假如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？接下来的SQL server内容就将教您如何进行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); } }
运行通过
假如是SQL整体更新添加,在数据读取的时候
string str_sql="select * from Test_Base where 1=2";
一句代码就可以了
