Tutorials, references, and examples are constantly reviewed to avoid errors, but we cannot warrant full correctness of all content. Okay. This example finds the difference in days between the two dates.

'2011/08/25') AS DateDiff; SELECT DATEDIFF(hour, '2017/08/25 07:00', '2017/08/25 12:45') AS DateDiff; W3Schools is optimized for learning and training. What does this mean? Then you just need to multiply the date difference by 24 (number of hours per day) and then by 60 (number of minutes per hour) to calculate the interval in minutes: SELECT (CAST('2011-10-08 01:23:00' AS date) - CAST('2011-10-07 23:43:00' AS date))*24*60 SELECT DATEDIFF('2011-10-07T23:43:00', '2011-10-08T01:23:00'); This example finds the difference in days between the two dates.

Let’s take a look at some examples of the SQL DATEDIFF function. The two dates to calculate the difference between, SQL Server (starting with 2008), Azure SQL Database, Azure SQL Data January=1, February=2, etc.) One thing to keep in mind is that the DATEDIFF function is used. Now let’s take the interval from Saturday 29-10-2005 to Sunday 30-10-2005: SELECT DATEDIFF(wk, '20051029', '20051030'); The result will be 1, that is, one week. For example: SELECT DATEDIFF(year, '25.12.2015', '25.12.2017'); Why use it? But it’s not a bug. Quick Example: -- The difference is days between today and yesterday SELECT DATEDIFF(dd, GETDATE() - 1, GETDATE()); -- Returns: 1 -- The number of seconds in 24 hours SELECT DATEDIFF(ss, GETDATE() - 1, GETDATE()); -- Returns: 86400 The answer is by using DateDiff in SQL Server. SELECT DATEDIFF(wk, '20051023', '20051029'); Common sense suggests that this is a full week, but the above query gives 0. For example, if you’re trying to find out how many milliseconds are in a 1000 years, you’ll get an error. Result (assuming we have data populated in this table): The DATEDIFF function can be used in SQL Server to find the difference between two dates, using a range of units from years all the way down to fractions of a second. datepart: This is the units that the DATEDIFF function calculates the difference between the two dates. You can use functions that return dates, such as MIN and MAX, inside DATEPART. SELECT DATEDIFF(year, '2014-03-12 02:10:16', '2019-12-14 08:09:55'); … Note that in this case, we could’ve used DATEDIFF(), as the result is not too big for an integer. Here’s an example of returning the number of hours, minutes, and seconds between the date/time values: And here’s an example of getting the number of milliseconds, microseconds, and nanoseconds between two date/time values: If you try to do something extreme, like, return the number of nanoseconds in 100 years, you’ll get an error. To calculate the difference between two dates in years, months, weeks, etc., you use the DATEDIFF() function: The DATEDIFF() function accepts three arguments: date_part, start_date, and end_date. The basic syntax behind this SQL Datediff function is as shown below. The function subtracts startdate from enddate. This is because DATEDIFF() returns an int value, and there are more nanoseconds in 100 years than the int data type can handle. The function returns the time interval between two time stamps – startdate and enddate. On the other hand, the DATEDIFF_BIG() function returns a signed bigint data type, which means you can use it to return much larger values. interval – time interval for calculating the difference between date1 and date2. The DATEDIFF SQL Server function allows to calculate the difference between two values of date and time in units of a certain element (i.e. ), Return the difference between two date values, in years: The DATEDIFF() function returns the difference between two dates. SELECT DATEDIFF('2011-10-07T23:43:00', '2011-10-08'); We get one day even if the interval between dates is all one second: SELECT DATEDIFF('2011-10-07T23:59:59', '2011-10-08T00:00:00'); The solution to our problem can be obtained using another built-in function – TIMESTAMPDIFF, which is similar to DATEDIFF function in SQL Server: SELECT TIMESTAMPDIFF(minute, '2011-10-07T23:43:00', '2011-10-08T01:23:00'); PostgreSQL has no function like DATEDIFF (SQL Server) or TIMESTAMPDIFF (MySQL).

SQLShell is a cross-platform command-line tool for SQL, similar to psql for PostgreSQL or MySQL command-line tool for MySQL. The number of seconds is too big for an int (but not for a bigint). The way it works is that it returns the count (as a signed big integer value) of the specified datepart boundaries crossed between the specified startdate and enddate. -Result: 115, SELECT DATEDIFF(hour, '25.12.2017 08:00', '25.12.2017 10:45'); -Result: 2, SELECT DATEDIFF(yyyy, '25.12.2015', '25.12.2017'); startdate is the first date and enddate is the end date.

It takes three parameters and they are all required. The following table lists the valid values of date_part: The DATEDIFF() function returns a value of integer indicating the difference between the start_date and end_date, with the unit specified by date_part. And finally, here’s an example with milliseconds, microseconds, and nanoseconds: In this case, we can clearly see the benefit that DATEDIFF_BIG() has over DATEDIFF(). You want confirmation? First, here’s the syntax: DATEDIFF_BIG ( datepart , startdate , enddate ) Where datepart is the part of the date that you want compared. SQL Server vNext, SQL Server 2016, SQL Server 2015, SQL Server 2014, SQL Server 2012, SQL Server 2008 R2, SQL Server 2008, SQL Server 2005. year, month, day), it takes into account only a certain element and higher elements in the time hierarchy – but not lower elements. Required. This function returns a signed bigint data type, which allows you to return much larger values than DATEDIFF() can. FROM pass_in_trip Count the number of minutes between two dates – ‘2011-10-07 23:43:00’ and ‘2011-10-08 01:23:00’. We can calculate the interval in minutes, taking into account that the difference in dates (values like date) in Oracle gives the result the number of days (day). The fact is that the DATEDIFF function actually considers a week not the number of days, but the number of transitions from Saturday to Sunday. In the MSDN documentation and other sites it mentions the concept of “datepart boundaries”. this Workaround for DATEDIFF() Ignoring SET DATEFIRST in SQL Server. Example. First, here’s the syntax: DATEDIFF_BIG ( datepart , startdate , enddate ) Where datepart is the part of the date that you want compared. First, here’s the syntax: Where datepart is the part of the date that you want compared. One practical example of using the DATEDIFF function in SQL Server is in a WHERE clause by selecting all employees in the AdventureWorks2008R2 database whose date of hire was in March 2003. SELECT DATEDIFF(dd, '20051029 23:59:00', '20051030 00:01:00'); SELECT DATEDIFF(dd, '20051029 00:00:00', '20051029 23:59:59'); The challenge. -Result: 2, SELECT DATEDIFF(yy, '25.12.2015', '25.12.2017');
