一个根据SortOrder控制排序的存储过程
2024-06-09 18:28:35
表结构如：
CREATE PROCEDURE dbo.emb_Performance_Tactic_UpdateSortOrder
(
@TacticID uniqueidentifier,
@MoveUp bit
)
AS
SET Transaction Isolation Level Read UNCOMMITTED --设置事务
BEGIN
SET NOCOUNT ON
--定义变量
DECLARE @currentSortValue int --当前SortOrder值
DECLARE @replaceSortValue int --要替换的SortOrder值
DECLARE @replaceTacticID uniqueidentifier --要替换的TacticID值
DECLARE @ParentTacticID uniqueidentifier --当前父TacticID值
--获取当前的SortOrder值
SELECT @currentSortValue = SortOrder, @ParentTacticID = ParentTacticID FROM EMB_Performance_Tactic WHERE TacticID = @TacticID
--上移还是下移
IF (@MoveUp = 1)
BEGIN
--上移操作
--获取要替换的SortOrder
SELECT @replaceSortValue = COALESCE(t.SortOrder, -1), @replaceTacticID = COALESCE(t.TacticID, '{00000000-0000-0000-0000-000000000000}')
FROM EMB_Performance_Tactic t
inner join (
select top 1 *
from EMB_Performance_Tactic
WHERE ParentTacticID = @ParentTacticID and SortOrder < @currentSortValue order by SortOrder DESC
) as pf on
pf.TacticID = t.TacticID
if( @replaceSortValue != -1 )
begin
UPDATE EMB_Performance_Tactic SET SortOrder = @currentSortValue WHERE TacticID = @replaceTacticID --更新要替换项的SortOrder为当前值
UPDATE EMB_Performance_Tactic SET SortOrder = @replaceSortValue WHERE TacticID = @TacticID --更新当前项的SortOrder为要替换项的SortOrder值
END
END
ELSE
BEGIN
--下移操作
SELECT @replaceSortValue = COALESCE(t.SortOrder, -1), @replaceTacticID = COALESCE(t.TacticID, '00000000-0000-0000-0000-000000000000')
FROM EMB_Performance_Tactic t
inner join (
select top 1 *
FROM EMB_Performance_Tactic

) as pf on
pf.TacticID = t.TacticID
if( @replaceSortValue != -1 )
BEGIN
UPDATE EMB_Performance_Tactic SET SortOrder = @currentSortValue WHERE TacticID = @replaceTacticID
UPDATE EMB_Performance_Tactic SET SortOrder = @replaceSortValue WHERE TacticID = @TacticID
END
END
END
/**//* COALESCE用法。
1、返回多个表达式中非空值的数据，如果所有表达式均为Null，则返回Null
2、多表达式必须是相同类型，或者可以隐性转换为相同类型。

附加另一个例子:
1.数据表设计如下:
