存储过程 给表排序

前家公司用到过没想到很快又遇到这问题了 那就照搬吧 不一样的地方也就表名与字段名

现在数据表需要用到排序功能，正好跟之前排序功能一样 干脆照搬一下前人写的代码觉得以后还会继续用到 就留着吧

期间也是用到一级 二级排序功能

USE [IstudyMMMMMMM]
GO

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER PROCEDURE  [dbo].[HobbyTypeOrder]
AS
BEGIN
 --处理一级类型内部排序
 UPDATE dbo.S_HobbyType SET innerOrderID = X.innerOrderID
	FROM S_HobbyType
	JOIN (SELECT T.TypeID,T.TypeName,T.level,T.ParentID, ROW_NUMBER() OVER (ORDER BY T.innerOrderID) innerOrderID
		FROM dbo.S_HobbyType T
		WHERE  T.level = 1)
	 X
	 ON X.TypeID = S_HobbyType.TypeID;
	  --处理二级类型内部排序
	 UPDATE dbo.S_HobbyType SET innerOrderID = X.innerOrderID
	FROM S_HobbyType
	JOIN (SELECT T.TypeID,T.TypeName,T.level,T.ParentID, ROW_NUMBER() OVER (PARTITION BY T.ParentID ORDER BY T.innerOrderID) innerOrderID
		FROM dbo.S_HobbyType T
		WHERE    T.level = 2)
	 X
	 ON  X.TypeID = S_HobbyType.TypeID;

   --处理全局排序号
 WITH CET AS
	(
		SELECT  L.TypeID,l.ParentID,L.level, dbo.CalcTreeNodeOrder(9,1024,level,InnerOrderID, NULL) GlobalOrder FROM dbo.S_HobbyType L WHERE   level = 1
		UNION ALL
		SELECT L.TypeID,L.ParentID,L.level, dbo.CalcTreeNodeOrder(9,1024,L.level,L.InnerOrderID,CET.GlobalOrder) GlobalOrder FROM dbo.S_HobbyType L JOIN CET ON L.ParentID = CET.TypeID
	)

	UPDATE dbo.S_HobbyType SET GlobalOrderID = X.GlobalOrderID
	FROM S_HobbyType JOIN (SELECT TypeID,ROW_NUMBER() OVER (ORDER BY CET.GlobalOrder) GlobalOrderID FROM CET) X ON X.TypeID = dbo.S_HobbyType.TypeID;

END

CalcTreeNodeOrder：
