What about the SHOW CREATE TABLE? Will that maintain everything about the
table structure? We're importing a new data set and previous code does a
"truncate table" then an import into the table. Since the report is live,
I'd rather avoid just whacking the data and hoping we can get the new data
in place...

CREATE TABLE `table_name` (
   `stuff1` int(9) NOT NULL default '0',
   `stuff2` char(1) NOT NULL default '',
   `stuff3` date NOT NULL default '0000-00-00',
   `stuff4` int(4) NOT NULL default '0',
   PRIMARY KEY  (`stuff1`),
   KEY `stuff2` (`stuff2`),
   KEY `stuff3` (`stuff3`),
   KEY `stuff4` (`stuff4`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 |

That all looks correct to me. SHOW INDEX comes up with the same indexes as
the original table has.
