GRIDVIEW中實現上移下移的存儲過程

建一個表  t_hoteladvertise

有如下字段：
ID  自動增長(主要)
SortID  INT (主要)
Title  NVARCHAR(50)

 

CREATE proc sp_ehotel_DownAdvertise

@ID INT
as
DECLARE @SortID int
DECLARE @TempSortID INT
DECLARE @TempID INT

BEGIN  TRAN

SELECT @SortID=SortID  from t_hoteladvertise where [ID]=@ID

SELECT @TempSortID=max(SortID) from t_hoteladvertise where SortID>@SortID
SELECT @TempID=[ID] from t_hoteladvertise WHERE SortID=@TempSortID

if @@error>0 or @@rowcount<>1
goto NeedRollBack

UPDATE t_hoteladvertise SET SortID=@SortID WHERE [ID]=@TempID

if @@error>0 or @@rowcount<>1
goto NeedRollBack

UPDATE t_hoteladvertise SET SortID=@TempSortID where [ID]=@ID

 NeedRollBack:
if @@error>0 or @@rowcount<>1
  rollback tran
else
commit tran
GO

CREATE proc sp_ehotel_UpAdvertise
@ID INT
as
DECLARE @SortID int
DECLARE @TempSortID INT
DECLARE @TempID INT

BEGIN  TRAN

SELECT @SortID=SortID  from t_hoteladvertise where [ID]=@ID

SELECT @TempSortID=max(SortID) from t_hoteladvertise where SortID<@SortID
SELECT @TempID=[ID] from t_hoteladvertise WHERE SortID=@TempSortID

if @@error>0 or @@rowcount<>1
goto NeedRollBack

UPDATE t_hoteladvertise SET SortID=@SortID WHERE [ID]=@TempID

if @@error>0 or @@rowcount<>1
goto NeedRollBack

UPDATE t_hoteladvertise SET SortID=@TempSortID where [ID]=@ID

 NeedRollBack:
if @@error>0 or @@rowcount<>1
  rollback tran
else
commit tran
GO
