我正在为我的CMS使用嵌套集,但是从MySQL 5.5起我无法移动节点.
抛出以下错误:

重新排序文档时出错:MySQL-DB出错:SQL无效:

 SELECT baum2.id AS id,
 COUNT(*) AS level
 FROM elisabeth_tree AS baum1,
 elisabeth_tree AS baum2
 WHERE baum2.lft BETWEEN baum1.lft AND baum1.rgt
 GROUP BY baum2.lft
 ORDER BY ABS(baum2.id - 6);

错误:BIGINT UNSIGNED值超出范围在'( ..lektoren - 6)' 的错误编号:1690baum2id

有没有人解决过这个问题？我已经尝试过铸造一些零件但是没有成功.
