select month and year from Date of birth IN sql - sql

i have table with DOB column ('2012-05-29 00:00:00.000') and few other fields , i need to select the data for DOB between 6 months to 6 Years. I tried using the below SQL but this is not giving me the right data. any help will be appreciated.
select * from dbo.xyz
where ( FLOOR(DATEDIFF(MONTH, birth_date , GETDATE()) % 12) >=6
AND FLOOR(DATEDIFF(DAY, birth_date , GETDATE()) / 365.25) <= 6
)

When using dates, the advice is to use functions only on the non-column values. In other words, modify getdate(), not birth_date:
select *
from dbo.xyz
where birth_date between dateadd(year, -6, getdate()) and dateadd(month, -6, getdate())
This has two advantages. First, it makes the where clause "sargable", which means an index can be used on the comparison. More importantly, the alternative of using datediff() doesn't quite work as expected. datediff() counts the number of calendar boundaries between two values. So, 2014-12-31 and 2015-01-01 are one day apart, one month apart, and even one year apart.

Try this
select * from dbo.xyz
where DATEDIFF(MONTH, birth_date , GETDATE()) between 6 and 72

Here is another option that will allow indexing on birthdate.
select *
from dbo.xyz
where birthdate > DATEADD(YEAR, -6, GETDATE())
and birthdate < DATEADD(MONTH, -6, GETDATE())

How to go back two days from a date in sql?

I wrote an SQL query that allows me to get the sales of certain stores.
My query runs every mornings and I would like to get the sales from 2 days ago at runtime.
For example if my query runs tomorrow morning, on 08/12, I would like to have the sales whose value in the column "GP_HEURECREATION" starts with "20200612", to have all the sales of the whole day.
The GP_HEURECREATION column has a format like this: "20200612 00:00:00" and is of the DATE type.
I tried with NOW() and DATEADD() but I have 2018 values that stand out for example.
How can I get the values only two days before the query is executed?
SELECT
T_ETABLISSEMENT, ET1.ET_LIBELLE AS C1, GL_ETABLISSEMENT,
GP_HEURECREATION, GP_REFINTERNE, GL_CODEARTICLE,
LIBDIM2, LIBDIM1, GL_QTEFACT, GL_PUTTC,
(GL_TOTALHT * GP_COTATIONDOS) AS TOTALHTDEV, GL_DPR, GL_DEVISE,
GL_NATUREPIECEG, GA_LIBELLE
FROM
GCLIGNEARTDIM
LEFT OUTER JOIN
PGI_LOOKUP(TTETABLISSEMENT) ET1 ON GL_ETABLISSEMENT = ET1.ET_ETABLISSEMENT
WHERE
(GP_HEURECREATION <= DATEADD(day, -2, GETDATE())
AND (GL_NATUREPIECEG = "FFO")
AND GL_ETABLISSEMENT = "20897", "10519", "20267", "26451", "20269", "26078", "28047", "20900", "28085", "24984", "27113", "20268", "19994", "28450", "26876", "24063", "18066", "3220"
ORDER BY
GP_REFINTERNE
The syntax of your existing query suggests SQL Server. If you want records that belong to day -2, you can do:
where gp_heurecreation >= dateadd(day, -2, convert(date, getdate()))
and gp_heurecreation < dateadd(day, -1, convert(date, getdate()))
If gp_heurecreation has no time component (in SQL Server, that's a date datatype), this is simpler:
where gp_heurecreation = dateadd(day, -2, convert(date, getdate()))

Getting the week number as alias in sql analysis

this is my first question here. Hopefully I´m clear enough what I´m searching for.
My problem is following:
On this analysis I want to get from the last 7 weeks, the summarized prices of each week. Its working with out any problems, but now I would like to add the weeks number of each week as alias.
In my tests I was using for example something like this:
DECLARE #week7 varchar(10)
SET #week7 = DATEPART(wk, GetDate())
One of my problems is, that I´m not allowed to work with "EXEC".
This is just an example of my analysis:
SELECT DISTINCT(
SELECT SUM(Price)
FROM tblBookingdata
WHERE(Datum BETWEEN DATEADD(wk, -7, DATEADD(DAY, 1 - DATEPART(WEEKDAY, GETDATE()), DATEDIFF(dd, 0, GETDATE()))) AND DATEADD(wk, -6, DATEADD(DAY, 1 - DATEPART(WEEKDAY, GETDATE()), DATEDIFF(dd, 0, GETDATE()))))) AS '7 weeks ago', (
SELECT SUM(Price)
FROM tblBookingdata
WHERE(Datum BETWEEN DATEADD(wk, -6, DATEADD(DAY, 1 - DATEPART(WEEKDAY, GETDATE()), DATEDIFF(dd, 0, GETDATE()))) AND DATEADD(wk, -5, DATEADD(DAY, 1 - DATEPART(WEEKDAY, GETDATE()), DATEDIFF(dd, 0, GETDATE()))))) AS '6 weeks ago'
I would like the column name to show the week number from each sub select. That the output would be for example for this week: 40 (as column name) and 900 as price summary.
So I tried to work here with DECLARE and assign #week7 for example with the current week number. But here I got stuck, due it seems like I need to work here with EXEC.
Is this only possible with "EXEC" or are there any other solutions to solve this? I was looking in the www, but currently I´m stucking a bit. Thankful for every help! :)
I think the DateDiff function is your friend here. Are you using SQL Server? This won't display a row for the week if there are zero records in that week, but this should be close to what you want.
select WeeksAgo, sum(Price) as Price from (
select
Price
,Datediff(wk, Datum, getDate()) as WeeksAgo
,Datum --not used
from
tblBookingdata
)DataByWeek
where WeeksAgo between 0 and 7 --should this be 0-6?
group by WeeksAgo
I think you're looking for something like this. The prior 7 weeks are calculated from GETDATE based on a numbers table with 1, 2, 3, ... 7. Then the booking Prices are summarized by week where the Datum is within the prior 7 weeks. This will display NULL in price_sum if there were no sales that week.
drop table if exists #tblBookingdata;
go
create table #tblBookingdata(
Datum date not null,
Price int not null);
go
;with
weeks_cte(wk) as (
select datepart(wk, dateadd(wk, w*-1, getdate()))
from (values (1),(2),(3),(4),(5),(6),(7)) v(w)),
bookings_cte(wk, price_sum) as (
select datepart(wk, Datum), sum(Price)
from #tblBookingdata
where Datum>dateadd(wk, -7, getdate())
group by datepart(wk, Datum))
select *
from weeks_cte wc
left join bookings_cte b on wc.wk=b.wk;

