Salesforce Apex Trigger and Trigger Design Pattern

Learn how to write a Salesforce trigger using setup, object manager, or developer console; understand best practice of one trigger per object and selecting events such as insert.

Identify and apply trigger events in Salesforce, including before and after insert, update, and delete, to control data handling on accounts and related records.

Learn how to use Salesforce Apex trigger context variables to identify before or after events and the triggering operation (insert, update, delete, undelete), and manage multiple records.

Explore using Apex trigger context variables to run specific logic only during before or after events (insert, update, delete, undelete) and combine conditions for context-aware trigger design.

Learn to access records in Salesforce Apex triggers with trigger context variables, covering before/after insert, update, and delete, and using new map and old map for data references.

Create a before insert trigger on the account object to set rating when industry is banking or healthcare. Use bulk processing to handle multiple records and learn trigger context variables.

Implement a Salesforce Apex trigger on the contact object to auto-populate the description before insert, using a single trigger per object and a handler class, leveraging trigger context variables.

See a practical apex trigger example that updates contact fields during an update, handles before and during contexts, uses a separate class method and context variables to map usernames.

Explore relationship queries in apex triggers with a practical example of account and contact relationships, showing how to navigate one-to-many links, access parent data, and handle bulk inserts.

Explore how to implement Salesforce triggers, including before insert checks for duplicate account names, and use aggregate queries and group by to validate data in bulk while optimizing performance.

Explore Apex trigger patterns for bulk processing, handling account and contact changes, with maps and lists, implementing trigger handlers and utility classes for insert, update, and delete operations.
