Apex DML Operations

Introduction to Apex DML Operations

Apex DML (Data Manipulation Language) operations are integral to interacting with Salesforce data. These operations allow developers to perform actions such as insert, update, delete, and more on Salesforce records. Understanding how to effectively use these operations is crucial for any Salesforce developer looking to manage data within the platform.

The Insert Operation

The insert operation is used to add new records to Salesforce. When you perform an insert operation, you create new records in the database. Here’s how you can insert a new account record using Apex:

The Update Operation

The update operation modifies existing records in Salesforce. You must first retrieve the record, make the desired changes, and then apply the update operation. Below is an example that updates an account's name:

The Delete Operation

The delete operation removes records from Salesforce. Use this operation carefully, as it permanently deletes records. Here's an example of deleting an account:

Considerations and Best Practices

When performing DML operations in Apex, consider the following best practices:

• Use bulk DML operations to process multiple records at once, which is more efficient and helps avoid governor limits.
• Handle exceptions properly to manage errors gracefully.
• Consider using Database methods (covered in the next post) for more control over the DML process, including partial success scenarios.
