DATEDIFF Possibilities
Aug 10, 2004
Hi,
I have two fields in one of my database table. They are date fields, one for the start and the other for the end of the "problem solving". What I want to do is to show the concrete elapsed time between the two.
My first problem is that I'm not able to show hour AND minutes. I wrote this for instance:
SELECT DATEDIFF(hour, fld_date_debut, fld_date_fin) As elapsed_time
I tried HH:mm instead of hour, but it is not working.
My second problem is that I can have more than one start and end hour for the same "problem solving". In the database it's like:
start hour: 10:00 End hour: 11:00 Number of the problem: 1
start hour: 13:00 End hour: 16:00 Number of the problem: 1
So I would like to add these to my elapsed time. I want (11:00 - 10:00) + (16:00 - 13:00)...but how can i do this in my SQL query ?
Thanks.

Dear SQLGuru,
I came to know one of the better option in Oracle SQL for TOP-N Analysis-To find the top 5 usage accounts, top 10 users, etc. Is there any such way in SQL server ?
Is there any ways of using JOINS ( using keyword INNER & OUTER ) ? Some of the scripts that is generated automatically in Microsoft access with Join condition is not even working in MSSQL server 6.5. Is it true ? Or is there any other way that I can use these scripts in SQL 6.5.
If possible, pls. help me with some sample scripts ?
Thanks a lot in advance.

How can I do a lookup which doens't directly link two columns but uses another statement?
I tried in advanced with:
Code Snippetselect * from
(select * from [dbo].[Employees]) as refTable
where [refTable].[EM_ID] = ? and [refTable].[EM_From] <= ? and
([refTable].[EM_Until] > ? or [refTable].[EM_Until] IS NULL)
and adding 2 parameters.
Error 1 Validation error. Fill Planning: Lookup [2376]: An input column with the lineage ID 1760, referenced in the ParameterMap custom property with the parameter on position number 1, cannot be found in the input columns collection. Package.dtsx 0 0
So I guess that's not the way to go. Any other way to tackle this?

I have a bunch of contacts that I've scored how well their names match to other contacts in the same business. I can programmatically figure out how to parse the results, but would like to know how to do this via SQL. My problem is for Business_fk 968976 I have 7 contacts. In the end I should have 4 contacts based on name match. For the business key listed Gerardo Lopez is in the ContactScore table twice for Contact keys 7355719 and 57028145. I then have two rows like so:
PossibleBusinessContactMatch_pk BusinessContact_fk Business_fk BusinessContactMatch_fk MatchTypeCode MatchScore MatchRank FirstName LastName Phone Email
------------------------------- ------------------ ----------- ----------------------- ------------- ----------- ----------- -------------------------------------------------- -------------------------------------------------- ---------- --------------------------------------------------------------------------------------------------------------------------------
1772960 57028145 968976 7355719 C 46 1 GERARDO I LOPEZ 8162214000
838834 7355719 968976 57028145 C 50 1 GERARDO
Each reference each other, and 2 is a good case, a more difficult case would have key 1 listed 10 times showing a ContactMatch_fk of 2 - 11, and then Contact_fk 2 listed 10 times with a ContactMatch_fk of 1, 3-11.I know 57028145 maps to 7355719 from the first row in the ContactScore table, so when Contact_fk of 7355719 comes up I should be able to skip it and not process that match. Hopefully that makes sense. Anyway here is the test data:
IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[ContactScore]') AND type in (N'U'))
DROP TABLE [dbo].[ContactScore];
GO
CREATE TABLE [dbo].[ContactScore]
(
[ContactScore_pk]INT NOT NULL,
[Contact_fk]INT NOT NULL,
[code]..

Hello,
My string is:
SELECT weight FROM progress WHERE dateInput = (SELECT MAX(dateInput) FROM progress) AND memberID = 1
The problem is that the MAX dateInput doesn't belongs to memberID 1. It belongs to memberID 2. What I want is that I wanna choose the MAX Date of memberID 1. I thought of maybe using datadiff function. But I don't know how to make the datediff statement. Maybe I can write the datediff statement whereby the least datediff between the dateInput and getdate() will be the row I want. I really appreciate the person that helps me this problem... Thanks 1st of all!

I am trying to select records from whatever the current date would be and 12 months before whatever the current date is. How would I go about doing this. The table that I am trying to do this with has a year column and a month column.
I was playing with the date diff function, but I can only get dates from the specified date range. I need it to be where if I run it tomorrow, it will get that day and everything within the last 12 months.

I need to get a listing of all persons who are atleast 18 years of age. A date of birth field in the database is in this format:
4/25/2008 12:00:00 AM
My solution would be where the difference between the current date and the dob is >= 18.
I tried...
select * from table where datediff(yy,dob,getdate)) >= 18.
But this only seems to subtract the years and ignore the days/months, which I need. Could anyone provide the syntax I need?
Help is appreciated. Thanks.

