查询速度超快的数据库,自己测试过插入1000条数据,不用1秒时间!

演示代码:
using System;
using System.Collections.Generic;
using System.Text;
using System.Data;
using System.Data.Common;
using System.Data.SQLite;
using System.IO;
using System.Diagnostics;
namespace Sqlite
{
class Program
{
static void Main(string[] args)
{
File.Delete("test1.db3");
SQLiteConnection.CreateFile("d:\\test1.db3");
DbProviderFactory factory = SQLiteFactory.Instance;
using (DbConnection conn = factory.CreateConnection())
{
// 连接数据库
conn.ConnectionString = "Data Source=d:\\test1.db3";
conn.Open();
// 创建数据表
string sql = "create table [test1] ([id] INTEGER PRIMARY KEY, [s] TEXT COLLATE NOCASE)";
DbCommand cmd = conn.CreateCommand();
cmd.Connection = conn;
cmd.CommandText = sql;
cmd.ExecuteNonQuery();
// 添加参数
cmd.Parameters.Add(cmd.CreateParameter());
// 开始计时
Stopwatch watch = new Stopwatch();
watch.Start();
DbTransaction trans = conn.BeginTransaction(); // <-------------------
try
{
// 连续插入1000条记录
for (int i = 0; i < 1000; i++)
{
cmd.CommandText = "insert into [test1] ([s]) values (?)";
cmd.Parameters[0].Value = i.ToString();
cmd.ExecuteNonQuery();
}
trans.Commit(); // <-------------------
}
catch
{
trans.Rollback(); // <-------------------
throw; // <-------------------
}
// 停止计时
watch.Stop();
Console.WriteLine(watch.Elapsed);
}
}
}
