In order to add Seconds to current datetime(timestamp) in PostgreSQL we will be using the two approaches one by using the make_interval() and other by Interval. datatype. Here are examples of both the approaches. Also, we will look at how to Add Seconds to current datetime(timestamp) column in PostgreSQL table.
Add Seconds to current timestamp in PostgreSQL using INTERVAL data type:
We will be Using the INTERVAL data type to add Seconds to current datetime in PostgreSQL. When we add Seconds to current datetime(timestamp) using INTERVAL datatype the output will be in datetime(timestamp) format. In below example, we have added 30 second to current datetime using Interval data type.
Example 1 using CURRENT_TIMESTAMP:
SELECT CURRENT_TIMESTAMP::timestamp + INTERVAL '30 seconds' AS new_datetime
Output:
Example 2 using NOW():
SELECT NOW()::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 current datetime(timestamp) format. In below example, we have added 30 second to timestamp
Example 1 using CURRENT_TIMESTAMP:
SELECT CURRENT_TIMESTAMP::timestamp + make_interval(secs => 30) as new_datetime
Output:
Example 2 using NOW():
SELECT NOW()::timestamp + make_interval(secs => 30) as new_datetime
Output:
Add Seconds to current datetime(timestamp) column in PostgreSQL table using Interval datatype:
We will be using below fruits table for our example to depict on how to add Seconds to current datetime(timestamp) column in PostgreSQL table.
fruits:
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.
Example 1 : using NOW() function
select *,NOW()::timestamp as current_dt, NOW()::timestamp + INTERVAL '30 secondS' as new_date from fruits
OR
Example 2 : using CURRENT_TIMESTAMP
select *,CURRENT_TIMESTAMP::timestamp as current_dt, CURRENT_TIMESTAMP::timestamp + INTERVAL '30 secondS' as new_date from fruits
Output:
Add Seconds to datetime column in PostgreSQL table using make_interval() function:
We 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.
Example 1 : using NOW() function
select *,NOW()::timestamp as current_dt, NOW()::timestamp + make_interval(secs => 30) as new_date from fruits
OR
Example 2 : using CURRENT_TIMESTAMP
select *,CURRENT_TIMESTAMP::timestamp as current_dt, CURRENT_TIMESTAMP::timestamp + make_interval(secs => 30) as new_date from fruits
Output:
