Dynamic SQL generation for the UpdateCommand is not supported against a SelectCommand that does not return any key column information."

数据保存出此错误信息:Dynamic SQL generation for the UpdateCommand is not supported against a SelectCommand that does not return any key column information.
经查是因为做了一个备份表,而影响了数据表tablename的结构,导致pk不见,而备份tablename1的pk 为tablename_pk,造成了冲突,使得DS分不清是非.
看来数据更新备份的时候要再慎重再小心.
