獲取SQLSERVER中產生鎖的SQL語句

SELECT 
    SUBSTRING(st.text, (qs.statement_start_offset/2) + 1,((CASE statement_end_offset  WHEN -1 THEN DATALENGTH(st.text)  ELSE qs.statement_end_offset END - qs.statement_start_offset)/2) + 1) as statement_text
FROM sys.dm_exec_query_stats as qs CROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) as st where qs.sql_handle in (select distinct sql_handle from sys.dm_exec_requests where session_id in (SELECT request_session_id as Spid
FROM sys.dm_tran_locks l
LEFT JOIN sys.partitions p
ON l.resource_associated_entity_id = p.hobt_id
LEFT JOIN sys.indexes i
ON p.object_id = i.object_id
AND p.index_id = i.index_id
LEFT JOIN sys.objects o
ON p.object_id = o.object_id
LEFT JOIN sys.schemas s
ON o.schema_id = s.schema_id
LEFT JOIN sys.objects o2
ON l.resource_associated_entity_id = o2.object_id
LEFT JOIN sys.schemas s2
ON o2.schema_id = s2.schema_id
LEFT JOIN sys.databases db
ON l.resource_database_id = db.database_id
WHERE resource_database_id = DB_ID() and request_mode in ("X")
))

查詢 某個時間點的，所有執行中的sql語句的CPU占用時間（倒排序）

use master;SELECT [session_id], [cpu_time], [start_time], dest.[text] AS "sql",  DB_NAME([database_id]) AS "dbname", [row_count] FROM sys.[dm_exec_requests] AS der CROSS APPLY sys.[dm_exec_sql_text](der.[sql_handle]) AS dest WHERE [session_id]>50 ORDER BY [cpu_time] DESC

查詢 不同sql語句產生阻塞的情況（主要是由于鎖產生的等待）

use master;SELECT top 50 dest.[text] AS "sql", wtt.blocking_session_id, wtt.wait_duration_ms, wtt.session_id FROM sys.dm_os_waiting_tasks wtt LEFT JOIN sys.dm_exec_requests req ON wtt.blocking_session_id = req.session_id CROSS APPLY sys.[dm_exec_sql_text](req.[sql_handle]) AS dest where wtt.blocking_session_id is not null and wtt.wait_duration_ms>2000 order by wait_duration_ms desc
