五、项目创建

建表SQL

CREATE TABLE [dbo].[tb_user] (
[id] int NOT NULL IDENTITY(1,1) ,
[Name] varchar(20) NULL ,
[Gender] varchar(10) NULL ,
[Address] varchar(70) NULL ,
[Status] int NOT NULL ,
[UpdateTime] date NOT NULL
)GO
DBCC CHECKIDENT(N'[dbo].[tb_user]', RESEED, 8)
GO-- ----------------------------
-- Records of tb_user
-- ----------------------------
SET IDENTITY_INSERT [dbo].[tb_user] ON
GO
INSERT INTO [dbo].[tb_user] ([id], [Name], [Gender], [Address], [Status], [UpdateTime]) VALUES (N'1', N'张三', N'男', N'***省***市***街道', N'0', N'2021-08-21');

Index视图层

}<h2>员工疫情状态信息</h2>
