解决方案
现在sqlserver也应该有decode了吧。select case a.alarmtype when 100 then '硬盘变更事件' when 2000 then '杀毒软件事件' when 2002 then '设备监控事件' when 2003 then '硬件监视事件' when 2004 then '软件监视事件' when 2005 then '主机防火墙事件' when 2006 then 'HTTP访问事件' when 2007 then '外联监控事件' when 2008 then '网络配置监控事件' when 2009 then '流量控制事件' when 2010 then '系统性能事件' when 2011 then '拨号监控事件' when 2012 then '文件监视事件' when 2013 then '补丁自动下发事件' when 2014 then '打印监控事件' when 2015 then '进程监视事件' when 2016 then '端口监视事件' when 2017 then '共享监视事件' when 2018 then 'USB监视事件' when 2020 then '流量统计事件' when 2022 then '文档检查事件' when 2023 then '网络准入事件' else '未知事件' end as label, count(a.alarmtype) as VALUE from td_eventinfo a where substr(a.groupurl,instr(a.groupurl, '/', -1, 1) + 1) = 'td' and a.creationtime BETWEEN to_date('20130304','yyyyMMdd') AND to_date('20130326','yyyyMMdd') group by a.alarmtype order by count(a.alarmtype) desc
