Question

我试图一次在MS Access中插入多个记录，但它说

在SQL语句结束后找到的字符。

如何一次插入所有记录，这是我的代码。

DataTable中的示例记录;

DataTable dt = new DataTable();
            dt.Clear();
            dt.Columns.Add("STORE_NAM1");
            dt.Columns.Add("STORE_ADD1");
            dt.Columns.Add("STORE_ADD2");
            dt.Columns.Add("PHONE");
            dt.Columns.Add("FAX");
            dt.Columns.Add("ABN_ACN_NO");
            dt.Columns.Add("EMAIL");
            dt.Columns.Add("WEB");
            object[] o = { "Qadeer", "Qadeer", "Qadeer", "Qadeer", "Qadeer", "Qadeer", "Qadeer", "Qadeer" };
            dt.Rows.Add(o);
            object[] o2 = { "Qadeer", "Qadeer", "Qadeer", "Qadeer", "Qadeer", "Qadeer", "Qadeer", "Qadeer" };
            dt.Rows.Add(o2);
            object[] o3 = { "Qadeer", "Qadeer", "Qadeer", "Qadeer", "Qadeer", "Qadeer", "Qadeer", "Qadeer" };
            dt.Rows.Add(o3);

这是插入..

    using (OleDbConnection con = new OleDbConnection(connectionAccess))
    {


        List<string> Rows = new List<string>();
        string sCommand = "";
        foreach (DataRow row in dt.Rows)
        {
            sCommand += "insert into store (STORE_NAM1, STORE_ADD1, STORE_ADD2, PHONE, FAX, ABN_ACN_NO, EMAIL, WEB) values ('"
                + row["STORE_NAM1"].ToString() + "', '" 
                + row["STORE_ADD1"].ToString() + "', '" 
                + row["STORE_ADD2"].ToString() + "', '" 
                + row["PHONE"].ToString() + "', '" 
                + row["FAX"].ToString() + "', '" 
                + row["ABN_ACN_NO"].ToString() + "', '" 
                + row["EMAIL"].ToString() + "', '" 
                + row["WEB"].ToString() + "');";

//if I hard code values, this works fine with one insert
//sCommand = "insert into store(STORE_NAM1, STORE_ADD1, STORE_ADD2, PHONE, FAX, ABN_ACN_NO, EMAIL, WEB) values ('Qadeer', 'Qadeer', 'Qadeer', 'Qadeer', 'Qadeer', 'Qadeer', 'Qadeer', 'Qadeer');";

//this does not work with multiple records
//sCommand = "insert into store(STORE_NAM1, STORE_ADD1, STORE_ADD2, PHONE, FAX, ABN_ACN_NO, EMAIL, WEB) values ('Qadeer', 'Qadeer', 'Qadeer', 'Qadeer', 'Qadeer', 'Qadeer', 'Qadeer', 'Qadeer'); insert into store(STORE_NAM1, STORE_ADD1, STORE_ADD2, PHONE, FAX, ABN_ACN_NO, EMAIL, WEB) values ('Qadeer', 'Qadeer', 'Qadeer', 'Qadeer', 'Qadeer', 'Qadeer', 'Qadeer', 'Qadeer'); insert into store(STORE_NAM1, STORE_ADD1, STORE_ADD2, PHONE, FAX, ABN_ACN_NO, EMAIL, WEB) values ('Qadeer', 'Qadeer', 'Qadeer', 'Qadeer', 'Qadeer', 'Qadeer', 'Qadeer', 'Qadeer');";


      try
        {
            using (OleDbCommand myCmd = new OleDbCommand(sCommand, con))
            {
                con.Open();
                myCmd.CommandType = CommandType.Text;
                int result = myCmd.ExecuteNonQuery();
                Console.WriteLine(result +" records inserted");
            }
        }
        catch (Exception ex)
        {

            Console.WriteLine(ex.Message);

        }

    }

我也尝试过参数化方式。

更改

sCommand += "insert...

要

sCommand = "insert...

你第一次通过循环插入字符串很好。在那之后，它变得越来越长。 Access只需要每个查询一个语句。

在c＃中一次在MS Access中插入多行
