1. What is Apex
Ans: It is the in-house technology of salesforce.com which
is similar to Java programming with object oriented concepts and to write our
own custom logic.
2. What is S-Control ?
Ans: S-Controls are the predominant salesforce.com widgets
which are completely based on Javascript. These are hosted by salesforce but
executed at client side. S-Controls are superseded by Visualforce now.
3. What is a Visualforce Page ?
Ans: Visualforce is the new markup language from salesforce,
by using which, We can render the standard styles of salesforce. We can still
use HTML here in Visualforce. Each visualforce tag always begins with “apex”
namespace. All the design part can be acomplished by using Visualforce Markup
Language and the business logic can be written in custom controllers associated
with the Page.
4. Will Visual force still supports the merge fields usage
like S-control ?
Ans: Yes. Just like S-Controls, Visualforce Pages support
embedded merge fields, like the {!$User.FirstName} used in the example.
5. Where to write Visualforce code ?
Ans: You can write the code basically in 3 ways.
setup->App Setup->Develop->Pages and create new
Visulaforce page.
Setup -> My Personal Information -> Personal
Information -> Edit check the checkbox development mode. When you run the
page like this, https://ap1.salesforce.com/apex/MyTestPage. you will find the
Page editor at the bottom of the page. You can write you page as well as the
controller class associated with it, there it self.
Using EclipseIDE you can create the Visulaforce page and
write the code.
6.What are Apex Governor Limits?
Ans: Governor limits are runtime limits enforced by the Apex
runtime engine. Because Apex runs in a shared, multitenant environment, the
Apex runtime engine strictly enforces a number of limits to ensure that code
does not monopolize shared resources. Types of limits that Apex enforces are
resources like memory, database resources, number of script statements to avoid
infinite loops, and number of records being processed. If code exceeds a limit,
the associated governor issues a runtime exception.

9. How to schedule export or take the backup of salesforce?
Ans: Click here to know.
10. Do governor limits apply to sandbox instances?
Ans : Governor limits do apply to all Salesforce instances (trial, developer, production or sandbox environments). However code coverage and successful execution of test classes is only enforced when deploying to a production environment.
11. What is difference in ISNULL and ISBLANK?
Ans: ISNULL:
- Determines if an expression is null (blank) and returns TRUE if it is. If it contains a value, this function returns FALSE.
- Text fields are never null, so using this function with a text field always returns false. For example, the formula field IF(ISNULL(new__c) 1, 0) is always zero regardless of the value in the New field. For text fields, use the ISBLANK function instead.
- Multi-select picklist fields are never null in s-controls, buttons, and email templates, so using this function with a multi-select picklist field in those contexts always returns false.
- Empty date and date/time fields always return true when referenced in ISNULL functions.
- Choose Treat blank fields as blanks for your formula when referencing a number, percent, or currency field in an ISNULL function. Choosing Treat blank fields as zeroes gives blank fields the value of zero so none of them will be null.
- Merge fields can be handled as blanks, which can affect the results of components like s-controls because they can call this function.
- When using a validation rule to ensure that a number field contains a specific value, use the ISNULL function to include fields that do not contain any value. For example, to validate that a custom field contains a value of ’1,’ use the following validation rule to display an error if the field is blank or any other number: OR(ISNULL(field__c), field__c<>1)
ISBLANK:
- Determines if an expression has a value and returns TRUE if it does not. If it contains a value, this function returns FALSE.
- Use ISBLANK instead of ISNULL in new formulas. ISBLANK has the same functionality as ISNULL, but also supports text fields. Salesforce.com will continue to support ISNULL, so you do not need to change any existing formulas.
- A field is not empty if it contains a character, blank space, or zero. For example, a field that contains a space inserted with the spacebar is not empty.
- Use the BLANKVALUE function to return a specified string if the field does not have a value; use the ISBLANK function if you only want to check if the field has a value.
- If you use this function with a numeric field, the function only returns TRUE if the field has no value and is not configured to treat blank fields as zeroes.
12. Is it possible to write the Apex code from user Interface?
Ans: You can add, edit, or delete Apex using the Salesforce.com user interface only in a Developer Edition organization, a Salesforce.com Enterprise Edition trial organization, or sandboxorganization. In a Salesforce.com production organization, you can only make changes to Apex by using the Metadata API ,
deploycall, the Force.com IDE, or theForce.com Migration Tool. The Force.com IDE and Force.com Migration Tool are free resources provided by salesforce.com to support its users and partners, but are not considered part of our Services for purposes of the salesforce.com Master Subscription Agreement.
13. When you can’t add Time dependent action in Workflow rule?

