Why Is Getdate() Slower Than DATEADD()
Aug 22, 2007
I was tasked with optimizing a query that was taking about 2.5 minutes to run. It is now running in 2 seconds, so great, it's working....except I don't understand why. The ONLY change made is the where...
Here is the origional
Code Snippet
WHERE (j.datelaunched > GETDATE() - 7 OR (j.jobtype_id = 2 AND j.datecreated > GETDATE() - 30)
Here is the optomized
Code Snippet
WHERE (j.datelaunched >= DATEADD(DD, DATEDIFF(DD,0,GETDATE() - 7), 0) OR (j.jobtype_id = 2 AND j.datecreated >= DATEADD(DD, DATEDIFF(DD,0,GETDATE() - 30), 0)))

I am begginner at best so I hope someone that is better can help.I have a stored procedure that updates a view that I wrote using 2cursors.(Kind of a Inner Loop) I wrote it this way Because I couldn'tdo it using reqular transact SQL.The problem is that this procedure is taking longer and longer to run.Up to 5 hours now! It is anaylizing about 30,000 records. I thinkpartly because we add new records every month.The procedure works like this.The first Cursor stores a unique account and duedate combination fromthe view.It then finds all the accts in the view that have that account duedatecombo and loads them into Cursor 2 this groups them together for datamanipulation. The accounts have to be grouped this way because aaccount can have different due dates and multiple records within eachaccount due date combo and they need to be looked at this way aslittle singular groups.Here is my procedure I hope someone can shead some light on this. Myboss is giving me heck about it.

hi, friends, please look at this:
I have a SSIS package, and inside it I do something like below:
1. I have a SQL component, to give back a object to store the records.
2. I have a VB script component, I direct the object I got in 1 step into the script as a dataset.
My problem is:
I run the package in the SQL SERVER 2005 Store Procedue like this:
do
dtexec.exe package.dtsx
loop untill i>t
I control the it runs 30 times. But I found that the speed is slower and slower.
the first time, it takes about 600 s, but the last time, it takes the 1800 s.
Why?
The package don't drop the object it create during the loop in the Store Procedue ?
Thanks!

Hi
Hope someone can help.
I've got to produce a report that filters information dependent on the purchase date based on various parameters.
The parameters are:
@yearend (Datetime)
@months(int)
the script that I wrote in SQL is
select assetno from assets where purch_date < = dateadd(mm,-@months, @yearend)
but when I try to use this in the dataset it comes up with the following error:
"Application usess a value of the wrong type for the current operation"
Any help would be very much appreciated.

If I am running a scheduled job at the first of the month and I want to run an update sequence for the previous month, i was essentially using this sql:
@startdate = dateadd(mm, -1, getdate())
@enddate = dateadd(dd, -1, getdate())
So, will the @enddate represent the last day in the previous month or will that not work?

I am using Derived Column Transformation Task to format my data as I am converting my DTS to SSIS. One of the columns requires to use DATEADD where I add 1 month and substruct one day from the date that I get in the flat file.(note that I always hardcode the day to "01" regardless of what I get in my flat file)
The current script looks like this:
DTSDestination("PeriodEndDate") =
dateadd("d",-1,dateadd("m",1,cdate(mid(cstr(DTSSource("Col004")),1,4) & "-" & mid(cstr(DTSSource("Col004")),5,2) & "-" & "01")))
Does any one know how to convert it so it works in my derived column?
Thanks...

when I execute the following:
select dateadd(dd,92710,1/1/1753)
I get 2153-10-31 00:00:00.000
in managed code I get the right answer 11/1/2006. Between 1753 and 2007, there should have been 2007 - 1753 = 254 yrs x approx 365 = 92,710 days. Where is the year 2153 coming from?

