    <p>When it comes to repairing and checking tables, MySQL offers two options:</p> <ol> <li>The MySQL distribution ships with a tool called "<a href="http://dev.mysql.com/doc/refman/5.0/en/myisamchk.html" rel="nofollow">myisamchk</a>," designed specifically to check and repair MyISAM tables (the default table type used by MySQL). This tool can scan your databases, identify problems, optimize tables for faster lookup, and optionally repair corrupted tables. The myisamchk tool is invoked from the command line.</li> <li><p>In addition to the tool above, MySQL also allows you check and repair tables using SQL commands. The CHECK TABLE, <a href="http://dev.mysql.com/doc/refman/5.1/en/repair-table.html" rel="nofollow">REPAIR TABLE</a>, and OPTIMIZE TABLE commands can be used on a running MySQL server and need to be entered through a MySQL client.</p> <blockquote> <p>Eg: REPAIR [NO_WRITE_TO_BINLOG | LOCAL] TABLE tbl_name [, tbl_name] ... [QUICK] [EXTENDED] [USE_FRM]</p> </blockquote></li> </ol> <p>Most of the time, it's preferable to use myisamchk because it is significantly faster than using SQL commands.</p> <p>Concerning the "auto" part of the repairing, I suggest not to make a habit from repairing tables. Sounds to me like you'r looking for a pump to remove water from a leak. Would the obvious thing not be to fix the leak and cause of the problem?</p> <p>Remove some memory heavy functions or upgrade your server. Relying on a script or something else to auto-repair corrupted tables is a bad idea.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