Trying to get an SQL command that gets the new customers from each month but i cant seem to get it working

I am trying to pull the new customers from each month from an SQL database. I've tried this:
SELECT COUNT (Name)
FROM Customer
WHERE Date_created BETWEEN CONVERT(date, getdate()) AND CONVERT(date, getdate()) - (30)
From your query I think this would do it simpler :
SELECT COUNT (Name) FROM Customer WHERE MONTH(Date_created)= MONTH(GETDATE())
although am not sure this is what you expect as your question could be interpreted in several ways
Edit : taking account of different years:
SELECT COUNT (Name) FROM Customer
WHERE MONTH(Date_created)= MONTH(GETDATE())
AND YEAR(Date_created)= YEAR(GETDATE())
Standard SQL:
select
extract(year from Date_created) as yr
,extract(month from Date_created) as mth
,count(*)
from Customer
group by
extract(year from Date_created) as yr
,extract(month from Date_created) as mth
order by yr, mth
Replace EXTRACT with a matching function in you DBMS, e.g. for SQL Server datepart(year, date)
You could use convert(varchar(6), getdate(), 112) to get the month in yyyymm format:
SELECT convert(varchar(6), getdate(), 112) as Month
, count(*)
FROM Customer
GROUP BY
convert(varchar(6), getdate(), 112)
I'm not a fan of using BETWEEN with dates (see this blog What do BETWEEN and the Devil Have in Common). However, the problem with your query is that the dates are in the wrong order. The smaller value has to go first:
SELECT COUNT(Name)
FROM Customer
WHERE Date_created BETWEEN CONVERT(date, getdate() - 30) AND CONVERT(date, getdate())
This is better written as :
SELECT COUNT(Name)
FROM Customer
WHERE Date_Created >= CONVERT(date, getdate() - 30) AND
Date_Created < CONVERT(date, getdate());
I'm not sure if this satisfies your definition of "month", but at least the query will return 30 days worth of creates.

SQL Server 3 month from now

I need a SQL select statement to retrieve all employees that their enddate contract will end three month from now and only three month not more or less
It depends what you mean by 3 months from now. If you mean on that exact date, then:
WHERE my_date_column = cast(dateadd(month, 3, getdate()) as date)
Note the cast to date to remove the time component. This is ambiguous and under some circumstances might miss employees or count them twice.
If you want employees whose contract ends in the 3rd month from today, then use:
WHERE DATEDIFF(month, getdate(), my_date_column) = 3
So, if this is January, this will return employees whose contract ends any time in April.
SELECT *
FROM TABLE_NAME
WHERE Date_Column >= DATEADD(DAY, +90, GETDATE())
OR
SELECT *
FROM TABLE_NAME
WHERE Date_Column >= DATEADD(MONTH, +3, GETDATE())
OR
SELECT *
FROM TABLE_NAME
WHERE DATEDIFF(MONTH, my_date_column, GETDATE()) <= 3

get todays date with last 6 months back

I want the exact date as 22/06/2015 from the query
whose Joining date should be exact
22/06/2015
which is exact 6 months back from todays date
I tried like below
Select date_of_joining,* from emp_mst Where Dt_Of_Join >= Dateadd(Month, Datediff(Month, 0, DATEADD(m, -6, getdate())), 0)
but it didn't worked.
what is the exact query for that ?
I am using SQL- server- 2005
if you want the EXACT joining date ( /date_of_joining.... /Dt_Of_Join)
what about
select distinct employee.name from emp_mst where date_of_joining = DATEADD(month, -6, GETDATE())
or if you want the actual date returned in a different format:
CONVERT(Date,DATEADD(month, -6, GETDATE()), 103)
which is applicable if you select this field
I'm not a SQL Server guru, but I found easy answers everywhere for this.
Try this link to another post which explains this exact question SQL Server 2005: how to subtract 6 month
You refer to the word "exact" date, so you don't need the datediff section, you can just subtract 6 months from the current date using "dateadd" which will give you a precise date. Just remember to correctly type cast else you will have to be accurate to the millisecond.
SELECT employee_name
FROM emp_mst
WHERE Dt_Of_Join = Cast(DATEADD(month, -6, GETDATE()) As Date)
ORDER BY Dt_Of_Join DESC
I think he just need to know how to remove time from date
Note that you need to handle time part effectively
Select * from emp_mst
Where
Dt_Of_Join >= dateadd(month,-6,dateadd(day,datediff(day,0,getdate()),0)
and
Dt_Of_Join < dateadd(month,-6,dateadd(day,datediff(day,0,getdate()),1)
You want previous 6 month date so use dateadd() and for your date formate DD/MM/YYYY you should try to convert(varchar(10),date,101).
Select date_of_joining,* from emp_mst Where
Dt_Of_Join=convert(varchar(10),dateadd(month,-6,getdate()),101)
