How do I find data from this day exactly one year ago? - sql

Right now I have:
year(epe_curremploymentdate) = year(DATEADD(year, -1, SYSDATETIME()))
But that is giving me everything from last year. All I want is the data from today's date, one year ago.


It should be:
epe_curremploymentdate = DATEADD(year, -1, GETDATE())
Don't check for year in your where clause.
EDIT:
Simple: use
cast(epe_curremploymentdate AS DATE) = cast(DATEADD(year, -1,
GETDATE()) AS DATE)
That is, if you are using SQL Server 2008 and above.


This should get you to where you need to go:
Declare #StartDate datetime, #EndDate datetime
-- #StartDate is midnight on today's date, last year
set #StartDate = Convert(date, (DATEADD(year, -1, getdate())))
set #EndDate = DATEADD(Day, 1, #StartDate)
select *
from YourTable
where epe_curremploymentdate >= #StartDate
and epe_curremploymentdate < #EndDate
-- This where clause will get you everything that happened at any time
-- on today's date last year.


Date today:
select getdate()
date one year ago:
select dateadd(year, -1, getdate())
Date one year and one day ago:
select dateadd(d, -1 , dateadd(year, -1, getdate()))
UPDATE:
select *
from
epe_curremploymentdate = dateadd(year, -1, CAST(FLOOR(CAST(GETDATE() AS FLOAT)) AS DATETIME))
This will give you a list of all employees who started working exactly from a year ago.
Hope this helps!!!


If you have other fields that show as datetime with the time part as 00:00:00.000, to do joins you can use the below
dateadd(yy,-1,datediff(d,0,getdate()))


epe_curremploymentdate = DATEADD(year, -1, GETDATE())

Get data from last month in SQL Server

I checked Get the records of last month in SQL server and it did not work!
I try to get the records of last month based on my database table and column issue_date.
What's the SQL query to do this?
For clarification, today (27-April-18) I want to get all records from March-18.
I have the issue_date in the format that I convert to date but below code gives me all records from 01-March-2018 to and including today.
DATEPART(month, CONVERT (VARCHAR(11),DATEADD(day,wo_header.issue_date,`1971/12/31`),106)) = DATEPART(month, DATEADD(month, -1, getdate()))

To get firstDay and lastDay of previous month
DECLARE #FirstDayOfLastMonth DATETIME = CONVERT(DATE, DATEADD(d, -(DAY(DATEADD(m, -1, GETDATE() - 2))), DATEADD(m, -1, GETDATE() - 1))),
#LastDayOfLastMonth DATETIME = CONVERT(DATE, DATEADD(d, -(DAY(GETDATE())), GETDATE()))
SELECT #FirstDayOfLastMonth, #LastDayOfLastMonth
Your required Query
SELECT *
FROM TABLE
WHERE CAST(issue_date AS DATE) BETWEEN CONVERT(DATE, DATEADD(d, -(DAY(DATEADD(m, -1, GETDATE() - 2))), DATEADD(m, -1, GETDATE() - 1))) AND CONVERT(DATE, DATEADD(d, -(DAY(GETDATE())), GETDATE()))

Perhaps the easiest method is eomonth(). If there is no time component on issuedate:
where issuedate > eomonth(getdate(), -2) and
issuedate <= eomonth(getdate(), -1)
If there is a time component:
where issuedate >= dateadd(day, 1, cast(eomonth(getdate(), -2) as date)) and
issuedate < dateadd(day, 1, cast(eomonth(getdate(), -1) as date))
Without eomonth, I would do:
where issuedate < cast(dateadd(day, 1 - day(getdate()), getdate()) as date) and
issuedate >= dateadd(month, -1, cast(dateadd(day, 1 - day(getdate()), getdate()) as date))

The code I figured out is not pretty but it works. It first adds extra column with the month number to the SELECT portion of my code:
Month(CONVERT (VARCHAR(11),DATEADD(day,wo_header.closing_date,'1971/12/31'),106)) As Month
And than is used for WHERE statement:
Month(CONVERT (VARCHAR(11),DATEADD(day,wo_header.closing_date,'1971/12/31'),106)) = month(getdate())-1
So for anyone like me working in SQL report kind-of environment it should work.

