sql请求检索每天的最大，最小第一个和最后一个记录

Question

I would like to get the min, and max, the first and the last record in my database mysql. I'm looking for a high-performance query that takes no more than 15 minutes.

I have tested :

SELECT
  MIN(low),
  MAX(high),
  CONCAT(YEAR(date), "-", WEEK(date)) AS myweek,
  (select open from prices m where WEEK(m.date)=WEEK(prices.date) order by date LIMIT 1) as first_open,
  (select close from prices m where WEEK(m.date)=WEEK(prices.date) order by date desc LIMIT 1) as last_close
FROM prices
GROUP BY myweek
ORDER BY date;

But i have a error :

Erreur dans la requête (1055): Expression #4 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'siteinfo.prices.date' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

I can not correct this error because I do not have access to conf files and I do not have user superadmin.

I have tested too :

select 
DATE_FORMAT(date, "%Y" "%m" "%d") as datetime, 
(select open from prices m where m.date like CONCAT(YEAR(datetime), "-[0]", Month(datetime), "-[0]", DAY(datetime), "%") and fk_cryptoid = 'f2a0ba90-93df-11e8-af1b-5968de90d63b'  order by date ASC LIMIT 1) as open,
(select close from prices m where m.date like CONCAT(YEAR(datetime), "-[0]", Month(datetime), "-[0]", DAY(datetime), "%") and fk_cryptoid = 'f2a0ba90-93df-11e8-af1b-5968de90d63b'  order by date DESC LIMIT 1) as close,
min(low) as low, 
max(high) as high 
from prices
where fk_cryptoid = 'f2a0ba90-93df-11e8-af1b-5968de90d63b' 
 GROUP BY datetime;

but CONCAT() does not return the day and the month with a zero in addition: 2018-1-2 and not 2018-01-02. Then this request takes too much time.

Model for table Prices :

id  int(11) Incrément automatique    
close   double NULL  
open    double NULL  
low double NULL  
high    double NULL  
date    datetime NULL    
createdAt   datetime     
updatedAt   datetime     
fk_cryptoid char(36) NULL

If it works for you, then I would suggest the group_concat() / substring_index() trick:

SELECT MIN(low), MAX(high),
       CONCAT(YEAR(date), '-', WEEK(date)) AS myweek,
       SUBSTRING_INDEX(GROUP_CONCAT(open ORDER BY date), ',', 1) as first_open,
       SUBSTRING_INDEX(GROUP_CONCAT(close ORDER BY date DESC), ',', 1) as last_close
FROM prices
GROUP BY myweek
ORDER BY date;

Notes:

• This first_open and last_close columns will be strings.
• The assumption is that open and close do not have commas. If they do, use a different separator.
• GROUP_CONCAT() has a default internal limit of about 1,000 bytes. You can adjust that using server parameters.
