达梦数据库表被锁住后解锁方法：
第一步：首先查看当前数据库中锁的状态
执行sql：SELECT * FROM v$lock
此时可以看到 事务2399被阻塞了，阻塞他的事务是2393，同样我们也可以通过 V T R X W A I T 视 图 查 看 谁 阻 塞 谁 。 执 行
s q l ： S E L E C T ∗ F R O M V TRXWAIT 视图查看谁阻塞谁。 执行sql：SELECT * FROM VTRXWAIT视图
查看谁阻塞谁。执行sql：SELECT∗FROMVTRXWAIT;
得出同样的结果，ID 为 2399 的事务正在等待 ID 为 2393 的事务，等待时间是1071599 毫秒。
接下来，通过 V S E S S I O N S 视 图 查 找 两 个 事 务 对 应 的 会 话 。 执 行 s q l ： S E L E C T
s e s s i d , s q l t e x t , s t a t e , t r x i d F R O M V SESSIONS
视图查找两个事务对应的会话。 执行sql：SELECT sess_id,sql_text,state,trx_id FROM VSESSIONS视图查找两个事务
对应的会话。执行sql：SELECTsessid,sqltext,state,trxidFROMVSESSIONS;
第二步：解决方法
根据需求有两种解决办法：
第一种：提交或回滚产生阻塞的事务，此时，我们只需要在该会话下提交或回滚事务，锁自然会被释放，阻塞解决。
第二种：关闭产生阻塞的会话
同样，我们也可以使用系统过程 SP_CLOSE_SESSION(SESS_ID)来关闭对应的会话，具体使用方法如下。
执行sql：SP_CLOSE_SESSION(SESS_ID)
此时，被阻塞的锁已经被释放，相对应被锁的表已经被解锁可以正常使用，表就可以正常操作了。
