I have a
start_date
and
end_date
. I want to get the list of dates in between these two dates. Can anyone help me pointing the mistake in my query.
select Date,TotalAllowance
from Calculation
where EmployeeId=1
and Date between 2011/02/25 and 2011/02/27
Here Date is a datetime variable.
you should put those two dates between single quotes like..
select Date, TotalAllowance from Calculation where EmployeeId = 1
and Date between '2011/02/25' and '2011/02/27'
or can use
select Date, TotalAllowance from Calculation where EmployeeId = 1
and Date >= '2011/02/25' and Date <= '2011/02/27'
keep in mind that the first date is inclusive, but the second is exclusive, as it effectively is '2011/02/27 00:00:00'

Since a datetime without a specified time segment will have a value of date 00:00:00.000, if you want to be sure you get all the dates in your range, you must either supply the time for your ending date or increase your ending date and use <.
select Date,TotalAllowance from Calculation where EmployeeId=1
and Date between '2011/02/25' and '2011/02/27 23:59:59.999'
select Date,TotalAllowance from Calculation where EmployeeId=1
and Date >= '2011/02/25' and Date < '2011/02/28'
select Date,TotalAllowance from Calculation where EmployeeId=1
and Date >= '2011/02/25' and Date <= '2011/02/27 23:59:59.999'
DO NOT use the following, as it could return some records from 2011/02/28 if their times are 00:00:00.000.
select Date,TotalAllowance from Calculation where EmployeeId=1
and Date between '2011/02/25' and '2011/02/28'

select Date,TotalAllowance from Calculation where EmployeeId=1
and [Date] between '2011/02/25' and '2011/02/27'
The date values need to be typed as strings.
To ensure future-proofing your query for SQL Server 2008 and higher, Date should be escaped because it's a reserved word in later versions.
Bear in mind that the dates without times take midnight as their defaults, so you may not have the correct value there.

select * from table_name where col_Date between '2011/02/25'
AND DATEADD(s,-1,DATEADD(d,1,'2011/02/27'))
Here, first add a day to the current endDate, it will be 2011-02-28 00:00:00, then you subtract one second to make the end date 2011-02-27 23:59:59. By doing this, you can get all the dates between the given intervals.
output:
2011/02/25
2011/02/26
2011/02/27
This query stands good for fetching the values between current date and its next 3 dates
SELECT * FROM tableName WHERE columName
BETWEEN CURDATE() AND DATE_ADD(CURDATE(), INTERVAL 3 DAY)
This will eventually add extra 3 days of buffer to the current date.
This is very old, but given a lot of experiences I have had with dates, you might want to consider this: People use different regional settings, as such, some people (and some databases/computers, depending on regional settings) may read this date 11/12/2016 as 11th Dec 2016 or Nov 12, 2016. Even more, 16/11/12 supplied to MySQL database will be internally converted to 12 Nov 2016, while Access database running on a UK regional setting computer will interpret and store it as 16th Nov 2012.
Therefore, I made it my policy to be explicit whenever I am going to interact with dates and databases. So I always supply my queries and programming codes as follows:
SELECT FirstName FROM Students WHERE DoB >= '11 Dec 2016';
Note also that Access will accept the #, thus:
SELECT FirstName FROM Students WHERE DoB >= #11 Dec 2016#;
but MS SQL server will not, so I always use " ' " as above, which both databases accept.
And when getting that date from a variable in code, I always convert the result to string as follows:
"SELECT FirstName FROM Students WHERE DoB >= " & myDate.ToString("d MMM yyyy")
I am writing this because I know sometimes some programmers may not be keen enough to detect the inherent conversion. There will be no error for dates < 13, just different results!
As for the question asked, add one day to the last date and make the comparison as follows:
dated >= '11 Nov 2016' AND dated < '15 Nov 2016'

if its date in 24 hours and start in morning and end in the night should add something like :
declare @Approval_date datetime
set @Approval_date =getdate()
Approval_date between @Approval_date +' 00:00:00.000' and @Approval_date +' 23:59:59.999'
SELECT CITY, COUNT(EID) OCCURENCES FROM EMP
WHERE DOB BETWEEN '31-JAN-1900' AND '31-JAN-2900'
GROUP BY CITY
HAVING COUNT(EID) > 2;
This query will find Cities with more than 2 occurrences where their DOB is in a specified time range for employees.

