I'm using SQL SERVER 2005 and have a table which stores challans datewise. It has a field 'Quantity'
I want to have a sum of Quantity for the weeks of the month. But these weeks have to start from Tuesday To Monday (this is an international standard for Oil Accounting)
You can use set DATEFIRST to set the first day of the week, and then use datepart.
These SQL Statements should get you what you want. Assumption is that your table is called and the date column is
SET DATEFIRST 2;
select datepart(week, :my_date), sum(quantity)
from
group by datepart(week, :my_date)

I would like to select from a table where the date falls within a specific time each year f.e:
select * from Customer where date >= August 15th and date <= December 20th
Since this will be for a report that runs every year, I do not want to hardcore the date as I will have to change it every year. I would like to have it dynamic to pick the date from August 15th to December 20th of the current year.
I have the below query where I can retrieve the Month and Date:
SELECT DATENAME(month, date) AS Month,DATENAME(day, date) AS Day from Customer
However, I am struggling to have this selection date range.
TIA
In SQL SERVER 2017
maybe this can help you:
SELECT * FROM Customer WHERE date BETWEEN
CONVERT(DATETIME,CONCAT(YEAR(GETDATE()),'08','15')) AND
CONVERT(DATETIME,CONCAT(YEAR(GETDATE()),'12','20'))
This add the current year to a concatenated date you want, then convert it all into datetime type..
I have a series of email engagement dates, to create dashboard on QLIK. It has SQL Editor
I want to group a series of dates as Week 1, Week 2, and so on. My table has date column.
I am thinking along the lines for insert a column named "Week Number", based on the oldest date in the table, add 7 days range as week 1 and next 7 days range as Week 2 and so on.
In Qlik you can use the weekstart(Date) function or the week(Date) for just a week number. Either inthe script or as a calculated dimension in the chart.
Extra credit for year(Date)&'-'&week(Date) for 2019-23 etc
You can use datepart(wk, date_column) for grouping by week. You may want to add datepart(yy, date_column) to group by year and week.
You need to know the first day in your table was which day of the week, and then use the following script in SQL Server
declare #FirstDayOfTableWeekDay int = 2
SELECT CEILING( (CAST(ROW_NUMBER() OVER(ORDER BY [Date] ASC) AS float)+ CAST(#FirstDayOfTableWeekDay AS float)-1) / 7) AS WeekNumber
FROM YourTable
I'm trying to create a SQL statement (in H2 Dialect) that creates a DATE which is
the tuesday in the "week-of-year" that is two weeks from the current week.
For example, given CURRENT_DATE() returns 2014-04-23, the date that I want would be 2014-04-08, which is the Tuesday in the week that is two weeks before the week the Date "2014-04-23" is in.
How can I express this with H2's Date and Time functions?
In sql-server I would do it like this
DECLARE #date DATE = GETDATE();
SELECT DATEADD(DAY,3-DATEPART(WEEKDAY,#date),DATEADD(WEEK,-2,#date))
Where '3' represents day of the week (Tuesday) and '-2' represents subtracting two weeks.
So now in h2 it is very similar
SELECT DATEADD('DAY',3-DAY_OF_WEEK(CURRENT_DATE()),DATEADD('WEEK',-2,CURRENT_DATE()))
How will I calculate week number within a date range ? Here my week starts from Saturday to Friday. And I have a start date and end date. With this, how will i calculate using SQL Query ?
Use DATEPART to get the Week number,
and DATEFIRST to set the first day of the week. (See http://msdn.microsoft.com/en-us/library/ms181598.aspx)
Example to get all week numbers in range with Saturday as the first day of week.
SET DATEFIRST 6
SELECT DISTINCT
DATEPART(WEEK, createDate)
FROM
tblUser
WHERE
createDate > '2005-01-01' AND createDate < '2011-01-01'
ORDER BY
DATEPART(WEEK, createDate)
You can use this and your SQL work operates well:
SET LANGUAGE us_english -- with your language
GO
I want to calculate Last Week Number of Month in SQL. I am having Week Number and Year.
Eg. If I pass WeekNo=51 , Year=2008 , than function should return LastWeekofMonth= 52.
I want to calculate Week number using below standards.
According to ISO 8601:1988 that is used in Sweden the first week of the year is the first week that has at least four days within the new year.
So if your week starts on a Monday the first Thursday any year is within the first week. You can DateAdd or DateDiff from that.
Please Help me..........
Thanks in advance.
SELECT WEEK(LAST_DAY(STR_TO_DATE('2008-51-Mon', '%x-%v-%a')));
Should do the trick for getting the last week number of month with MySQL :
I first convert to a date, then I get the last day of the month (here: 2008-12-31), then I compute the week of the last day of the month (52).
It should be easy to turn it into a function.
Hope this helps.
This is fairly straightforward if you use a calendar table. The month you need is given by this query.
select iso_year, month_of_year
from calendar c
where iso_year = 2008 and iso_week = 51
group by iso_year, month_of_year
--
iso_year month_of_year
2008 12
So you can use that result in a join on the calendar table, like this.
select max(c.iso_week) as last_week_of_month
from calendar c
inner join
(select iso_year, month_of_year
from calendar c
where iso_year = 2008 and iso_week = 51
group by iso_year, month_of_year) m
on m.iso_year = c.iso_year and m.month_of_year = c.month_of_year;
--
last_week_of_month
52
Here's one example of a calendar table, but it's pretty thin on CHECK constraints.
If you're using SQL Server, you can perform a calculation by using a master table, without creating a calendar table. This fellow gives you a very good explanation, which I recommend that you read. His SQL for calculating the first and last Sundays of each month can be adapted for your use:
declare #year int
set #year =2011
select min(dates) as first_sunday,max(dates) as last_sunday from
(
select dateadd(day,number-1,DATEADD(year,#year-1900,0))
as dates from master..spt_values
where type='p' and number between 1 and
DATEDIFF(day,DATEADD(year,#year-1900,0),DATEADD(year,#year-1900+1,0))
) as t
where DATENAME(weekday,dates)='sunday'
group by DATEADD(month,datediff(month,0,dates),0)
Edit: Once you have the date of the Thursday, you can get the week number from that date like this:
DECLARE #Dt datetime
SELECT #Dt='02-21-2008'
SELECT DATEPART( wk, #Dt)
