Introduction to the PostgreSQL MAKE_TIME() function

TheMAKE_TIME() function allows you to create atime value from hour, minute, and second values.

Here’s the syntax of theMAKE_TIME() function:

MAKE_TIME (hour int, minint, secdouble precision ) →time

In this syntax:

• hour: The hour part of the time. The valid range for the hour is from 0 to 23. 0 represents midnight (12:00 AM) and 24 represents noon.
• min: The minute part of the time. The valid range for the second is from 0 to 59.
• sec: The second within a minute. Its valid range is from 0 to59.999999.

TheMAKE_TIME() function returns a time value constructed from the hour, min, and sec.

If you use invalid values for hour, min, and sec, the function will issue an error.

PostgreSQL MAKE_TIME() function examples

Let’s explore some examples of using theMAKE_TIME() function.

1) Basic MAKE_TIME() function examples

The following example uses theMAKE_TIME() function to construct a time22:30:45 from hour, minute, and second:

SELECT MAKE_TIME(22,30,45);

Output:

make_time----------- 22:30:45(1 row)

The following example attempts to use invalid values for hour, minute, and second to construct a time and results in an error:

SELECT MAKE_TIME(25,30,45);

Error:

ERROR:time fieldvalue out ofrange:25:30:45

2) Using the MAKE_TIME() function with string arguments

Even though the type of hour and minute parameters are integers and seconds are double precision, you can pass string arguments to theMAKE_TIME() function.

Behind the scenes, the function will implicitly convert these string arguments to the proper types, as long as the results of the conversions are in the valid range.

SELECT MAKE_TIME('8','30','59.999999');

Output:

make_time----------------- 08:30:59.999999(1 row)

Summary

• Use theMAKE_TIME() function to create a time value from hour, minute, and second values.
