![]() But if we use it with the + operator, then it will be subtracted from the input date/time. What would be the syntax to minus 15 mins from current datetime I am using it in WHERE clause For Example Where DateTime GetDate () -15 min It should get the current DateTime & minus 15 mins from it. If we use a negative value with the - operator, then the specified number of hours will be added to the input date/time. Select DATEADD minutes with query SQL Server 2008 (3 answers) Closed 2 years ago. It’s possible to perform date arithmetic with negative values. The initial date is so in order to get the correct results, we need to subtract corresponding years, months, and minutes. If the hours to be subtracted are in 24 hour increments, we can alternatively use days: SELECT timestamp ' 15:45' - interval '1 day' Now the difference is correct but the date portion contains the date where SQL Server starts to calculate date values. We can alternatively subtract the equivalent number in minutes: SELECT time '15:45' - interval '120 minutes' Code language: SQL (Structured Query Language) (sql) So the result should be 1416 hours, however, as we mentioned earlier, the result of the TIMEDIFF function is a TIME value which ranges from -838:59:59 to 838:59:59. We can also add a date and time value together, and subtract hours from that: SELECT date '' + time '03:00' - interval '2 hours' We can even subtract hours from a date value: SELECT date '' - interval '8 hours' We can also subtract hours from an interval: SELECT interval '5 hours' - interval '2 hours' So to subtract one or more hours, we can use hour or hours: SELECT time '07:00' - interval '1 hour' Īnd in plural form: SELECT time '07:00' - interval '2 hours' Īnd here it is with a timestamp value: SELECT timestamp ' 09:00' - interval '30 hours' ![]() The following table lists examples of expressions that use the DateAdd function to add date and time values. We can specify intervals when performing arithmetic against dates and times. Add to or subtract from date and time values Add to or subtract from date and time values Access for Microsoft 365 Access 2021 Access 2019 Access 2016 Access 2013 More. We can also subtract hours from a date value or a date and time combination.
