I am working on a project which is running in 2 countries already. Everything was fine until we deployed the project in Nepal. The problem is they are not working with standard Gregorian calendar. They have their own calendar called Bikram Sanwant Calendar. Our existing database has DateTime/Date columns which I cannot use any more because few months in their calendar have 32 days which is not a valid date according to the Gregorian calendar. So we have thought of saving all the dates in 3 different columns like Day,Month and year. Not just that but we also have used inbuilt standard SQL DateTime Functions like DateAdd, DateDiff etc... So I will also have to write my own functions and change all the queries, Stored Procedures and Functions.
Does anyone know how to deal with this or have better idea about this issue?
Please give your input and suggestions.
Thanks in advance.
Check this php code to convert AD to BS. Hope this will help you in understanding more.
<?php
//The Vikram Samvat calendar is 56 years 8 months and 14 days ahead (in count) of the solar Gregorian calendar
//date_default_timezone_set('Asia/Kathmandu');
$date = date('Y-m-d');
$ts1 = strtotime($date);
$year1 = date('Y', $ts1) + 56;
$month1 = date('m', $ts1) + 8;
$day1 = date('d', $ts1) + 14;
if($month1 >12) {
$year1 = $year1+1;
//$remMonth = $month1-12;
$month1 = $month1-12;
}
if($day1 >30) {
$month1 = $month1+1;
//$remMonth = $month1-12;
$day1 = $day1-30;
}
//$day1 = date('d', $ts1);
echo $year1."-".$month1."-".$day1;

val year : Int = spinYear.getSelectedItem() as Int
selDate.text = "$year / $month / $date"
val curTime = LocalDateTime.now()
val curYear : Int = curTime.year
val difYear : Int = curYear - year
ageInMins.text = difYear.toString()
The language is Kotlin, and this is a part of my code.
The value year comes from a spinner named spinYear, and I got the selected value as an integer. Ultimately I want to substitute the text ageInMins with the value difYear.
I'm trying to define my difYear by subtracting the two variables: curYear and year, but the app crashes every time.
It seems like both of the variables I'm subtracting are of type Int, so I have no idea what to do with this problem.
If someone could give me an advice it would be great :)
I searched around Google to find information about this, but there was no useful information. I also tried to put .toInt() to the values but it didn't work. I tried every single thing I can think of, but it did not work. So I am seeking help from you guys.

Currently I am trying to polish this query. The problem I am having is using a UNIX Command to convert the time queried from timemodified into Human time. It comes out in epoch time. I have been attempting to use commands such as FROM_UNIXTIME(timestamp,'%a - %D %M %y %H:%i:%s') as timestamp. For reference this is a adhoc query to a moodle server contained in MariaDB. My desired result from the query is that nothing would change as far as the results we are getting, except that the time would be in a month/day/year format instead of the current format.
I have converted the timestamp into a custom date format using the below command in my select query.
DATE_FORMAT(FROM_UNIXTIME(`timestamp`), "%b-%d-%y")
As included in your question where you mention FROM_UNIXTIME(timestamp,'%a - %D %M %y %H:%i:%s'), it is indeed possible to include a second argument in order to specify the specific time/date format you wish to output converted from the UNIX timestamp.
That's the bit that looks like: '%a - %D %M %y %H:%i:%s' - this particular format string will give you an output that looks something like this: Fri - 24th January 20 14:17:09, which as you stated isn't quite what you were looking for, but we can fix that!
For example, the statement below will return the human-readable date (according to the value returned in the timestamp) in the form of month/day/year as you specified as the goal in your question, and would look similar to this: Jan/01/20
FROM_UNIXTIME(timestamp), '%b/%d/%y')
If you instead wish to use a 4 digit year you can substitute the lowercase %y for a capital %Y.
Additionally if a numeric month is instead preferred you can use %m in place of %b.
For a more comprehensive reference on the available specifiers that can be used to build up the format string, this page has a handy table
So putting it all together in the specific context of your original SQL query, using FROM_UNIXTIME to gain the human readable date (along with a suitable format string to specify the format of the output) may look something like this perhaps:
SELECT
prefix_grade_items.itemname AS Course,
prefix_grade_items.grademax,
ROUND(prefix_grade_grades_history.finalgrade, 0) AS finalgrade,
prefix_user.firstname,
prefix_user.lastname,
prefix_user.username,
FROM_UNIXTIME(prefix_grade_grades_history.timemodified, '%b/%d/%Y') AS grademodified
FROM
prefix_grade_grades_history
INNER JOIN prefix_user ON prefix_grade_grades_history.userid = prefix_user.id
INNER JOIN prefix_grade_items ON prefix_grade_grades_history.itemid = prefix_grade_items.id
WHERE (prefix_grade_items.itemname IS NOT NULL)
AND (prefix_grade_items.itemtype = 'mod' OR prefix_grade_items.itemtype = 'manual')
AND (prefix_grade_items.itemmodule = 'quiz' OR prefix_grade_items.itemmodule IS NULL)
AND (prefix_grade_grades_history.timemodified IS NOT NULL)
AND (prefix_grade_grades_history.finalgrade > 0)
AND (prefix_user.deleted = 0)
ORDER BY course
NOTE: I ended up specifying an alias for the timemodified column, calling it instead grademodified. This was done as without an alias the column name ends up getting a little busy :)
Hope that is helpful to you! :)
I am using Kayako Querying Language and trying to get the query to return all closed/resolved, closed/unresolved, and review tickets from a specified month. When I run the query, every ticket ever comes up, and it seems to ignore the date function I am using. What am I doing wrong?
