@subsubsection Corrupted MyISAM tables.
Even if the MyISAM table format is very reliable (all changes to a table
is written before the SQL statements returns) , you can still get
corrupted tables if some of the following things happens:
@itemize @bullet
@item
The @code{mysqld} process being killed in the middle of a write.
@item
Unexpected shutdown of the computer (for example, if the computer is turned
off).
@item
A hardware error.
@item
You are using an external program (like myisamchk) on a live table.
@item
A software bug in the MySQL or MyISAM code.
@end itemize
Typial typical symptoms for a corrupt table is:
@itemize @bullet
@item
You get the error @code{Incorrect key file for table: '...'. Try to repair it}
while selecting data from the table.
@item
Queries doesn't find rows in the table or returns incomplete data.
@end itemize
You can check if a table is ok with the command @code{CHECK
TABLE}. @xref{CHECK TABLE}.
You can repair a corrupted table with @code{REPAIR TABLE}. @xref{REPAIR TABLE}.
You can also repair a table, when @code{mysqld} is not running with
the @code{myisamchk} command. @code{myisamchk syntax}.
If your tables get corrupted a lot you should try to find the reason for
this! @xref{Crashing}.
In this case the most important thing to know is if the table got
corrupted if the @code{mysqld} died (one can easily verify this by
checking if there is a recent row @code{restarted mysqld} in the mysqld
error file). If this isn't the case, then you should try to make a test
case of this. @xref{Reproduceable test case}.