Hi there i am using the datediff funtion but it does not seem to be inclusive of the two dates eg
SELECT DATEDIFF(day, s_Date, e_date) AS NumberOfDays,*
FROM weekendtest
i know i could do
SELECT DATEDIFF(day, s_Date, e_date)+1 AS NumberOfDays,*
FROM weekendtest
but i was just wondering if there some other function i should use that would be more appropriate

I'm trying to use the same select statement I used in classic SQL, but it isn't working. I get a "The server tag is not well formed." error.
I'm trying to return all the records where the date in a particular field are over 60 days old. My select statement is:
"SELECT [ReNewAd], [Male or Female], [File2], [PHOTO], [First Name], [Last Name], [City], [State], [NewAd] FROM Members Where ('NewAd' IS NOT NULL AND (DateDiff('d', [NewAd], '" & Now() & "') <= 60)) order by [NewAd] Desc"
I've been looking through the datediff posts, but I'm not making any sense of what I'm reading. Can anyone see what I'm doing wrong?
Thanks, Diane

hello,
i have a Pictures table: PictureID, Name, Description, DateAdded (GETDATE() when insert), IsActive...
i need to make some stored procedures to show me the pictures added in last 24hours, in last 3 days, last 2 weeks and so on
the pictures added in database are active (available to be seen by users) only 1yaer after the date added
I tryied to make a stored procedure (in fact i maked a lots of them, for 1day 3 days 1 week 1 month), but i have a problem with that DateDiff and DateAdd
Here is what i tryied CREATE PROCEDURE LastAdded_2monthsAgo
AS
SELECT Pictures.ProductID, Pictures.Name, Pictures.Description, Pictures.DateAdded
FROM Pictures
WHERE (DATEDIFF(month, Pictures.DateAdded, GETDATE()) >= 0) AND (DATEDIFF(month, Pictures.DateAdded, GETDATE()) <= 2)
ORDER BY DateAdded DescI have a feeling that is wrong, please make your own version and show me what i should write...I don't know what should be first the today date or the DateAdded...i need to select the last added products from a specific interval of time...Should i do something with that "1 year available" like WHERE (DATEDIFF(month, GETDATE(), DATEADD(year, 1, Products.DateAdded)) >= 0) AND (DATEDIFF(month, GETDATE(), DATEADD(year, 1, Products.DateAdded)) <= 2) I am sure is a stupid thig up there...if you can, make your own version how you would do it and show me..please help me

Hi,I'm using the datediff function to display the ages of the users in my database. However the age rounds up once they are 35.5 etc...I could create another function which works similar to the DateDiff function, but use math.floor to always round down, but I need to use this function in a SQL statement WHERE clause. Is there any way around this?Thanks,Curt.

This is a sql question, so I'm hoping someone can give me some direction.
I need to query a table and return all rows where the individual is >= 18 years of age. It should involve simply subtracting the date of birth from the current date. I thought the answer would be so simple:
select * from table where datediff(yy,dob,getdate()) >= 18
Unfortunately, the results are inconsistent. The DATEDIFF function, it appears, will not show correct results down to the month/day level. I tried posting this on a sql server forum, but the recommendations I received involved coding some gigantic function. It seems that there ought to be a simple 'WHERE' clause which could solve this.
If someone knows of a silver bullet, I would surely appreciate your advice.
Thank you.

I'm trying to include a DATEDIFF compare in my Where clause, but it seems to ignore the comparison I'm trying to invoke, and just returns all rows. When I display the result of the DATEDIFF command, it looks good, but I can't seem to have it incorporated in my Where clause.
The following is my code -
select [Pkg ID], [Elm (s)], [Type Name (s)], [End Exec Date], [End Exec Time]
from pkgactions
WHERE (8 > DateDiff(year, [End Exec Date], GetDate() ))
order by [pkg id]

Hello everyone.
Im currently using the DateDiff function to filter my DateTime columns but am finding it somewhat troublesome. Currently I am having to write the same select statement 3 times if I want to filter by month, year or all (ignoring dates).
To find @PurchaseTotal for the year, I have to write the following:
SELECT
@PurchaseTotal = Sum(PurchaseTotal)
FROM
_Expenses
WHERE
DateDiff(yyyy, DateOf, @IntervalDate) = @Interval
To find @PurchaseTotal for a month, I have to write the following:
SELECT
@PurchaseTotal = Sum(PurchaseTotal)
FROM
_Expenses
WHERE
DateDiff(mm, DateOf, @IntervalDate) = @Interval
To find @PurchaseTotal for all the records, I have to write the following:
SELECT
@PurchaseTotal = Sum(PurchaseTotal)
FROM
_Expenses
I've tried the following code but I get an error.
DateDiff(@DateParameter, DateOf, @IntervalDate) = @Interval
Error says something like "incorrect parameter 1 for DateDiff."
It seems you have to write a different select statement for month, day and year. Also If you want a total from all the records you have to write yet another select statement.
Does anyone know of a DateTime function that allows parameters to specify for month, day and Year? Also does anyone know of a DateTime function that works like the COALESCE function to where you can send it a NULL value and give you all the records?
Thank you ahead for any direction you can give.
Alec

hi gurus,
can anyone tell me how to write a query which you could use like a hotel wakeup call system with an email sent instead of a phone call. the fields in the table would only be the target email address and date/time of the event. i suspect the query would run on a 10 minute meta-refresh asp page containing the email broadcast app along with the query.
thanks

Hi
I'm trying to break down some code to work out how it's working. I've encountered DateDiff and DateAdd and I think this adds a new date of midnight today after reading up on the syntax (still dont fully understand how it works to be honest)
SELECT DATEADD(dd, DATEDIFF(dd, 0, GETDATE()), 0)
However, this is slightly different because where there is a 0 above there is a 13 in this one so I'm wondering what the 13 is actually doing.
SELECT DATEADD(dd, DATEDIFF(dd, 13, GETDATE()), 0)
In this one there's a 21
SELECT DATEADD(dd, DATEDIFF(dd, 21, GETDATE()), 0)
Can someone guide me please?
Thanks
