SQL Work Week in format yyyyww - sql-server-2008

Does anyone know how i can filter a table by next weeks work week in the format 201337 which is yyyyww format.
The table would look like this
ww col1
201336 xx
201337 yy
201338 zz
i want to select 201336 xx. I normally use CURRENT_TIMESTAMP for timeDate:now but not sure how to get that to yyyyww

Try this:
DECLARE #nextWeek datetime
SET #nextWeek = DATEADD(day,7,GETDATE())
SELECT * FROM YourTable
WHERE ww =
CAST(DATEPART(year , #nextWeek) as char(4)) +
CAST(DATEPART(week , #nextWeek) as char(2))
See it working here.

SQL server triming

I am trying to format the licenseenum column in my table by removing everything starting the before space and also I would like to remove any character in licenseenum column starting after '-' including '-'
For example:
current data in Licenseenum GA 350-0
What I'm trying to get 350
Here is my code
select Licenseenum, SUBSTRING (Licenseenum, 4, LEN(Licenseenum)-1)
from licensee
this results
350-0
How would I remove -0 from the results?
Thanks for the help
Try it like this
DECLARE #YourString VARCHAR(100)='GA 350-0';
SELECT SUBSTRING(#YourString,CHARINDEX(' ',#YourString,1),CHARINDEX('-',#YourString,1)-CHARINDEX(' ',#YourString,1));
UPDATE 1
This is quite the same, but better to read
DECLARE #YourString VARCHAR(100)='GA 350-0';
WITH Positions AS
(
SELECT CHARINDEX(' ',#YourString,1) AS posBlank
,CHARINDEX('-',#YourString,1) AS posMinus
)
SELECT SUBSTRING(#YourString,posBlank,posMinus-posBlank)
FROM Positions;
UPDATE 2 Avoid the leading blank...
My logic needs small correction in order to cut the blank before the number:
SELECT SUBSTRING(#YourString,posBlank+1,posMinus-posBlank-1)
Would be the same with the first example...
Please try the below code. Its working fine in SQL Server 2012.
DECLARE #Licenseenum varchar(max)
SET #Licenseenum ='GA 350-0'
DECLARE #TempLicense VARCHAR(100)
DECLARE #License VARCHAR(100)
IF (len(#Licenseenum ) - len(replace(#Licenseenum ,' ',''))>=1)
SET #TempLicense = (SELECT REVERSE(LEFT(REVERSE(#Licenseenum ),CHARINDEX(' ', REVERSE(#Licenseenum ), 1) - 1)))
ELSE
SET #TempLicense = #Licenseenum
SELECT #License = (SELECT LEFT(#TempLicense,LEN(#TempLicense) - charindex('-',reverse(#TempLicense),1)))
SELECT #License AS Licenseenum

Age Calculation duplicate column using sql server 2008 R2

I have login table with DOB Column. I need duplicate column for age. But i can't do this. I can convert DOB column convert to Age for alone
`SELECT FLOOR(DATEDIFF(DAY,'10/10/1990' , getdate()) / 365.25)` works fine.
But I need to convert whole column.
If I'm Using
SELECT FLOOR(DATEDIFF(DAY,Select DOB From login_tbl , getdate()) / 365.25) like this,
It's throwing error. How can I get it?
Thankyou
Your approach will get wrong result in such cases below:
declare #now date
set #now = '11/10/2014'
select
FLOOR(DATEDIFF(DAY,'11/10/2013' , #now) / 365.25) -- should be 1 but will get 0
, FLOOR(DATEDIFF(DAY,'11/10/2012' , #now) / 365.25) -- should be 2 but will get 1
, DATEDIFF(DAY,'11/10/2013' , #now)
, DATEDIFF(DAY,'11/10/2012' , #now)
My suggestion is :
declare #now date
set #now = '11/10/2014'
select (convert(int,convert(varchar(8), #now ,112))
- convert(int,convert(varchar(8),convert(date,'11/10/2013'),112) ) )/10000
You could see my explain in this answer.
So for your login_tbl you could:
select
DOB, (convert(int,convert(varchar(8), DOB ,112))
- convert(int,convert(varchar(8),convert(date,'11/10/2013'),112) ) )/10000 as AGE
from
login_tbl
select trunc((trunc(sysdate) - to_date('16-mar-2010', 'dd-mon-yyyy'))/ (365.23076923074))
from dual

