添加一组数据时，提示insert into 语法错误

        //数据库连接
        string connstr = "Provider=Microsoft.Jet.OleDb.4.0;";
        connstr += @"Data Source=D:\Merger201503016caohuan\GEARCNC.mdb";//创建连接对象

        OleDbConnection tempconn = new OleDbConnection(connstr);

        tempconn.Open();

        string str="select * from WorkPieceData";
        OleDbCommand acommand = new OleDbCommand(str , tempconn);
        OleDbDataAdapter WorkPieceDataDA = new OleDbDataAdapter();
        DataSet ds = new DataSet();
        WorkPieceDataDA.SelectCommand = acommand;
        WorkPieceDataDA.Fill(ds, "WorkPieceData");
        tempconn.Close();
       //新建一行
        DataRow dr = ds.Tables["WorkPieceData"].NewRow(); 

        //为各字段赋值
        dr["齿数"] = ChiShu.Text;
        dr["法面模数"] = BiaoZhunMoShu.Text;


        ds.Tables["WorkPieceData"].Rows.Add(dr);//将新行添加到表中

        OleDbCommandBuilder builder = new OleDbCommandBuilder(WorkPieceDataDA);
        tempconn.Open();
        WorkPieceDataDA.Update(ds,"WorkPieceData");
        tempconn.Close();

检查下主键是否重复，不许为空的字段是否指定值，等等。

主键你打开access，表中画一个钥匙的字段就是。

我已经解决了，谢谢，我只是在ACCESS数据库中的字段改为了“必需”，我也不知道为什么

肯定是表中的字段约束了的原因。
