Is there a problem with the MySQL version?

ALTER TABLE `goods_sku` ADD `member_price` int(11) unsigned NOT NULL DEFAULT "0" COMMENT "" AFTER `price`;

Why prompt:

 1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near "ALTER TABLE `juhe_menu_store_goods_sku` ADD `member_price` int(11) unsigned NOT " at line 1

I tried and there was no problem.

MySQL Query : SELECT * FROM `codeshelper`.`v9_news` WHERE status=99 AND catid='6' ORDER BY rand() LIMIT 5
MySQL Error : Disk full (/tmp/#sql-temptable-64f5-1eb4a4a-24f1.MAI); waiting for someone to free some space... (errno: 28 "No space left on device")
