SQL查询Server服务器的名称和IP地址的实例
获取服务器名称：
SELECT SERVERPROPERTY('MachineName')
select @@SERVERNAME
select HOST_NAME()
获取IP地址可以使用xp_cmdshell执行ipconfig命令：
--开启xp_cmdshell
exec sp_configure'show advanced options', 1
reconfigure with override
exec sp_configure'xp_cmdshell', 1
reconfigure with override
exec sp_configure'show advanced options', 0
reconfigure with override
go
begin
declare @ipline varchar(200)
declare @pos int
declare @ip varchar(40)
set nocount on
set @ip = null
if object_id('tempdb..#temp') is not null drop table #temp
create table #temp(ipline varchar(200))
insert #temp exec master..xp_cmdshell'ipconfig'
select @ipline = ipline
from #temp
where upper(ipline) like '%IPv4 地址%'--这里需要注意一下，系统不同这里的匹配值就不同
if @ipline is not null
begin
set @pos = charindex(':',@ipline,1);
set @ip = rtrim(ltrim(substring(@ipline ,
@pos + 1 ,
len(@ipline) - @pos)))
end
select distinct(rtrim(ltrim(substring(@ipline ,
@pos + 1 ,
len(@ipline) - @pos)))) as ipaddress from #temp
drop table #temp
set nocount off
end
go
但是很多情况下由于安全问题是不允许使用xp_cmdshell，可以通过查询SYS.DM_EXEC_CONNECTIONS ：
SELECT SERVERNAME = CONVERT(NVARCHAR(128),SERVERPROPERTY('SERVERNAME'))
,LOCAL_NET_ADDRESS AS 'IPAddressOfSQLServer'
,CLIENT_NET_ADDRESS AS 'ClientIPAddress'
FROM SYS.DM_EXEC_CONNECTIONS WHERE SESSION_ID = @@SPID
