Learn Apex 20% and Code 80% - Salesforce coding made Easy

Learn a universal pseudocode recipe for any Salesforce requirement, using a generic code format with collection, for-each loops, logic, and conditionals to decide when to code versus configure.

Learn the basics of soql, Salesforce's object query language, focusing on single-object queries against standard or custom objects. Write select-from-where statements to fetch account records by industry.

Master soql implementation by writing and executing queries in the Salesforce developer console, selecting fields, filtering with where, using and not conditions, and applying limit and aggregate count.

Learn how to query a tail/child using s.o.q.l to fetch parent fields, including lookup and master-detail relationships, with a singer and song example in a music app.

Master soql for parent-child data in salesforce by querying the song object and its parent lookups. Fetch fields like name, duration, singer, instagram, and date of birth.

Explore why variables matter in Apex by examining how queries return song records under different conditions and how collections help hold varying results.

Understand how variables hold values in memory, use temporary variables for swaps, and why data types determine memory size and space allocation in Apex.

Explore the difference between primitive and user-defined data types and learn to declare an integer variable, assign a value with the assignment operator, and terminate the statement with a semicolon.

Explore data types like integer, boolean, string, date, time, and the role of collections in Apex, including lists and sets, to hold dynamic records in Salesforce coding.

Explore list collections in Apex, learn when to use lists, sets, and maps, and create a list of integers, add items, and check its size and contents.

Improve code readability and maintainability by using comments. Learn how single-line and multi-line comments help convey intent, skip or explain code, and identify the exact lines to modify in apex.

Master Apex set collections by comparing lists and sets, and learn why sets ignore duplicates, how size differs, and how to use unique variables within a single transaction.

Create a playlist using a list collection in Apex by querying six song records, storing them in a list, and understanding a memory block and API names for standard objects.

Explore map collections in Apex: create key–value pairs, ensure unique keys, and retrieve values with get. Use a classroom register example to illustrate map behavior and duplicates.

Learn how to use Apex to perform dml operations—insert, update, and delete—on Salesforce records, including creating a new record for a custom object single (a singer) and understanding automation motivations.

Learn how to perform update dml in Apex by retrieving a specific record with a query, modifying fields like bio and Instagram feed, and saving the updated record.

Learn how to delete a single record using DML in Salesforce, by passing the record from a query and using the record's ID for precise removal.

Use the for each loop in Apex to update all singer bios by iterating over a collection of records and applying changes to each one.

Learn how bulkification in Apex guards against governor limits by collecting records in a single collection and performing bulk updates, avoiding DML inside loops and handling multi-record operations efficiently.

Apply conditional statements to decide whether to update a singer’s bio based on the number of songs sung; if none, keep the bio unchanged.

Master conditional statements to drive code flow, checking if the bio field is populated and updating or appending accordingly. Use isEmpty, not equals, and if-else blocks to manage collection updates.

Explore how to structure logic using a top secret approach with collections, queries, and conditional statements to fetch, modify, and process records.
