Working with Data in Apex – Part 2, Advanced SOQL and DML.
Course Description
Ready to take your Salesforce development skills to the next level? This intermediate-level course is designed to deepen your understanding of SOQL (Salesforce Object Query Language) and DML (Data Manipulation Language) operations in Apex, equipping you with the knowledge to efficiently manage and manipulate Salesforce data.
Part 2 of the “Working with Data in Apex” series builds on the fundamentals covered in Part 1, diving into more advanced query techniques, dynamic SOQL, and complex DML operations. Through hands-on examples, you will learn to optimize your code and handle real-world data manipulation scenarios with confidence.
Along with practical demonstrations, this course provides valuable resources such as slides, screenshots, and practice exercises to reinforce your learning and ensure you’re well-prepared for Salesforce developer roles.
Who Is This Course For?
This course is ideal for:
Salesforce Developers: Developers looking to expand their expertise in SOQL queries and DML operations.
Salesforce Admins and Developers-in-Training: Admins transitioning to development roles who need a deeper understanding of working with data in Apex.
Salesforce Developer Interview Prep: Those preparing for advanced Salesforce Developer interviews.
Students of Apex Programming: Anyone who has completed basic Apex courses (Level 1-5) and wants to master data querying and manipulation.
What Will You Learn in This Course?
Variable Binding in SOQL: Safeguard your queries with variable binding to prevent SOQL injection and enhance dynamic query capabilities.
Aggregate Functions in SOQL: Use aggregate functions like COUNT(), SUM(), and MAX() to summarize and report on Salesforce data efficiently.
GROUP BY and HAVING Clause: Master advanced SOQL techniques to group and filter records based on specific criteria.
SOQL For Loops: Learn how to work with large data sets using SOQL for loops without hitting governor limits.
Dynamic SOQL: Build flexible SOQL queries dynamically at runtime for more complex data retrieval scenarios.
DML Operations: Perform advanced data manipulation in Salesforce using the INSERT, UPDATE, UPSERT, DELETE, UNDELETE, and MERGE statements.
Bulk DML Operations: Optimize bulk operations for improved performance and handle large datasets effectively.
Salesforce Database Methods: Use Salesforce’s Database class methods to control DML operations with fine-grained error handling and partial success processing.
Topics Covered in This Course:
SOQL (Salesforce Object Query Language):
Variable Binding in SOQL: Learn how to securely pass variables into your SOQL queries, protecting your code from SOQL injection attacks.
Aggregate Functions: Discover how to use aggregate functions like COUNT(), AVG(), SUM(), MIN(), and MAX() to perform complex calculations on Salesforce data.
GROUP BY and HAVING Clauses: Understand how to group your query results and filter them using the HAVING clause, refining your data analysis.
SOQL For Loops: Use SOQL for loops to efficiently query and process large volumes of data without exceeding governor limits.
Dynamic SOQL: Build SOQL queries dynamically at runtime, allowing greater flexibility in querying data based on user input or application logic.
DML (Data Manipulation Language) Operations:
INSERT, UPDATE, and UPSERT Statements: Learn how to add new records, modify existing ones, and upsert (insert or update) records using efficient DML operations.
DELETE and UNDELETE Statements: Master the process of deleting records safely, recovering them from the recycle bin using the UNDELETE statement.
MERGE Statement: Combine duplicate records in Salesforce using the MERGE statement, handling related records seamlessly.
Bulk DML Operations: Optimize bulk inserts, updates, and deletes to handle thousands of records without exceeding Salesforce’s governor limits.
Database Methods: Learn to use Database.insert(), Database.update(), Database.delete(), and Database.upsert() for fine-tuned control over DML operations, including partial success and error handling.
What You Will Get from This Course:
In-Depth Concept Explanations: Advanced SOQL and DML topics are broken down into easy-to-understand concepts with practical examples to help you apply them.
Hands-On Exercises: Each topic comes with practical examples and exercises to test your understanding and improve your coding skills.
Valuable Resources: Get access to slides for quick revision and screenshots of practical implementations for easy review.
16 Practice Questions: Self-evaluation exercises designed to help you understand key concepts and test your knowledge after each section.
Interview Preparation: Prepare for Salesforce Developer interviews with a solid understanding of SOQL and DML, ensuring you’re ready to tackle advanced data manipulation challenges.
Cautionary Tips: Learn important considerations and best practices for working with large data sets, avoiding governor limits, and ensuring data integrity.
Pre-Requisites:
To get the most out of this course, it’s recommended that you have:
Completed Part 1 of the “Working with Data in Apex” series or have a basic understanding of SOQL and sObjects.
Familiarity with the Apex Programming Levels 1-5 (Part I) series for foundational knowledge in Apex programming.
Course Outcomes:
By the end of this course, you will have a thorough understanding of how to efficiently query and manipulate Salesforce data using advanced SOQL and DML techniques. You’ll be able to write optimized queries, perform bulk data operations, and handle real-world data challenges in Salesforce, positioning you for success as a Salesforce developer.
