![]() ![]() But if we use it with the + operator, then it will be subtracted from the input date/time. If we use a negative value with the - operator, then the specified number of minutes will be added to the input date/time. It’s possible to perform date arithmetic with negative values. Postgresql select join by date - Join rows where a timestamp value is. ![]() If the minutes to be subtracted are in 60 minute increments, we can alternatively use hours: SELECT time '15:45' - interval '1 hour' We can use DATEADD() function like below to Subtract days from DateTime in Sql Server. We can alternatively subtract the equivalent number in seconds: SELECT time '15:45' - interval '120 seconds' We can also add a date and time value together, and subtract minutes from that: SELECT date '' + time '01:00' - interval '18 minutes' We can even subtract minutes from a date value: SELECT date '' - interval '12 minutes' We can also subtract minutes from an interval: SELECT interval '5 hours' - interval '90 minutes' So to subtract one or more minutes, we can use minute or minutes: SELECT time '07:00' - interval '1 minute' Īnd in plural form: SELECT time '07:00' - interval '45 minutes' Īnd here it is with a timestamp value: SELECT timestamp ' 09:00' - interval '30 minutes' We can specify intervals when performing arithmetic against dates and times. We can also subtract minutes from a date value or a date and time combination. ![]() In PostgreSQL, we can use the - operator to subtract one or more minutes from a time value.īy “time” value, this could be an actual time value, a timestamp, or an interval. ![]()
