SQL While循环60秒？

我基本上试图捕获sql命令和CPU的等待时间,我只想运行一个while循环60秒并将所有数据插入到临时表中.我在游标时不是很好,或者如何在sql中完成这个.

BEGIN
   CREATE TABLE #DiagTable
   (
      sessionID          NVARCHAR (MAX),
      dbname             NVARCHAR (MAX),
      starttime          NVARCHAR (MAX),
      cmd                NVARCHAR (MAX),
      stat               NVARCHAR (MAX),
      cputime            NVARCHAR (MAX),
      totalelapsedtime   NVARCHAR (MAX),
      reads              NVARCHAR (MAX),
      writes             NVARCHAR (MAX),
      [query]            NVARCHAR (MAX)
   )

   DECLARE @id   INT



   DECLARE
      x CURSOR FOR
         SELECT 60

   OPEN x

   FETCH NEXT FROM x   INTO @id



   WHILE @@FETCH_STATUS = 0
   BEGIN
      WAITFOR DELAY '000:00:01'

      -- begin loop here
      INSERT INTO #DiagTable
         SELECT a.session_id,
                db_name (a.database_id) AS db_name,
                a.start_time,
                a.command,
                a.status,
                a.cpu_time,
                a.total_elapsed_time,
                a.reads,
                a.writes,
                b.text AS query
           FROM sys.dm_exec_requests a
                OUTER APPLY sys.dm_exec_sql_text (a.sql_handle) b
          WHERE a.session_id > 50               -- filter out background tasks
                                 AND a.session_id  @@spid -- filter out this query session
         ORDER BY a.cpu_time DESC;

      WAITFOR DELAY '00:00:01'

      FETCH NEXT FROM x   INTO @id
   END

   CLOSE x

   DEALLOCATE x

   -- end loop here
   SELECT * FROM #DiagTable;

   DROP TABLE #DiagTable;
END

不确定选择60是否是我想要的......
