DATEPART not working like i think it must - sql

select *
from Advertisements
where DepartureDate < DATEPART('dd.mm.yy', '09.10.2010');
but i get
Msg 1023, Level 15, State 1, Line 1
Invalid parameter 1 specified for datepart.
in plsql is this very simple here is so complicated...
Can someone tell me please how can i get all dates that are smaller than today.

You can use this to get the current date:
CONVERT(date, GETDATE())
See the documentation.

SELECT *
FROM Advertisements
WHERE DepartureDate < CONVERT(date, GETDATE())

You seem to be confusing DATEPART with FORMAT_DATE (which does not exist anyway).
DATEPART extracts certain part of a date. Exactly one part.
Dates that are smaller than today are < dbo.CropTime(getdate()), where CropTime is a function which can be written in different ways (such as those described in this question).
Or, in case you are using SQL Server 2008, it's as simple as < cast(getdate() as date).

Would that code really work in PL/SQL? The DATEPART in T-SQL function is used to extract individual portions of a date.
This will get you all the dates before now.
select * from Advertisements where DepartureDate < getdate()
If you're planning to hardcode the date (as your sample code suggests), you just need to format in a way that SQL Server will understand. eg.
select * from Advertisements where DepartureDate < '2010-10-09'
I've been told that date format works on every server regardless of its localization settings. It's certainly worked on every server I've tried it on - but I'm happy to be overruled :-)

What you are looking for I think is
select *
from Advertisements
where DepartureDate < Convert(Date, '09.10.2010', 102)
or possibly
SELECT *
FROM Advertisements
WHERE DepartureDate < Cast(CURRENT_TIMESTAMP as date)

DatePart is used for getting components of the date such as the month, year or day. To get dates that are smaller (older) than now I would do this.
select * from Advertisements where DepartureDate < GetDate();
If I wanted Departure dates that were yesterday or before I could do this.
select * from Advertisements where DepartureDate < Convert(DateTime,Convert(Char(10),GetDate(),121));
or
select * from Advertisements where DepartureDate < Convert(DateTime,floor(convert(int,GetDate())))

SQL: Trying to select records 7 days before date

I have a table with a date field called oppo_installdate. This is a date in the future, and I basically want to select records where this date is 7 or fewer days from the current date. I have tried to do this with the query below but it is older returning dates from 2019 as well, and I'm not sure why that's happening.
select * from [CRM_Test].[dbo].[Opportunity]
where (GETDATE() >= DATEADD(day,-7, oppo_installdate))
Could anyone suggest a better way of doing this?
Whenever you're using a WHERE always try to apply any functions to constants, or other functions, never your columns. DATEADD(day,-7, oppo_installdate) will make the query non-SARGable, and could slow it down as any indexes won't be able to be used.
It seems like what you simply want is:
SELECT *
FROM [dbo].[Opportunity]
WHERE oppo_installdate >= DATEADD(DAY, 7, GETDATE());
Note that GETDATE returns a datetime, so if you want from midnight 7 days ago, you would use CONVERT(date,GETDATE()) (or CAST(GETDATE() AS date)).
Use below condition-
select * from [CRM_Test].[dbo].[Opportunity]
where oppo_installdate>= DATEADD(day,-7, GETDATE()) and oppo_installdate<=getdate()
This should give you the records where oppo_installdate is 7 or fewer days away from now:
SELECT *
FROM [dbo].[Opportunity]
WHERE oppo_installdate <= DATEADD(DAY, 7, GETDATE())
and oppo_installdate > getdate();

SQL Server comparing dates

I have a table with Settlement details and I need a report in SSRS that returns settlement items with settlement date yesterday or older. I know this is trivial but there is something I am doing wrong and would appreciate help
This is for Microsoft SQL Server and basic table for simplification
Select
SETL.SettlementDay as SD,
SETL.Amount as Amount,
SETL.quantity as Q
From
Setlement as SETL
Where
SETL.SettlementDate < getdate()
This doesn't work for me. I expect the output would be settlements with settlement date older or equal to yesterday
Thanks
If you want yesterday or older, then use:
where SETL.SettlementDate < convert(date, getdate())
The conversion to date gets rid of the timestamp on getdate() (despite the name, it has the time as well as the date).
You might find this less confusing if you use current_timestamp (which is part of the SQL standard):
where SETL.SettlementDate < convert(date, current_timestamp)
could you try by using cast
Select
SETL.SettlementDay as SD,
SETL.Amount as Amount,
SETL.quantity as Q
From
Setlement as SETL
Where
cast( SETL.SettlementDate as date) < cast( getdate() as date)

SQL Server : select count of Todays Transactions

I was wondering if someone could help me as I can't seem to find an answer to the following that I have been searching for.
Select
Count(pm1.number) As number
From
SCenter.probsummarym1 As pm1
Where
pm1.open_time >= Today()
I have the above that works great if I put in the date as '01-05-2015'
But I want today's date each day when it refreshes.
Sorry if this is pretty basic but I am just lost on this one
GETDATE() will return the current date and time.
You may then use a CAST() or CONVERT() to strip the time value and be left with just the date, ie.
SELECT CONVERT(VARCHAR(10), GETDATE(), 110)
The above code would return 05-19-2015 for today.
Select
Count(pm1.number) As number
From SCenter.probsummarym1 As pm1
Where
pm1.open_time >= GETDATE() //or CONVERT(VARCHAR(10), GETDATE(), 110)

sql compare datetime today

I hope anyone can translate my abstract query.
I want to select * from TABLE where ( [MYDATETIMEROW] < (TODAY - 3 Days)).
Does I have to Convert, cast or use datepart or anything else?.. im confused.
Are there simple rules? I would'nt have problems to do that with linq but simple sql I learned just hardly.
Thank you and best regards.
In simple terms:
Select * from Table where MyDateTimeRow < dateadd(dd,-3,getdate())
But using getdate() will provide both a date and a time, experience says that this is unlikely to be exactly what you want - you might want to strip the time down and just consider the date portion
Select * From Table where MyDateTimeRow < dateadd(dd, datediff(dd, 0, getdate()) - 3, 0)
You want the DateAdd function to manipulate dates and the GetDate function to get the current date:
SELECT * FROM MyTable WHERE [MyDateTimeRow] < DateAdd(dd, -3, GetDate())