18. How many types of the relationship fields available in Salesforce>
Ans :
- Master Detail
- Many to Many
- Lookup
- Hierarchical
19. How to create many to many relationships between object?
Creating many to many relationship in salesforce is little tricky. You cannot create this type of relationship directly. Follow below steps to create this type of relationship.
Create both objects which should be interlinked.
Create one custom object (also called as junction object), which should have autonumber as unique identification and create two master relationships for both objects, no need create tab for this object.
Now on both object, add this field as related list.
- Old record loaded from database (or initialized for new inserts)
- New record values overwrite old values
- System Validation Rules
- All Apex “before” triggers (EE / UE only)
- Custom Validation Rules
- Record saved to database (but not committed)
- Record reloaded from database
- All Apex “after” triggers (EE / UE only)
- Assignment rules
- Auto-response rules
- Workflow rules
- Escalation rules
- Parent Rollup Summary Formula value updated (if present)
- Database commit
- Post-commit logic (sending email)
21. If one object in Salesforce have 2 triggers which runs “before insert”. Is there any way to control the sequence of execution of these triggers?
Ans : Salesforce.com has documented that trigger sequence cannot be predefined. As a best practice create one trigger per object and use comment blocks to separate different logic blocks. By having all logic in one trigger you may also be able to optimize on your SOQL queries.

23. How to delete the users data from Salesforce?
Ans : To delete the Users Data go to Setup | Administration Setup | Data Management | Mass Delete Record, from there select the objects like Account, Lead etc and in criteria select the users name and delete all records of that user related to particular object.
24. How to restrict the user to see any record, lets say opportunity?
Ans : set up opportunity sharing to be private. If both users are admins or have view all records on opportunity, then that overrides private sharing.
25. What is the difference between trigger.new and trigger.old in Apex – SFDC?
Ans :
Trigger.new :
Returns a list of the new versions of the sObject records.
Note that this sObject list is only available in insert and update triggers, and the records can only be modified in before
triggers.
Trigger.old :
Returns a list of the old versions of the sObject records.
Note that this sObject list is only available in update and delete
triggers.
26. How to restrict any Trigger to fire only once ?
Ans:
Triggers can fire twice, once before workflows and once after workflows, this is documented at
http://www.salesforce.com/us/developer/docs/apexcode/ Content/ apex_triggers_order_of_execution.htm:
“The before and after triggers fire one more time only if something needs to be updated. If the fields have already been set to a value, the triggers are not fired again.”
Workaround:
Add a static boolean variable to a class, and check its value within the affected triggers.
1 | public class HelperClass { |
2 | public static boolean firstRun = true; |
3 | } |
4 | trigger affectedTrigger on Account (before delete, after delete, after undelete) { |
5 | if(Trigger.isBefore){ |
6 | if(Trigger.isDelete){ |
7 | if(HelperClass.firstRun){ |
8 | Trigger.old[0].addError('Before Account Delete Error'); |
9 | HelperClass.firstRun=false; |
10 | } |
11 | } |
12 | } |
13 | } |
27. What is difference between WhoId and WhatId in the Data Model of Task ?
Ans :
WhoID refers to people things. So that would be typically a Lead ID or a Contact ID
WhatID refers to object type things. That would typically be an Account ID or an Opportunity ID
28. Where is the option of the report for the “Custom Object with related object” and what are the condition to generate related reports?
Ans :
If the parent object is the standard object provided by the salesforce like “Account”, “Contact” then the report will be in there section with related custom object.
If both objects are the custom then the report will be in “Other Reports” Sections.
Following are the conditions to get the report of related objects:
- On both the objects, Reports option must be enable.
- The relationship between both of them must be “Master – detail relationship”.

In lookup, if we delete master records, child records will not be deleted.
In master-detail, if we delete master records, child records will also be deleted.
Child record is mandatory for Master-Detail.
48.What is an External Id?
Ans: External Id is an id that can be given to any field in an object. An external id will be generated on the field that we mention.

