Hello,

A standard field record name can have data type of either auto number or text field with a limit of 80 chars.

For generating auto numbers, the format needs to be specified while defining the field and after that for every record that is added, the number will get auto generated. For example:-
Sr No-{1}
Sr No-{2}
Sr No-{3}

Hello,

There are three steps to add Aura components to a Visualforce page.

1.Add the Lightning Components for Visualforce JavaScript library to your Visualforce page using the <apex:includeLightning/> component.
2.Create and reference a Lightning app that declares your component dependencies.
3.Write a JavaScript function that creates the component on the page using $Lightning.createComponent().

Hello,

A lightning:select component creates an HTML select element. This component uses HTML optionelements to create options in the dropdown list, enabling you to select a single option from the list. Multiple selection is currently not supported.

This component inherits styling from select in the Lightning Design System.

Hello,

To access your security token, go to "Setup" (shows up in the upper right corner, under your name). In the left side menu column (under Personal Setup), open the drop-down item “My Personal Information.” The option to reset your security token will appear right under password reset option.

In the left side menu segment (under Personal Setup), open the drop-down thing "My Personal Information." The alternative to reset your security token will come up right under the password reset choice. Salesforce will send you an email containing your new security token. It's suggested that you save this email in a safe area so you don't need to reset your security token every time when you need it.

Hello,

By simply modifying the ContentType attribute on the <apex:page> tag, your Visualforce page code will automatically generate an Excel document. For example, the following code will create a table of Contact data for a given Account. After # in the contentType attribute value, it is the name of the excel file that will be generated and you also need to mention the file extension like .xls . For successfully running the below code you need to provide the valid account id in URL.

sample Vf code:-

<apex:page standardController="Account" contenttype="application/vnd.ms-excel#Demo Example.xls">
<apex:pageBlock title="Hello {!$User.FirstName}!">
You are viewing the {!account.name} account.
</apex:pageBlock>
<apex:pageBlock title="Contacts">
<apex:pageBlockTable value="{!account.Contacts}" var="contact">
<apex:column value="{!contact.Name}"/>
<apex:column value="{!contact.Email}"/>
<apex:column value="{!contact.Phone}"/>
</apex:pageBlockTable>
</apex:pageBlock>
</apex:page>

JavaScript remoting in Visualforce provides support for some methods in Apex controllers to be called via JavaScript.

JavaScript remoting has three parts:
The remote method invocation you add to the Visualforce page, written in JavaScript.
The remote method definition in your Apex controller class. This method definition is written in Apex, but there are few differences from normal action methods.
The response handler callback function you add to or include in your Visualforce page, written in JavaScript.
To use JavaScript remoting in a Visualforce page, add the request as a JavaScript invocation.

Hello ,

we use wrapper class in a apex controller class when there is a need of showing multiple dataTypes in a list so in case of apex we can use all three types of data types as following:-

1. primitive data types
2. Sobject data types
3. Collection data types i.e list,map,set.

SOQL:-

1. SOQL (Salesforce Object Query Language ) retrieves the records from the database by using “SELECT” keyword.
2. By Using SOQL we can know in Which objects or fields the data resides.
3. We can retrieve data from single object or from multiple objects that are related to each other.
4. We can Query on only one table.

SOSL:-
1. SOSL(Salesforce Object Search Language) retrieves the records from the database by using the “FIND” keyword.
2. By using SOSL, we don’t know in which object or field the data resides.
3. We can retrieve multiple objects and field values efficiently when the objects may or may not be related to each other.
4.We can query on multiple tables.

Status of a subscriber on a list (ListSubscribers) is not the same as the overall status in All Subscribers (Subscribers).

Lists are sub-sets of All Subscribers for which SFMC maintains status. Lists are sendable. Publication Lists are not.

You can be unsubscribed from a List and still be active in All Subscribers.

All Subscribers represents every subscriber in the entire Enterprise 2.0 account, not just a single business unit. Business unit membership and subscriber status are maintained in a hidden data view. The _Subscribers data view does not accurately reflect business unit status or membership.

acc.Contact_Recs__c = acc.Contacts.size();
accUpdateList.add(acc);
}
update accUpdateList;

Hello,

The only time you need Database.Stateful is when the execute method modifies a class variable in a way meant to be used across multiple execute methods or in the finish method. The majority of batches you will ever write will not need Database.Stateful. It's important to know that using Database.Stateful will harm your batch's performance, because the class will be serialized at the end of each execute method to update its internal state. This extra serialization results in longer execution time.
