This program shows how to insert data in an access database using ADO and SQL query. I have an Access 2000 database in project\bin\debug directory. My database name is mcTest.MDB. You can create your own database and copy in your project's debug directory. I am not attaching database with this code because of size problem.

I have a table 'Developer' in this database which has four columns. I am inserting values into two columns Name and Address in this code.

using System;
using System.Data;
using System.Data.OleDb;
namespace ADONETWriteQuery
{
/// <summary>
/// Summary description for Class1.
/// </summary>
class Class1
{
static void Main(string[] args)
{
string strDSN = "Provider=Microsoft.Jet.OLEDB.4.0;DataSource=c:\\mcTest.MDB"; string strSQL = "INSERT INTO Developer(Name, Address ) VALUES('NewName', 'NewAddress')" ;
// create Objects of ADOConnection and ADOCommand
OleDbConnection myConn = new OleDbConnection(strDSN);
OleDbCommand myCmd = new OleDbCommand( strSQL, myConn );
try
{
myConn.Open();
myCmd.ExecuteNonQuery();
}
catch (Exception e)
{
Console.WriteLine("Oooops. I did it again:\n{0}", e.Message);
}
finally
{
myConn.Close();
}
}
}
}