Getdate() functionality returns partial day in select query

I have a query -
SELECT * FROM TABLE WHERE Date >= DATEADD (day, -7, -getdate()) AND Date <= getdate();
This would return all records for each day except day 7. If I ran this query on a Sunday at 17:00 it would only produce results going back to Monday 17:00. How could I include results from Monday 08:00.

Try it like this:
SELECT *
FROM SomeWhere
WHERE [Date] > DATEADD(HOUR,8,DATEADD(DAY, -7, CAST(CAST(GETDATE() AS DATE) AS DATETIME))) --7 days back, 8 o'clock
AND [Date] <= GETDATE(); --now

That's because you are comparing date+time, not only date.
If you want to include all days, you can trunc the time-portion from getdate(): you can accomplish that with a conversion to date:
SELECT * FROM TABLE
WHERE Date >= DATEADD (day, -7, -convert(date, getdate())
AND Date <= convert(date, getdate());
If you want to start from 8 in the morning, the best is to add again 8 hours to getdate.
declare #t datetime = dateadd(HH, 8, convert(datetime, convert(date, getdate())))
SELECT * FROM TABLE
WHERE Date >= DATEADD (day, -7, -#t) AND Date <= #t;
NOTE: with the conversion convert(date, getdate()) you get a datatype date and you cannot add hours directly to it; you must re-convert it to datetime.

Sounds like you want to remove the time. Correct? If so then do the following.
SELECT * FROM TABLE WHERE Date >= (DATEADD (day, -7, -getdate()) AND Date DATEADD(dd, DATEDIFF(dd, 0, getdate()), 0))

Conditional where statement: select different time period when query date varies

I have a query need to select different time period. The logic is:
if today is Tuesday, select Saturday 00:00:00 ~ Monday 23:99;
if today is other weekdays, select the previous working day (00:00:00 ~ 23:99).
Here is the query I have:
Select *
From ...
WHERE
(DATENAME(DW,GETDATE())= 'Tuesday'
AND (<#SalesDate> BETWEEN DATEADD(DAY, -3, GETDATE()) and DATEADD(DAY, -1, GETDATE())))
OR
(DATENAME(DW,GETDATE())<> 'Tuesday'
AND (<#SalesDate> BETWEEN DATEADD(DAY, -1, GETDATE())and DATEADD(DAY, -1, GETDATE())))
It didn't return the result that I want. Anyone can help me? thank you.

BETWEEN is a bit finicky when it comes to date datatypes. See this question.
GETDATE() will return the time for today. You need to strips it off.
-- Today's date, stripped of time
DECLARE #Today datetime = CONVERT(datetime,CONVERT(date,GETDATE()))
Select *
From ...
WHERE
(DATENAME(DW,GETDATE())= 'Tuesday'
AND (#SalesDate >= DATEADD(DAY, -3, #Today) and #SalesDate < DATEADD(DAY, -1, #Today)))
OR
(DATENAME(DW,GETDATE())<> 'Tuesday'
AND (#SalesDate >= DATEADD(DAY, -1, #Today) and #SalesDate < DATEADD(DAY, -1, #Today)))

How do I compare against the current week using SQL Server?

How do I compare an SQL Server date column against the current week?
For instance:
WHERE [Order].SubmittedDate = *THIS WEEK*

You could convert your date to a week number and compare this to the week number from the current date. Likewise, you'll need to compare the year as well, so that you don't get last year's weeks.
WHERE DATEPART(wk, [Order].SubmittedDate) = DATEPART(wk, GETDATE())
AND DATEPART(yy, [Order].SubmittedDate) = DATEPART(yy, GETDATE())

Assuming you are meaning always "this week" and there are no records with Submitted dates in the future, which I imagine could be the case you can do:
WHERE [Order].SubmittedDate >= DATEADD(dd, -(DATEPART(dw, GETDATE()) -1), GETDATE())
If dates do go into the future, the full restriction to this week is:
WHERE [Order].SubmittedDate >= DATEADD(dd, -(DATEPART(dw, GETDATE()) -1), GETDATE())
AND [Order].SubmittedDate < CAST(CONVERT(VARCHAR(10), DATEADD(dd, (8 - DATEPART(dw, GETDATE())), GETDATE()), 120) AS DATETIME)
I'd strongly recommend using a clause based on a start and end date like this, as it will allow efficient index use so should perform better.

