How do I insert cells using INSERT INTO & SET? (Excel oledb)

Question

Updating a cell works:
    oledbConnect = new System.Data.OleDb.OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\\__\\test.xls;Extended Properties='Excel 12.0 Xml;HDR=NO;'");
    oledbConnect.Open();
    oledbCmd.Connection = oledbConnect;
    string stSheetName = "Sheet2";
    string sql;
    sql = "UPDATE [" + stSheetName + "$A1:B1] SET F1=1";
    oledbCmd.CommandText = sql;
    oledbCmd.ExecuteNonQuery();
Inserting a cell does not:
    sql = "INSERT INTO [" + stSheetName + "$A2:B2] SET F1=2'";
    oledbCmd.CommandText = sql;
    oledbCmd.ExecuteNonQuery();
I understand that inserting will add a new row ... but this doesn't work either.
    sql = "INSERT INTO [" + stSheetName + "$] SET F1=3";
    oledbCmd.CommandText = sql;
    oledbCmd.ExecuteNonQuery();

Hi hbs67,
No, we can't use Insert into with Set, it's the basic syntax in SQL statement. Give the worksheet a header row, then use Insert into or Update syntax with the field name.
