How to bulkify code by combining soql queries?

// Step 3: Associate each record with the correct query result for ( Case newCase : Trigger.new) { // We’ll cover this in the next post! } } Now that we’ve combined our queries into one, we no longer have to worry about hitting the 100 SOQL query governor limit.

When do you need to bulkify trigger in Salesforce?

If you do that, your trigger is guaranteed to hit the governor limits. If you need to fetch large amount of data from an object (More than 50,000 records), then go for batch apex to pull that data, else you will again bump into another governor limit that wouldn’t allow you to fetch more than 50,000 records.

Is there a limit to how many soql queries apex can handle?

You also can’t expose logic to be re-used anywhere else in your org. Bulkifying Apex code refers to the concept of making sure the code properly handles more than one record at a time. An individual Apex request gets a maximum of 100 SOQL queries before exceeding that governor limit.

How many records can be returned by a soql query?

The total number of records that can be returned by SOQL queries in a request is 50,000. If returning a large set of queries causes you to exceed your heap limit, then a SOQL query for loop must be used instead. It can process multiple batches of records through the use of internal calls to query and queryMore

How to avoid using soql queries inside loops?

The #1 most common governor limit restricts you to 100 SOQL queries. Loops, especially those iterating over Trigger.new, will easily run 200+ queries and push you across the limit. How do we avoid using SOQL queries inside loops?

How many soql queries can I run per trigger?

This means that if each of your ten triggers runs 12 SOQL queries, you will run a total of 120 SOQL queries and go over the 100 SOQL query limit! This means you need to be extra conservative!

Which is a powerful feature of soql queries?

SOQL queries can be powerful. You can retrieve related records and check a combination of multiple conditions in one query. By using SOQL features, you can write less code and make fewer queries to the database.

How is the soql query connected to the trigger?

The SOQL query uses an inner query— (SELECT Id FROM Opportunities) —to get related opportunities of accounts. The SOQL query is connected to the trigger context records by using the IN clause and binding the Trigger.New variable in the WHERE clause— WHERE Id IN :Trigger.New.

When to use a soql query to find duplicate records?

An individual Apex request gets a maximum of 100 SOQL queries before exceeding that governor limit. So if this trigger is invoked by a batch of more than 100 Account records, the governor limit will throw a runtime exception

Which is an example of how to bulkify?

The good news is that 90% of people I interview do not understand how to bulkify, so this is your chance to stand out! Bulkification Example: Let’s analyze the governor limit for DML statements. This code is not bulkified and will go over the 150 DML statements limit: insert t; // You’ll get an error after the 150th opp!

Which is the best way to bulkify Apex code?

The following sections demonstrate the main ways of bulkifying your Apex code in triggers: operating on all records in the trigger, and performing SOQL and DML on collections of sObjects instead of single sObjects at a time. The SOQL and DML bulk best practices apply to any Apex code, including SOQL and DML in classes.

Which is a benefit of bulkifying your code?

The benefit of bulkifying your code is that bulkified code can process large numbers of records efficiently and run within governor limits on the Lightning Platform. These governor limits are in place to ensure that runaway code doesn’t monopolize resources on the multitenant platform.