Try this:
WHERE [Order].SubmittedDate BETWEEN
DATEADD(d, - DATEPART(dw, GETDATE()) + 1, GETDATE()) AND
DATEADD(d, 7 - DATEPART(dw, GETDATE()) , GETDATE())
Maybe this can run faster, as doesn't needs to be evaluated everytime:
DECLARE #StartDate DATETIME,
#EndDate DATETIME
SELECT #StartDate = DATEADD(d, - DATEPART(dw, GETDATE()) + 1, GETDATE()),
#EndDate = DATEADD(d, 8 - DATEPART(dw, GETDATE()) , GETDATE())
-- // Strip time part, so week starts on Sunday 00:00
SELECT #StartDate = CAST(FLOOR(CAST(#StartDate AS FLOAT)) AS DATETIME),
#EndDate = CAST(FLOOR(CAST(#EndDate AS FLOAT)) AS DATETIME)
...
WHERE [Order].SubmittedDate >= #StartDate AND [Order].SubmittedDate < #EndDate

Get the records of last month in SQL server

I want to get the records of last month based on my db table [member] field "date_created".
What's the sql to do this?
For clarification,
last month - 1/8/2009 to 31/8/2009
If today is 3/1/2010, I'll need to get the records of 1/12/2009 to 31/12/2009.

All the existing (working) answers have one of two problems:
They will ignore indices on the column being searched
The will (potentially) select data that is not intended, silently corrupting your results.
1. Ignored Indices:
For the most part, when a column being searched has a function called on it (including implicitly, like for CAST), the optimizer must ignore indices on the column and search through every record. Here's a quick example:
We're dealing with timestamps, and most RDBMSs tend to store this information as an increasing value of some sort, usually a long or BIGINTEGER count of milli-/nanoseconds. The current time thus looks/is stored like this:
1402401635000000 -- 2014-06-10 12:00:35.000000 GMT
You don't see the 'Year' value ('2014') in there, do you? In fact, there's a fair bit of complicated math to translate back and forth. So if you call any of the extraction/date part functions on the searched column, the server has to perform all that math just to figure out if you can include it in the results. On small tables this isn't an issue, but as the percentage of rows selected decreases this becomes a larger and larger drain. Then in this case, you're doing it a second time for asking about MONTH... well, you get the picture.
2. Unintended data:
Depending on the particular version of SQL Server, and column datatypes, using BETWEEN (or similar inclusive upper-bound ranges: <=) can result in the wrong data being selected. Essentially, you potentially end up including data from midnight of the "next" day, or excluding some portion of the "current" day's records.
What you should be doing:
So we need a way that's safe for our data, and will use indices (if viable). The correct way is then of the form:
WHERE date_created >= #startOfPreviousMonth AND date_created < #startOfCurrentMonth
Given that there's only one month, #startOfPreviousMonth can be easily substituted for/derived by:
DATEADD(month, -1, #startOfCurrentMonth)
If you need to derive the start-of-current-month in the server, you can do it via the following:
DATEADD(month, DATEDIFF(month, 0, CURRENT_TIMESTAMP), 0)
A quick word of explanation here. The initial DATEDIFF(...) will get the difference between the start of the current era (0001-01-01 - AD, CE, whatever), essentially returning a large integer. This is the count of months to the start of the current month. We then add this number to the start of the era, which is at the start of the given month.
So your full script could/should look similar to the following:
DECLARE #startOfCurrentMonth DATETIME
SET #startOfCurrentMonth = DATEADD(month, DATEDIFF(month, 0, CURRENT_TIMESTAMP), 0)
SELECT *
FROM Member
WHERE date_created >= DATEADD(month, -1, #startOfCurrentMonth)
AND date_created < #startOfCurrentMonth
All date operations are thus only performed once, on one value; the optimizer is free to use indices, and no incorrect data will be included.

