Asynchronous Apex in Salesforce : Future Methods

Asynchronous Apex in Salesforce : Future Methods Future Apex is used to run processes in a separate thread, at a later time when system resources become available. A future method runs in the background, asynchronously. You can call a future method for executing long-running operations, such as callouts to external Web services or any operation you’d like to run in its own thread, on its own time. You can also use future methods to isolate DML operations on different sObject types to prevent the mixed DML error. Each future method is queued and executes when system resources become available. That way, the execution of your code doesn’t have to wait for the completion of a long-running operation. A benefit of using future methods is that some governor limits are higher, such as SOQL query limits and heap size limits. You can call 50 future methods per transaction. Things to Remember: Methods are annotated with @future annotation. Use the future annotation to specify that th...

DML - Data Manipulation Language in Apex

What is DML in Apex ? Data Manipulation Language (DML) Create and modify records in Salesforce by using the Data Manipulation Language, abbreviated as DML. DML provides a straightforward way to manage records by providing simple statements to insert, update, merge, delete, and restore records. # DML Statements: The following DML statements are available. insert update upsert delete undelete merge Each DML statement accepts either a single sObject or a list (or array) of sObjects. Operating on a list of sObjects is a more efficient way for processing records. All those statements, except a couple, are familiar database operations. The upsert and merge statements are particular to Salesforce and can be quite handy. The upsert DML operation creates new records and updates sObject records within a single statement, using a specified field to determine the presence of existing objects, or the ID field if no field is specified. The merge statement merges up to three records...
