I'm looking for a way to order my results based on the actual time. In my table yo can see values like:
1,23:45
2,9:45
3,27:43
When I do a query I would like to know how to order them based on their actual 24 hour time.
Ex:
3,3:43
2,9:45
1,23:45
Notice how it changes 27:43 to 3:43, and creates the order.
Where I am using it, in this query:
SELECT *,COALESCE(ADDTIME(s.`departure_time`,SEC_TO_TIME(rt.delay)),s.`departure_time`) as `rt_time` FROM `stop_times` s INNER JOIN `trips` t ON s.`trip_id` = t.`trip_id` INNER JOIN `stops` st ON st.`stop_id` = s.`stop_id` INNER JOIN `routes` r ON r.`route_id` = t.`route_id` LEFT JOIN `rt_trips` rt ON t.`trip_id` = rt.`trip_id` where (s.`stop_id` = 'CB900') and ( ( s.`departure_time` >= '00:50' and s.`departure_time` <= '05:50') OR ( s.`departure_time` >= '24:50' and s.`departure_time` <= '29:50') ) and (s.`pickup_type` = '0') and (t.`service_id` IN ('removed to make it easier')) HAVING (`rt_time` BETWEEN '01:50' and '05:50' ) ) OR ( `rt_time` BETWEEN '25:50' and '29:50' ) ORDER BY `order` ASC
Explanation:
Information is a transit schedule, that may go forward onto the next day which may be a saturday. So, times may become 25:50, where that means 1:50 the next day.
Thanks

Hmmm, if you just want to get a value between 0 and 24 hours, then I would do:
select concat(mod(substring_index(time_column, ':', 1) + 0, 24), ':',
substring_index(time_column, ':', -1)
)
Try this function on the time_column
concat(mod(substr(time_column,1,INSTR(time_column, ':')-1),24)
,substr(time_column,INSTR(time_column, ':'),3)
)
You might need to cast date to string to integer, do the maths, and again cast it to time. But the fiddle version seems to work properly on varchar to integer conversion. Check this

I have the query
SELECT g.f_id as f_code
, ss.f_name as f_storage
, g.f_name as f_goods
, g.f_scancode
, s.f_price
, SUM(s.f_qty*s.f_type) as f_qty
, SUM(s.f_qty*s.f_type)*g.f_saleprice as f_totalsale
FROM a_store s
JOIN c_goods g
ON g.f_id = s.f_goods
JOIN c_storages ss
ON ss.f_id = s.f_store
JOIN a_header h
ON h.f_id = s.f_document
WHERE h.f_date <= '2020-06-22'
AND h.f_state = 1
GROUP
BY g.f_id
, ss.f_name
, g.f_name
, g.f_scancode
, s.f_price
HAVING SUM(s.f_qty*s.f_type) <> 0
ORDER
BY SUM(s.f_qty*s.f_type) asc
Every time this query returns different result and different rows count without the changes in the database. I cant understand, why.
I was change the version of mysql from 5.7 to 8.0 and problem was gone. Why it worked wrong on version 5.7 remains a mystery.
I have the following query:
select sie.invoicedate sie_invoicedate
, sie.Silitem sle_item
, sie.Silitemcode sle_itemcode
, sie.Silitemdescription sle_itemdescription
, sie.Silnetprice sle_netprice
, sie.Silquantity sle_quantity
, sie.Silunitprice sle_unitprice
, ctr.ctr_code ctr_code
, ctr.ctr_name ctr_name
, ctr.parent_code parent_code
, ctr.parent_name parent_name
, gdlsn.ssrserialnumber serialnumber
from SalesInvoicesExploded sie
join customers#inmemorystorage ctr
on ctr.ctr_id = sie.invoiceto
join GoodsDeliveryLineSerialNumbers gdlsn
on gdlsn.salesorderlineid = sie.silid
where sie.invoicedate >= '2016-01-01'
and sie.invoicedate < '2016-01-03'
order
by sie.invoicedate
How can I get the serial numbers only from the date range? In the debugger I see a lot of requests to Exact Online.
For now, there isn't a very good filter possibility to get the result you want.
The problem is that there is no way to perform the gdlsn.salesorderlineid = sie.silid filter on the data set unless the data sets have been fetched from the other side.
Only specific filters are executed server-side (like your invoicedate >= '2016-01-01'). This is quite a hard nut to crack from the program side.
It would work if you can specify a filter that can be determined on beforehand, like that the date in GoodsDeliveryLineSerialNumbers.Created always comes after the invoicedate. It would mean a significant performance improvement if you can narrow down the set based on that date.
I suggest to use something like this, if possible:
select sie.invoicedate sie_invoicedate
, sie.Silitem sle_item
, sie.Silitemcode sle_itemcode
, sie.Silitemdescription sle_itemdescription
, sie.Silnetprice sle_netprice
, sie.Silquantity sle_quantity
, sie.Silunitprice sle_unitprice
, ctr.ctr_code ctr_code
, ctr.ctr_name ctr_name
, ctr.parent_code parent_code
, ctr.parent_name parent_name
, gdlsn.ssrserialnumber serialnumber
from SalesInvoicesExploded sie
join customers#inmemorystorage ctr
on ctr.ctr_id = sie.invoiceto
join GoodsDeliveryLineSerialNumbers gdlsn
on gdlsn.salesorderlineid = sie.silid
where sie.invoicedate >= '2016-01-01'
and sie.invoicedate < '2016-01-03'
-- add the following line, use a date that for sure will yield the rows:
and gdlsn.created >= '2015-12-01'
--
order
by sie.invoicedate
My task is to get the records between 2fromdate and todate(given as a input parameters).
i am not able to use between operator for 2 input parameters...
My query as follows...
DELIMITER $$
CREATE DEFINER=`testrunner`#`%` PROCEDURE `usp_GetAllTranasactions`(pFromDate nvarchar(30),pToDate nvarchar(30),pstatus int)
BEGIN
select
ST.UserID,U.Username,
ST.SubscriptionID,
ST.DateOfSubscription,
SM.SubType,
SM.Details,
ST.Amount,
ST.EndDate,
ST.Status
from tr_t_subscriptiontransactions ST
Join tr_m_users U on U.UserID=ST.UserID
join tr_m_subscription SM on SM.SubscriptionID=ST.SubscriptionID
where **ST.DateOfSubscription between (pFromDate and pToDate) and ST.EndDate
between(pFromDate and pToDate) and ST.Status=pstatus;**
END if;
END
here i don't know how to use between parameters..plz help me..i want to retrive record between fromdate and todate..hope u understand..
Let us assume you want all transactions for the month of June 2014
In your user interface the parameter values are:
from_date = 2014-06-01
to_date = 2014-06-30
But you will evaluate against a transaction date & time. How do you ensure that absolutely every transactions on June 30 - right up to midnight - is included in the results?
Here is how: use 2014-07-01 instead of 2014-06-30, and here is what the query would look like - which does NOT use between!
SELECT
ST.UserID
, U.Username
, ST.SubscriptionID
, ST.DateOfSubscription
, SM.SubType
, SM.Details
, ST.Amount
, ST.EndDate
, ST.Status
FROM tr_t_subscriptiontransactions ST
JOIN tr_m_users U
ON U.UserID = ST.UserID
JOIN tr_m_subscription SM
ON SM.SubscriptionID = ST.SubscriptionID
WHERE (ST.DateOfSubscription >= pFromDate AND ST.DateOfSubscription < pToDate + 1)
AND (ST.EndDate >= pFromDate AND ST.EndDate < pToDate + 1)
AND ST.Status = pstatus
;
AVOID between for date ranges because it INCLUDES both the lower and upper boundary values.
... equivalent to the expression (min <= expr AND expr <= max)
http://dev.mysql.com/doc/refman/5.0/en/comparison-operators.html#operator_between
What this can lead to is an "anti-pattern" which look like this:
where dt_field between '2014-06-01 00:00:00' and '2014-06-30 23:59:59'
but there are time units smaller than one second, so that approach is imperfect. Don't attempt to overcome the deficiencies of between by adjusting the upper value this way. The simple and more accurate approach is to use >= and < adjusting the upper value by one whole time unit (usually the next day).
I have a multi-table SQL query.
My need is: The query should I generate a single line by 'etablissement_id' ... and all information that I want to be back in the same query.
The problem is that this query is currently on a table where "establishment" may have "multiple photos" and suddenly, my query I currently generates several lines for the same id...
I want the following statement - LEFT JOINetablissementContenuMultimediaON etablissement.etablissement_id = etablissementContenuMultimedia.etablissementContenuMultimedia_etablissementId - only a single multimedia content is displayed. Is it possible to do this in the query below?
