Question

我需要将数据插入到TBL_LOAN_DETAILS表中。当调用LoanDetails()方法时，这些数据需要插入表中，TBL_LOAN_DETAILS中的ID是自动递增的。在将数据插入到TBL_LOAN_DETAILS之后，我需要获取该记录ID以便通过参数传递CribProcess()中另一种称为LoanDetails()的方法。在此之后，经过一些计算/逻辑后，我需要更新TBL_LOAN_DETAILS的某些列。为了实现我使用以下代码。（我无法在此处粘贴完整的代码，因为stackoverflow阻止了它，所以我使用pastebin）。我在此行lAEntities.TBL_LOAN_DETAILS.Add(tBlLoanDetails);的编程点之后没有刹车。lAEntities.SaveChanges();

我的部分代码：请使用链接检查我的完整代码。

运行程序后，TBL_LOAN_DETAILS表被锁定，这意味着，当我尝试使用oracle sql developer删除表时，此oracle错误消息显示。

ORA-00054：资源正忙并且在指定了NOWAIT或超时的情况下进行获取过期

Answer 1

由于您正在使用事务，因此您需要执行COMMIT或ROLLBACK。如果不这样做，则将出现当前所遇到的错误，因为无论您是否使用了using关键字并将其清除，该事务仍在使用记录。

您可以删除锁的方法是重新启动运行oracle的服务，或者杀死持有锁的oracle中的进程。之后，oracle将执行自己的ROLLBACK进程，并且锁将消失。
