要开发用户管理系统,我们首先要了解需求,现在就举一个简单需求,用户表,假设有两种角色用一个字段departID来判断,管理员和员工,

我们要先建一个用户表custom和一个部门表department:

CREATE TABLE [dbo].[custom](
 [id] [int] IDENTITY(1,1) NOT NULL,
 [cname] [nvarchar](50) COLLATE Chinese_PRC_CI_AS NOT NULL,
 [departID] [int] NOT NULL,
 [age] [int] NOT NULL,
 [ename] [nvarchar](50) COLLATE Chinese_PRC_CI_AS NOT NULL,
 [password] [nvarchar](50) COLLATE Chinese_PRC_CI_AS NOT NULL,
 CONSTRAINT [PK_custom] PRIMARY KEY CLUSTERED 
(
 [id] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY];

CREATE TABLE [dbo].[department](
 [id] [int] IDENTITY(1,1) NOT NULL,
 [departname] [nvarchar](50) COLLATE Chinese_PRC_CI_AS NOT NULL,
 [description] [nchar](10) COLLATE Chinese_PRC_CI_AS NOT NULL,
 CONSTRAINT [PK_department] PRIMARY KEY CLUSTERED 
(
 [id] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

建完数据库表后,开始写存储过程,插入一条数据:

CREATE PROCEDURE [dbo].[spInsertCustom]
@cname nvarchar(50),
@ename nvarchar(50),
@age int,
@departID int,
@password nvarchar(50)
AS
BEGIN
insert into custom(cname,departID,age,ename,password) values (@cname,@departID,@age,@ename,@password)
END

RETURN @@Identity

现建两个更新一条数据的存储过程:

CREATE PROCEDURE [dbo].[spupdatecustom] 
@id int,
@cname nvarchar(50),
@departID int,
@age int,
@ename nvarchar(50),
@password nvarchar(50)
AS
BEGIN
 update 
       custom 
    set
    cname = @cname,
    departID = @departID,
    age = @age,
    ename = @ename,
    password = @password
    where id = @id
END
COMMIT TRAN

再新建两个取出所有用户的存储过程:

CREATE PROCEDURE [dbo].[spGetcustom]
 
AS
BEGIN
 select * from custom order by id desc
END

再新建一个根据ID取出一条数据的存储过程:

CREATE PROCEDURE [dbo].[spGetcustomer]
@id int
AS
BEGIN
 select * from custom where id = @id
END
