First day of current year

Question

I have the below query in a postgresql database

SELECT * 
FROM accounts 
where insertdate BETWEEN '2012-01-01' AND CURRENT_TIMESTAMP

So how can I replace the '2012-01-01' asking for the first day of the current year

There is one more issue. When I m having a new record in the account table the same moment is running the above select so it doesnt bring me the record I have just made.Is it reasonable? What is the best way to overtake it?

Answer 1

You're looking for date_trunc(), which can truncate a date to a specified precision (e.g. year, month, day):

SELECT date_trunc('year', now());

In your query:

SELECT * FROM accounts where insertdate BETWEEN 
date_trunc('year', now()) AND CURRENT_TIMESTAMP