SELECT *
FROM Member
WHERE DATEPART(m, date_created) = DATEPART(m, DATEADD(m, -1, getdate()))
AND DATEPART(yyyy, date_created) = DATEPART(yyyy, DATEADD(m, -1, getdate()))
You need to check the month and year.

Add the options which have been provided so far won't use your indexes at all.
Something like this will do the trick, and make use of an index on the table (if one exists).
DECLARE #StartDate DATETIME, #EndDate DATETIME
SET #StartDate = dateadd(mm, -1, getdate())
SET #StartDate = dateadd(dd, datepart(dd, getdate())*-1, #StartDate)
SET #EndDate = dateadd(mm, 1, #StartDate)
SELECT *
FROM Member
WHERE date_created BETWEEN #StartDate AND #EndDate

DECLARE #StartDate DATETIME, #EndDate DATETIME
SET #StartDate = DATEADD(mm, DATEDIFF(mm,0,getdate())-1, 0)
SET #EndDate = DATEADD(mm, 1, #StartDate)
SELECT *
FROM Member
WHERE date_created BETWEEN #StartDate AND #EndDate
An upgrade to mrdenny's solution, this way you get exactly last month from YYYY-MM-01

Last month consider as till last day of the month.
31/01/2016 here last day of the month would be 31 Jan. which is not similar to last 30 days.
SELECT CONVERT(DATE, DATEADD(DAY,-DAY(GETDATE()),GETDATE()))

One way to do it is using the DATEPART function:
select field1, field2, fieldN from TABLE where DATEPART(month, date_created) = 4
and DATEPART(year, date_created) = 2009
will return all dates in april. For last month (ie, previous to current month) you can use GETDATE and DATEADD as well:
select field1, field2, fieldN from TABLE where DATEPART(month, date_created)
= (DATEPART(month, GETDATE()) - 1) and
DATEPART(year, date_created) = DATEPART(year, DATEADD(m, -1, GETDATE()))

declare #PrevMonth as nvarchar(256)
SELECT #PrevMonth = DateName( month,DATEADD(mm, DATEDIFF(mm, 0, getdate()) - 1, 0)) +
'-' + substring(DateName( Year, getDate() ) ,3,4)

SQL query to get record of the present month only
SELECT * FROM CUSTOMER
WHERE MONTH(DATE) = MONTH(CURRENT_TIMESTAMP) AND YEAR(DATE) = YEAR(CURRENT_TIMESTAMP);

SELECT * FROM Member WHERE month(date_created) = month(NOW() - INTERVAL 1 MONTH);

select * from [member] where DatePart("m", date_created) = DatePart("m", DateAdd("m", -1, getdate())) AND DatePart("yyyy", date_created) = DatePart("yyyy", DateAdd("m", -1, getdate()))

DECLARE #StartDate DATETIME, #EndDate DATETIME
SET #StartDate = DATEADD(mm, DATEDIFF(mm, 0, getdate()) - 1, 0)
SET #EndDate = dateadd(dd, -1, DATEADD(mm, 1, #StartDate))
SELECT * FROM Member WHERE date_created BETWEEN #StartDate AND #EndDate
and another upgrade to mrdenny's solution.
It gives the exact last day of the previous month as well.

WHERE
date_created >= DATEADD(MONTH, DATEDIFF(MONTH, 31, CURRENT_TIMESTAMP), 0)
AND date_created < DATEADD(MONTH, DATEDIFF(MONTH, 0, CURRENT_TIMESTAMP), 0)

I'm from Oracle env and I would do it like this in Oracle:
select * from table
where trunc(somedatefield, 'MONTH') =
trunc(sysdate -INTERVAL '0-1' YEAR TO MONTH, 'MONTH')
Idea: I'm running a scheduled report of previous month (from day 1 to the last day of the month, not windowed). This could be index unfriendly, but Oracle has fast date handling anyways.
Is there a similar simple and short way in MS SQL? The answer comparing year and month separately seems silly to Oracle folks.

