本文主要介绍RDS SQL Server实例如何查看锁。
执行如下SQL语句，查看RDS SQL Server实例的锁。
SELECT dm_tran_locks.request_session_id,
dm_tran_locks.resource_database_id,
DB_NAME(dm_tran_locks.resource_database_id) AS dbname,
CASE
WHEN resource_type = 'OBJECT' THEN OBJECT_NAME(dm_tran_locks.resource_associated_entity_id)
ELSE OBJECT_NAME(partitions.OBJECT_ID)
END AS ObjectName,
partitions.index_id,
indexes.name AS index_name,
dm_tran_locks.resource_type,
dm_tran_locks.resource_description,
dm_tran_locks.resource_associated_entity_id,
dm_tran_locks.request_mode,
dm_tran_locks.request_status
FROM sys.dm_tran_locks
LEFT JOIN sys.partitions ON partitions.hobt_id = dm_tran_locks.resource_associated_entity_id
LEFT JOIN sys.indexes ON indexes.OBJECT_ID = partitions.OBJECT_ID
AND indexes.index_id = partitions.index_id
WHERE resource_associated_entity_id > 0
AND resource_database_id = DB_ID()
ORDER BY request_session_id,
resource_associated_entity_id ;