SQL Server: Get data for only the past year

I am writing a query in which I have to get the data for only the last year. What is the best way to do this?
SELECT ... FROM ... WHERE date > '8/27/2007 12:00:00 AM'
The following adds -1 years to the current date:
SELECT ... From ... WHERE date > DATEADD(year,-1,GETDATE())
I found this page while looking for a solution that would help me select results from a prior calendar year. Most of the results shown above seems return items from the past 365 days, which didn't work for me.
At the same time, it did give me enough direction to solve my needs in the following code - which I'm posting here for any others who have the same need as mine and who may come across this page in searching for a solution.
SELECT .... FROM .... WHERE year(*your date column*) = year(DATEADD(year,-1,getdate()))
Thanks to those above whose solutions helped me arrive at what I needed.
Well, I think something is missing here. User wants to get data from the last year and not from the last 365 days. There is a huge diference. In my opinion, data from the last year is every data from 2007 (if I am in 2008 now). So the right answer would be:
SELECT ... FROM ... WHERE YEAR(DATE) = YEAR(GETDATE()) - 1
Then if you want to restrict this query, you can add some other filter, but always searching in the last year.
SELECT ... FROM ... WHERE YEAR(DATE) = YEAR(GETDATE()) - 1 AND DATE > '05/05/2007'
The most readable, IMO:
SELECT * FROM TABLE WHERE Date >
DATEADD(yy, -1, CONVERT(datetime, CONVERT(varchar, GETDATE(), 101)))
Which:
Gets now's datetime GETDATE() = #8/27/2008 10:23am#
Converts to a string with format 101 CONVERT(varchar, #8/27/2008 10:23am#, 101) = '8/27/2007'
Converts to a datetime CONVERT(datetime, '8/27/2007') = #8/27/2008 12:00AM#
Subtracts 1 year DATEADD(yy, -1, #8/27/2008 12:00AM#) = #8/27/2007 12:00AM#
There's variants with DATEDIFF and DATEADD to get you midnight of today, but they tend to be rather obtuse (though slightly better on performance - not that you'd notice compared to the reads required to fetch the data).
Look up dateadd in BOL
dateadd(yy,-1,getdate())
GETDATE() returns current date and time.
If last year starts in midnight of current day last year (like in original example) you should use something like:
DECLARE #start datetime
SET #start = dbo.getdatewithouttime(DATEADD(year, -1, GETDATE())) -- cut time (hours, minutes, ect.) -- getdatewithouttime() function doesn't exist in MS SQL -- you have to write one
SELECT column1, column2, ..., columnN FROM table WHERE date >= #start
I, like #D.E. White, came here for similar but different reasons than the original question. The original question asks for the last 365 days. #samjudson's answer provides that. #D.E. White's answer returns results for the prior calendar year.
My query is a bit different in that it works for the prior year up to and including the current date:
SELECT .... FROM .... WHERE year(date) > year(DATEADD(year, -2, GETDATE()))
For example, on Feb 17, 2017 this query returns results from 1/1/2016 to 2/17/2017
For some reason none of the results above worked for me.
This selects the last 365 days.
SELECT ... From ... WHERE date BETWEEN CURDATE() - INTERVAL 1 YEAR AND CURDATE()
The other suggestions are good if you have "SQL only".
However I suggest, that - if possible - you calculate the date in your program and insert it as string in the SQL query.
At least for for big tables (i.e. several million rows, maybe combined with joins) that will give you a considerable speed improvement as the optimizer can work with that much better.
argument for DATEADD function :
DATEADD (*datepart* , *number* , *date* )
datepart can be: yy, qq, mm, dy, dd, wk, dw, hh, mi, ss, ms
number is an expression that can be resolved to an int that is added to a datepart of date
date is an expression that can be resolved to a time, date, smalldatetime, datetime, datetime2, or datetimeoffset value.
declare #iMonth int
declare #sYear varchar(4)
declare #sMonth varchar(2)
set #iMonth = 0
while #iMonth > -12
begin
set #sYear = year(DATEADD(month,#iMonth,GETDATE()))
set #sMonth = right('0'+cast(month(DATEADD(month,#iMonth,GETDATE())) as varchar(2)),2)
select #sYear + #sMonth
set #iMonth = #iMonth - 1
end
I had a similar problem but the previous coder only provided the date in mm-yyyy format. My solution is simple but might prove helpful to some (I also wanted to be sure beginning and ending spaces were eliminated):
SELECT ... FROM ....WHERE
CONVERT(datetime,REPLACE(LEFT(LTRIM([MoYr]),2),'-
','')+'/01/'+RIGHT(RTRIM([MoYr]),4)) >= DATEADD(year,-1,GETDATE())
Here's my version.
YEAR(NOW())- 1
Example:
YEAR(c.contractDate) = YEAR(NOW())- 1
For me this worked well
SELECT DATE_ADD(Now(),INTERVAL -2 YEAR);
If you are trying to calculate "rolling" days, you can simplify it by using:
Select ... FROM ... WHERE [DATE] > (GETDATE()-[# of Days])
