Question

我想通过C＃代码将我的数据从OdbcConnection复制到SqlStatment。通过一个按钮，我想这样做...... 我对c＃的专家不多，但只是一点点编程，有些人可以添加/编辑一些代码我们的声明/帮助，这样我就可以完成我的程序了。

我通过这段代码但数据没有获取......

public partial class _Default : System.Web.UI.Page
{
private OdbcConnection cn;
private SqlCommand DB_Cmd;
private SqlConnection DB_cn;
public const string DbConStr = "Data Source=172.16.4.8;Initial Catalog=anDb;User ID=sa; Password= ;";
private OdbcCommand Jda_Cmd;
//private long Jda_Order_no;
public const string JdaConStr = "DSN=Imports_Img;UserID=user2;Password=pass2;Data Source=172.16.4.5;Transport Product=Client Access;SSL=DEFAULT;DEFAULT COLLECTION='BINDAWOOD'";
//private string sku;

}
protected void Button1_Click(object sender, EventArgs e)
{
    this.cn = new OdbcConnection();
    this.Jda_Cmd = new OdbcCommand();
    this.Jda_Cmd.Connection = this.cn;
    this.cn.ConnectionString = "DSN=Imports_Img;UserID=JUNAID;Password=PAKIKARA19;Data Source=172.16.4.5;Transport Product=Client Access;SSL=DEFAULT;DEFAULT COLLECTION='BINDAWOOD'";
    string str = ("SELECT ibhand FROM MM410LIB.INVBAL WHERE INUMBR = 79610 AND ISTORE=14");
    this.Jda_Cmd.CommandText = str;
    {
        this.cn.Open();

        OdbcDataReader reader2 = this.Jda_Cmd.ExecuteReader();
        //connection2.Open();
        while (reader2.Read())
        {
            this.DB_Cmd = new SqlCommand();
            this.DB_Cmd.Connection = this.DB_cn;
            SqlConnection connection2 = new SqlConnection();
            //SqlCommand db_cn = new SqlCommand ("insert into invbaldb ('sku') values ('" + reader2[0] + "')", connection2);

            //SqlCommand db_cn = new SqlCommand("insert into invbaldb (sku) values ('" + reader2[0].ToString() + "')", connection2);

            SqlCommand DB_cn = new SqlCommand("insert into invbaldb (sku) values (@sku)", connection2);
            DB_cn.Parameters.AddWithValue("@sku", reader2[0].ToString());

            //SqlCommand command2 = new SqlCommand("insert into invbaldb ('sku') values ('" + reader2[0] + "')", connection2);
            //DB_cn.ExecuteNonQuery();
            DB_cn.ExecuteNonQuery();
        }
        reader2.Close();
        //connection2.Close();
    }
}
}

如果表invbaldb中的目标字段名为sku，那么您不应该在该名称周围加上单引号，因为这样会被解释为文字字符串

  SqlCommand db_cn = new SqlCommand ("insert into invbaldb (sku) values ('" + 
                                      reader2[0].ToString() + "')", connection2);

还要考虑使用参数化查询而不是字符串连接。

  SqlCommand db_cn = new SqlCommand ("insert into invbaldb (sku) values (@sku)", connection2);
  db_cn.Parameters.AddWithValue("@sku", reader[0].ToString());

编辑如果目标字段是数字，则应相应地键入参数

  db_cn.Parameters.AddWithValue("@sku", Convert.ToInt32(reader[0].ToString()));

当然这意味着输入值可以转换为整数值
