In this article, we have seen how to add minutes, hours, months to date/time values in PostgreSQL.Working with dates & times is one of the biggest challenges in Power Apps. Psql> select * from sales where order_date > now() - interval '1 month' Psql> select * from sales where order_date > now() - interval '1 day' Psql> select * from sales where order_date > now() - interval '1 hour' Psql> select * from sales where order_date > now() - interval '1 minute' Here is an example to select rows within last 1 minute, 1 hour, 1 day, 1 month. You can also use interval operator inside WHERE clause, to select rows within a certain interval.

Psql> select now() - interval '1 month' from sales Psql> select now() + interval '1 month' from sales # add/subtract 1 month from present date/time value Psql> select now() - interval '1 day' from sales Psql> select now() + interval '1 day' from sales # add/subtract 1 day from present date/time value Psql> select now() - interval '1 hour' from sales Psql> select now() + interval '1 hour' from sales # add/subtract 1 hour from present date/time value Psql> select now() - interval '1 minute' from sales Psql> select now() + interval '1 minute' from sales now() function returns the current datetime in PostgreSQL # add/subtract 1 minute from present date/time value Here are some queries to add/subtract minutes, hours, days, months to current datetime in PostgreSQL. You can also use interval operator with system datetime values, not just columns. Please note, interval operator works with date/time/datetime columns in PostgreSQL. Psql> select order_date - interval '1 month' from sales Psql> select order_date + interval '1 month' from sales # add/subtract 1 month from date/time column You need to use the keyword ‘month’ to add/subtract month from date/time values. Psql> select order_date - interval '1 day' from sales Psql> select order_date + interval '1 day' from sales # add/subtract 1 day from date/time column Similarly, you need to use keyword day in order to add/subtract days from date/time values. Psql> select order_date - interval '1 hour' from sales Psql> select order_date + interval '1 hour' from sales In this case, you need to use keyword ‘hour’ when you specify time interval in PostgreSQL # add/subtract 1 hour from date/time column Similarly, here is the command to add/subtract hours from datetime values in PostgreSQL. psql> select order_date - interval '1 minute' from sales Here is the query to subtract 1 minute from order_date column. After that, add the interval keyword, followed by the amount of days/time that you want to add/subtract. We need to basically add +/- sign after date/time column, depending on whether you want to add or subtract time value. Please note, in the above SQL query, we need to put 1 minute within quotes. psql> select order_date + interval '1 minute' from sales

Here is the query to add 1 minute to order_date column of sales table. Let us say you have table sales(order_id, order_date, amount, product_id) in PostgreSQL. We will use ‘interval’ operator for our article, as it is very easy to remember and use. There are many ways to add minutes, hours, days and months to your date/time value in PostgreSQL.
