省市区三级的存储过程，自动添加地区的存储过程问题

创建省的表结构：
CREATE TABLE [G_Cfg_SndMap_Province] (
[ProvinceID] [int] NOT NULL CONSTRAINT [DF_G_Cfg_SndMap_Province_ProvinceID] DEFAULT (0),
[ProvinceName] [varchar] (20) COLLATE Chinese_PRC_CI_AS NULL CONSTRAINT [DF_G_Cfg_SndMap_Province_ProvinceName] DEFAULT (''),
[ProvinceName2] [varchar] (20) COLLATE Chinese_PRC_CI_AS NULL CONSTRAINT [DF_G_Cfg_SndMap_Province_ProvinceName2] DEFAULT (''),
[Remark] [varchar] (50) COLLATE Chinese_PRC_CI_AS NULL CONSTRAINT [DF_G_Cfg_SndMap_Province_Remark] DEFAULT (''),
[DefaultLogistic] [varchar] (20) COLLATE Chinese_PRC_CI_AS NULL CONSTRAINT [DF_G_Cfg_SndMap_Province_DefaultLogistic] DEFAULT (''),
CONSTRAINT [PK_G_Cfg_SndMap_Province] PRIMARY KEY CLUSTERED
(
[ProvinceID]
) WITH FILLFACTOR = 100 ON [PRIMARY]
) ON [PRIMARY]
GO

创建市的表结构：
CREATE TABLE [G_Cfg_SndMap_City] (
[CityID] [int] NOT NULL ,
[ProvinceID] [int] NULL CONSTRAINT [DF_G_Cfg_SndMap_City_ProvinceID] DEFAULT (0),
[CityName] [varchar] (30) COLLATE Chinese_PRC_CI_AS NULL CONSTRAINT [DF_G_Cfg_SndMap_City_CityName] DEFAULT (''),
[CityName2] [varchar] (30) COLLATE Chinese_PRC_CI_AS NULL CONSTRAINT [DF_G_Cfg_SndMap_City_CityName2] DEFAULT (''),
[Remark] [varchar] (50) COLLATE Chinese_PRC_CI_AS NULL CONSTRAINT [DF_G_Cfg_SndMap_City_Remark] DEFAULT (''),
[DefaultLogistic] [varchar] (20) COLLATE Chinese_PRC_CI_AS NULL CONSTRAINT [DF_G_Cfg_SndMap_City_DefaultLogistic] DEFAULT (''),
CONSTRAINT [PK_G_Cfg_SndMap_City] PRIMARY KEY CLUSTERED
(
[CityID]
) WITH FILLFACTOR = 100 ON [PRIMARY]
) ON [PRIMARY]
GO


创建区的表结构内容 ：
CREATE TABLE [G_Cfg_SndMap_Area] (
[AreaID] [int] NOT NULL ,
[CityID] [int] NULL ,
[AreaName] [varchar] (40) COLLATE Chinese_PRC_CI_AS NULL CONSTRAINT [DF_G_Cfg_SndMap_Area_AreaName] DEFAULT (''),
[AreaName2] [varchar] (20) COLLATE Chinese_PRC_CI_AS NULL CONSTRAINT [DF_G_Cfg_SndMap_Area_AreaNam2] DEFAULT (''),
[Remark] [varchar] (20) COLLATE Chinese_PRC_CI_AS NULL CONSTRAINT [DF_G_Cfg_SndMap_Area_Remark] DEFAULT (''),
[DefaultLogistic] [varchar] (20) COLLATE Chinese_PRC_CI_AS NULL CONSTRAINT [DF_G_Cfg_SndMap_Area_DefaultLogistic] DEFAULT (''),
[LogisticArea] [varchar] (40) COLLATE Chinese_PRC_CI_AS NULL CONSTRAINT [DF_G_Cfg_SndMap_Area_LogisticArea] DEFAULT (''),
CONSTRAINT [PK_G_Cfg_SndMap_Area] PRIMARY KEY CLUSTERED
(
[AreaID]
) WITH FILLFACTOR = 100 ON [PRIMARY]
) ON [PRIMARY]
