The below query returns MINUTE of certain hour of a date.
For example if date value ='2017-07-19 05:50:00.000', it will returns 50.
My issue is I need to get MINUTE in specified date not all the dates that exist in the table.
Query:
SELECT
DATEPART(MINUTE, ClockOut)
FROM
[dbo].[Attendance]
WHERE
DATEPART(HOUR, ClockOut) = '5'
The query I tried to return minutes only in '2017-07-19' and it returns no record.
SELECT
DATEPART(MINUTE, ClockOut)
FROM
[dbo].[Attendance]
WHERE
DATEPART(HOUR, ClockOut) = '5' AND ClockOut = '2017-07-19'
Sample data
Clock Out
2017-07-19 05:50:00.000
2017-07-20 05:51:00.000
2017-07-21 05:52:00.000
I need to return minutes at hour 5 only on this date '2017-07-19'
You are comparing datetime to date that's why it is not returning your desired result.
SELECT DATEPART(MINUTE, ClockOut)
FROM [dbo].[Attendance]
WHERE DATEPART(HOUR, ClockOut) = '5'
AND CAST(ClockOut AS DATE) = '2017-07-19';
If you use ClockOut='2017-07-19' it's like write '2017-07-19 0:00:00'. Try to use DataPart (yyyy, Clockout)=2017 and DataPary (MM, Clockout)=7 and DataPart (dd, Clockout)=19
Your ClockOut columns contains a DateTime (2017-07-19 12:03:42) so it's value is never exact equal to a date (2017-07-19). Use a range instead so the Query Plan can use an potential index on Clockout. Casting to a Date or using DatePart rules this out causing longer execution times if the number of rows is large.
SELECT DATEPART(MINUTE, ClockOut)
FROM [dbo].[Attendance]
WHERE DATEPART(HOUR, ClockOut) = 5
AND ClockOut BETWEEN '2017-07-19'
AND '2017-07-20' -- start of next day

