@楚云岫 在最新的beta5中验证了,BUG不存在,请提供进一步的证据,最好Debug一下,查到具体异常证明.还可以查看控制台输出的sql.
 
 Sql: select * from eova_object where code = ?
 Sql: select * from eova_field where object_code = ? order by fieldnum,order_num
 Sql: delete from `hotel_bed` where `id` = ?    根据ID删除的 咋可能会删除所有明细数据呢?
 Sql: insert into `eova_log`(`info`, `ip`, `type`, `user_id`) values(?, ?, ?, ?)

@Jieven 我的从表是复合主键

@楚云岫 eova 并没有默认对复合主键做什么,除非你DB层面有额外处理.甚至是只推荐也只支持单主键的
