I have the following SQL statement that works out how many days are between todays date and the first of April 2007.
SELECTDATEDIFF(dd,'2007-04-01 00:00:00.000',GetDate()) AS 'Days Left'
This works fine, however: After the 1st April 2007 I want to start counting down the days till 1st April 2008 - and so on and so forth.
How can I do this? Hopefully you understand my question - if not, ask me any questions needed!
Cheers - GeorgeV
I have one query that looks like this.
DECLARE @propname
SET @propname = NULL -- can be Null or have wild card values
SELECT col1, col2, col3, propertyname FROM testtable where col1 = 1 and col2 = 2 and col3 = 3 and (@propname IS NULL OR propertyname LIKE @propname)
col1, col2, col3 are part of a clustered index
propertyname is a nonclustered index
This is the predicament. If the "@propname is NULL" is first in the OR statement then the query will use the clustered index for finding the record. If I put "@propname is NULL" last then it uses the propertyname index no matter what. So I either get full index scans if NULL is ever used on property names or I get consistent two second long searches on the clustered index. Any way to have the best of both worlds? Or do I have to divide up my query into more stored procedures?
THANKS
Hi guys,Got a problem now :( please help...now we got a project handling records saved in a table in a sql2000(will upgraded to 2005 soon) server. every month around a millionrecords will be inserted.now user raised a request, that is, once criterios are matched, theproject should do some backend handle, for example, ifSELECT colID, fieldC, fieldD FROM dataTable WHERE fieldA ='fieldA_valueB'returns some recordset, for each @fieldC, @fieldD we shall do someback-end trick, maybeUPDATE dataTable SET fieldE = 'fieldE_valueF' WHERE fieldC = @fieldCAND fieldD = @fieldDlet's say such a rule is named as rule01. Hope I'm expressing theproblem clearly?my questoin is, shall we do this in Database side, using triggers, orby informing our .net project to do it?1. since the records are coming around 1 millison per month, how can wehandling the performance issue?2. now the rules are still somewhat simple, seems at least we could doit by EXEC or SP_EXECUTESQL. but rules may turn quite complex, forexample, audit log, or more complex issues, shall we do it in .netprogram? but how can a trigger in SQL database informing a .netprogram, or webservice, or windows service? by executeing an executableconsole program?3. user may raise more and more rules, how could we provied a flexiblesolution? i mean we're trying to build it less hard-coded. seems in sqldatabase EXEC or SP_EXECUTESQL are still somewhat flexible, while in..net to do something like eval() in javascript or EXEC in sql server isa little bit troublesome. but, put all these bussiness logic in storedprocedure sounds a little bit weired.guys, hope i have made myself clear. any suggestion? Thanks very mcuhyours,athos.
View 7 Replies View RelatedI would like to build a report with nice functionalities like filter, sorting, drill-down, something like a PowerPivot Table, but with some layout/design/format capabilities. I would also want to publish the report, refresh it let´s say once a week, notify users when a new version is available, etc.
If I use PowerPivot, then I am not able to customized the report or to mix data from different sources in one table.
If I convert the cells of the PowerPivot table to workbook formulas I lose the filter, sorting, etc functionalities.
I still have to try using Reporting Services, but I think that always something is missing.
If I wanted to get everyone DOB who is over 18 how would I do that? I am currently trying something like this, but no luck...

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
Hi
I've a problem!!!
i want to use datediff thats no problem. But the first parameter has to
be parameterised. What datatype do i declare it as. i declare it as varchar
it returns me an error : Invalid parameter 1 specified for datediff.
i'm doing this in a stored procedure.
Is there a way out or do i've to use the good old 'IF' or 'Case' ?

Could somebody please explain to me why I get the following results:
select datepart (ww, '10/02/08') --returns 6
select datepart (ww, '18/02/08') --returns 8
select datediff (ww, '10/02/08', '18/02/08') -- returns 1
I was expecting the third query to return 2.
Thanks.

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.
View 3 Replies View RelatedThis 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]
Thanks
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.
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.

I just discover the result for my query that had use the function dateDiff seems to be in-correct, no matter what's the date, the dateDiff always return a zero. Am I using it in-correctly?

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

Hi GUYS
I am trying to use the datediff function to return a Y if difference is greater than 0 and a N if difference is less than or equal to 0
select if datediff(dd,maturity_date,log_changed) > 0 'Y','N')
and i am getting a syntax error.Can someone show me where i am getting it wrong.
In god we trust,everything else we test.
Guys,
I am not an expert in access or SQL. I have a simple Fn. to be executed. I would like to use DATEDIFF fn. in access 2007 for calculating the number of days between current date and a given date within a table.Please help me.
Please tell me how to use DATEDIFF for doing this?
My code is
select *
from Student
where DATEDIFF(YY,[Date],getdate())>=17
AND YEAR = 1
group by StudentName LIKE 'IT%'
order by Name ASC, Age DESC;
And having a problem to view the DATEDIFF as age and also having error:
Msg 156, Level 15, State 1, Line 5
Incorrect syntax near the keyword 'LIKE'.
I'm looking to apply a secondary order to a select query based on the difference in hours between now and a stored date/time. Effectively I'd like to place records with a datediff of over 2 hours to the top of the sort;
ORDER BY DATEDIFF(hour,FullLatestCallTimeStamp,Getdate() > 2) DESC
My Problem is that I get a syntax error on the '>'
hi all,
can i have brief explaination of datediff and dateadd function, regarding their arguments and params, definitions.. like the books online definition.. anybody have the books online url?
