一直以爲mysql的Memony內存引擎挺好，其餘數據庫都沒有，正好有空，因此試試。html

版本：mysql-installer-community-8.0.17.0mysql

os：windows10 SSD硬盤，本機訪問sql

簡單表，一個ID字段爲主鍵，一個字符串字段數據庫

1. Memony引擎windows

單條插入10000條耗時18s，批量事務提交插入10000條耗時18s。測試

2. Myisam引擎ui

單條插入10000條耗時19s，批量事務提交插入10000條耗時19s。this

3. InnoDB引擎orm

單條插入10000條耗時40s，批量事務提交插入10000條耗時2s。htm

        private void button4_Click(object sender, EventArgs e)
        {
            //查詢
            MySqlDataAdapter da = new MySqlDataAdapter("select * from " + this.textBox1.Text, this.connstring);
            DataSet ds = new DataSet();
            da.Fill(ds, "t");
            this.dataGridView1.DataSource = ds.Tables[0].DefaultView;
        }
