sql server 统计出来的内存,不管是这个,还是dbcc memorystatus,和进程管理器中内存差距很大,差不多有70G的差异. 具体原因不止,可能是内存泄漏,目前只能通过重启服务解决   Process/System Counts                    Value ---------------------------------------- -------------------- Available Physical Memory               

SQLSERVER排查CPU占用高的情况 今天中午,有朋友叫我帮他看一下数据库,操作系统是Windows2008R2 ,数据库是SQL2008R2 64位 64G内存,16核CPU 硬件配置还是比较高的,他说服务器运行的是金蝶K3软件,数据库实例里有多个数据库 现象 他说是这几天才出现的,而且在每天的某一个时间段才会出现CPU占用高的情况 内存占用不太高,只占用了30个G CPU占用100% 排查方向 一般排查都是用下面的脚本,一般会用到三个视图sys.sysprocesses ,dm_exec

最近在给一家客户做系统维护时,需要查看数据库表的大小,相关的sql如下: 先在左上角下拉框中选对要查的数据库再执行以下语句 1. exec sp_spaceused '表名'          --(SQL统计数据,大量事务操作后可能不准)2. exec sp_spaceused '表名', true       --(准确的表空间大小,但可能会花些统计时间)3. exec sp_spaceused                   -- (数据库大小查询)4. exec sp_MSforea

查询sql语句占用 CPU详细信息: SELECT (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_sta

删除数据库表 第一步: 执行 delete from doc.115sou.com        #删除数据,执行效率低 drop table doc.115sou.com          #删除表,效率一般 或 truncate table doc.115sou.com #清空表,效率高,推荐 执行完后发现空间大小无变化,没事,不着急 第二步: DBCC SHRINKDATABASE ( doc.115sou.com) 去看文件大小吧,是不是小了很多

遇到一情况,前几天创建一个表,但是后来忙别的事情了,现在要用这个表,结果失忆了.....完全想不起来表名. 然后就想办法查询表的创建时间试图找回表名 最后找到了,根据表的创建时间排序,因为平常也用不到,直接记录下 select * from sys.tables order by create_date desc

SELECT 表名 = case when a.colorder= then d.name else '' end, 表说明 = case when a.colorder= then isnull(f.value,'') else '' end, 字段序号 = a.colorder, 字段名 = a.name, 标识 = case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')= then '√'else '' end, 主键 = case when

两条命令 1:set statistics time on 这条命令会显示你编译这条语句和执行这条语句花多长时间 2.set statistics io on 这条命令会显示你逻辑读取了多少次数据库和物理上读取了多少次数据库 大致效果是这样的:
