Vertica Quick Tip: How old am I?

This blog post was authored by Jim Knicely. The AGE_IN_YEARS function returns the difference in years between two dates, expressed as an integer. This function is very useful when I forget how old I am or how old my wife is being that today is her birthday. Example:

dbadmin=> SELECT extract(year from sysdate) "Current Year", age_in_years('04/05/1987') "How young does my wife think she is?";
Current Year | How young does my wife think she is?
--------------+--------------------------------------
2018 |                                   30

July 21, 2023

If a user tries to login using their credentials and the authentication fails, the user cannot login using other authentication methods.

How to set it? As a dbadmin user, create a user resource pool. The pool name can be used to configure the DefaultResourcePoolForUsers option. In...
