1 - Introduction

In this lesson we are going to learn how to use the (Access report with filter - Child Class) template.

2 - Implementation Steps

Create new file using the template (Access report with filter – child class)

The cDate() function used to convert text column to data column

Since dateofbirth is a date column not text, we don’t need to use cDate() with dateofbirth (self:dateColumn)
