I used SQLite. The user will pull the days from checkbox and I'll show it in data grid view but the date is recorded as day and time so I have to use like instead of in command.

```
        DataSet dataSet122;
        listBox1.Items.Clear();
        SQLiteConnection connection = new SQLiteConnection("Data Source =log.sqlite;Version=3;");
        string search = checkBoxComboBox1.Text;
        string[] array = search.Split(',');
        for (int i = 0; i < array.Length; i++)
        {
            array[i] = "'" + array[i] + "'";
        }
        string names = String.Join(",", array);
        listBox2.Items.Add(names);
        string query = "SELECT * FROM Gemkay1 WHERE ZAMAN LIKE  (" + names + ")";
        command = new SQLiteCommand(query, connection);
        connection.Open();
        adapter = new SQLiteDataAdapter(command);
        dataSet122 = new DataSet();
        adapter.Fill(dataSet122, "Gemkay1");
        dataGridViewSummary1.DataSource = dataSet122.Tables["Gemkay1"];
