A few tips and tricks to make your coding life a tiny bit better.

Calculated age field (given date of birth)

Purpose of this recipe

You have a table personal info of interest (for example, employees in a company, students in a school, patients in a hospital… etc). Among the info stored is the date of birth. You’d like to use this to calculate the current age of the person.

This can be achieved by using a calculated field, and entering an SQL query similar to the one below.

Files to edit

This SQL query below can be added in AppGini: Add an age field of type Integer to your table, and in the Calculated field tab, add the following SQL query:

SELECT FLOOR(DATEDIFF(NOW(), `BirthDate`) / 365)

In the above query, replace BirthDate with the actual name of the birth date field. Whenever you visit the table in AppGini, the age field would be automatically updated to reflect the current age of each person.
