Question

我正在收集一些SQL Server统计信息以进行升级计划。我发现了一些很好的查询，并对其进行了修改以满足我的要求。我想将每个查询的结果添加到表（SQLSTATS）中，该结果将进入相应的列。我正计划每隔N分钟通过SQL代理作业运行这些查询以收集数据。我将提出一项发现，以决定是否需要转移到磁盘优化，CPU优化，内存优化或网络优化的服务器上。任何帮助或指导，将不胜感激。

查询如下：

 --Disk I/O
    SELECT
        wait_time_ms/waiting_tasks_count AS 'PAGEIOLATCH_SH'
    FROM
       sys.dm_os_wait_stats 
    WHERE
       waiting_tasks_count > 0
   and wait_type = 'PAGEIOLATCH_SH'
ORDER BY
   wait_time_ms DESC

SELECT
    wait_time_ms/waiting_tasks_count AS 'PAGEIOLATCH_SH'
FROM
   sys.dm_os_wait_stats 
WHERE
   waiting_tasks_count > 0
   and wait_type = 'PAGEIOLATCH_EX'
ORDER BY
   wait_time_ms DESC


SELECT
    wait_time_ms/waiting_tasks_count AS 'PAGEIOLATCH_UP'
FROM
   sys.dm_os_wait_stats 
WHERE
   waiting_tasks_count > 0
   and wait_type = 'PAGEIOLATCH_UP'
ORDER BY
   wait_time_ms DESC


--Network
SELECT st.text AS [SQL_Text],
w.wait_type AS [Wait_Type]
FROM sys.dm_os_waiting_tasks AS w
INNER JOIN sys.dm_exec_connections AS c ON w.session_id = c.session_id
CROSS APPLY (SELECT * FROM sys.dm_exec_sql_text(c.most_recent_sql_handle))
AS st WHERE w.session_id > 50
AND w.wait_duration_ms > 0
AND WAIT_Type='ASYNC_NETWORK_IO'


--CPU
DECLARE @ts BIGINT;
DECLARE @lastNmin TINYINT;
SET @lastNmin = 1;
SELECT @ts =(SELECT cpu_ticks/(cpu_ticks/ms_ticks) FROM sys.dm_os_sys_info); 
SELECT TOP(@lastNmin)
        SQLProcessUtilization AS [SQLServer_CPU_Utilization]    
FROM (SELECT record.value('(./Record/@id)[1]','int')AS record_id, 
record.value('(./Record/SchedulerMonitorEvent/SystemHealth/SystemIdle)[1]','int')AS [SystemIdle], 
record.value('(./Record/SchedulerMonitorEvent/SystemHealth/ProcessUtilization)[1]','int')AS [SQLProcessUtilization], 
[timestamp]      
FROM (SELECT[timestamp], convert(xml, record) AS [record]             
FROM sys.dm_os_ring_buffers             
WHERE ring_buffer_type =N'RING_BUFFER_SCHEDULER_MONITOR'AND record LIKE'%%')AS x )AS y 
ORDER BY record_id DESC;

我已经在网上进行了一些广泛的搜索，但是找不到与我的问题相关的任何答案。我尝试将查询结果插入变量，然后从变量插入表->列。它没有用。请参见下面的代码：

Declare @PAGEIOLATCH_SH Nvarchar(50)
--IO Disk 
SET @PAGEIOLATCH_SH = (SELECT 
wait_time_ms/waiting_tasks_count AS 'PAGEIOLATCH_SH'
FROM
   sys.dm_os_wait_stats 
WHERE
   waiting_tasks_count > 0
   and wait_type = 'PAGEIOLATCH_SH')
PRINT @PAGEIOLATCH_SH

Select @PAGEIOLATCH_SH INTO SQLSTATS (pageiolatch_sh))

将多个Select语句的结果插入各自表中的一个表中
