Can We Call Batch Class From Trigger in Salesforce?
Batch class can be called from trigger in Salesforce. This can be done using the Database.executeBatch() method. The method takes three parameters- the name of the batch class, the number of records to be processed in one batch, and the ID of the record on which processing starts.
- Create a batch class that contains the desired functionality
- In the trigger, specify when the batch class should be called
- For example, you might want to call it after an insert or update of a certain record type
- When the specified action occurs, the trigger will call the batch class and execute its methods

Can We Call Batch Apex from Another Batch Apex
Batch Apex is a powerful tool for processing large data sets in Salesforce. However, there are some things that Batch Apex can’t do on its own. One of these is calling another Batch Apex job.
There are two ways to call another Batch Apex job from an existing one. The first is to use the Database.executeBatch() method. This method takes a batch class as its parameter and executes it immediately.
The second way to call another Batch Apex job is to use the SchedulerService. schedule() method. This method schedules the execution of a batch class at a future time or interval specified by the user.

Can We Call Batch Class from Future Method
Salesforce provides the ability to schedule Apex classes to run at specific times using either the cron expressions in the Schedulable interface or Salesforce Process Builder. However, these methods require you to write a lot of code and can be difficult to maintain.
In some cases, you may want to call an existing batch class from a future method instead. The answer is yes, you can call batch classes from future methods. This can be useful if you need to schedule a batch job but don’t want to use Salesforce’s built-in scheduling tools.
It’s also worth noting that this approach can be used with any type of asynchronous Apex, not just batch jobs. To call a batch class from a future method, simply use the Database.executeBatch() method. This method accepts a single argument – the name of the batch class – and returns a Database.BatchableContext object.
For example: Database .
How to Run Batch Class in Salesforce
Salesforce batch classes are a great way to process large amounts of data. They can be used to perform complex data operations or to simply update records in bulk. But how do you actually run a batch class in Salesforce?
In this blog post, we’ll walk you through the steps needed to get your batch class up and running. First, navigate to the Apex Classes page in Salesforce. This can be found by going to Your Name > Setup > Develop > Apex Classes.
Next, click on the New button in the top right corner of the page. This will bring up a new Apex Class wizard. Enter a name for your class and choose “With sharing” or “Without sharing” as appropriate.
Then click on the “Batchable” checkbox and select “Database.” Finally, click on the “Generate Batch Header” button. Your new batch class will now be generated with all of the necessary boilerplate code included.
The next step is to add your own custom logic to the execute() method. This is where you will specify what actions should be taken when records are processed by your batch class. Once you have added your custom logic, save your changes and then open the Developer Console.
In the Execute Anonymous window, enter the following code: Database . executeBatch ( new myBatchClass ());
This will execute your batch class immediately against all of the records in your database that meet any criteria specified in your WHERE clause . You can also schedulebatch classesto run automatically at regular intervals by clicking onthe Schedule Batch buttonin Salesforce .
Can We Call Schedule Apex from Trigger
Salesforce provides a powerful tool for automating processes called Apex. One of the most useful features of Apex is its ability to schedule jobs to run at specific times. This can be extremely helpful when you need to perform an action on a large number of records, or when you want to ensure that a process runs regularly without manual intervention.
One question that we often get asked is whether it’s possible to call Schedule Apex from a trigger. The answer is yes! You can use the System.schedule() method to call Schedule Apex from a trigger.
This can be very useful if you want to automate some process that needs to run based on certain conditions being met in your data. For example, you could create a trigger that calls Schedule Apex whenever a record is created with a certain status value. To call Schedule Apex from a trigger, you will first need to create an apex class that implements the Schedulable interface.
This class will define when your job should run and what actions it should perform. Once you have created this class, you can then add a line of code to your trigger that calls the System.schedule() method and passes in your Schedulable class name and any required parameters. Your job will then be scheduled and will run automatically at the specified time!
Can a Trigger Call a Batch Class?
Yes, a trigger can call a batch class. In fact, this is a common pattern used to perform asynchronous processing in Salesforce. The reason for this is that when a record is saved via a trigger, the resources are not immediately available to process the record.
By calling a batch class, you can offload this work to be processed asynchronously, freeing up the resources for other requests.
How Do You Call a Batch Class in Salesforce?
Salesforce provides a powerful tool to automate business processes called batch Apex. Batch Apex lets you define a single job that can be broken up into multiple, smaller pieces and processed in parallel. This makes it an ideal tool for bulk data processing or any other process that needs to be run asynchronously on large sets of data.
To call a batch class in Salesforce, first create an instance of the class and then call the execute method. The execute method takes two parameters: a list of sObjects and a Database.BatchableContext object. The list of sObjects is used to determine which records will be processed by the batch class and the Database.BatchableContext object allows the batch class to access information about its execution context like job id, number of batches processed, etc.
Once you have created an instance of your batch class and called the execute method, Salesforce will take care of breaking up your job into smaller batches and processing them in parallel. You can monitor the status of your batch jobs from the Monitor Jobs page in Salesforce Setup.
Can We Call Class from Trigger?
Yes, we can call class from trigger. In fact, we can call any Apex code from a trigger. However, there are certain best practices that should be followed when doing so.
When calling a class from a trigger, it is important to consider the order of execution. The order of execution is the order in which Salesforce processes record events. This is important to understand because the records being processed by the trigger may not have been saved yet and thus may not contain all of the data that they will eventually have.
Another best practice to follow when calling a class from a trigger is to use batch Apex methods. Batch Apex allows you to process large numbers of records while still following governor limits. This is especially important when dealing with triggers because triggers can sometimes cause excessive database loads which can lead to performance issues.
Overall, calling a class from a trigger is perfectly fine as long as you take care to consider the order of execution and use batch Apex methods where appropriate.
Can We Call Batch Class from Queueable?
Yes, you can call batch class from Queueable. In fact, this is a recommended way to do it as it will allow you to avoid governor limits.
Salesforce provides a powerful tool for developers in the form of triggers. Triggers allow developers to execute custom code on specific events, such as when a record is created or updated. However, one common question that arises is whether it’s possible to call a batch class from a trigger.
The answer is yes, it is possible to call a batch class from a trigger in Salesforce. However, there are some important things to keep in mind when doing so. First, you’ll need to make sure that your batch class is set up correctly.
Second, you’ll need to consider the timing of when your batch class runs. And finally, you’ll need to be aware of any governor limits that may be in place.
