检视数据库连接信息

create proc uf_getlinkinfo @dbname sysname=null,--要查询的数据库名,默认查询所有数据库的连接信息 @includeip bit=0--是否显示IP地址,因为查询IP地址比较费时,所以增加此控制 as declare @dbid int set @dbid=db_id(@dbname) create table #tb(id int identity(1,1),dbname sysname,hostname nchar(128),loginname nchar(128),net_address nchar(12),net_ip nvarchar(15),prog_name nchar(128)) insert into #tb(hostname,dbname,net_address,loginname,prog_name) select distinct hostname,db_name(dbid),net_address,loginame,program_name from master..sysprocesses where hostname<>'' and (@dbid is null or dbid=@dbid) if @includeip=0 goto lb_show --如果不显示IP地址,就直接显示 declare @sql varchar(500),@hostname nchar(128),@id int create table #ip(hostname nchar(128),a varchar(200)) declare tb cursor local for select distinct hostname from #tb open tb fetch next from tb into @hostname while @@fetch_status=0 begin set @sql='ping '+@hostname+' -a -n 1 -l 1' insert #ip(a) exec master..xp_cmdshell @sql update #ip set hostname=@hostname where hostname is null fetch next from tb into @hostname end update #tb set net_ip=left(a,patindex('%:%',a)-1) from #tb a inner join ( select hostname,a=substring(a,patindex('Ping statistics for %:%',a)+20,20) from #ip where a like 'Ping statistics for %:%') b on a.hostname=b.hostname lb_show: select id,数据库名=dbname,客户机名=hostname,用户名=loginname ,网卡物理地址=net_address,IP地址=net_ip,应用程序名称=prog_name from #tb GO
