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);
}