My SQL table looks like this:
IN_Time Day Name
21:00 Monday Adam781;
22:15 Tuesday Adam952;
23:45 Friday Adam253;
...
I want the query to return the name if {current day && current time} matches Day and In_time column.
e.g So if today is Tuesday and time is 22:15(irrespective of date), query should return Adam952
Below is what I tried, but can't figure out how to add Day as well
SELECT Name FROM test_table
WHERE In_Time IN (SELECT CONVERT(VARCHAR(5), GETDATE(), 108)+':00');
Also, please let me know if there is a better way to select current time(in hh:mm).
You can use:
SELECT Name
FROM test_table
WHERE DAY = DATENAME(weekday, GETDATE()) AND
INTIME = CONVERT(TIME, GETDATE())
Note that this answers your question, but the time needs to match exactly. If you just want the hours and minutes to match:
SELECT Name
FROM test_table
WHERE DAY = DATENAME(weekday, GETDATE()) AND
DATEPART(HOUR, INTIME) = DATEPART(HOUR, GETDATE()) AND
DATEPART(MINUTE, INTIME) = DATEPART(MINUTE, GETDATE())
You also need to compare [day] column with today.
SELECT Name
FROM [test_table]
WHERE IN_Time = CONVERT(varchar(8),getdate(),8)
and [day] = datename(weekday,getdate());
I'm trying to SELECT all the rows from a SQL database which are between an hour interval, for every day.
The datetime column is called "Dt" and has the following datetime format: 2019-10-17 16:03:43
I'd like to extract all the rows from this table where the Dt was between 22:00:00 and 02:00:00, for everyday.
SELECT *
FROM MY_TABLE
WHERE "Dt" BETWEEN '*-*- 22:00:00' AND '*-*- 02:00:00';
where * should be any...
Thanks for your support!
EDIT: I forgot to mention: I'm using the integrated SQL interpreter from DB Browser for SQLite
You need to extract the time part of the date and compare that it is within the range. Since midnight is between 22 and 2, you will need to split it to two comparisons, time between 22 and 0 and between 0 and 2.
To see how to extract the time take a look at this question.
With Postgres, assuming dt is defined as timestamp you can do the following:
SELECT *
FROM MY_TABLE
WHERE "Dt" BETWEEN "Dt"::date + time '22:00:00' and ("Dt"::date + 1) + time '02:00:00'
Or if you want to exclude timestamps at precisely 02:00:00
SELECT *
FROM MY_TABLE
WHERE "Dt" >= "Dt"::date + time '22:00:00'
and "Dt" < ("Dt"::date + 1) + time '02:00:00'
select DT_time from (
select cast (substr(to_char(Dt,'dd-mm-yyyy HH:MM:SS'),12,2) as integer ) as DT_time from MY_TABLE )
where DT_time between 2 and 22;
between 22:00:00 and 02:00:00
means:
SELECT *
FROM MY_TABLE
WHERE
substr(Dt, 12) BETWEEN '22:00:00' AND '23:59:59'
OR
substr(Dt, 12) BETWEEN '00:00:00' AND '02:00:00'
This will work ::
SELECT *
FROM MY_TABLE
WHERE DATEPART(HOUR, Dt)>22
AND DATEPART(HOUR, Dt)<2
Update :
SELECT *
FROM MY_TABLE
WHERE Dt Between DATEADD (hour,22,DATEADD(day, DATEDIFF(day, 0, Dt), 0)) AND DATEADD (hour,2,DATEADD(day, DATEDIFF(day, -1, Dt), 0))
SELECT *
FROM MY_TABLE
WHERE DATEPART(HOUR, Dt)>22
OR DATEPART(HOUR, Dt)<2
Above query work for you..
1st one will check only for particular date and consecutive next date along with your time range.
But If you don't care about dates and only looking for time interval in particular hours then 2nd one is for you.
For SQLite :
SELECT *
FROM MY_TABLE
WHERE strftime('%H','Dt')>22
OR strftime('%H','Dt')<2
how to get hour by hour data (no matter what is the date) in sql server, I know it can be achieved with datePart(hour, columnname) but to be specific, I need data for specific intervals including minutes regardless of dates.
Scenario: 'TestTable' contains column - DBTimestamp with data type (DateTime)
I need all Records from 'TestTable' for which 'DBTimestamp' is between 3 Hours 35 Minutes And 4 Hours 30 Minutes regardless of date specified.
You can use this.
SELECT * FROM TestTable WHERE CAST(DBTimestamp AS TIME) BETWEEN '03:35' AND '04:30'
From my understanding you need records that in specific range of time regardless of date part. So I've come up with following solution:
SELECT * FROM (SELECT Id, CAST(Time AS time) [time]
FROM Table) AS Q1
WHERE Q1.time > CAST('03:35:00' AS time)
AND Q1.time < CAST('12:30:00' AS time)
Here is SQL Fiddle:
http://sqlfiddle.com/#!6/21b313/1
Well I guess you could do some variation of the following:
SELECT *
FROM TABLE
WHERE (DATEPART(HOUR, TIMESTAMP) = 3 AND DATEPART(MINUTE, TIMESTAMP) >= 35) OR
(DATEPART(HOUR, TIMESTAMP) = 4 AND DATEPART(MINUTE, TIMESTAMP) <= 30)
am working with MS SQL express and Ignition SCADA by http://www.inductiveautomation.com/
In the SCADA package you are able to create tags from SQL query's. I am trying to use SQL tags to calculate the average packages per minute in a 30min time frame. I was able to do this with two tags and an expression
SELECT MAX(L8Total)
FROM Slicing_tot
WHERE t_stamp BETWEEN DATEADD(minute, -30, GETDATE()) AND GETDATE()
SELECT MIN(L8Total)
FROM Slicing_tot
WHERE t_stamp BETWEEN DATEADD(minute, -30, GETDATE()) AND GETDATE()
What I would like to do from here is store the expressions value and find the max and average for the last 30 days based on time. But I have no idea how to filter 30days of information at a certain time
IE what was the max packages per minute we had at 10:30 from the last 30 days
IE what was the average packages per minute we had at 11:45 form the last 30 days
Please keep in mind that I am new to SQL
SELECT DATEPART(MINUTE, t_stamp)
,MAX(L8Total)
,MIN(L8Total)
FROM Slicing_tot
WHERE ( CONVERT(DATE, t_stamp) >= CONVERT(DATE, GETDATE() - 30)
AND CONVERT(DATE, t_stamp) <= CONVERT(DATE, GETDATE())
)
AND ( CONVERT(TIME, #variable) >= '22:30'
AND CONVERT(TIME, #variable) <= '23:00'
)
GROUP BY DATEPART(MINUTE, t_stamp)
GETDATE()-30 will get you datetime of today minus 30 days ago. Since you are working with datetime field it is best to convert it to date to make sure that you get correct date range. Use of >= and <= is better than between because you is always clear what you doing. Read #Aaron's blog
than for the second part just convert your datetime column to time to limit to specific range during the day.
The following would select between 10 & 11 AM over those 30 days
SELECT MIN(L8Total)
FROM Slicing_tot
WHERE t_stamp BETWEEN DATEADD(dd, -30, GETDATE()) AND GETDATE()
and Datepart(hh,t_stamp) between 10 and 11
or you could compare the time part of the t_stamp to time
SELECT MIN(L8Total)
FROM Slicing_tot
WHERE t_stamp BETWEEN DATEADD(dd, -30, GETDATE()) AND GETDATE()
and convert(time, t_stamp) between '10:30:00.000' and '10:31:00.000'
which would give you the results between 10:30 and 10:31 inclusive of the end points over the last 30 days.
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).

First, using DATE
select * from dates
where dte = CAST(CURRENT_TIMESTAMP AS DATE)
;
Now with DATETIME:
select * from datetimes
where dtm >= CAST(CURRENT_TIMESTAMP AS DATE)
and dtm < DATEADD(DD, 1, CAST(CURRENT_TIMESTAMP AS DATE))
;
Lastly with DATETIME2:
select * from datetimes2
where dtm2 >= CAST(CURRENT_TIMESTAMP AS DATE)
and dtm2 < DATEADD(DD, 1, CAST(CURRENT_TIMESTAMP AS DATE))
;

Backup of SQL Fiddle code
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()
