Question

Hello friend how can I perform Bulk insert into MDB from Dataset. till now I have done something like this

string InsertBulkQry = "INSERT INTO Table1 SELECT * FROM table IN "       

  +MYDs.Tables[0];

I am using C# and VS 2005

Or is there any other way to update Ms Access table Faster with multiple records Thanks All

Answer 1

Yes it is possible. More Info : INSERT INTO Statement (Microsoft Access SQL)

var cmdText = "INSERT INTO Table1 SELECT * FROM Table2";
var command = new OleDbCommand(cmdText, connection);
command.ExecuteNonQuery();

Not tested, it should work. Or you can create a query in Access and Execute it from C# code.

Answer 2

This should work:

using System.Runtime.InteropServices;
using Access = Microsoft.Office.Interop.Access;

namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            var access = new Access.Application();
            access.OpenCurrentDatabase(@"C:\whatever.mdb");
            access.DoCmd.RunSQL("INSERT INTO Table1 SELECT * FROM Table2");
            access.CloseCurrentDatabase();

            Marshal.ReleaseComObject(access);
        }
    }
}
