields.  Do you think it is possible?  I'm guessing that it is
caused by the corrupted index file.  Does it help if I repair the index
file?  Your suggestion is greatly appreciated as I need to suggest my client
how to recover the data.
