下面仅给出一些应该注意的地方的代码示例:
//
创建SqlServer类型的实例
DataHelper dhp = SqlServer.Create( " . " , " mshop " , " sa " , " 123 " );
// 如果是Access则使用 OleDb.Access.Create()
// 用DataSet填充DataGrid,并使用Update更新
DataSet dst = new DataSet();
dhp.OpenUpdateBag(); // 打开更新包
dhp.FillDataset( " select * from swxx " , dst, " aa " ); // 填充数据 指定表名称
dhp.FillDataset( " select * from user_info " , dst, " bb " );
dataGrid1.DataSource = dst;
dhp.CloseUpdateBag(); // 关闭更新包
// ..
// 更新DataSet
DataSet dst = (DataSet)dataGrid1.DataSource;
dhp.Update(dst);
// 事务操作
dhp.BeginTransaction(); // 开始事务
try
{
dhp.ExecuteNonQuery("delete from swxx where id = 1");
dhp.ExecuteNonQuery("delete from swxx where id = 2");
dhp.CommitTransaction(); //提交
}
catch
{
dhp.RollbackTransaction(); //回滚
}
// 执行存储过程
ParameterCollection pc = new ParameterCollection();
pc.Add( " @id " , 5 );
// 如果添加带返回的参数
pc.Add( " @return " , DbType.String, 20 );
dhp.ExecuteNonQuery( " deleteswxx " , pc);
// 执行带参数的sql语句
ParameterCollection pc = new ParameterCollection();
pc.Add( " @name " , " faib " );
pc.Add( " @sex " , true );
pc.Add( " @birthday " , DateTime.Today);
dhp.ExecuteNonQuery(pc.Format( " insert into userinfo({0}) values({1}) " ), pc);
// 或者更新
dhp.ExecuteNonQuery(pc.Format( " update userinfo set {0} where id = 1 " ), pc);
DataHelper dhp = SqlServer.Create( " . " , " mshop " , " sa " , " 123 " );
// 如果是Access则使用 OleDb.Access.Create()
