Oracle 数据库在 UPDATE 查询中无限挂起
突然我的更新查询没有执行.我可以进行选择查询，但是当我尝试更新记录时，数据库无限挂起.我什至从 sql plus 尝试过，但没有任何反应.
suddenly my update queries are not executing . i can make select queries but when i try to update records the database hangs infinitly. i tried even from sql plus and nothing happens.
推荐答案
很可能您有另一个未提交的未提交事务用于同一组记录，因此它们已针对该事务锁定.
Most likely you have another open uncommitted transaction for the same set of records, so they are locked for that transaction.
而且，很可能你锁定了它们，在另一个事务中运行相同的UPDATE.
And, most likely, you locked them, running the same UPDATE in another transaction.
只要提交/回滚你的交易，你应该没问题.
Just Commit/rollback your transactions, you should be fine.
