The source can be a date or timestamp value.
MINUTE: It is the minute (0-59) or a number of minutes. SELECT pto.startdate, pto.enddate, SUM (CASE WHEN extract (dow FROM foo) IN (1,2,3,4,5) THEN 1 ELSE 0 END) as theDIFF FROM ( SELECT startdate, (startdate::date + (generateseries (0,enddate::date - startdate::date)'days')::interval) AS foo FROM pto ) foo inner join pto pto on pto.startdate foo.startdate group by pto.startdate, pto.MILLISECONDS: It is the second’s field, including fractional parts,.MILLENNIUM: It is the number of millennium.EPOCH: It is the total number of seconds in the interval.DOY: it is the day of the year that ranges from 1 to 366.DOW: It is the day of the week Sunday (0) to Saturday (6).DECADE: It is the decade that is the year divided by 10.DAY: It is the day of the month (1-31) or the number of days.PostgreSQL will silently disregard any time zone information in a literal that. Where sub-field can be the following values. Sql datediff function using date difference, sql server datediff days. For brevity, these variants are not shown separately. Postgresql difference between two timestamps in yearsĭifference between two timestamps in PostgreSQLīefore beginning, we need to know about the PostgreSQL function named EXTRACT() that retrieves or extracts a sub-field such as a year, month, and day from a date and timestamp value. All the functions and operators described below that take time or timestamp inputs actually come in two variants: one that takes time with time zone or timestamp with time zone, and one that takes time without time zone or timestamp without time zone.Postgresql difference between two timestamps in minutes.In SQL Server: Like we do in SQL Server its much easier.
