How can I use the “date” keyword in apex for allowing users to get the feature of date range?

54    Asked by DelbertRauch in Salesforce , Asked on Feb 20, 2024

 I am currently engaged in a particular task that is related about developing a Salesforce application for management of various events. Every event has a start date and also an end date. In this management task, I need to execute a feature that can allow users to filter events based on a specific range of data. How can I use the “date” keyword in Apex for this particular objective?

 In the context of Salesforce, you can use the keyword “date” in apex to allow users to get the features of date range so that they can search for the events based on the specific date range. Here is how you can do it:-

Public class EventManager {
    Public static List getEventsByDateRange(Date startDate, Date endDate) {
        // Use SOQL query to retrieve events within the specified date range
        String query = ‘SELECT Id, Name, Start_Date__c, End_Date__c FROM Event__c ‘ +
                       ‘WHERE Start_Date__c >= tartDate AND End_Date__c <= :endDate’;
        Return Database.query(query);
    }
}

You would call this above method passing the required start and also end date to retrieve events within a specific date range. Here is an example given:-

Date startDate = Date.newInstance(2024, 2, 1);
Date endDate = Date.newInstance(2024, 2, 15);
List events = EventManager.getEventsByDateRange(startDate, endDate);
Thus would retrieve the event that happened between date range of February 1, 2024 and February 15, 2024.