SELECT COUNT(*) AS Total
FROM ‘Tickets'
WHERE ‘Tickets.Creation Date’ = month(June 2016) AND ‘Tickets.Status’ = ‘Closed’ OR ‘Tickets.Status’ = ‘Resolved’ OR ‘Tickets.Status’ = ‘Unresolved'
GROUP BY ‘Tickets.Status'
Thanks.
Replace the date comparison in your WHERE clause for this:
WHERE 'Tickets.Creation Date':Month = 6 and 'Tickets.Creation Date':Year = 2016
Be also careful with the quotes, you sometimes use ‘ and others '
I need to convert a date in 'MM/DD/YYYY' format to a number that say which day in the year it is. I.E '01/01/YYYY'=1 and '12/31/YYYY'=365. Is there any built in function to do this in ABAP? I've tried googling but I couldn't find any functions which did this
Here you go in one line of code:
DATA(g_day) = p_date - CONV d( p_date(4) && '0101' ) + 1.
It is absolutely unnecessary to rely on any function module that may or may not be present in your system. Just use basic built-in language elements:
DATA: l_my_date TYPE d, " note that the data type D is YYYYMMDD
l_jan_01 TYPE d, " This will be jan 1 of the needed year
l_day TYPE i.
l_my_date = ...whatever...
l_jan_01 = l_my_date.
l_jan_01+4 = '0101'. " or any other means to get the first day of the year.
l_day = l_my_date - l_jan_01 + 1.
You can use this function module: HR_AUPBS_MONTH_DAY.
You have to pass an initial date and an end date, and it will return the number of days in between (this is what you want):
CALL FUNCTION 'HR_AUPBS_MONTH_DAY'
EXPORTING BEG_DA = P_BEGDA " Here you should put the first day of the year
END_DA = P_ENDDA " Here you put the date
IMPORTING NO_CAL_DAY = P_CAL_DAY. " This is what you want
I'm trying to select records from a table based on a date using Linq to SQL. Unfortunately the date is split across two tables - the Hours table has the day and the related JobTime table has the month and year in two columns.
I have the following query:
Dim qry = From h As Hour In ctx.Hours Where Convert.ToDateTime(h.day & "/" & h.JobTime.month & "/" & h.JobTime.year & " 00:00:00") > Convert.ToDateTime("01/01/2012 00:00:00")
This gives me the error "Arithmetic overflow error converting expression to data type datetime."
Looking at the SQL query in SQL server profiler, I see:
exec sp_executesql N'SELECT [t0].[JobTimeID], [t0].[day], [t0].[hours]
FROM [dbo].[tbl_pm_hours] AS [t0]
INNER JOIN [dbo].[tbl_pm_jobtimes] AS [t1] ON [t1].[JobTimeID] = [t0].[JobTimeID]
WHERE (CONVERT(DateTime,(((((CONVERT(NVarChar,[t0].[day])) + #p0) + (CONVERT(NVarChar,COALESCE([t1].[month],NULL)))) + #p1) + (CONVERT(NVarChar,COALESCE([t1].[year],NULL)))) + #p2)) > #p3',N'#p0 nvarchar(4000),#p1 nvarchar(4000),#p2 nvarchar(4000),#p3 datetime',#p0=N'/',#p1=N'/',#p2=N' 00:00:00',#p3='2012-01-31 00:00:00'
I can see that it's not passing in the date to search for correctly but I'm not sure how to correct it.
Can anyone please help?
Thanks,
Emma
The direct cause of the error may have to do with this issue.
As said there, the conversions you use are a very inefficient way to build a query. On top of that, it is inefficient because the expressions are not sargable. I.e. you are using a computed value from database columns in a comparison which disables the query analyzer to use indexes to jump to individual column values. So, you could try to fix the error by doctoring the direct cause, but I think it's better to rewrite the query in a way that only the single column values are used in comparions.
I've worked this out in C#:
var cfg = new DateTime(12,6,12);
int year = 12, month = 6, day = 13; // Try some more values here.
// Date from components > datetime value?
bool gt = (
year > cfg.Year || (
(year == cfg.Year && month > cfg.Month) || (
year == cfg.Year && month == cfg.Month && day > cfg.Day)
)
);
You see that it's not as straightforward as it may look at first, but it works. There are much more comparisons to work out, but I'm sure that the ability to use indexes will easily outweigh this.
A more straightforward, but not sargable, way is to use sortable dates, like 20120101 and compare those (as integers).
