查看SQLSERVER当前正在运行的sql信息

能够使用SQL Profiler捕捉在SQL Server实例上运行的活动。这种活动被称为Profiler跟踪。这个就不多说了，大家都知道，以下是使用代码为实现同样的效果。

SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED

 SELECT  [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))
