Question

I am trying to extract an amount of years from a specific date for this the correct syntax is

<date> - interval '5 years';

But I dont want to extract a specific amount of years but a variable, which user will provide as a parameter. I have tried the following the variable name is years :

date+interval '% years',years;

I am getting an error and it doesn’t let me do it that way. What would be the right way to do it.

Answer 1

I believe you should be able to write:

specific_date + (number_of_years || ' years')::INTERVAL

(Disclaimer: not tested, and it’s been more than a year since I last did this sort of thing.)