Ans: Trigger is a piece of code that is executed before or after a particular field of certain type is inserted, updated or deleted.
Bulk Trigger: All triggers are bulk triggers by default, and can process multiple records at a time. You should always plan on processing more than one record at a time.
Bulk triggers can handle both single record updates and bulk operations like:
Data import
Mass actions, such as record owner changes and deletes
Recursive Apex methods and triggers that invoke bulk DML statements.
Recursive trigger:
ActionSupport: A component that adds AJAX support to another component, allowing the component to be refreshed asynchronously by the server when a particular event occurs, such as a button click or mouseover.
ActionFunction: A component that provides support for invoking controller action methods directly from JavaScript code using an AJAX request.
ActionPoller: A timer that sends an AJAX update request to the server according to a time interval that you specify.
69.What is Batch Apex? How can you implement Batch Apex?(Dynamic Apex)
Ans: Batch Apex gives you the ability to operate over large amounts of data by chunking the job into smaller parts, thereby keeping within the governor limits.
Using batch Apex, you can build complex, long-running processes on the Force.com platform. For example, you could build an archiving solution that runs on a nightly basis, looking for records past a certain date and adding them to an archive.
70.What is a Callout method? How does it invoke, how many methods available in Classes and Triggers?
Ans: It is used to invoke the External services HTTP or web services.
An Apex callout enables you to integrate your Apex with an external service by making a call to an external Web service or sending a HTTP request from an Apex script and then receiving the response. Apex provides integration with Web services that utilize SOAP and WSDL, or HTTP services (RESTful services).
71.What is a difference between System log and debug log?
Ans: System Log console is a separate window that displays debugging information, as well as its cumulative limits and source code. It can be considered a context-sensitive execution viewer showing the source of an operation, what triggered that operation, and what occurred afterward. Use the System Log console to view debug logs that include database events, Apex processing, workflow, and validation logic.
Debug log records database operations, system processes, and errors that occur when executing a transaction or while running unit tests. The system generates a debug log for a user every time that user executes a transaction that is included in the filter criteria.
SOQL: Salesforce.com Object Query Language
SOSL: Salesforce.com Object Search Language
72.What is a Force.com IDE?

73.What is a Managed Package and Unmanaged package?
Ans: Unmanaged vs. Managed
Managed packages are AppExchange packages that can be upgraded in the installer's organization. They differ from unmanaged packages in that some components are locked, allowing the upgrade process. Unmanaged packages do not include locked components and can not be upgraded.
Before the Winter '07 release, all packages were unmanaged. Now, you can convert an unmanaged package to managed to ensure your installed users get upgrades.
Unmanaged Package Managed Package
What Completely Editable by Developer and Installer
Can NOT be upgraded Certain Components are locked
No Destructive Changes to app
Supports Seamless Upgrading
Supports LMA for Managing Installs
When to Use 1:1 Distribution
Extensive Modification Required 1:Many Distribution
Commerical Intent
Foresee Upgrades
Editions Supported All Editions can create Unmanaged Packages ONLY Developer Edition can create Managed Packages
Managed packages differ from unmanaged packages in many other ways. Before creating managed packages, here are a few things to consider:
You must use a Developer Edition organization to create and work with a managed package.
A Developer Edition organization can contain a single managed package and many unmanaged packages.
You must register a Namespace Prefix - A Namespace Prefix is a series of characters prefixed to your Custom Objects and Fields to prevent conflict when installed in another salesforce.com org.
When you release a managed package, meaning it is uploaded with the Managed - Released option selected, the properties of its components change to prevent developers and installers from making harmful changes. For a list of each package component type and their properties, see Properties of Managed Packages. If you do not want to offer upgrades to your package, consider keeping it unmanaged.
If you plan to release your app as a Managed Package, please read out guide on Planning the Release of Managed Packages
If you already have a Unmanaged Package and you'd like to convert it to Managed, please review the following: Converting Unmanaged Packages to Managed
Now that you understand the difference and benefits of each type of package, let's see how easy it is to make your Unmanaged package from above into a Managed Package.

74.What are the rules Criteria to create a work flow? How many ways to fire a work flows and when should those available? What are the actions in work flow?
Ans: Criteria that cause salesforce.com to apply the workflow rule.
Immediate actions that execute when a record matches the criteria.
Time-dependent actions that salesforce.com queues when a record matches the criteria, and executes according to time triggers.
In 2 ways,
1. Immediate action: when criteria matches record then workflow will be fired immediately.
2. Timedependent action: Fires according to time triggers.
Tasks - Assign a new task to a user, role, or record owner.

