- Interval Type 9856
- INTERVAL s represent periods of time that can be added to or subtracted from DATE , TIMESTAMP , TIMESTAMPTZ , or TIME values. Name Description INTERVAL Period of time An INTERVAL can be constructed by providing amounts together with units.

For example, we can generate a...0-01-01' + INTERVAL (i) MONTH FROM range(12) t(i); When INTERVAL s are deconstructed via the datepart function, the months component is additionally split into years and months, and the microseconds component is split into hours, minutes and microseconds....The days component is not split into additional units.
