In order to add seconds to datetime(timestamp) in PostgreSQL we will be using the make_interval() function and another approach by using the + operator and Interval. datatype. datatype. Here are examples of the approach. Also, we will look at how to Add seconds to datetime(timestamp) column in PostgreSQL table.
Add seconds to datetime in PostgreSQL using INTERVAL data type:
We will be Using the INTERVAL data type to add seconds to datetime in PostgreSQL. When we add seconds to datetime(timestamp) using INTERVAL datatype the output will be in datetime(timestamp) format. In below example, we have added 30 seconds to datetime using Interval data type.
Example 1:
SELECT '2024-02-24 12:00:00'::timestamp + INTERVAL '30 seconds' AS new_datetime
Output:
Add Seconds to datetime in PostgreSQL using make_interval() function:
We will be Using the make_interval() function to add seconds to datetime in PostgreSQL. When we add seconds to datetime using the make_interval() function, the output will be in datetime(timestamp) format. In below example, we have added 30 Seconds to timestamp
Example 1:
SELECT '2024-02-24 12:00:00'::timestamp + make_interval(secs => 30) as new_datetime
Output:
Add seconds to datetime(timestamp) column in PostgreSQL table using Interval datatype:
We will be using below student_detail1 table for our example to depict on how to add seconds to datetime(timestamp) column in postgresql table.
student_detail1:
We have added 30 seconds to datetime column using INTERVAL datatype in postgresql and new column named new_date is being created as shown below.
select *, birthdaytime::timestamp + INTERVAL '30 SECONDS' as new_date from student_detail1
Output:
Add Seconds to datetime column in PostgreSQL table using make_interval() function:
We will have added 30 seconds to datetime column using make_interval() function in postgresql and new column named new_date is being created as shown below.
select *,birthdaytime::timestamp + make_interval(secs => 30) as new_date from student_detail1
Output:
