oracle数据库查询表被锁多种方式实现

SELECT object_name, object_type  
FROM v$locked_object  
WHERE object_type = 'TABLE';

SELECT o.object_name, l.lock_type  
FROM dba_objects o  
JOIN dba_locks l ON o.object_id = l.object_id  
WHERE o.object_type = 'TABLE'  
AND o.object_name = '你的表名';

SELECT s.sid, s.serial#, s.username, l.object_id, o.object_name  
FROM v$session s  
JOIN v$lock l ON s.sid = l.sid  
JOIN dba_objects o ON l.object_id = o.object_id  
WHERE o.object_type = 'TABLE'  
AND o.object_name = '你的表名';

SELECT b.sid AS blocking_session,  
       w.sid AS waiting_session,  
       o.object_name  
FROM dba_blockers b  
JOIN dba_waiters w ON b.sid = w.blocking_session  
JOIN dba_objects o ON w.object_id = o.object_id  
WHERE o.object_type = 'TABLE'  
AND o.object_name = '你的表名';

SELECT sid, type, lmode, request, id1, id2  
FROM v$lock  
WHERE id1 IN (SELECT object_id FROM dba_objects WHERE object_name = '你的表名' AND object_type = 'TABLE');
