如何在特定日期選擇最大時間戳？

Question

我有date = 2013-05-08和一欄：

|timestamp

|2013-05-08 21:02:11

|2013-05-08 22:22:21

|2013-05-08 23:05:12

|2013-05-09 11:02:10

|2013-05-10 09:12:01

結果應該是：

2013-05-08 23:05:12

我怎樣才能做到這一點？

Answer 1

SELECT MAX(timestamp) 
    FROM table 
        WHERE DATE(timestamp) = '2015-05-08' 
        GROUP BY DATE(timestamp);
