使用transaction:
var stopwatch = new Stopwatch(); using (var cmd = new SQLiteCommand(db_con)) using (var transaction = db_con.BeginTransaction()) { stopwatch.Reset(); stopwatch.Start(); foreach (var item in sorted) { sql = string.Format("insert into db (st1, st2) values ('{0}', {1})", item.Key.Replace("'", "''"), item.Value); cmd.CommandText = sql; cmd.ExecuteNonQuery(); ++readCnt; if (++readCnt % 1000000 == 0) { Console.Write("rDumped {0} lines...", readCnt); } } Console.Write("rCommitting...."); transaction.Commit(); stopwatch.Stop(); Console.Write("rDumped {0} lines using {1} seconds...", readCnt, stopwatch.Elapsed.TotalSeconds); }
