Transact SQL :: Get Week Number From DateTime Field?
Aug 21, 2015
Any easier way to do what I am trying, without having a table with all the dates and week numbers.
Scenario: Week number of a DateTime Field where the year does not start on January 01<sup>st</sup> but April 1<sup>st</sup> to 31 Mach.
Issue: A week always starts on a Monday so if the 1<sup>st</sup> is on Tuesday, the first week is Tuesday – Sunday, if the 1<sup>st</sup> April is on Friday, the 1<sup>st</sup> week is Friday – Sunday and 7 day periods from there.
CREATE
TABLE [dbo].[DailyCanx](
[ID] [int] IDENTITY(1,1)
NOT NULL,
[DateCancelled] [datetime] NULL
)
ON [PRIMARY]
[code]....
I could create a table with all the start date and end dates of all the week numbers but I think there must be a better way. using SQL Server 2008 R2.
SQL express 2012. I am trying to case in the where part and having a syntax errors - This is what i am trying to do:
select all the days in week number x including last year if necessary... so if the year start not at the beginning of the week then look in last year as well ( for the same week number of this year and last week nu of last year)
declare @yyyy int = 2014,-- THE YEAR @mm int = 1,-- THE MONTH @week1No int = 1,-- THE WEEK NUMBER IN THE YEAR @week2No int = 37-- THE last WEEK NUMBER IN last YEAR select count(tblDay.start)-- tblDay.start IS smallDatetime

I need a Select sentence that return me the first week of the month for a given week.
For example If I have week number 12 (Begins 2015/03/16 and Ends 2015/03/22) I need that returns 9, I mean Week number 9 wich is the first week of march (having in mind @@DATEFIRST).
I only need give a week number of the year and then returns the week number of the first week of that month.
I have a table of errors with a DateTime field for when the error occurred. I want to query the table for a given date range omitting the time portion. What is the most efficient way to perform this query?
aaaaa bbbbb date result ------- ------- -------- --------- a 100 7-7-15 a 100 7-7-15 a 100 8-7-15 b 200 7-7-15 b 200 8-7-15 b 200 8-7-15
I need this (divide bbbbb by row count as result, group by "aaaaa and date":
aaaaa bbbbb date result ------- ------- -------- --------- a 100 7-7-15 50 a 100 7-7-15 50 a 100 8-7-15 100 b 200 7-7-15 200 b 200 8-7-15 100 b 200 8-7-15 100
Can I do it?
My SQL Code is
(date=FEC, RESULT=COSTECUB, aaaaaa=TRACTA, bbbbb=TRAPR3) : SELECT VTRA00F.TRACTA, ACRDES, TRAPRL, TRAPR1, TRAPR2, TRAPR3, CASE WHEN TRAPR3 IS NULL THEN (CASE WHEN (ALLQDE+ALLQCN+ALLQCR+ALLQMR+ALLQNN+ALLQNR+ALLQV1+ALLQV2) <= TRAPRL THEN (TRAPR1*(ALLQDE+ALLQCN+ALLQCR+ALLQMR+ALLQNN+ALLQNR+ALLQV1+ALLQV2)) ELSE (TRAPR2*
I hope to update a DateTime column value with a Time input parameter. Poor attempt below but it looks like the @ApptTime param is coming in as 10:45:00.0000000 and I might have an existing @SendOnDate as: 2015-10-05 07:00:00.000...I hope to end up with 2015-10-05 10:45:00.000
ALTER PROCEDURE [dbo].[SendEditUPDATE] @QuePoolID int=null ,@ApptTime time(7) ,@SendOnDate datetime
I am working with Week Numbers and was wondering if there is a way to display Week 1 as 01.
The problem that I am having is that when I list the weeks from Week 1 to Week 12 is that the sorting is 1, 10, 11, 12, 2, 3 and I would like to get it to look like 01, 02, 03....09, 10.
Our reporting group would like to generate reports based on day of the week. Is there a function or other means of determining the day based on data in a datetime field? Thanks for any assistance in advance.
So I need to select and average a whole bunch of data by week. Currently, I group by:
GROUP BY TO_CHAR(m.ENDTIME, 'IW')
and select using
SELECT ... TO_CHAR(m.ENDTIME, 'IW') Week
to summarize by week.
Since the first day of the year was a monday, it sets the weeks as monday-monday. I need to set the weeks to be Thursday 7pm to Thursday 7pm. How can this be achieved? Thanks.
I want to convert date to week consider saturday is first day of week and friday is end of week. for input is orderdate and output should be week. example orderdate 11.04.15 to 17.04.15 week should be 16. orderdate 18.04.15 week should change to 17.
Order DateWeek 11-Apr-201516 12-Apr-201516 13-Apr-201516 14-Apr-201516 15-Apr-201516 16-Apr-201516 17-Apr-201516
Hi all, having a little problem with saving dates to sql databaseI've got the CreatedOn field in the table set to datetime type, but every time i try and run it i get an error kicked up Error "The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.The statement has been terminated."I've tried researching it but not been able to find something similar. Heres the code: DateTime createOn = DateTime.Now;string sSQLStatement = "INSERT INTO Index (Name, Description, Creator,CreatedOn) values ('" + name + "','" + description + "','" + userName + "','" + createOn + "')"; Any help would be much appreciated
I need to generate the week ranges like this format :
Here from date and to date would be picked up from the table but just to make you understand i have hard coded it but this is the real date which is falling inside the table.
Note : Week should be generated from Monday to Sunday within desired date range
I have to insert YEAR WEEKNUMBER STARTDATE ENDDATE values to a datatable (sayweekrange), if I pass 2011 as year.
Week range starts at 2011-03-28 to 2011-04-03 (because in my database 2010 last week range ends with 2011-03-27) like this I have to generate for 52 weeks.
I want to write a stored procedure, that takes only year as parameter. with this year I have to generate week ranges and insert into my table as shown above.
I need to run a select on Mondays to pull data for 7 days prior to the Thursday of last week; i.e. Friday - Thursday inclusive. I'm sure this is simple, but I work with dates so infrequently that I need a refressher.
I have a query to check the records of job has received after 4pm Monday to Friday and it has completed before 9am next day and also weekend it should be Friday after 4pm and before Monday 10am for particular financial year period. I have my job table which has full date but it doesn't show the date exactly Monday to Friday it shows only as 12-12-2014 like that.
I am trying to drag data from Informix to Sql Server. When I kick off the package using an OLE DB Source and a SQL Server Destination, I get DT_DBDATE to DT_DBTIMESTAMP errors on two fields from Informix which are date data ....no timestamp part
I tried a couple of things:
Created a view of the Informix table where I cast the date fields as datetime year to fraction(5), which failed.
Altered the view to convert the date fields to char(10) with the hopes that SQL Server would implicitly cast them as datetime but it failed.
declare @NumberToCompareTo int set @NumberToCompareTo = 8 declare @table table ( number int ) insert into @table select 4
[Code] ....
The query selects 4 and 5 of course. Now what I'm looking for is to retrieve the number less or equal to @NumberToCompareTo, I mean the most immediate less number than the parameter. So in this case 5
