无法使用c#windows应用程序在MS access数据库中插入数据

我曾尝试在MS access数据库中插入数据，但数据库中未添加数据，并且未给出错误

  private void btnsubmit_Click(object sender, EventArgs e)
    {

        int row = dataGridView1.RowCount;
        for (int i = 0; i < row - 1; i++)
        {
            String str = "INSERT INTO JDS_Data(job_no,order_no,Revision,DesignSpec,Engine_Type,Record_date,LE_IN_Designer,CPH_Designer,Exp_Del_Week,Action_code,Rev_Description,Ref_pattern,Name_of_mock_up,EPC_Drawing,Turbocharger_no_Type,Engine_Specific_Requirement,Draft_sketch_with_details,Air_cooler_type,Description_of_Job,SF_No,Standard,Prority_Sequence,Remark,Part_family,Modified_Date,User)  values('" + txtjobno.Text + "','" + txtorderno.Text + "','" + txtrevison.Text + "','" + txtds.Text + "','" + txtenginetype.Text + "','" + dateTimePicker1.Text + "','" + txtleindesigner.Text + "','" + txtcphdesigner.Text + "','" + txtexpweek.Text + "','" + txtactioncode.Text + "','" + txtrevdescription.Text + "','" + txtrefpatern.Text + "','" + txtmockup.Text + "','" + txtepcdwg.Text + "','" + txtturbono.Text + "','" + txtenginereq.Text + "','" + txtdraft.Text + "','" + txtaircolertype.Text + "','" + txtdespjob.Text + "','" + dataGridView1.Rows[i].Cells[0].Value.ToString() + "','" + dataGridView1.Rows[i].Cells[1].Value.ToString() + "','" + dataGridView1.Rows[i].Cells[2].Value.ToString() + "','" + txtremark.Text + "','" + dataGridView1.Rows[i].Cells[3].Value.ToString() + "','" + DateTime.Today + "','" + mdlconnection.user_name + "')";

            int dd = mdlconnection.excuteQuery(str);
            MessageBox.Show(str);
            //if (dd > 0)
            {
                MessageBox.Show("Data Saved Successfully..!!!");

            }

        }

    }   

private void btnsubmit\u单击（对象发送者，事件参数e）
{
int row=dataGridView1.RowCount；
对于（int i=0；i0）
{
MessageBox.Show（“数据保存成功..！！！”；
}
}
}   

您的语法可能不正确。使用字符串串联构造查询总是一个坏主意。使用参数化查询字符串，通过

OdbcCommand.Parameters处理内置参数值。添加（…）

您的查询在第行下方有

语法

错误使用

String str = "INSERT INTO JOB_Quality_Rating(Team,JOB_Type,Designer_Name,AUR_NO,Task_No,Sub_Function_no,Severity_Level,Checkpoints,Points_Deducted,Total_Points,Submitted_By,Submitted_Date) values('" + comboBox1.SelectedItem + "','"+comboBox7.SelectedItem+"','" + comboBox3.SelectedItem + "','" + comboBox6.SelectedItem + "','" + cmbtaskno.SelectedItem + "','" + comboBox2.SelectedItem + "','" + dataGridView1.Rows[i].Cells[0].Value.ToString() + "','" + dataGridView1.Rows[i].Cells[1].Value.ToString() + "','" + dataGridView1.Rows[i].Cells[2].Value.ToString() + "','" + txtTotal.Text + "','" + mdlconnection.user_name + "','" + dateTimePicker1.Text + "')";

而不是

String str = "INSERT INTO JOB_Quality_Rating(Team,JOB_Type,Designer_Name,AUR_NO,Task_No,Sub_Function_no,Severity_Level,Checkpoints,Points_Deducted,Total_Points,Submitted_By,Submitted_Date) values('" + comboBox1.SelectedItem + "',,'"+comboBox7.SelectedItem+"','" + comboBox3.SelectedItem + "','" + comboBox6.SelectedItem + "','" + cmbtaskno.SelectedItem + "','" + comboBox2.SelectedItem + "','" + dataGridView1.Rows[i].Cells[0].Value.ToString() + "','" + dataGridView1.Rows[i].Cells[1].Value.ToString() + "','" + dataGridView1.Rows[i].Cells[2].Value.ToString() + "','" + txtTotal.Text + "','" + mdlconnection.user_name + "','" + dateTimePicker1.Text + "')";

希望有帮助。

cyberj0g是正确的，您的语法不正确。特别是，您的值列表中缺少一个值：

…comboBox1.SelectedItem+“，”+comboBox7.选择EdItem…

。您不能以这种方式传递空值。请在此处传递NULL或从字段列表子句中删除相应字段：

…团队、设计师名称…

（以及额外的逗号或课程）。

您可以尝试以下操作- -尝试在access中手动执行查询字符串（str变量中形成的内容），以确保语法中没有错误，并在那里成功执行 -将执行语句包装在try..catch块中以获取错误详细信息

-确保连接指向正确的数据库实例

能否同时显示

mdlconnection.excuteQuery

？是否调试了代码并查看了发生的情况？是否确定连接字符串是正确的？列类型是什么？顺便问一下，您应该始终使用这种字符串连接。这种类型的字符串连接对您是开放的攻击。