Here is the generated query.
SELECT DISTINCT `etablissement`. * , `etablissementContenuMultimedia`. * , `misEnAvant`. * , `quartier`. *
FROM `etablissement`
LEFT JOIN `etablissementContenuMultimedia` ON etablissement.etablissement_id = etablissementContenuMultimedia.etablissementContenuMultimedia_etablissementId
LEFT JOIN `misEnAvant` ON misEnAvant.misEnAvant_etablissementId = etablissement.etablissement_id
LEFT JOIN `quartier` ON quartier_id = etablissement_quartierId
WHERE (
misEnAvant_typeMisEnAvantId =1
AND (
misEnAvant_dateDebut <= CURRENT_DATE
AND CURRENT_DATE <= misEnAvant_dateFin
)
)
AND (
etablissement_isActive =1
)
ORDER BY `etablissement`.`etablissement_id` ASC
LIMIT 0 , 30
Here is the code used ZF
public function find (){
$db = Zend_Db_Table::getDefaultAdapter();
$oSelect = $db->select();
$oSelect->distinct()
->from('etablissement')
->joinLeft('etablissementContenuMultimedia', 'etablissement.etablissement_id = etablissementContenuMultimedia.etablissementContenuMultimedia_etablissementId')
->joinLeft('misEnAvant', 'misEnAvant.misEnAvant_etablissementId = etablissement.etablissement_id')
->joinLeft('quartier', 'quartier_id = etablissement_quartierId ')
->where ('misEnAvant_typeMisEnAvantId = 1 AND (misEnAvant_dateDebut <= CURRENT_DATE AND CURRENT_DATE <= misEnAvant_dateFin) ')
->where ('etablissement_isActive = 1')
->order(new Zend_Db_Expr('RAND()'));
$zSql = $oSelect->__toString();
if(isset($_GET['debug']) AND $_GET['debug'] == 1)
echo $zSql ;
//die();
$oResultEtablissement = $db->fetchAll($oSelect);
return $oResultEtablissement ;
}
Can you help me?
Sincerely,
If you are looking to have only one of the media displayed out of many regardless of which it may be then you can just add a limit to the query? After that you can tweak the query for ASCending or DESCending perhaps?
Is this query supposed to have images (or image as it were) for one establishment, or one image each for each active establishment? I see you have a limit 0,30 which means you're likely paginating....
If the result you want is a search for only one establishment, and the first image it comes to would work fine .. just use "limit 1" and you'll only get one result.
I took the time to redo the whole model of the database ... and now it works. There was no solution for a system as flawed
How can I group a query result by a field that is not saved in the database.
For example I want to group the result by duration which is came from subtraction of start time and end time.
here is how i find out the duration
date1= $row_TicketRS['CloseDate'];
$date2 = $row_TicketRS['OpenDate'];
$diff = abs(strtotime($date2) - strtotime($date1));
$days = floor(($diff - $years * 365*60*60*24 - $months*30*60*60*24)/ (60*60*24));
if ( $days > 0)
{
$time1 = $row_TicketRS['OpenTime'];
$time2= $row_TicketRS['CloseTime'];
$t1=($time1);
$t2=($time2);
$end=('14:30');
$start=('07:30');
$n = $end- $t1;
$n2 = $t2- $start;
$Hours2 = floor(($n+$n2)+(($days-1)*7));
echo $Hours2.' Hours';
but know i do not know how to add it to the query
here is my query
$strQuery = "SELECT count(`ticket`.TicketID) as TotOutput, department.`DeptName` FROM `ticket`, `user`, department where ticket.OwnerID = user.EmpNo and user.`DepartmentID` = department.`DepartmentID` and OpenDate between'".$DateFrom."' And '".$DateTo."'"
It'd be better to have details, but a derived table/inline view would allow you to group by a computed value:
SELECT x.duration,
COUNT(*)
FROM (SELECT t.col,
t.end_time - t.start_time AS duration
FROM YOUR_TABLE t) x
GROUP BY x.duration
How about adding that computed value to the query with an alias like this:
SELECT some_fields, end - start AS duration FROM table ORDER BY duration
dont put alias for hidden column , use directly
exmaple:
SELECT id, FLOOR(value/100)
FROM tbl_name
GROUP BY id, FLOOR(value/100);
Reference
MySQL permits expressions in GROUP BY
clauses, so the alias is unnecessary:
