以下のストアドプロシージャを作成しています。
declare @PageNum as Int
declare @PerPageResult as Int
declare @StartDate as varchar(25)
declare @EndDate as varchar(25)
declare @SortType as Varchar(50)
declare @SortDirection as Varchar(4)
set @PageNum=1
set @PerPageResult=20
set @StartDate='2008-02-08'
set @EndDate='2015-02-08'
set @SortType='RegDate'
set @SortDirection='Desc'
declare @Temp Table(RowNum int, RegDate Date, Registered int, Female int, Male int, [Join] int, Rebill int, TotalPointsEarned int, Expire int)
declare @sort varchar(50)
Insert into @Temp
Select ROW_NUMBER() over (order by @SortType+' '+@SortDirection) As RowNum, * From (
SELECT
CAST(m.registrationdate AS Date) as RegDate,
count(m.id) Registered,
count(CASE WHEN m.gender='F' then 'F' end) As Female,
count(CASE WHEN m.gender='M' then 'M' end) As Male
count(CASE WHEN p.paymenttransactiontype='N' then 'N' end) As [Join],
count(CASE WHEN p.paymenttransactiontype='R' then 'R' end) As Rebill,
count(m.tokensearned) As TotalPointsEarned,
count(CASE WHEN p.paymenttransactiontype='E' then 'E' end) As Expire
from member m
join payment p on m.id=p.id_member
join user_role u on u.member_id=m.id
where u.role_id <> 3
and CAST(m.registrationdate AS Date) > @StartDate and CAST(m.registrationdate AS Date) < @EndDate
GROUP BY CAST(m.registrationdate AS Date)
) as aa
Select * from @Temp Where RowNum>((@PageNum-1)*@PerPageResult) and RowNum<=@PerPageResult * @PageNum
Order by @SortType+' '+@SortDirection
上記の節を動的に渡すとOrder by
、データが適切にソートされませんが、列名を明示的に記述すると正常に動作します。@SortType+' '+@SortDirection
というvarchar
よりもDate
書いてみOrder by case when (@Sort='RegDate' and @SortDirection='Desc') Then RegDate End Desc
たけどダメだった
ここで動的に注文を渡すにはどうすればよいですか。
編集: @Andomar: 提供されたソリューションを試し、日付型のフィールドをもう 1 つ追加しました。そして、それもうまくいきませんでした。
以下は私がしたことです。
create table t1 (id int, name varchar(50), dt date);
insert t1 values
(1, 'Chihiro Ogino','2009-02-08'),
(2, 'Spirit of the Kohaku River','2008-02-08'),
(3, 'Yubaba','2012-02-08');
declare @sortColumn varchar(50) = 'dt'
declare @sortOrder varchar(50) = 'ASC'
select *
from t1
order by
case
when @sortOrder <> 'ASC' then 0
when @sortColumn = 'id' then id
end ASC
, case
when @sortOrder <> 'ASC' then ''
when @sortColumn = 'name' then name
end ASC
, case
when @sortOrder <> 'ASC' then ''
when @sortColumn = 'dt' then name
end ASC
, case
when @sortOrder <> 'DESC' then 0
when @sortColumn = 'id' then id
end DESC
, case
when @sortOrder <> 'DESC' then ''
when @sortColumn = 'name' then name
end DESC
, case
when @sortOrder <> 'DESC' then ''
when @sortColumn = 'dt' then name
end DESC
