QuestionCopy DataTable into a Ms Access table Pin
Member 1464251030-Sep-20 22:31

I need to copy a DataTable inside another table (MS Access) which has the same structure. I did this:

DataTable dtBit = new DataTable(); 
dtBit.TableName= "Macchine_Bit"; 

using (OleDbCommand cmd = new OleDbCommand("SELECT * FROM [Macchine_Bit] ORDER BY [FIELD_ID]", cnn))
{
	using (OleDbDataAdapter da = new OleDbDataAdapter(cmd))
	{
		da.MissingSchemaAction = MissingSchemaAction.AddWithKey;
		da.Fill(dtBit = new DataTable());
	}
}


When I got my DataTable, I open a connection to another mdb file and try to put the contents of dtBit table into another:

cnn.ConnectionString = String.Format(myConnectionString, mdbCopyName);
cnn.Open();

using (OleDbDataAdapter a = new OleDbDataAdapter("SELECT * FROM [Macchine_Bit]", cnn))
{
	OleDbCommandBuilder cb = new OleDbCommandBuilder(a);
	a.MissingSchemaAction = MissingSchemaAction.AddWithKey;
	a.InsertCommand = cb.GetInsertCommand();
	a.DeleteCommand = cb.GetDeleteCommand();
	a.UpdateCommand = cb.GetUpdateCommand();
	a.TableMappings.Add("Macchine_Bit", "Macchine_Bit");                

	DataTable dtBit2 = new DataTable();
	a.Fill(dtBit2);

	dtBit2.Merge(dtBit);
	a.Update(dtBit2);
}


Basically no rows are written. What's wrong with my code? I got non error
