  • Hello mukesh bera,


    Welcome to the MSDN Forum!

    According to your description, you mean that you can see the new record in the database, but once you close the database, the new added has removed from the database, right?

    And more, have you met some errors or exceptions? If so, could you show us the error messages? And note that your connection object isn't closed.

    I am looking forward to hearing from you!


    Good day,

  • Hi mukesh,


    According to your code, why do you use DataAdapter to excute your command?

    I think you can use OleDbCommand to insert you records directly(http://msdn.microsoft.com/en-us/library/system.data.oledb.oledbcommand.aspx)

    OleDbCommand cmd = conn.CreateCommand();
    Have a nice day.

  • Anyone tell me, what is wrong with that code?

    string str1 = "";
                string str2 = "";
                str1 = "Insert into Table1(id, Disease,Symptoms,Drugs,Side effects,Genes,Proteins) Values (@id, @Disease,@Symptoms,@Drugs,@Side effects,@Genes,@Proteins)";

               str2 = "Insert into Table1(Disease clr, side effects/Symptoms clr,drugs clr,genes color,proteins clr) Values ('1', '5' ,' 4' , '2 ',' 3')";

                OleDbCommand com1 = new OleDbCommand(str1, connection);
                OleDbCommand com2 = new OleDbCommand(str2, connection);
                com1.Parameters.Add("@id", OleDbType.Integer, 5);
                //com1.Parameters.Add("@id", OleDbType.VarChar, 200);

                com1.Parameters.Add("@Disease", OleDbType.VarChar, 200);
                com1.Parameters.Add("@Symptoms", OleDbType.VarChar, 200);
                com1.Parameters.Add("@Drugs", OleDbType.VarChar, 200);
                com1.Parameters.Add("@Side effects", OleDbType.VarChar, 200);
                com1.Parameters.Add("@Genes", OleDbType.VarChar, 200);
                com1.Parameters["@id"].Value = System.Convert.ToInt32(textBox1.Text.ToString());
                //com1.Parameters["@id"].Value = textBox1.Text.ToString();

                com1.Parameters["@Disease"].Value = textBox2.Text.ToString();

                com1.Parameters["@Symptoms"].Value = textBox3.Text.ToString();
                com1.Parameters["@Drugs"].Value = textBox4.Text.ToString();
                com1.Parameters["@Side effects"].Value = textBox5.Text.ToString();            
                com1.Parameters["@Genes"].Value = textBox6.Text.ToString();            
                com1.Parameters["@Proteins"].Value = textBox7.Text.ToString();
                textBox1.Text = "";
                textBox2.Text = "";
                textBox3.Text = "";
                textBox4.Text = "";