You can get the last month records with this query
SELECT * FROM dbo.member d
WHERE CONVERT(DATE, date_created,101)>=CONVERT(DATE,DATEADD(m, datediff(m, 0, current_timestamp)-1, 0))
and CONVERT(DATE, date_created,101) < CONVERT(DATE, DATEADD(m, datediff(m, 0, current_timestamp)-1, 0),101)

I don't think the accepted solution is very index friendly
I use the following lines instead
select * from dbtable where the_date >= convert(varchar(10),DATEADD(m, -1, dateadd(d, - datepart(dd, GETDATE())+1, GETDATE())),120) and the_date <= dateadd(ms, -3, convert(varchar(10),DATEADD(m, 0, dateadd(d, - datepart(dd, GETDATE())+1, GETDATE())),120));
Or simply (this is the best).
select * from dbtable where the_date >= convert(varchar(10),DATEADD(m, -1, dateadd(d, - datepart(dd, GETDATE())+1, GETDATE())),120) and the_date < SELECT convert(varchar(10),DATEADD(m, -1, dateadd(d, - datepart(dd, GETDATE())+1, GETDATE())),120);
Some help
-- Get the first of last month
SELECT convert(varchar(10),DATEADD(m, -1, dateadd(d, - datepart(dd, GETDATE())+1, GETDATE())),120);
-- Get the first of current month
SELECT convert(varchar(10),DATEADD(m, -1, dateadd(d, - datepart(dd, GETDATE())+1, GETDATE())),120);
--Get the last of last month except the last 3milli seconds. (3miliseconds being used as SQL express otherwise round it up to the full second (SERIUSLY MS)
SELECT dateadd(ms, -3, convert(varchar(10),DATEADD(m, 0, dateadd(d, - datepart(dd, GETDATE())+1, GETDATE())),120));

Here is what I did so I could put it in a view:
ALTER view [dbo].[MyView] as
with justdate as (
select getdate() as rightnow
)
, inputs as (
select dateadd(day, 1, EOMONTH(jd.rightnow, -2)) as FirstOfLastMonth
,dateadd(day, 1, EOMONTH(jd.rightnow, -1)) as FirstOfThisMonth
from justdate jd
)
SELECT TOP 10000
[SomeColumn]
,[CreatedTime]
from inputs i
join [dbo].[SomeTable]
on createdtime >= i.FirstOfLastMonth
and createdtime < i.FirstOfThisMonth
order by createdtime
;
Note that I intentionally ran getdate() once.

In Sql server for last one month:
select * from tablename
where order_date > DateAdd(WEEK, -1, GETDATE()+1) and order_date<=GETDATE()

DECLARE #curDate INT = datepart( Month,GETDATE())
IF (#curDate = 1)
BEGIN
select * from Featured_Deal
where datepart( Month,Created_Date)=12 AND datepart(Year,Created_Date) = (datepart(Year,GETDATE())-1)
END
ELSE
BEGIN
select * from Featured_Deal
where datepart( Month,Created_Date)=(datepart( Month,GETDATE())-1) AND datepart(Year,Created_Date) = datepart(Year,GETDATE())
END

DECLARE #StartDate DATETIME, #EndDate DATETIME
SET #StartDate = dateadd(mm, -1, getdate())
SET #StartDate = dateadd(dd, datepart(dd, getdate())*-1, #StartDate)
SET #EndDate = dateadd(mm, 1, #StartDate)
set #StartDate = DATEADD(dd, 1 , #StartDate)

The way I fixed similar issue was by adding Month to my SELECT portion
Month DATEADD(day,Created_Date,'1971/12/31') As Month
and than I added WHERE statement
Month DATEADD(day,Created_Date,'1971/12/31') = month(getdate())-1

If you are looking for last month so try this,
SELECT
FROM #emp
WHERE DATEDIFF(MONTH,CREATEDDATE,GETDATE()) = 1
If you are looking for last month so try this,
SELECT
FROM #emp
WHERE DATEDIFF(day,CREATEDDATE,GETDATE()) between 1 and 30

A simple query which works for me is:
select * from table where DATEADD(month, 1,DATEFIELD) >= getdate()

If you are looking for previous month data:
date(date_created)>=date_sub(date_format(curdate(),"%Y-%m-01"),interval 1 month) and
date(date_created)<=date_sub(date_format(curdate(),'%Y-%m-01'),interval 1 day)
This will also work when the year changes. It will also work on MySQL.
