I have a query in SQL Server that I want to run every week which would display the data from the last 7 days.
I tried using:
SELECT something FROM tbl_name
WHERE DATE_SUB(CURDATE(),INTERVAL 7 DAY) <= date_col;
However, the above code is for MYSQL but I have SQL Server installed and I was wondering if anyone had a solution for this problem.
Try this:
SELECT something
FROM tbl_name
WHERE date_col >= dateadd(day, -7, getdate());
If you want to be sure the time component is removed (as suggested by CURDATE()):
SELECT something
FROM tbl_name
WHERE date_col >= cast(dateadd(day, -7, getdate()) as date);
EDIT:
The answer to the question in your comment is:
SELECT something
FROM tbl_name
WHERE date_col >= cast(dateadd(day, -7, getdate()) as date) and
date_col < cast(dateadd(day, 1, getdate()) as date);
Note the second condition is <, not <=. If date_col has no time component, then:
WHERE date_col >= cast(dateadd(day, -7, getdate()) as date) and
date_col <= cast(getdate() as date)
also works.

I'm trying to design a view and apply several conditions on my timestamp (datetime): last date and last date minus 7 days.
This works fine for the last date:
SELECT *
FROM table
WHERE timestamp = (SELECT MAX(timestamp) FROM table)
I couldn't figure out the way to add minus 7 days so far.
I tried, for instance
SELECT *
FROM table
WHERE (timestamp = (SELECT MAX(timestamp) FROM table)) OR (timestamp = (SELECT DATEADD(DAY, -7, MAX(timestamp)) FROM table)
and some other variations, including GETDATE() instead of MAX, however, I'm getting the execution timeout messages.
Please let me know what logic should I follow in this case.
Data looks like this, but there's more of it :)
So I want to get data only for rows with 29/11/2019 and 22/11/2019. I have an additional requirement for filtering for factors, but it's a simple one.
If you care about dates, then perhaps you want:
select t.*
from t cross join
(select max(timestamp) as max_timestamp from t) tt
where (t.timestamp >= convert(date, max_timestamp) and
t.timestamp < dateadd(day, 1, convert(date, max_timestamp))
) or
(t.timestamp >= dateadd(day, -7, convert(date, max_timestamp)) and
t.timestamp < dateadd(day, -6, convert(date, max_timestamp))
);
So I ended up with the next code:
SELECT *
FROM table
WHERE (timestamp >= CAST(DATEADD(DAY, - 1, GETDATE()) AS datetime)) AND (timestamp < CAST(GETDATE() AS DATETIME)) OR
(timestamp >= CAST(DATEADD(DAY, - 8, GETDATE()) AS datetime)) AND (timestamp < CAST(DATEADD(day, - 7, GETDATE()) AS DATETIME)) AND (Factor1 = 'Criteria1' OR
Factor2 = 'Criteria2')
Not sure if it's the best or the most elegant solution, but it works for me.
I know there are similar answers to this, but none of them have worked for me. I have a query with a date field in it. I want to filter the results for the next 7 days. It works if I specify the dates i.e date between '2019-07-18' AND '2019-07-25' but I need it to be more generic.
Thanks in advance!
Here are a few things I've tried:
CAST( datefield AS DATE ) > DATEADD( DAY, +7, CAST( GETDATE() AS DATE ))
WHERE GETDATE()+7
AND DATEADD(dd, -7, datefield) <= CAST(datefield AS DATETIME)
You can use logic like this:
where datefield >= dateadd(day, 1, cast(getdate() as date)) and
datefield < dateadd(day, 8, cast(getdate() as date))
This assumes you are using SQL Server (based on your syntax) and that you don't want today's data ("next 7 days").
You didnt specify what SQL you are using so this might not be fine for you.
WHERE datefield BETWEEN SYSDATE AND SYSDATE + 7
datefield between today and next 7 days
WHERE
CAST(datefield AS DATE) <= DATEADD(DAY, 7, CAST(GETDATE() AS DATE ))
AND CAST(datefield AS DATE) >= CAST(GETDATE() AS DATE )
I have table HD_Case_Master with a column cm_date_created.
The example value is 2011-05-13 10:07:36.000.
I manage to get the current year but how to get record for all day and month.
SQL statement:
SELECT
cm_create_date
FROM
HD_Case_Master
WHERE
YEAR(cm_create_date) = YEAR(GETDATE()) AND ???