select Date,TotalAllowance from Calculation where EmployeeId=1
and Date >= '2011/02/25' and Date < DATEADD(d, 1, '2011/02/27')
The logic being that >= includes the whole start date and < excludes the end date, so we add one unit to the end date. This can adapted for months, for instance:
select Date, ... from ...
where Date >= $start_month_day_1 and Date < DATEADD(m, 1, $end_month_day_1)
best query for the select date between current date and back three days:
select Date,TotalAllowance from Calculation where EmployeeId=1 and Date BETWEEN
DATE_SUB(CURDATE(), INTERVAL 3 DAY) AND CURDATE()
best query for the select date between current date and next three days:
select Date,TotalAllowance from Calculation where EmployeeId=1 and Date BETWEEN
CURDATE() AND DATE_ADD(CURDATE(), INTERVAL 3 DAY)
select * from tblUser Where
convert(varchar(10),CreatedDate,111) between '2015/04/01' and '2016/04/01' //--**Working**
select * from tblUser Where
(CAST(CreatedDate AS DATETIME) between CAST('2015/04/01' AS DATETIME) And CAST('2016/4/30'AS DATETIME)) //--**Working**
select * from tblUser Where
(YEAR(CreatedDate) between YEAR('2015/04/01') And YEAR('2016/4/30'))
//--**Working**
AND below is not working:
select * from tblUser Where
Convert(Varchar(10),CreatedDate,111) >= Convert(Varchar(10),'01-01-2015',111) and Convert(Varchar(10),CreatedDate,111) <= Convert(Varchar(10),'31-12-2015',111) //--**Not Working**
select * from tblUser Where
(Convert(Varchar(10),CreatedDate,111) between Convert(Varchar(10),'01-01-2015',111) And Convert(Varchar(10),'31-12-2015',111)) //--**Not Working**
I like to use the syntax 1 MonthName 2015 for dates ex:
WHERE aa.AuditDate>='1 September 2015'
AND aa.AuditDate<='30 September 2015'
for dates

In your query, the date values in the between clause are not enclosed in single quotes, which can cause an error. Additionally, when specifying date literals, it's recommended to use the ISO 8601 format 'YYYY-MM-DD' for clarity and to avoid any ambiguity.
Here's the corrected query:
SELECT Date, TotalAllowance
FROM Calculation
WHERE EmployeeId = 1
AND Date BETWEEN '2011-02-25' AND '2011-02-27';
In this query, the date values '2011-02-25' and '2011-02-27' are enclosed in single quotes to indicate that they are string literals representing dates. By using the ISO 8601 format, you ensure that the dates are interpreted correctly.
Utilizing dbForge Studio's SQL editor, you can execute your queries and efficiently accomplish a wide range of database management tasks.
we can use between to show two dates data but this will search the whole data and compare so it will make our process slow for huge data, so i suggest everyone to use datediff:
qry = "SELECT * FROM [calender] WHERE datediff(day,'" & dt & "',[date])>=0 and datediff(day,'" & dt2 & "',[date])<=0 "
here calender is the Table, dt as the starting date variable and dt2 is the finishing date variable.
There are a lot of bad answers and habits in this thread, when it comes to selecting based on a date range where the records might have non-zero time values - including the second highest answer at time of writing.
Never use code like this: Date between '2011/02/25' and '2011/02/27 23:59:59.999'
Or this: Date >= '2011/02/25' and Date <= '2011/02/27 23:59:59.999'
To see why, try it yourself:
DECLARE @DatetimeValues TABLE
(MyDatetime datetime);
INSERT INTO @DatetimeValues VALUES
('2011-02-27T23:59:59.997')
,('2011-02-28T00:00:00');
SELECT MyDatetime
FROM @DatetimeValues
WHERE MyDatetime BETWEEN '2020-01-01T00:00:00' AND '2020-01-01T23:59:59.999';
SELECT MyDatetime
FROM @DatetimeValues
WHERE MyDatetime >= '2011-02-25T00:00:00' AND MyDatetime <= '2011-02-27T23:59:59.999';
In both cases, you'll get both rows back. Assuming the date values you're looking at are in the old datetime type, a date literal with a millisecond value of 999 used in a comparison with those dates will be rounded to millisecond 000 of the next second, as datetime isn't precise to the nearest millisecond. You can have 997 or 000, but nothing in between.
You could use the millisecond value of 997, and that would work - assuming you only ever need to work with datetime values, and not datetime2 values, as these can be far more precise. In that scenario, you would then miss records with a time value 23:59:59.99872, for example. The code originally suggested would also miss records with a time value of 23:59:59.9995, for example.
Far better is the other solution offered in the same answer - Date >= '2011/02/25' and Date < '2011/02/28'. Here, it doesn't matter whether you're looking at datetime or datetime2 columns, this will work regardless.
The other key point I'd like to raise is date and time literals. '2011/02/25' is not a good idea - depending on the settings of the system you're working in this could throw an error, as there's no 25th month. Use a literal format that works for all locality and language settings, e.g. '2011-02-25T00:00:00'.

make sure to include the last day (ending at 24)
select Date, TotalAllowance
from Calculation
where EmployeeId=1
and "2011/02/25" <= Date and Date <= "2011/02/27"
If Date is a DateTime.
I tend to do range checks in this way as it clearly shows lower and upper boundaries. Keep in mind that date formatting varies wildly in different cultures. So you might want to make sure it is interpreted as a date. Use DATE_FORMAT( Date, 'Y/m/d').
(hint: use STR_TO_DATE and DATE_FORMAT to switch paradigms.)
