when a table contains some fields which is varchar type and with a size more than 65536, using SQLiteCommandBuilder.GetInsertCommand() method will trigger errors like this:
------------------------------------------------------------------
System.ArgumentException: Value was either too large or too small for an Int16.Couldn't store <65536> in NumericPrecision Column.  Expected type is Int16. ---> System.OverflowException: Value was either too large or too small for an Int16.

codes are:
            string sql = string.Format("select * from tableName");
            SQLiteCommand cmd = conn.CreateCommand();
            cmd.CommandText = sql;
            SQLiteDataAdapter da = new SQLiteDataAdapter(cmd);
            SQLiteCommandBuilder cb = new SQLiteCommandBuilder(da);
            da.InsertCommand = cb.GetInsertCommand(); //==>raise error here
            da.DeleteCommand = cb.GetDeleteCommand();
