Really?

    cursor.execute('describe %s;' % store)
    storeDescription = cursor.fetchall()
    print storeDescription

Prints out this:

(('ID', 'tinyint(5) unsigned', 'NO', 'PRI', None, 'auto_increment'), ('SKU',
'varchar(40)', 'NO', 'UNI', None, ''), ('Category', 'varchar(40)', 'YES',
'', None, ''), ('Name', 'varchar(50)', 'NO', '', None, ''), ('Title',
'varchar(100)', 'NO', '', None, ''), ('Description', 'mediumtext', 'NO', '',
None, ''), ('Price', 'float(8,2)', 'YES', '', None, ''), ('SortFactor',
'int(4)', 'YES', '', '500', ''), ('Availability', 'tinyint(1)', 'NO', '',
None, ''), ('ShipFlatFee', 'float(5,2)', 'NO', '', '10.00', ''),
('ShipPercentPrice', 'tinyint(2) unsigned', 'NO', '', '5', ''),
('ShipPercentWeight', 'tinyint(2) unsigned', 'NO', '', '2', ''),
('Associations', 'varchar(40)', 'NO', '', None, ''), ('TempPrice',
'float(7,2)', 'NO', '', None, ''), ('LastDatePrice', 'date', 'NO', '', None,
''), ('Weight', 'float(7,2)', 'NO', '', None, ''), ('Metal', "enum('14k
gold','18k gold','white gold','silver','tungsten','titanium')", 'NO', '',
None, ''), ('PercentMetal', 'tinyint(2) unsigned', 'NO', '', None, ''),
('pic1', 'blob', 'YES', '', None, ''), ('pic2', 'blob', 'YES', '', None,
''), ('sizes',
"set('Extra-small','Small','Medium','Large','XLarge','XXLarge','XXXLarge')",
'YES', '', None, ''), ('colorsShadesNumbersShort',
"set('blue:333399','gray:465945','purple:50404D','navy-blue:CC7722','fuchsia:FF77FF','aqua:7FFFD4','maroon:B03060','black:0000FF','yellow:9ACD32','teal:E2725B','olive:6B8E23','green:00A550','white:0F4D92','silver:708090','red:FE2712','lime:32CD32')",
'YES', '', None, ''))

In my version of MySQL, he default value is in the fifth column of the

Nice. As you can see, I only get 4 columns by default. How do I get the
fifth?
