How to compare timestamps interval on Oracle SqlDeveloper?

Question

I have two columns of type timestamp(6) in my table.

I want to find all the rows in the table where the time between these two timestamps is greater than 300 days. How do I write the WHERE clause of my SQL statement?

I want to write something like this:

SELECT *
FROM   TABLE
WHERE  timestamp1 - timestamp2 > 300

Answer 1

这听起来像你想要的

WHERE (column1 - column2) > numtodsinterval( 300, 'day' )
