【问题描述】：

我正在尝试使用 C# 将数据插入 Access 2007，我从 *** 获得了一些代码，它确实有助于将数据插入到单个表中，但我试图将数据插入到两个具有一对多关系的表中，并且代码将运行，它没有争吵或错误，但是当我单击插入按钮时，会有一些消息框告诉我由于插入语句中的语法错误而失败。有人可以解决这个问题吗？ 其他我在form2上有一些按钮，例如我们更新，搜索，当我单击此按钮中的一个时，窗口将打开n如果我单击按钮10次将不会关闭前一个窗口，这将是十个窗口....请对这种语言不熟悉，我需要一些代码方面的帮助。

这是我的代码...

namespace WindowsFormsApplication1

    public partial class Form2 : Form
    
        public Form2()
        
            InitializeComponent();
        

    private void button2_Click(object sender, EventArgs e)
    
        Form3 f3 = new Form3();
        f3.ShowDialog();
    

    private void button3_Click(object sender, EventArgs e)
    
        Form4 f4 = new Form4();
        f4.ShowDialog();
    


    private void button4_Click(object sender, EventArgs e)
    
        Form1 f1 = new Form1();
        f1.Show();
    


    private void button1_Click(object sender, EventArgs e)
    
        System.Data.OleDb.OleDbConnection conn = new System.Data.OleDb.OleDbConnection();
        conn.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;" +
        @"Data source= C:\Users\user\Desktop\crt_db.accdb";
        try
        
            conn.Open();
            String Name = txtName.Text.ToString();

            String AR = txtAr.Text.ToString();
            String Wereda = txtWereda.Text.ToString();
            String Kebele = txtKebele.Text.ToString();
            String House_No = txtHouse.Text.ToString();
            String P_O_BOX = txtPobox.Text.ToString();
            String Tel = txtTel.Text.ToString();
            String Fax = txtFax.Text.ToString();
            String Email = txtEmail.Text.ToString();
            String Item = txtItem.Text.ToString();
            String Dep = txtDep.Text.ToString();
            String Remark = txtRemark.Text.ToString();

            String Type = txtType.Text.ToString();
            String Brand = txtBrand.Text.ToString();
            String License_No = txtlicense.Text.ToString();
            String Date_issued = txtDate.Text.ToString();
            String my_querry = "INSERT INTO crtPro(Name,AR,Wereda,Kebele,House_No,P_O_Box,Tel,Fax,Email,Item,Dep,Status,Remark,)VALUES('" + Name + "','" + AR + "','" + Wereda + "','" + Kebele + "','" + House_No + "','" + P_O_BOX + "','" + Tel + "','" + Fax + "','" + Email + "','" + Item + "','" + Dep + "','" + Remark + "')" +
                      "AND INSERT INTO crtItemLicense (" +
                      "Type,Brand,License_No,Date_issued) VALUES('" + Type + "','" + Brand + "','" + License_No + "','" + Date_issued + "') ";

            OleDbCommand cmd = new OleDbCommand(my_querry, conn);
            cmd.ExecuteNonQuery();

            MessageBox.Show("Data saved successfuly...!");
        
        catch (Exception ex)
        
            MessageBox.Show("Failed due to" + ex.Message);
        
        finally
        
            conn.Close();

显然与 SQL 不同，你不能在一个语句中组合插入 - 有办法绕过它 (***.com/questions/62504/…) 但如果我是你，我会让它们成为 2 个单独的命令

确定 NDJ，我正在尝试关注你，但正如我告诉你的那样，当我尝试使用 ';' 时出现错误或者只是把这段代码放在一行 String my_query = "INSERT INTO crtPro(Name,AR,Wereda,Kebele,House_No,P_O_Box,Tel,Fax,Email,Item,Dep,Status,Rema‌​‌​rk)VALUES('" + 姓名 + "','" + AR + "','" + Wereda + "','" + Kebele + "','" + House_No + "','" + P_O_BOX + "','" + 电话+ "','" + 传真 + "','" + 电子邮件 + "','" + 项目 + "','" + Dep + "','" + 备注 + "')"; "INSERT INTO crtItemLicense (Type,Brand,License_No,Date_issued) VALUES('" + Type + "','" + Brand + "','" + License_No + "','" + Date_issued + "')";

【参考方案1】：

在您的第一个插入语句中，Remark 后有一个“，”，我相信这可能会导致无效的语法错误。

String my_querry = "INSERT INTO crtPro(Name,AR,Wereda,Kebele,House_No,P_O_Box,Tel,Fax,Email,Item,Dep,Status,Remark**,**

【讨论】：

嗯，你是对的，我把无用的“，”在评论之后谢谢你，你能帮我解决一下 1 小时前发布的休息时间，再次感谢 NDJ :)

【参考方案2】：

//这会将数据添加到多个表中。

        Form4 f4 = new Form4();
        f4.ShowDialog();
