Here, we create a function namedCalculateAge. Furthermore, the function utilizes PostgreSQL’s built-inage()function to determine the difference between two dates. Since only one argument is provided,age()calculates the difference between the given date and the current date. Consequently, theCalcula...
In Example 8, the distinction between the round() and trunc() functions is illustrated. While the round() function adds 1 to the number, the trunc() function simply removes the decimal part and rounds the number down to the nearest integer. To demonstrate this difference, we will apply bot...

In both cases, a few hundred individuals work on the main server code. The main difference in the development is that PostgreSQL’s new functionality is open for observation (if you are on the right mailing list) while Oracle often provides little or no notice of something new. ...