If you want the current date:
SELECT cm_create_date
FROM HD_Case_Master
WHERE cm_create_date >= CAST(GETDATE() as date) AND
cm_create_date < CAST(DATEADD(day, 1, GETDATE()) as date)
If you want to check if cm_date_created is equal to the current date, ignoring the time component, you just need to CAST both dates to DATE:
SELECT *
FROM HD_Case_Master
WHERE
CAST(cm_create_date AS DATE) = CAST(GETDATE() AS DATE)
Alternatively, you can use >= and < to check if cm_date_created falls within the current date:
SELECT *
FROM HD_Case_Master
WHERE
cm_create_date >= CAST(GETDATE() AS DATE)
AND cm_create_date < CAST(DATEADD(DAY, 1, GETDATE()) AS DATE)
You can use DATEPART function of tsql.
... Where DATEPART(day, cm_create_date) = DATEPART(day, getdate()) AND DATEPART(month, cm_create_date) = DATEPART(month, getdate())
You were really close! To add just the month (but ignoring the year), just use this:
SELECT
cm_create_date
FROM
HD_Case_Master
WHERE
YEAR(cm_create_date) = YEAR(GETDATE())
AND MONTH(cm_create_date) = MONTH(GETDATE())
Is there a way to use the Now() function in SQL to select values with today's date?
I was under the impression Now() would contain the time as well as date, but today's date would have the time set to 00:00:00 and therefore this would never match?
OK, lets do this properly. Select dates matching today, using indexes if available, with all the different date/time types present.
The principle here is the same in each case. We grab rows where the date column is on or after the most recent midnight (today's date with time 00:00:00), and before the next midnight (tomorrow's date with time 00:00:00, but excluding anything with that exact value).
For pure date types, we can do a simple comparison with today's date.
To keep things nice and fast, we're explicitly avoiding doing any manipulation on the dates stored in the DB (the LHS of the where clause in all the examples below). This would potentially trigger a full table scan as the date would have to be computed for every comparison. (This behaviour appears to vary by DBMS, YMMV).

There is no native Now() function in SQL Server so you should use:
select GETDATE() --2012-05-01 10:14:13.403
you can get day, month and year separately by doing:
select DAY(getdate()) --1
select month(getdate()) --5
select year(getdate()) --2012
if you are on sql server 2008, there is the DATE date time which has only the date part, not the time:
select cast (GETDATE() as DATE) --2012-05-01
Not sure what your asking!
However
SELECT GETDATE()
Will get you the current date and time
SELECT DATEADD(dd, 0, DATEDIFF(dd, 0, GETDATE()))
Will get you just the date with time set to 00:00:00
Just zero off the time element of the date. e.g.
SELECT DATEADD(dd, DATEDIFF(dd, 0, getdate()), 0)
I've used GetDate as that's an MSSQL function, as you've tagged, but Now() is probably MySQL or you're using the ODBC function call, still should work if you just replace one with the other.
Not sure exactly what you're trying to do, but it sounds like GETDATE() is what you're after. GETDATE() returns a datetime, but if you're not interested in the time component then you can cast to a date.
SELECT GETDATE()
SELECT CAST(GETDATE() AS DATE)
Building on the previous answers, please note an important point, you also need to manipulate your table column to ensure it does not contain the time fragment of the datetime datatype.
Below is a small sample script demonstrating the above:
select getdate()
--2012-05-01 12:06:51.413
select cast(getdate() as date)
--2012-05-01
--we're using sysobjects for the example
create table test (id int)
select * from sysobjects where cast(crdate as date) = cast(getdate() as date)
--resultset contains only objects created today
drop table test
I hope this helps.
EDIT:
Following #dwurf comment (thanks) about the effect the above example may have on performance, I would like to suggest the following instead.
We create a date range between today at midnight (start of day) and the last millisecond of the day (SQL server count up to .997, that's why I'm reducing 3 milliseconds). In this manner we avoid manipulating the left side and avoid the performance impact.
select getdate()
--2012-05-01 12:06:51.413
select dateadd(millisecond, -3, cast(cast(getdate()+1 as date) as datetime))
--2012-05-01 23:59:59.997
select cast(getdate() as date)
--2012-05-01
create table test (id int)
select * from sysobjects where crdate between cast(getdate() as date) and dateadd(millisecond, -3, cast(cast(getdate()+1 as date) as datetime))
--resultset contains only objects created today
drop table test
If you have a table with just a stored date (no time) and want to get those by "now", then you can do this:
SELECT * FROM tbl WHERE DATEDIFF(d, yourdate, GETDATE())=0
This results in rows which day difference is 0 (so today).
