然后定义一个SqlCommandBuilder SqlCommandBuilder thisBuilder = new SqlCommandBuilder(adapter ); 一开始我不知道这句有啥用...参考请看：http://blog.163.com/kongdelu2009@yeah/blog/static/111995207200932111175638/ 这个SqlCommandBuilder
Sub btnUpdate_Click(sender As Object, e As EventArgs) Handles btnUpdate.Click Dim SCB = New SqlCommandBuilder...DataGridView1.Rows.RemoveAt(DataGridView1.CurrentCell.RowIndex) '数据库中进行删除 Dim SCB = New SqlCommandBuilder...3.SqlCommandBuilder对象： SqlCommandBuilder builder =new SqlCommandBuilder(已创建的DataAdapter对象); 利用SqlCommandBuilder
SqlDataAdapter(); sqlDataAdapter.SelectCommand = sqlCommand; DataSet dataSet = new DataSet(); //sqlCommandBuilder...is for update the dataset to database SqlCommandBuilder sqlCommandBuilder = new SqlCommandBuilder(sqlDataAdapter
//dataTable.Rows[1].Delete(); SqlCommand cmd = new SqlCommand(); SqlCommandBuilder... objCommandBuilder = new SqlCommandBuilder(da); cmd=objCommandBuilder.GetDeleteCommand
adapter = new SqlDataAdapter(s, conn); 创建SqlCommandBuilder对象 创建这个对象，需要传入SqlDataAdapter的对象。...方法会报一个异常:System.InvalidOperationException: 当传递具有已修改行的 DataRow 集合时，更新要求有效的 UpdateCommand scb = new SqlCommandBuilder...private DataSet data ; //这样会让SqlDataAdapter对象自动实现与DataSet更改和关联的SQL语句 private SqlCommandBuilder...from Student"; adapter = new SqlDataAdapter(s, conn); scb = new SqlCommandBuilder
SqlDataAdapter ada = new SqlDataAdapter("select * from reader where 序号='" + i + "'", con); SqlCommandBuilder...com = new SqlCommandBuilder(ada); DataSet ds = new DataSet(); ada.Fill(ds, "
SqlDataAdapter thisadapter = new SqlDataAdapter("select * from reader where 条形码='" + txm + "'", con); SqlCommandBuilder...thisbuilder = new SqlCommandBuilder(thisadapter); DataSet thisdataset = new DataSet(); thisadapter.Fill
classPlace, classTeacher, classTitle, durativeDate FROM gch_Class_Info",sqlConnection1); SqlCommandBuilder... sqlCB1 = new SqlCommandBuilder(sqlDA1); sqlDA1.Fill(dataTable1); foreach(DataRow
GetSpSqlparameter 一种重载方法,用于检索指定存储过程中的相应参数(首先查询一次数据库,然后缓存结果,以便将来查询),该方法从缓存中检索存储过程的参数,如果存储过程中没有,那么就从.NET 的 SqlCommandBuilder
SqlDataAdapter sqlDataAdapter = new SqlDataAdapter("Select * from RWTest", sqlConnection); SqlCommandBuilder...sqlCommandBuilder = new SqlCommandBuilder(sqlDataAdapter); System.Data.DataSet dataSet...SqlDataAdapter sqlDataAdapter = new SqlDataAdapter("Select * from RWTest", sqlConnection); SqlCommandBuilder...sqlCommandBuilder = new SqlCommandBuilder(sqlDataAdapter); DataSet dataSet = new DataSet
dataAdapterClass="System.Data.SqlClient.SqlDataAdapter" commandBuilderClass="System.Data.SqlClient.SqlCommandBuilder...dataAdapterClass="System.Data.SqlClient.SqlDataAdapter" commandBuilderClass="System.Data.SqlClient.SqlCommandBuilder...dataAdapterClass="System.Data.SqlClient.SqlDataAdapter" commandBuilderClass=" System.Data.SqlClient.SqlCommandBuilder...dataAdapterClass="System.Data.SqlClient.SqlDataAdapter" commandBuilderClass=" System.Data.SqlClient.SqlCommandBuilder
private SqlCommand cmd;//定义数据命令对象 private SqlDataAdapter sqlada;//定义数据适配器对象 private SqlCommandBuilder
switch (dbType) { case DatabaseType.SQLServer: cmb = new SqlCommandBuilder...switch (dbType) { case DatabaseType.SQLServer: cmb = new SqlCommandBuilder
c.如何保持数据集中的数据 (1)使用SqlCommandBuilder对象生成更新用的相关命令 (2)调用DataAdapter对象的Update()方法 语法： DataAdapter 对象....Update(数据集对象,"数据表名称字符串"); 例如: SqlCommandBuilder builder=new SqlCommandBuilder(dataAdapter); dataAdapter.....Update(dataSet,"Teacher"); 经验: SqlCommandBuilder 只操作单个表，也就是说，我们创建DataAdapter对象时，使用的SQL语句只能从一个表里面查数据...DataGridView的属性和个列的属性 (3)指定DataGridView的数据源 c.如何保存修改后的数据 (1)增加"保存修改"按钮 (2)编写事件处理方法 d.常见错误 (1)不使用SqlCommandBuilder
ConnectionState.Open) { command.Connection.Open(); } SqlCommandBuilder.DeriveParameters
_dbProviderFactory is SqlClientFactory) 28: { 29: SqlCommandBuilder.DeriveParameters
SqlCommandBuilder.DeriveParameters(cmd); connection.Close(); // 如果不包含返回值参数,将参数集中的每一个参数删除
