Question

我有一个要求，要从数据库中检索用户的手机号码，且不能重复，因此我使用与众不同关键字来做到这一点。

也并非所有手机号码的格式都正确，因此我使用Case来格式化号码。

最后我想获取最新的500个手机号码，所以我想按ID by desc的顺序进行订购，但显示

ORDER BY items must appear in the select list if SELECT DISTINCT is specified.

以下是我的查询

 select distinct top 500  case 

                     when len(PhoneNumber) = 13 And phoneNumber  like '+311%' then replace(PhoneNumber, '+311', '0')
                     when len(PhoneNumber) = 13 And phoneNumber  like '311-%' then replace(PhoneNumber, '311-', '0')

                     when len(PhoneNumber) = 13 And phoneNumber  like '0311%' then stuff(PhoneNumber, 1, 4 , 0 )

                     when len(PhoneNumber) = 14 And phoneNumber  like '00311%'then stuff(PhoneNumber, 1, 5 ,'0')
                     when len(PhoneNumber) = 14 And phoneNumber  like '00311%' then stuff(PhoneNumber, 1, 4 ,'0')


                     when len(PhoneNumber) = 12 And phoneNumber  like '311%' then stuff(PhoneNumber, 1 , 3 , '0')
                     when len(PhoneNumber) = 12 then REPLACE (PhoneNumber, '-', '')

                     when len(PhoneNumber) = 11 And phoneNumber  like '00%' then Stuff(PhoneNumber, 1, 2 , '0')
                     else PhoneNumber
                end 


from users where  cityid = 1 and statusid = 1  and  (len(PhoneNumber) >= 10 And len(PhoneNumber) <= 14) 
and PhoneNumber not like '"%' and PhoneNumber not like '+311-%' and PhoneNumber not like '01%'
and PhoneNumber  like '0%'

Order by id

更新

正如Metal所建议的那样，我正在使用row_number（）并进行分区，这给了我一个手机号码，这是不正确的结果

select top 500000 Mobile
from 
    (select 
        row_number() over (partition by PhoneNumber order by id desc) rn,
        case 
        when len(PhoneNumber) = 13 And phoneNumber  like '+966%' then replace(PhoneNumber, '+966', '0')
        when len(PhoneNumber) = 13 And phoneNumber  like '966-%' then replace(PhoneNumber, '966-', '0')
        when len(PhoneNumber) = 13 And phoneNumber  like '0966%' then stuff(PhoneNumber, 1, 4 , 0 )
        when len(PhoneNumber) = 14 And phoneNumber  like '00966%'then stuff(PhoneNumber, 1, 5 ,'0')
        when len(PhoneNumber) = 14 And phoneNumber  like '0096%' then stuff(PhoneNumber, 1, 4 ,'0')
        when len(PhoneNumber) = 12 And phoneNumber  like '966%' then stuff(PhoneNumber, 1 , 3 , '0')
        when len(PhoneNumber) = 12 then REPLACE (PhoneNumber, '-', '')
        when len(PhoneNumber) = 11 And phoneNumber  like '00%' then Stuff(PhoneNumber, 1, 2 , '0')
        else PhoneNumber
        end  as Mobile
    from consigneeDetail 
    where  cityid = 1 and statusid = 1  and  (len(PhoneNumber) >= 10 And len(PhoneNumber) <= 14) 
            and PhoneNumber not like '"%' and PhoneNumber not like '+966-%' and PhoneNumber not like '01%'
            and PhoneNumber  like '0%') t1
where rn = 1
