What Is Trigger In Salesforce ? A trigger in Salesforce is a segment of Apex code that executes before or after inserting or modifying a Salesforce record based on the condition provided. Triggers enable the automation of tasks and the performance of custom actions before and after events in Salesforce, such as data insertions, updates, or deletions. They are essential for carrying out various actions and can be used to validate or modify field values, create or modify related records, perform complex calculations, enforce custom business logic, or integrate with external systems. Triggers are written in Apex, Salesforce's proprietary programming language, and they are used to handle data manipulation language (DML) events. There are two types of triggers: before triggers and after triggers, each serving different purposes in the data manipulation process #salesforce #trigger #trailblazercommunity

What is Break and Continue Statement in Apex and how to declare it ? In Apex programming language, which is used in Salesforce development, the break and continue statements are used within loops to control the flow of execution. 1.Break Statement: The break statement is used to exit a loop prematurely. When the break statement is encountered inside a loop, the loop is terminated, and the program continues with the next statement after the loop. SYNTAX: for (initialization; condition; update) {   // code to be executed   if (some Condition) {     break; // exit the loop prematurely   } } 2.Continue Statement: The continue statement is used to skip the rest of the code inside the loop for the current iteration and move on to the next iteration. SYNTAX: for (initialization; condition; update) {   // code to be executed   if (some Condition) {     continue; // skip the rest of the loop code and move to the next iteration   } } #salesforce #salesforcedeveloper #apex

#DataTypes play a crucial role in memory allocation and data manipulation, making them fundamental in programming languages like Apex They help in predicting the behavior of the code, ensuring a detailed and thorough code execution They also directly reference object-oriented schema, such as field names, and if any references are faulty, the code fails to compile quickly Apex supports a variety of data types, including: #Primitive Types: These include Integer, Double, Long, Date, Datetime, String, ID, Boolean, and Blob. These are the most basic data types and are used to represent simple values like numbers, characters, and booleans #sObject: This is a generic data type that can represent any object, whether it is a standard object or a custom object #Collections: These include Lists, Sets, and Maps. Collections are used to store multiple data. They are useful when you want to work with many records at the same time #Enums: An abstract data type that is used to stores one value of a finite set of specified identifiers #Classes and Interfaces: These are user-defined data types that allow you to create complex data structures In #summary, data types in Apex are used to ensure the correct handling of data, improve code reliability, and enhance the efficiency of memory usage. They are fundamental to the development of robust and scalable applications on the Salesforce platform #Apex #Salesforce #DataTypes #Programming #MemoryManagement #CodeReliability

What is Class in Apex and How to declare it ? In Apex, a class is a blueprint or template for creating objects. It defines a data structure that encapsulates data and behavior related to that data. A class in Apex is similar to classes in other object-oriented programming languages. >A class is a user-defined data type that represents a blueprint for creating objects. Objects are instances of a class, and they contain both data and methods that operate on the data. >Classes support encapsulation, allowing you to hide the internal details of the class and expose only what's necessary. This helps in organizing and structuring your code, making it more modular. >You can use access modifiers like public, private, or protected to control the visibility of class members (variables and methods). By default, class members are private. Class Syntax: [public | private | protected] [virtual | abstract | with sharing | without sharing] class ClassName [extends ParentClass] [implements Interface1, Interface2, ...] {   // Class members (variables and methods) go here   [modifiers] dataType memberName1 [= initialValue1];   [modifiers] dataType memberName2 [= initialValue2];   // ...   // Methods   [modifiers] returnType methodName1([parameters]) {     // Method body   }   [modifiers] returnType methodName2([parameters]) {     // Method body   }   // ... } #salesforce #salesforcedeveloper #development #apex #trailhead

🔸 Updating 2 lakh (200,000) records using Apex code can be a challenging task, as it can lead to performance issues and even governor limit errors. However, I'll provide some guidance on how to approach this task. 🔸 👉 Approach 1: Using a Batch Apex Job Batch Apex is a scalable way to process large datasets in Apex. You can create a batch job to update the records in chunks, which helps avoid governor limits and performance issues. 👉 Approach 2: Using a Scheduled Apex Job If you don't need to update the records immediately, you can schedule a Apex job to run at a later time. This approach is useful when you need to update records during off-peak hours or when the system is less busy. ➡ Best Practices ➡When updating large datasets, make sure to: 0️⃣ Use bulkification to reduce the number of DML operations. 1️⃣ Use a try-catch block to handle any exceptions that may occur. 2️⃣ Monitor the job's progress and adjust the chunk size or batch size as needed. 3️⃣ Consider using a more efficient data access pattern, such as using a Map to store the records to update. 4️⃣ Test your code in a sandbox environment before running it in production. ⏭ Remember to always follow the Apex governor limits and best practices to avoid performance issues and errors. #salesforce #Trailhead #Ranger 🔹 Correct me if anything wrong in post 🔹
