Filter results after date SQL Server - sql

I need to filter my query to extract the results between 25th of the previous month and 25th of the current month. The SP receives a date as parameter, which I am using to extract the current month.I tried to make some casting but I can't figure how to deal with the January month when the last month has a different year(there must be a more efficient way also)
#Date smalldatetime --received as parameter
select *
from mytable
where mytable.mydate between '25/'+cast(MONTH(#date)-1 as varchar(2))+'/'+cast(YEAR(#date) as varchar(4)) and '25/'+cast(MONTH(#date) as varchar(2))+'/'+cast(YEAR(#date) as varchar(4))


I would just do:
select t.*
from t
where mydate >= dateadd(month, -1, datefromparts(year(getdate()), month(getdate()), 25)) and
mydate < datefromparts(year(getdate()), month(getdate()), 25)
I would use datefromparts() rather than trying to construct a date string for this purpose.


You don't need to do any casting. SQL Server's datetime functions are quite versatile. Try this:
SELECT *
FROM mytable
WHERE mytable.mydate BETWEEN DATEADD(DAY, 25, DATEADD(MONTH, DATEDIFF(MONTH, 0, #Date) - 1, 0)) AND DATEADD(DAY, 25, DATEADD(MONTH, DATEDIFF(MONTH, 0, #Date), 0))

How to minus 2 month in SQL Server

My requirement is to make this query :
SELECT DATEADD(m, DATEDIFF(m, 0, GETDATE()), 0)
Minus by 2 months and the date should be stayed in 1.

Add DATEADD function on top of your existing query
SELECT DATEADD(MONTH,-2,DATEADD(M, DATEDIFF(M, 0, GETDATE()), 0)) --2016-05-01 00:00:00.000
If you are using SQL SERVER 2012+ the use EOMONTH function
SELECT DATEADD(DAY,1,EOMONTH(GETDATE(),-3)) --2016-05-01

In SQL Server, the following gets the first day of this month:
select cast(dateadd(day, 1 - day(getdate()), getdate()) as date)
For last month:
select dateadd(month, -1, cast(dateadd(day, 1- day(getdate()), getdate()) as date))
In SQL Server 2012+, you can also do:
select dateadd(month, -2, datefromparts(year(getdate()), month(getdate()), 1)
The use of adding months to a zero time is a hack before SQL Server had better date time functions.

T-SQL syntax to filter records where the datetime variable is greater than or equal to the 1st Day of the Current Month

I am using SQL Server 2014 and I need to add a line of code to my SQL query that will filter the data extracted only to those records where the StayDate (a column in database) is greater than or equal to the 1st day of the current month.
In other words, the line of code I need is the following:
WHERE StayDate >= '1st Day of Current Month'
Note: StayDate is in the datetime format (eg: 2015-12-18 00:00:00.000)

Use EOMONTH to get the first day of current month
WHERE StayDate >= Dateadd(dd, 1, Eomonth(Getdate(), -1))

SQL Server 2012 and above
WHERE StayDate >= DATEADD(DAY, 1, EOMONTH(GETDATE(), -1))
Before SQL Server 2012
WHERE StayDate >= DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE()), 0)

You can try following approach:
declare #t datetime = '2016-02-28'
select DATEADD(D, -DATEPART(d, #t) + 1, #t)
So in your case:
WHERE StayDate >= DATEADD(D, -DATEPART(d, GETDATE()) + 1, GETDATE())

StayDate >= DATEADD(MONTH, DATEDIFF(MONTH, '19000101', GETDATE()), '19000101')

One other option; since staydate being on or after (greater than or equal to) the first day of the current month is equivalent to searching for staydates during the current month:
where datepart(mm, staydate) = datepart(mm, getdate())
and datepart(yyyy, staydate) = datepart(yyyy, getdate())

Between Dates Where Clause With Shifting Date

Is it possible to do the following in SQL. I would like to write a code that will return records between certain dates, but will automatically update when the report runs. So for example:
on 12/18 I would like to return records from 11-1 to 11/18 and 12/1 to 12/18 so I can compare month over month on these records in my report.
I understand that I can do:
WHERE
[database] BETWEEN '2013-11-01' and DATEADD(Month, 1, getdate ()))
and not [database] IN ('2013-11-19 and '2013-11-30')
but I will have to go into the query everyday to update the not between. I would like to make it so that I can run the query on any day and get the records from the previous month up until the date match for this month. I currently have been working with this:
B.[datepaid] between DATEADD(Month, -1, getdate() )
and DATEADD(MONTH, 1, getdate() ))
but it is returning all records from November.

I would recommend against using BETWEEN with Dates as it can have some unexpected results. But in your case you can use:
WHERE ([Date] >= DATEADD(MONTH, DATEDIFF(MONTH, '19000101', GETDATE()) - 1, '19000101')
AND [Date] < DATEADD(MONTH, -1, GETDATE()))
OR ([Date] >= DATEADD(MONTH, DATEDIFF(MONTH, '19000101', GETDATE()), '19000101')
AND [Date] < GETDATE());

How to get 00:00:00 in datetime, for First of Month?

I wrote a query to obtain First of month,
SELECT DATEADD(DAY, -(DATEPART(DAY,GETDATE())-1), GETDATE()) as First_Of_Month;
for which i do get the appropriate output, but my time stamp shows the current time.
Here's what I am doing in the query, hope i make sense.
using datepart i calculated the no. of days (int) between the 1st and today (27-1 =26)
Then using dateadd function, i added "-datepart" to get the first of the month.
This is just changing the date, what should i look at or read about in order to change the time. I am assuming that it would have something to do with 19000101

For SQL Server 2012 (thanks adrift and i-one)
DECLARE #now DATETIME = CURRENT_TIMESTAMP;
SELECT DATEADD(DAY, 1, EOMONTH(#now, -1));
-- or
SELECT DATEFROMPARTS(YEAR(#now), MONTH(#now), 1);
For SQL Server 2008+
DECLARE #now DATETIME = CURRENT_TIMESTAMP;
-- This shorthand works:
SELECT CONVERT(DATE, #now+1-DAY(#now));
-- But I prefer to be more explicit, instead of relying on
-- shorthand date math (which doesn't work in all scenarios):
SELECT CONVERT(DATE, DATEADD(DAY, 1-DAY(#now), #now));
For SQL Server 2005
SELECT DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE()),0);
A caveat if you're using this SQL Server 2005 method: you need to be careful about using expressions involving DATEDIFF in queries. SQL Server can transpose the arguments and lead to horrible estimates - as seen here. It might actually be safer to take the slightly less efficient string approach:
SELECT CONVERT(DATETIME, CONVERT(CHAR(6), GETDATE(), 112) + '01');

SELECT convert(varchar(10),DATEADD(DAY, - (DATEPART(DAY,GETDATE())-1), GETDATE()),120)+' 00:00:00' as First_Of_Month;

Just the date
DATEADD(day, DATEDIFF(day, 0, GETDATE()), 0)
So for a month it is:
DATEADD(mm, DATEDIFF(mm, 0, GETDATE()), 0) AS FirstDatetimeOfMonthmm,

I think the easiest way is to cast the result to date:
SELECT cast(DATEADD(DAY, -(DATEPART(DAY,GETDATE())-1), GETDATE()) as date) as First_Of_Month

One alternative:
SELECT cast(
cast(datepart(yyyy, getdate()) as varchar)
+ '-'
+ cast(datepart(mm, getdate()) as varchar) + '-01 00:00:00'
as datetime)
Build up the date from year/month components, then tack on the 1st and midnight.

SELECT DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE()), 0) as First_Of_Month;

Try following code:
SELECT CAST(CAST(GETDATE() AS DATE) AS DATETIME) AS StartDateTime,
DATEADD(ms, -3, CAST(CONVERT(date, DATEADD (DAY,1,GETDATE())) AS varchar(10))) AS EndDateTime
Result:
StartDateTime
EndDateTime

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.
