MySQL查询 - 按日期范围内的日期和组字段排序

Question

我想按日期和代码ASC在同一天订购以下查询：Ex。 所有在特定日期（按日期时间排序）和在同一天按代码订购的门票。

我已尝试过group by但它不起作用。

这是我的查询;

SELECT 
      tck_NRicevuta as ticket,
      tck_dataOUT AS date_out,
      tck_ID_tariffa AS code,
      park_ticket.tck_importo AS ToTal 
  FROM
      park_ticket 
 WHERE
      tck_flaguscita =  'U'
ORDER BY
      date_out, code

查询结果：错误!! - 我希望按日期时间排序，然后在同一天按代码排序

Answer 1

您只能通过在date_out上使用date()按日期订购结果

SELECT tck_NRicevuta as ticket,
    tck_dataOUT AS date_out,
    tck_ID_tariffa AS code,
    park_ticket.tck_importo AS ToTal 
FROM park_ticket 
WHERE tck_flaguscita =  'U' 
ORDER BY date(date_out),code
