Developers PDI Reddit Questions

The result of the following code is that the record will not be created and an exception will be thrown. This is because the code is trying to insert a record with a null value for a required field, which violates the database constraints and causes a DMLException1. The code does not handle the exception with a try-catch block, so the exception will propagate to the caller and terminate the execution2. The debug log will show the exception message and stack trace, but the record will not be inserted in the database.

Java

Account a = new Account();

a.Name = null;

insert a;

The other options are incorrect. Option B is incorrect because the record will not be created and the debug log will show an exception, not a message. Option C is incorrect because the record will not be created and an error will be reported as an exception. Option D is incorrect because the record will not be created and an error will be reported as an exception. References:

A deployment script is a file that contains a series of commands or instructions to perform a deployment task, such as creating or updating metadata components, running tests, or validating changes. To run a script that deploys to a sandbox, the development team can use the following tools:

• Option A: VS Code. VS Code is a code editor that supports Salesforce development with extensions, such as Salesforce Extension Pack and Salesforce CLI Integration. VS Code allows the development team to write and execute deployment scripts using the Salesforce CLI commands or the SFDX commands palette. VS Code also provides features such as syntax highlighting, code completion, debugging, and source control integration.
• Option B: SFDX CLI. SFDX CLI is a command-line tool that enables the development team to interact with Salesforce orgs and perform various tasks, such as creating scratch orgs, retrieving and deploying metadata, running tests, and managing packages. SFDX CLI can run deployment scripts written in different formats, such as shell scripts, batch files, or JSON files.

References: The use of VS Code and SFDX CLI to run deployment scripts can be referenced in the Salesforce Platform Developer I learning documents, specifically in modules that cover Salesforce DX and deployment tools, such as:

• Deploy Changes to Orgs
• VS Code Basics

 The issue is that the value of the account type field is not being displayed correctly on the Visualforce page. This can be resolved by adding a getter method for the actType attribute in the custom controller. A getter method is used to retrieve the value of a private variable, ensuring that it’s read-only and cannot be modified by external classes or pages, thus maintaining encapsulation and security. References: The need for getter methods and their usage can be referenced in Apex basics where encapsulation, getters, and setters are discussed: Apex Basics & Database

The Create Records element allows you to create one or more new records of a specific object type in a Flow1. In this case, the developer needs to create a new Contact record and store its ID on the Opportunity record. The other options are either incorrect or unnecessary, as they do not create a new record or assign its ID to another record23. References:
