What does the query() function execute?

The query() function executes a SOQL (Salesforce Object Query Language) query against a specified object. This function is essential for retrieving records from Salesforce based on specific criteria. When you use query(), you can effectively fetch data and filter it according to the fields and conditions that you define in your SOQL statement.

SOQL allows developers to specify the exact data they need by querying one or more Salesforce objects and applying various filtering and sorting techniques. This function is commonly used in Apex code and other Salesforce integrations to interact with the database and gather necessary information, such as retrieving accounts, contacts, opportunities, or any custom objects.

Understanding this functionality is crucial for anyone working with Salesforce development and integration, as it enables efficient data access and ensures that applications can interact smoothly with Salesforce data.
