--先創(chuàng)建一個表?
create table ai(?
id int not null,?
no varchar(10) not null?
)?
go?

--往表中插入數(shù)據(jù)?
insert into ai?
?select 105,'2'?
?union all?
?select 105,'1'?
?union all?
?select 103,'1'?
?union all?
?select 105,'4'?
go?

--查詢效果如下:?
select * from ai?
go?
id????????? no?????????
----------- ----------?
105???????? 2?
105???????? 1?
103???????? 1?
105???????? 4?


i.?
--要求的查詢結(jié)果如下?
--即要求no列的數(shù)據(jù)按'4','1','2'排列?
id????????? no?????????
----------- ----------?
105???????? 4?
105???????? 1?
103???????? 1?
105???????? 2

--解決方案1?
--利用函數(shù)CHARINDEX?
select * from ai?
?order by charindex(no,'4,1,2')?

--解決方案2?
--利用函數(shù)case?
select * from ai?
?order by case when no='4' then 1?
??????? when no='1' then 2?
????????????????????? when no='2' then 3?
???????????????? end?

--解決方案3?
--利用UNION 運算符?
select * from ai?
?where no='4'?
union all?
select * from ai?
?where no='1'?
union all?
select * from ai?
?where no='2'?

ii.?
--查詢要求指定no='4'排第一行，其他的行隨機(jī)排序?
id????????? no?????????
----------- ----------?
105???????? 4?
105???????? 2?
105???????? 1?
103???????? 1?

--解決方案?
select * from ai?
?order by case when no='4' then 1?
???else 1+rand()?
??end?

iii.?
--查詢要求所有行隨機(jī)排序

--解決方案?
select * from ai?
?order by newid()?


iiii?
--有一表ab有列i，其中數(shù)據(jù)如下：?
i varchar(10)?
a1?
a10?
a101?
a5?
p4?
p41?
p5?


--現(xiàn)在要求列i中數(shù)據(jù)先按字母排序，再按數(shù)字排序?
--效果如下：?
a1?
a5?
a10?
a101?
p4?
p5?
p41?

--解決方案?
select * from ab?
?order by left(i,1),convert(int,substring(i,2,8000))
