Convert Date Range Into Week Days

Nov 3, 2006

Hi,

I don't know if this can be done, but hopefully one of the experts in this forum cna help me out.

I have a TimeOff table which contains 5 fields: timeoffID, employeename, startdate, enddate, and timofftype. I need to create a report which shows how many people take sick day (one of the timeofftypes) on each week day (i.e. Monday, Tuesday, Wednesday, and etc.) The problem is that I don't know how to convert the date range (from startdate to enddate) into indvidual week day for each timeoff record.

For example, on the table,

TimeoffID employeename startdate enddate timeofftype
1 Andy 11/02/2006 11/03/2006 Sick Day
2 Bill 11/03/2006 11/03/2006 Sick Day

The report needs to show:

Monday Tuesday Wednesday Thursday Friday Saturday Sunday
0 0 0 1 2 0 0


Thank you in advance!

Transact SQL :: Convert Server Date MM/DD/CCYY To Oracle Date Formatted As NUMBER (8,0)

Apr 30, 2015

So I have to build dynamic T-SQL because of a date parameter that will be provided. The Date Parameter will be provided in SSRS in normal MM/DD/CCYY format. So how do I then convert that date to my Oracle format

NUMERIC(8,0) CCYYMMDD?

I tried this...

SET@SQLQuery=@SQLQuery+'ANDMEMBER_SPAN.YMDEFF<='''''+CAST(@AsOfDateASVARCHAR)+''''''+@NewLineChar;
SET@SQLQuery=@SQLQuery+'ANDMEMBER_SPAN.YMDEFF>='''''+CAST(@AsOfDateASVARCHAR)+''''''+@NewLineChar;

but that put it in the format of...

AND
MEMBER_SPAN.YMDEFF<=''2015-04-01''
AND
MEMBER_SPAN.YMDEFF>=''2015-04-01''

Which is close...I think I just need to lose the "-"

Convert Day Of Week Integer To Weekday Name?

Sep 10, 2007

In a table, I store an integer to represent a day of the week (1 = sunday ) and then in procedures, compare that to datepart(dw, getdate()) to do alternative tasks on certain days.

If I have the number 1, is there a built in function to convert that to sunday or should one just write a function to do just that?

SIMPLE Command To Convert String To Number? Not CAST Or CONVERT.

Aug 15, 2006

Dear Experts,Ok, I hate to ask such a seemingly dumb question, but I'vealready spent far too much time on this. More that Iwould care to admit.In Sql server, how do I simply change a character into a number??????In Oracle, it is:select to_number(20.55)from dualTO_NUMBER(20.55)----------------20.55And we are on with our lives.In sql server, using the Northwinds database:SELECTr.regionid,STR(r.regionid,7,2) as a_string,CONVERT(numeric, STR(r.regionid,7,2)) as a_number,cast ( STR(r.regionid) as int ) as cast_to_numberFROM REGION R1 1.00112 2.00223 3.00334 4.0044SELECTr.regionid,STR(r.regionid,7,2) as a_string,CONVERT(numeric, STR(r.regionid,7,2) ) as a_number,cast (STR(r.regionid,7,2) as numeric ) as cast_to_numberFROM REGION R1 1.00112 2.00223 3.00334 4.0044Str converts from number to string in one motion.Isn't there a simple function in Sql Server to convertfrom string to number?What is the secret?Thanks

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.

Date Of First Day In Week

Apr 27, 2005

I need to write a user defined function that will return the date of the first day of a week when provided with the week number. I had an idea of using a while loop with that will keep adding 1 day from January 1st until the week number (found via the DATEPART function) is equal to the supplied week number. Not sure if this is the best way though - any ideas?

Donald.

Date Of First Day Of Week

May 26, 2008

I'm wanting to see if there is a simpler way to accomplish the retrival of the first day of the week Date. What I currently have is:

CASE
WHEN DATEPART(DW, GETDATE()) = 1 THEN DATEADD([D], - 7, GETDATE())
WHEN DATEPART(DW, GETDATE()) = 2 THEN DATEADD([D], - 8, GETDATE())
WHEN DATEPART(DW, GETDATE()) = 3 THEN DATEADD([D], - 9, GETDATE())
WHEN DATEPART(DW, GETDATE()) = 4 THEN DATEADD([D], - 10, GETDATE())
WHEN DATEPART(DW, GETDATE()) = 5 THEN DATEADD([D], - 11, GETDATE())
WHEN DATEPART(DW, GETDATE()) = 6 THEN DATEADD([D], - 12, GETDATE())
WHEN DATEPART(DW, GETDATE()) = 7 THEN DATEADD([D], - 13, GETDATE()) END AS StartWeek1


I'm trying to figure if there might be an easier way to code this. Thanks.
