Question

I want to write a simple code line that will delete all the datarows in a certain Table.
(Working with c# and MS Access 2010)
The table contains about 1000 rows, 10 columns, and it gets a bit slow.

This code does the job:

  connStr = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=E:\Words\shinunonDB.accdb;Persist Security Info=False;";

  OleDbConnection Conn = new OleDbConnection();
  Conn.ConnectionString = connStr;
  sql = "select * from Heb";
  Conn.Open();
  OleDbDataAdapter da = new OleDbDataAdapter(sql, Conn);
  DataSet ds = new DataSet();
  OleDbCommandBuilder cb = new OleDbCommandBuilder(da);

  da.Fill(ds, "Heb");
  foreach (DataRow dRow in ds.Tables["heb"].Rows)
  {
      dRow.Delete();
  }
  da.Update(ds, "heb");

But I guess there might be a shorter and more efficient way to do it.

Thank you guys.

Yes, there is. Just use a SQL command:

delete from Heb;

You can issue a SQL command on a OleDbConnection. Something like this:

OleDbCommand ac = new OleDbCommand("delete from Heb",Conn);
ac.ExecuteNonQuery();
