I ran the following code as part of a statement to capture
something occuring between the first of the current month and the end of the current month however when ever i refrence Stardate or Enddate i get the following error. Any ideas how to make the columns remain in effect throuhout the entire query?

Msg 207, Level 16, State 3, Line 10
Invalid column name ‘Startdate’.
Msg 207, Level 16, State 3, Line 10
Invalid column name ‘Enddate’.

declare @mydate datetime
select @mydate = getdate()

SELECT CONVERT(varchar(10),DATEADD(dd,-(DAY(@mydate)-1),@mydate),120) as ‘StartDate’

SELECT CONVERT(varchar(10),DATEADD(dd,-(DAY(DATEADD(mm,1,@mydate))-1),DATEADD(mm,-1,@mydate)),120) as ‘EndDate’

Haamidou,

Try this,

Select Datename ( dw, Dateadd ( dd , -1 , datename (yy, dateadd (year, +1, getdate()))))

Output : Thursday

Replace Getdate() with your date column name.

Please test this before using it in your code.

@Tania.

If you have SQL Server 2005 or higher , you can try this,

create table #temp(id int identity, ename varchar(10))
go

insert into #temp values (‘Testing’)
go 12 — This should not be replaced.

select datename (mm , dateadd (mm, id – (datepart(mm,getdate())), getdate())) Month_Names
from #temp
go

drop table #temp
go

I am sure, there is a better way of doing this, at-least this should give you a start.

@Vanessa

How about: SysDate >= DATEADD(m, 36, VISIT_date)

Though, 36 months is 3 years, so: SysDate >= DATEADD(yy, 3, VISIT_date)

By: Vanessa

Vanessa — Tue, 31 Mar 2009 14:38:28 +0000

Hello,

I tried to create the SQL statement with the condition:

“Today’s date > Month 36 after first VISIT_date” ?

I would think about 36 months * 30 days as:

(SysDate – VISIT_date) > (36*30)

But not every month has 30 days. Can any one help pls?

Thanks,

-Vanessa

@Verdel

Make the date March 1st, then subtract a day: select dateadd(yyyy, -1, dateadd(m, +1, dateadd(dd, – (datepart(dd, @period) – 1), @period)))

How do you get last day of month prior year for February where prior year was leap year?

Using the example above:

declare @period smalldatetime
set @period = ‘2/28/2009′

select cast(floor(cast(dateadd(yy,-1,dateadd(ms,-3,dateadd(mm,datediff(m,0,@period)+1,0)))as float)) as datetime)

Result: 2/28/2008

Need result to be 2/29/2008

Hi,

Here you can use computed column to get Age At contribution Date.

Example:

CREATE TABLE t1(
contribution_date DATETIME,
Dob DATETIME
)

INSERT INTO t1 (contribution_date, DOB) VALUES(NULL, ‘1977-07-01′
)

ALTER TABLE t1
ADD AgeAtContribution AS DATEDIFF(yy, DOB, contribution_date)

SELECT * from t1

You can also find my blog to add computed column at:

Thanks,

Hi,

For each month we have many weeks, some month will have 4 weeks but some will have 6 weeks ( for example for jan 09 , 01 -03 jan will be considered as Week1). How to find out the week number as per the above logic.

If i give a date the query should return it belongs wich week of the month.

i tried with datepart and week , but it returns week number for the year not for the month

Thanks
