当发现SQL Server 占用的资源过高，有时重启电脑也解决不了问题时，建议通过如下语句检查SQL语句的问题，
如果是当天出的问题增加{order by last_worker_time desc,想看一下今天哪些sql执行出现问题了}
SELECT s2.dbid, s1.sql_handle, (SELECT TOP 1 SUBSTRING(s2.text,statement_start_offset / 2+1 , ( (CASE WHEN statement_end_offset = -1 THEN (LEN(CONVERT(nvarchar(max),s2.text)) * 2) ELSE statement_end_offset END) - statement_start_offset) / 2+1)) AS sql_statement, execution_count, plan_generation_num, last_execution_time, total_worker_time, last_worker_time, min_worker_time, max_worker_time, total_physical_reads, last_physical_reads, min_physical_reads, max_physical_reads, total_logical_writes, last_logical_writes, min_logical_writes, max_logical_writes FROM sys.dm_exec_query_stats AS s1 CROSS APPLY sys.dm_exec_sql_text(sql_handle) AS s2 WHERE s2.objectid is null ORDER BY last_worker_time desc,s1.sql_handle, s1.statement_start_offset, s1.statement_end_offset;当
查last_worker_time为执行毫秒数
SQL Server 占用内存太高，查找占用内存高以及影响其性能的sql语句
