Use sObjects Because Apex is tightly integrated with the database, you can access Salesforce records and their fields directly from Apex. Every record in Salesforce is natively represented as an sObject in Apex. For example, the Acme account record corresponds to an Account sObject in Apex.

What is an sobject in Salesforce apex?
Every record in Salesforce is natively represented as an sObject in Apex. For example, the Acme account record corresponds to an Account sObject in Apex. The fields of the Acme record that you can view and modify in the user interface can be read and modified directly on the sObject as well.
What is an API object in Salesforce apex?
The API object name becomes the data type of the sObject variable in Apex. In this example, Account is the data type of the acct variable. The account referenced by the acct variable is empty because we haven’t populated any of its fields yet. There are two ways to add fields: through the constructor or by using dot notation.
What is uniqueness of sobjects in Salesforce?
Uniqueness of sObjects is determined by comparing the objects’ fields. For example, if you try to add two accounts with the same name to a set, with no other fields set, only one sObject is added to the set. If you add a description to one of the accounts, it is considered unique and both accounts are added to the set.
How are Salesforce Records represented in Salesforce apex?
Every record in Salesforce is natively represented as an sObject in Apex. For example, the Acme account record corresponds to an Account sObject in Apex.
What are sObjects in Apex?
Sobjects are standard or custom objects that stores record data in the force.com database. There is also SObject datatype in apex that is the programmatic representation of these SObjects. Developers referes to SObject and their fields by their API names. EXAMPLE: Account a = new Account();
What is the use of sObject in Salesforce?
The Account sObject is an abstraction of the account record and holds the account field information in memory as an object. Each Salesforce record is represented as an sObject before it is inserted into Salesforce. Likewise, when persisted records are retrieved from Salesforce, they're stored in an sObject variable.
What is dynamic apex in Salesforce?
Dynamic Apex enables developers to create more flexible applications by providing them with the ability to: Access sObject and field describe information. Describe information provides metadata information about sObject and field properties.
What is the relationship between sObjects and Salesforce records?
1Describe the relationship between sObjects and Salesforce records. I)The name of an sObject field in Apex is the label of the field in Salesforce. II) A custom object's API name and label are the same. III)Every record in Salesforce is natively represented as an sObject in Apex.
What is an SObjects?
sObject is the name of the generic abstract type that can be used to represent any persisted object type.
What is difference between sObject and object?

Sobjects are specific subtype that represents database records, including standard objects like Accounts and Cases, custom objects, custom settings, and custom metadata.
What are some of the advantages of dynamic apex?
Dynamic Apex enables developers to create more flexible applications by providing them with the ability to “Access sObject and field describe information”, “Write Dynamic SOQL Queries”, “Write Dynamic SOSL Queries” and “Dynamic DML”.
What is schema in Apex?
Schema is a Namespace which is referred as Database. This namespace contains some classes and their methods to provide metadata information of Schema. Schema class deals with both bulk and single record means you can fetch all objects' names at once or a single object name.
What is static SOQL?
Static SOQL is one which you write in square brackets. It is good to use when you didn't have any dynamic changes in the soql query. For e.g when the fields names or where conditions is needed to be defined dynamically we didn't use statis soql. Then we need to use dynamic soql. Dynamic SOQL is dynamic query creation.
What is a key benefits of asynchronous processing?
One of the main benefits of running asynchronous Apex is higher governor and execution limits. For example, the number of SOQL queries is doubled from 100 to 200 queries when using asynchronous calls.
What is SOSL in Salesforce?
Salesforce Object Search Language (SOSL) is a Salesforce search language that is used to perform text searches in records. Use SOSL to search fields across multiple standard and custom object records in Salesforce. SOSL is similar to Apache Lucene.
Why would a developer use test startTest () and test stopTest ()?
These methods, Test. startTest and Test. stopTest, are used when testing governor limits. Or in other words, executing test scenarios with a larger data set.
What is sObject clone method?
Salesforce sObject class has a method called clone() which creates a copy of the sObject record. This method has four Boolean type optional parameters. preserveId: Determines whether the ID of the original object is kept or cleared in the duplicate. If set to true, the ID is copied to the duplicate.
How do I query sObject in Salesforce?
If you have the sobject name in a string, e,g, 'sobjname', you can then query back the record via something like: String queryStr='select id from ' + sobjname; List
What is generic sObject in Salesforce?
Generic sObject means, it can be of any persisted SFDC objects type. For ex: Vehicle is generic type and Car, Motor Bike all are concrete types of Vehicle. In SFDC,sObject is generic and Account, Opportunity, CustomObject__c are its concrete type.
What is a key benefit of asynchronous processing?
One of the main benefits of running asynchronous Apex is higher governor and execution limits. For example, the number of SOQL queries is doubled from 100 to 200 queries when using asynchronous calls.
addError (errorMsg)
Marks a trigger record with a custom error message and prevents any DML operation from occurring.
addError (errorMsg, escape)
Marks a trigger record with a custom error message, specifies if the error message should be escaped, and prevents any DML operation from occurring.
addError (exceptionError)
Marks a trigger record with a custom error message and prevents any DML operation from occurring.
addError (exceptionError, escape)
Marks a trigger record with a custom exception error message, specifies whether or not the exception error message should be escaped, and prevents any DML operation from occurring.
addError (errorMsg)
Places the specified error message on a trigger record field in the Salesforce user interface and prevents any DML operation from occurring.
addError (errorMsg, escape)
Places the specified error message, which can be escaped or unescaped, on a trigger record field in the Salesforce user interface, and prevents any DML operation from occurring.
addError (fieldName, errorMsg)
Dynamically add errors to fields of an SObject associated with the specified field name.
