查询SERVER正在执行的SQL语句

--方法一
select * from  master..sysprocesses

SELECT  distinct   [Spid] = session_Id, ecid, [Database] = DB_NAME(sp.dbid),
 [User] = nt_username, [Status] = er.status, 
 [Wait] = wait_type, 
 [Individual Query] = SUBSTRING(qt.text, er.statement_start_offset / 2, (CASE WHEN er.statement_end_offset = - 1 THEN LEN(CONVERT(NVARCHAR(MAX), qt.text)) 
                      * 2 ELSE er.statement_end_offset END - er.statement_start_offset) / 2),
                       [Parent Query] = qt.text, 
                       Program = program_name, Hostname, 
                       nt_domain, start_time
FROM    
     sys.dm_exec_requests er INNER JOIN  sys.sysprocesses sp ON er.session_id = sp.spid 
     CROSS APPLY sys.dm_exec_sql_text(er.sql_handle) AS qt
WHERE     session_Id > 50 /* Ignore system spids.*/ AND session_Id NOT IN (@@SPID)

--方法二

SELECT  
  [session_id],
  [blocking_session_id] AS '正在阻塞其他会话的会话ID',
  DB_NAME([database_id]) AS '数据库名称',
  [request_id],
  [cpu_time],
  [start_time] AS '开始时间',
  [status] AS '状态',
  [command] AS '命令',
  dest.[text] AS 'sql语句', 
  [reads] AS '物理读次数',
  [writes] AS '写次数',
  [logical_reads] AS '逻辑读次数',
  [row_count] AS '返回结果行数',
  [wait_type] AS '等待资源类型',
  [wait_time] AS '等待时间',
  [wait_resource] AS '等待的资源'
  FROM sys.[dm_exec_requests] AS der 
  CROSS APPLY 
  sys.[dm_exec_sql_text](der.[sql_handle]) AS dest 
  WHERE  DB_NAME([database_id])='YBKPIMSDB'
   ORDER BY [session_id] DESC 

--方法三(查询最近执行的SQL）
SELECT deqs.last_execution_time AS [Time], dest.TEXT AS [Query]
FROM sys.dm_exec_query_stats AS deqs
CROSS APPLY sys.dm_exec_sql_text(deqs.sql_handle) AS dest
ORDER BY deqs.last_execution_time DESC