How to replace a date with a standard date in SQL

Ok,
This is a little tricky, I am trying to replace the dates in a SQL Query results with a standard date, based on the month.
For example:
Any dates that are in July get 20140701
August gets 20140801
I could use a case statement:
Case
When Datepart(mm, TxnDate) = 1 and Datepart(yy, TxnDate) = 2014 then TxnDate = 20140101
etc...
but that could get very long as the database goes back 5 years and the result sets cover different periods then.
Any quick suggestions would be greatly appreciated.
Thanks,
declare #mydate datetime
select #mydate = GETDATE()
select cast(datepart(yy,#mydate) as varchar(4)) + RIGHT('0' + RTRIM(MONTH(#mydate)), 2) + '01'
select #mydate = GETDATE() - 10
select cast(datepart(yy,#mydate) as varchar(4)) + RIGHT('0' + RTRIM(MONTH(#mydate)), 2) + '01'
should print 20140701 and 20140601
If you simply want to set every TxnDate to the first of its month, you can do this:
TxnDate = DATEADD(month, DATEDIFF(month, 0, TxnDate), 0)
If your requirement is more complicated than that, you will need to explain.
Try Something like this
SELECT REPLACE (CONVERT(VARCHAR(8), TxnDate, 112),SUBSTRING(CONVERT(VARCHAR(8), TxnDate, 112),7,8),'01') AS [YYYYMMDD]
hope this is what you are looking for

Hundred year date conversion in ssis derived column

I'm trying to convert a Hundred Year Date (HYD) format to a regular date format through SSIS derived column transform. For example: Convert 41429
to 06/04/2013. I can do it with formatinng code within a script (and maybe I simply have to go this route) but feel there has to be a way to do so within a derived column that I'm just not getting. Any help is appreciated.
This is what I came up with. Are you sure your conversion is correct? My answer is 1 day. off.
DECLARE #t1 as date = '01/01/1900';
DECLARE #t2 as DATE = '12/31/1900';
DECLARE #hyd as INT;
-- This example shows that we need to add 1
SELECT #hyd = DATEDIFF (d, #t1, #t2) + 1 -- 364 + 1
SELECT #hyd
set #t2 = '06/04/2013';
SELECT #hyd = DATEDIFF (d,#t1, '06/04/2013') + 1-- 41427
SELECT #hyd
SELECT DATEADD (d, #hyd, '01-JAN-1900')
SELECT DATEADD (d, 41429, '01-JAN-1900')
A hundred year date is a calculation based on the number of days since 1899-12-31. It's an "Excel Thing". It also has a bug in it that you must account for.
The equivalent TSQL logic would be
DECLARE
#HYD int = 41429;
SELECT
#HYD =
CASE
WHEN #HYD > 60
THEN #HYD -1
ELSE
#HYD
END;
SELECT
DATEADD(d, #HYD, '1899-12-31') AS HYD;
Armed with that formula, I can write the following Expression in a Derived Column Transformation (assuming you have a column named HYD)
(HYD > 60) ? DATEADD("d",HYD - 1,(DT_DATE)"1899-12-31") : DATEADD("d",HYD,(DT_DATE)"1899-12-31")
And the results
--or inline SQL...using this
SELECT
case when ([HYD] > 60) then
DATEADD(day,[HYD] - 1,'1899-12-31')
else
DATEADD(day,[HYD],'1899-12-31')
end 'HYD_conv'
FROM
TableName
--and in the where clause if you like...
WHERE
(case when ([HYD] > 60) then DATEADD(day,[HYD] - 1,'1899-12-31') else DATEADD(day,[HYD],'1899-12-31') end) = '2016-01-14'

problem with convert text to time in sql server 2008?

i have this Ttime as nvarchar(10): "09:52:48" and i have TmpTime as date
and i try to convert like this: "UPDATE MEN SET TmpTime = CONVERT(DATETIME, Ttime ,108 )"
and i get in TmpTime this: "1900-01-01"
why ?
thank's in advance
If you also have a date field, you should to concatenate them before to cast:
CREATE TABLE #Sample ( DateField varchar(10), TimeField varchar(10) );
GO
INSERT INTO #Sample VALUES ('2009-01-24', '09:52:48');
SELECT CONVERT(DATETIME, DateField + ' ' + TimeField) as Converted FROM #Sample
And you'll get:
Converted
-----------------------
2009-01-24 09:52:48.000
You have a column defined as "date" and then you are sending only a time value into it
The date portion defaults to zero which is 01 January 1900 in SQL (in the CONVERT). Then the time is ignored for a date column.
What do you expect to happen?
(The same would happen whether or not you use CONVERT or not because the column is "date")
