数据集插入记录返回0，请高手帮助
我是WINFORM ACCESS数据库 没有提示任何错误，只是返回UPDATA返回0
代码如下
string cmdselect = "SELECT * FROM [base] where 0> 1 ";
string myConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source= " + System.Windows.Forms.Application.StartupPath + "\\database\\esenge.mdb " + ";User ID=admin;Jet OLEDB:Database Password=lq~b819_531~by ";
OleDbConnection conn = new OleDbConnection(myConnectionString);
conn.Open();
OleDbCommand command = conn.CreateCommand();
command.CommandText = cmdselect; //SQL命令赋值 ，以获得结构
//command.CommandType = CommandType.TableDirect;
OleDbDataAdapter adapter = new OleDbDataAdapter(command);
//adapter.SelectCommand = cmdselect;
DataSet ds = new DataSet();
adapter.Fill(ds, cmdselect);
adapter.TableMappings.Add( "base ", "base ");
DataRow dr = ds.Tables[0].NewRow(); ;
//ds.Clear();//清除该表记录，只保留结构
//DataRow dr = ds.Tables[0].NewRow();//增加新的一行；
dr[0] = nform0.Text;
dr[1] = nform1.Text;
dr[2] = nform2.Text;

//adapter.UpdateCommand = mycb.GetUpdateCommand();
OleDbCommandBuilder mycb = new OleDbCommandBuilder(adapter);
ds.Tables[0].Rows.Add(dr);//这行增加一行
adapter.Fill(ds);
MessageBox.Show(ds.Tables[0].Rows.Count.ToString() + adapter.InsertCommand.ToString());
try
{
if (adapter.Update(ds, "base ") > = 1)
{
MessageBox.Show( "成功 ");
}
else
{
MessageBox.Show( "没有成功(: ");
}
}
catch( Exception err )
{
MessageBox.Show(err.Message);
}
finally
{
//ds.Dispose();
//adapter.Dispose();
conn.Close();//这里关闭数据库了
}
