Hi I am creating basic form in Visual Studio 2012 Express. I am using Microsoft Access 2012 as database. My problem is when I press submit button I nothing happens.
Syntax error in INSERT INTO statement.
System.Data.OleDb.OleDbErrorCollection
My code is given below. Please help me to resolve this issue.

string conString = #"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\admin\Desktop\del\SHAFI\db.accdb";
OleDbConnection con = new OleDbConnection(conString);
OleDbCommand cmd = con.CreateCommand();
string text = "INSERT INTO TEST (Number, Amount) VALUES (?, ?)";
cmd.CommandText = text;
try
{
con.Open();
cmd.Parameters.AddWithValue("#Number", txtAmount.Text);
cmd.Parameters.AddWithValue("#Amount", txtOrder.Text);
cmd.ExecuteNonQuery();
}
catch (OleDbException ex)
{
txtAmount.Text = "Sorry";
Response.Write(ex.Message.ToString() + "<br />" + ex.Errors.GetType());
}
}

Answer 1

Your code is correct, apart from the lacking of using statement around disposable objects, but the real problem is the word NUMBER. It is a reserved keyword for MSAccess.
Use it enclosed in square brackets.
string text = "INSERT INTO TEST ([Number], Amount) VALUES (?, ?)";
However, if it is still possible, I really suggest you to change that column name. This problem will become very annoying.
protected void Button1_Click(object sender, EventArgs e)
{
string conString = #"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\admin\Desktop\del\SHAFI\db.accdb";
using(OleDbConnection con = new OleDbConnection(conString))
using(OleDbCommand cmd = con.CreateCommand())
{
string text = "INSERT INTO TEST ([Number], Amount) VALUES (?, ?)";
cmd.CommandText = text;
try
{
con.Open();
cmd.Parameters.AddWithValue("#Number", txtAmount.Text);
cmd.Parameters.AddWithValue("#Amount", txtOrder.Text);
cmd.ExecuteNonQuery();
}
catch (OleDbException ex)
{
txtAmount.Text = "Sorry";
Response.Write(ex.Message.ToString() + "<br />" + ex.Errors.GetType());
}
}

Answer 2

OleDbCommand does not support named parameters. You have to add the parameters in the order you want them.
//Code above
con.Open();
cmd.Parameters.Add(txtAmount.Text);
cmd.Parameters.Add(txtOrder.Text);
cmd.ExecuteNonQuery();
//Code below

You are using #Number and #Amount variables for Number and Amount but not writing these values in query.
? used in java not in asp.net(c#). so you are mixing these two.
protected void Button1_Click(object sender, EventArgs e)
{
string conString = #"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\admin\Desktop\del\SHAFI\db.accdb";
OleDbConnection con = new OleDbConnection(conString);
OleDbCommand cmd = con.CreateCommand();
string text = "INSERT INTO TEST (Number, Amount) VALUES (#Number, #Amount)";
cmd.CommandText = text;
try
{
con.Open();
cmd.Parameters.AddWithValue("#Number", txtAmount.Text);
cmd.Parameters.AddWithValue("#Amount", txtOrder.Text);
cmd.ExecuteNonQuery();
}
catch (OleDbException ex)
{
txtAmount.Text = "Sorry";
Response.Write(ex.Message.ToString() + "<br />" + ex.Errors.GetType());
}
}

Answer 4

You should use:
string text = "INSERT INTO TEST (Number, Amount) VALUES (#Number, #Amount)";
instead of:
INSERT INTO TEST (Number, Amount) VALUES (?, ?)