For me the query that is working, if I want to compare with DrawDate for example is:
CAST(DrawDate AS DATE) = CAST (GETDATE() as DATE)
This is comparing results with today's date.
or the whole query:
SELECT TOP (1000) *
FROM test
where DrawName != 'NULL' and CAST(DrawDate AS DATE) = CAST (GETDATE() as DATE)
order by id desc
You can try this sql code;
SELECT [column_1], [column_1], ...
FROM (your_table)
where date_format(record_date, '%e%c%Y') = date_format(now(), '%e%c%Y')
You can try:
WHERE created_date BETWEEN CURRENT_TIMESTAMP-180 AND CURRENT_TIMESTAMP
This worked for me:
SELECT * FROM table where date(column_date) = curdate()
I am looking for a good SQL Statement to select all rows from the previous day from one table. The table holds one datetime column. I am using SQL Server 2005.
get today no time:
SELECT dateadd(day,datediff(day,0,GETDATE()),0)
get yestersday no time:
SELECT dateadd(day,datediff(day,1,GETDATE()),0)
query for all of rows from only yesterday:
select
*
from yourTable
WHERE YourDate >= dateadd(day,datediff(day,1,GETDATE()),0)
AND YourDate < dateadd(day,datediff(day,0,GETDATE()),0)
To get the "today" value in SQL:
convert(date, GETDATE())
To get "yesterday":
DATEADD(day, -1, convert(date, GETDATE()))
To get "today minus X days": change the -1 into -X.
So for all yesterday's rows, you get:
select * from tablename
where date >= DATEADD(day, -1, convert(date, GETDATE()))
and date < convert(date, GETDATE())
It's seems the obvious answer was missing. To get all data from a table (Ttable) where the column (DatetimeColumn) is a datetime with a timestamp the following query can be used:
SELECT * FROM Ttable
WHERE DATEDIFF(day,Ttable.DatetimeColumn ,GETDATE()) = 1 -- yesterday
This can easily be changed to today, last month, last year, etc.
SELECT * from table_name where date_field = DATE_SUB(CURRENT_DATE(),INTERVAL 1 DAY);
Its a really old thread, but here is my take on it.
Rather than 2 different clauses, one greater than and less than. I use this below syntax for selecting records from A date. If you want a date range then previous answers are the way to go.
SELECT * FROM TABLE_NAME WHERE
DATEDIFF(DAY, DATEADD(DAY, X , CURRENT_TIMESTAMP), <column_name>) = 0
In the above case X will be -1 for yesterday's records
This should do it:
WHERE `date` = CURDATE() - INTERVAL 1 DAY
Can't test it right now, but:
select * from tablename where date >= dateadd(day, datediff(day, 1, getdate()), 0) and date < dateadd(day, datediff(day, 0, getdate()), 0)
In SQL Server do like this:
where cast(columnName as date) = cast(getdate() -1 as date)
You should cast both sides of the expression to date to avoid issues with time formatting.
If you need to control interval in more detail, then you should try something like:
declare #start datetime = cast(getdate() - 1 as date)
declare #end datetime = cast(getdate() - 1 as date)
set #end = dateadd(second, 86399, #end)
Another way to tell it "Yesterday"...
Select * from TABLE
where Day(DateField) = (Day(GetDate())-1)
and Month(DateField) = (Month(GetDate()))
and Year(DateField) = (Year(getdate()))
This conceivably won't work well on January 1, as well as the first day of every month. But on the fly it's effective.
Well, its easier to cast the datetime column to date and than compare.
SELECT * FROM TABLE_NAME WHERE cast(COLUMN_NAME as date) =
dateadd(day,0, convert(date, getdate(), 105))
A simple alternative
Select GETDATE() - 1
Change 1 to go back that many number of days
PS : This gives you timestamp accuracy.
This worked a charm:
SELECT * FROM mytable WHERE date(mydate) = DATE_SUB(CURDATE(), INTERVAL 1 DAY);
subdate(now(),1) will return yesterdays timestamp
The below code will select all rows with yesterday's timestamp
Select * FROM `login` WHERE `dattime` <= subdate(now(),1) AND `dattime` > subdate(now(),2)
