SQL整体更新的方法

如果在项目中遇到用户在客户端编辑数据,添加数据.SQL整体更新到数据库里面，应该怎么做呢？下面就将教您如何进行SQL整体更新，供您参考。
数据库结构:

DataSet ds=new DataSet();读取数据  
    private void button1_Click(object sender, System.EventArgs e)  
        {  
            //  
            string str_Conn="workstation id=JHTCHINA;packet size=4096;user id=sa;initial catalog=master;persist security info=False";  
            try  
            {  
                SqlConnection objConn=new SqlConnection(str_Conn);  
                string str_sql="select * from Test_Base";  
                SqlCommand objComm=new SqlCommand(str_sql,objConn);  
                SqlDataAdapter objAdapter=new SqlDataAdapter(objComm);                 
                objAdapter.Fill(ds,"Test_Base");  
                dataGrid1.DataSource=ds;  
            }  
            catch (Exception exc)  
            {  
                MessageBox.Show(exc.Message);  
            }  
        }

CREATE TABLE [Test_Base] (
    [CodeZZB] [nvarchar] (50) COLLATE Chinese_PRC_CI_AS NOT NULL ,
    [InterName] [nvarchar] (100) COLLATE Chinese_PRC_CI_AS NULL ,
    [Guid] [nvarchar] (50) COLLATE Chinese_PRC_CI_AS NOT NULL CONSTRAINT [DF_LoginPerson_Guid] DEFAULT (newid()),
    CONSTRAINT [PK_Test_Base] PRIMARY KEY CLUSTERED
    (
        [CodeZZB]
    ) ON [PRIMARY]
) ON [PRIMARY]
GO

定义全局DataSet

DataSet ds=new DataSet();读取数据  
    private void button1_Click(object sender, System.EventArgs e)  
        {  
            //  
            string str_Conn="workstation id=JHTCHINA;packet size=4096;user id=sa;initial catalog=master;persist security info=False";  
            try  
            {  
                SqlConnection objConn=new SqlConnection(str_Conn);  
                string str_sql="select * from Test_Base";  
                SqlCommand objComm=new SqlCommand(str_sql,objConn);  
                SqlDataAdapter objAdapter=new SqlDataAdapter(objComm);                 
                objAdapter.Fill(ds,"Test_Base");  
                dataGrid1.DataSource=ds;  
            }  
            catch (Exception exc)  
            {  
                MessageBox.Show(exc.Message);  
            }  
        }

编辑添加dataGrid以后更新数据

private void button2_Click(object sender, System.EventArgs e)  
        {              
            try  
            {                  
                //这里ds.Table[0]里面的数据已经改变  
                string str_Conn="workstation id=JHTCHINA;packet size=4096;user id=sa;initial catalog=master;persist security info=False";  
                //整体把修改的数据更新到数据库里面  
                SqlConnection objConn=new SqlConnection(str_Conn);  
                string str_sql="select * from Test_Base";  
                SqlCommand objComm=new SqlCommand(str_sql,objConn);   
                SqlDataAdapter objAdapter=new SqlDataAdapter(objComm);  
                SqlCommandBuilder updataBulid=new SqlCommandBuilder(objAdapter);  
                objAdapter.Update(ds,"Test_Base");  
                  
                MessageBox.Show("OK");  
 
            }  
            catch  (Exception exc)  
            {  
                MessageBox.Show(exc.Message);  
            }  
        }
