摘要:
下文讲述sql脚本编写中,将 特定值排在最前面的方法分享,
实验环境:sqlserver 2008 R2
例:将数据表中指定值为0的行排在最前面呈现给用户
create table test(keyId int identity,info varchar(10),flag int)
go insert into test(info,flag)values ('a',-100),('b',-2),('C',-3)
,('d',2),('e',4),('f',8),('g',9),('h',0),('e',1),('f',0)
go ---将flag值等于0的放入最前面显示
select * from test order by
case when flag =0 then 0 else 1 end ,
flag asc
go ---将flag值等于2的放入最前面显示
select * from test order by
case when flag =2 then 0 else 1 end ,
flag asc
go go
truncate table test
drop table test