I am not sure if this is the correct forum but here goes!
We rebuilt our SqlServer 2000 Trans replication the other night. It used to run in 3 hours but now it runs in 9.5 hours (7 hours bcp out, 2.5 hours bcp in). We have a dedicated distributor box (4 processors), a 4 processor publisher, and a 2 processor subscriber. None of the systems exhibited any processor stress or unusual disk activity. The network tests OK (tested with file xfers). But the bcp's wrote data at 2.5 to 4 minutes per 100k rows, and they loaded the data at about 100k rows in 10 seconds or less.
As you know, Replication Snapshot uses bcp on each source table to build a collection of flat-files. Then it uses bcp to load those files into the subscribing tables. Because bcp is the workhhorse here, I decided against posting this in the Replication forum.
The only change I know of is increasing MaxBcpThreads from 4 to 8. This parameter specifies the number of bulk-copy operations that can be performed in parallel. I was thinking that 8 bcp's might somehow be killing the drive where all the bcp files are written.
Any ideas?

I installed SP2 two days ago and it seems like my SSIS-packes now take longer time than before - the very opposite of what I was hoping for.
Anyway, here are some data from runs on our performance environment. No new data is added to the source database between the runs, but I do a full process of the cubes every time (time is in seconds):
Package...............................SP1...............................SP2
Load dimensions..................200.................................270
Load fact data.......................800...............................1600
Process cubes....................2100...............................2600
So, as you can see, everything is going slower with SP2. I have yet to look into if there are any specific steps in the packages that take longer time than before, but it's odd that all packages take a longer time to execute. Especially that cube processing is slower suprises me.
Has anyone experienced something similar? Thanks!

Hi, I have a problem with working out some dates. I have a query that has a start date field and a number of days field. I know i can create another field that could provide the return date (DATEADD function) by adding the number of days to the start date. However the problem I have is that i need to discount the weekends from the return date. For example if the start date was a wednesday and the number of days was 3 the datadd sum would give a return date of saturday when in reality it should be monday. I am not sure if i am making sense but if anyone out there has any ideas it would be more than welcome. Andrew

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 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

I'm using a query that is not retrieving all of the data it should because of the datetime stamp. If I use the following in the where clause:
{table.date} between '4/1/2008' and dateadd(day, 1 '4/30/2008')
that works fine for April but not for other months, where I might get more data from the following month than I should.
Is there a way to add hours, minutes, and seconds (23:59:59), all at the same time, without moving ahead an entire day?

I am trying to find a group of clients that were entered last week. I am getting all the dates to go with the Monday of the week they were entered. i.e. If they were entered on 8-2 or 8-3, they go with 8-1. If they were entered, 8-9, they will be under the 8-8 Monday.
No problem with finding the Mondays using either the nice 'weekcommence' function I found here or using numerous t-sql examples.
One thing I don't understand is- how come I can't use an equal sign in my syntax?
For instance,
SELECT dbo.weekcommence(date_added)
FROM clients
where dbo.weekcommence(date_added) = dateadd(wk, -2, GETDATE() )
won't return any results. If I use a greater than sign, I get this week, 8-8 and last week 8-1. I only want to see the week of 8-1.
Now- look at what I have below: Shouldn't I really be able to see ONLY last week's Mondays with this?
select dateadd(wk, -2, dbo.weekcommence(date_added))from clients
To me- the way this reads is: show me 2 weeks ago, from these dates (first Mondays function).
The results are the last two MONTHS, not weeks. What am I misinterpreting?
I can also use this:
SELECT dbo.weekcommence(date_added) FROM clients
WHERE (dbo.weekcommence(date_added) >= dateadd("d",-7,DATEADD(wk, DATEDIFF(wk,1,getdate()), 0)))
and get the week's of 8-1 and 8-8. But I can't get JUST 8-1 if I take out the greater than sign.
To me- this one reads: Select all my Mondays from the function. Show me Mondays from my function that are = 7 days from this Monday's date.
It seems like it should be straightforward, but I'm obviously missing something big. Any help?

