Cause: A trigger (or a user defined PL/SQL function that is referenced in this statement) attempted to look at (or modify) a table that was in the middle of being modified by the statement which fired it.Action: Rewrite the trigger (or function) so it does not read that table.我的理解:当你删除DATATRANSFER_REF_ID时是否级连删除 DataTransfer_RunSequence 中的数据,由于你的select语句使该行别锁定,删除时出错
你上面的select没什么作用,把它删了试试看
