TIME_FROM_PARTS

Creates a time from individual numeric components.

Aliases:

TIMEFROMPARTS

Syntax

TIME_FROM_PARTS( <hour>, <minute>, <second> [, <nanoseconds>] )

Arguments

Required:

hour

An integer expression to use as an hour for building a time, usually in the 0-23 range.

minute

An integer expression to use as a minute for building a time, usually in the 0-59 range.

second

An integer expression to use as a second for building a time, usually in the 0-59 range.

Optional:

nanoseconds

A 9-digit integer expression to use as a nanosecond for building a time.

Usage notes

TIME_FROM_PARTS is typically used to handle values in “normal” ranges (e.g. hours 0-23, minutes 0-59), but it also handles values from outside these ranges. This allows, for example, choosing the N-th minute in a day, which can be used to simplify some computations.

Examples

ALTER SESSION SET TIME_OUTPUT_FORMAT='HH24:MI:SS.FF9';

Components in normal ranges:

select time_from_parts(12, 34, 56, 987654321);

----------------------------------------+
 TIME_FROM_PARTS(12, 34, 56, 987654321) |
----------------------------------------+
 12:34:56.987654321                     |
----------------------------------------+

Components outside normal ranges:

  • 100th minute (from midnight)

  • 12345 seconds (from noon)

    select time_from_parts(0, 100, 0), time_from_parts(12, 0, 12345);

----------------------------+-------------------------------+
 TIME_FROM_PARTS(0, 100, 0) | TIME_FROM_PARTS(12, 0, 12345) |
----------------------------+-------------------------------+
 01:40:00.000000000         | 15:25:45.000000000            |