I have a bigint column called "MillisecondsSince1970" that I need to convert to a date - SSIS is erroring out when I use DATEADD with the 8 byte int (if I use 4 byte it works but the column is bigger than 4 byte). The error is really lame:
[Derived Column [79]] Error: The "component "Derived Column" (79)" failed because error code 0xC0049067 occurred, and the error row disposition on "output column "Date" (100)" specifies failure on error. An error occurred on the specified object of the specified component.
Anyone have a way around it... a VB.NET equivalent of DATEADD or something else I can do?

Problem:
I have two nearly identical querys that are running. One of the query's is using the SQL DATEADD function. These query's are running on a SLQ2005 MSDE. There is now service pack four applied to this server.
The question is:
Are there any known issues with the DATEADD function in SQL 2005? This query is used in a report that has been in use for about two years. There were some changes made to the server (BIOS upgrade) including adding this service pack. These changes did not cause any other SQL issues. This query now takes almost five minutes to run. The nearly identical query (the difference is the date is passed in as a parameter rather than using the DATEADD function) takes from one to two seconds. These reports have a history of nearly identical running time.
What is a good way to try and correct the issue or at least to try and isolate the problem? Have there been any known issues with this function?
Thanks for any help!

Heres My SQL to get me 2 hours back of Midnight, two months ago (so 11pm of the prev day)
SELECT DATEADD("hh",-2,DATEADD("m",-2,DATEADD(dd,-(DAY(GetDate())-1),DATEADD(day,DATEDIFF(day, 0, GETDATE()),0))))
So I converted it into RS for my report start date, but it's not running...cant even get preview to load, it detects an error right away.,,just doesnt tell me what it is
=DATEADD("h",-2,DATEADD("m",-2,DATEADD("d",-(DAY(Now())-1),DATEADD("d",DATEDIFF("d", 0, Now()),0)))
I'm pretty sure I have the "h", "m" and "d" syntax right, I tried them all individually and they give me the correct dates...other than changing GetDate() to Now() I dont know what makes this diffenent...is it just too much nesting to Reporting Services?

How was the DATEDIFF function written? I would like to know the logic behind it.
Also what does it mean to say
SELECT DATEDIFF(MONTH, 30, '2004-12-30')
I thought it accepts two dates only. but instead, it took 30 as start date and returned 1259!!

Hi gurus
I haven't put the code in since I've tried several variations & keep having the same problem: I'm hoping someone will recognise the problem from a description of it.
There are two parts to my query.
* Part 1 creates and then populates a temporary table
* Part 2 is a select query which joins the temporary table to a permanent table, on 2 fields including a datetime field. The data types on each side of the join are identical.
If I run the first part of the query through ISQL and wait for it to complete before running the second part (in the same ISQL window), it (the second part) takes just 3 minutes. However, if I run both parts together, the second part takes ages, in fact I'm not sure if it completes at all (could wait indefinately!).
I tried placing a 'GO' between the two queries when running them together, but it didn't seem to help.
Please help, I'm stumped.
Thanks

I am new to SSIS and probably doing some mistake while transferring data from oracle source to oracle destination. Please guide me.. In our project we need to transfer nearly 80 GB data from old system (Oracle 9i) to new system (Oracle 10 G Release 2). To do this exercise we are testing and comparing performance and cost effectiveness between different tools like SSIS, DTS and SQL * Loader (oracle built in tool). We have selected one table, which is having 40 fields with 3 million records. The destination table is also having same structure. Surprisingly SSIS is giving slower performance than DTS!!!!! It is taking more than two hours or nearly two hours. I have tested the same process 3 times. I have used two servers (1 GB RAM, Dual processor) for source and destination with minimum load and used data flow task (OLEDB Source and OLEDB Destination). In case of transferring data from Oracle to SQL SERVER I am finding €śFast Loading Option€? in data access mode, which is giving considerable performance boosting. But while transferring data from Oracle to Oracle I am not finding €śFast Loading Option€? !!!!!!!!! For performance boosting which provider I should use?? Please suggest me€¦ if any one can€¦ would remain grateful to him€¦ Thanks and Regards Sudripta Rakshit.