77. What is test coverage code % for the classes and triggers and what is the test method syntax?
Ans: 75%.
78.Types of Triggers and what is a Bulk Trigger?
Ans: All triggers are bulk triggers by default, and can process multiple records at a time. You should always plan on processing more than one record at a time.
Bulk triggers can handle both single record updates and bulk operations like:
Data import
Bulk Force.com API calls
Mass actions, such as record owner changes and deletes
Recursive Apex methods and triggers that invoke bulk DML statements.

80. What is a Wrapper Class in S.F?
Ans: A wrapper class is a class whose instances are collections of other objects.
81. What are formula and Rollup Summary fields and Difference between them? When should Rollup- Summary field enable?
Ans: Formula: A read-only field that derives its value from a formula expression that we define. The formula field is updated when any of the source fields change.
Rollup Summary: A read-only field that displays the sum, minimum, or maximum value of a field in a related list or the record count of all records listed in a related list.
Difference is below:
Formula fields calculate values using fields within single record, roll-up summary fields calculate values from a set of related records.
When we give the master-detail relationship it get’s enable to the master object
Ans: AJAX is primarily used for partial page updates in Visualforce. In s-controls, the AJAX toolkit was the soap (XML over HTTP) client that gave you access to the force.com Web Services API.

Ans: Trigger is a piece of code that is executed before or after a particular field of certain type is inserted, updated or deleted.
Bulk Trigger: All triggers are bulk triggers by default, and can process multiple records at a time. You should always plan on processing more than one record at a time.
Bulk triggers can handle both single record updates and bulk operations like:
Data import
Mass actions, such as record owner changes and deletes
Recursive Apex methods and triggers that invoke bulk DML statements.
Recursive trigger:
ActionSupport: A component that adds AJAX support to another component, allowing the component to be refreshed asynchronously by the server when a particular event occurs, such as a button click or mouseover.
ActionFunction: A component that provides support for invoking controller action methods directly from JavaScript code using an AJAX request.
ActionPoller: A timer that sends an AJAX update request to the server according to a time interval that you specify.
69.What is Batch Apex? How can you implement Batch Apex?(Dynamic Apex)
Ans: Batch Apex gives you the ability to operate over large amounts of data by chunking the job into smaller parts, thereby keeping within the governor limits.

73.What is a Managed Package and Unmanaged package?
Ans: Unmanaged vs. Managed
Managed packages are AppExchange packages that can be upgraded in the installer's organization. They differ from unmanaged packages in that some components are locked, allowing the upgrade process. Unmanaged packages do not include locked components and can not be upgraded.
Before the Winter '07 release, all packages were unmanaged. Now, you can convert an unmanaged package to managed to ensure your installed users get upgrades.
Unmanaged Package Managed Package
What Completely Editable by Developer and Installer
Can NOT be upgraded Certain Components are locked
No Destructive Changes to app
Supports Seamless Upgrading
Supports LMA for Managing Installs
When to Use 1:1 Distribution
Extensive Modification Required 1:Many Distribution
Commerical Intent
Foresee Upgrades
Editions Supported All Editions can create Unmanaged Packages ONLY Developer Edition can create Managed Packages
Managed packages differ from unmanaged packages in many other ways. Before creating managed packages, here are a few things to consider:
You must use a Developer Edition organization to create and work with a managed package.
A Developer Edition organization can contain a single managed package and many unmanaged packages.
You must register a Namespace Prefix - A Namespace Prefix is a series of characters prefixed to your Custom Objects and Fields to prevent conflict when installed in another salesforce.com org.
When you release a managed package, meaning it is uploaded with the Managed - Released option selected, the properties of its components change to prevent developers and installers from making harmful changes. For a list of each package component type and their properties, see Properties of Managed Packages. If you do not want to offer upgrades to your package, consider keeping it unmanaged.
If you plan to release your app as a Managed Package, please read out guide on Planning the Release of Managed Packages
If you already have a Unmanaged Package and you'd like to convert it to Managed, please review the following: Converting Unmanaged Packages to Managed
Now that you understand the difference and benefits of each type of package, let's see how easy it is to make your Unmanaged package from above into a Managed Package.

Rollup Summary: A read-only field that displays the sum, minimum, or maximum value of a field in a related list or the record count of all records listed in a related list.
Difference is below:
Formula fields calculate values using fields within single record, roll-up summary fields calculate values from a set of related records.
When we give the master-detail relationship it get’s enable to the master object
82.What are expressions used in pages to bind in controllers?
Ans: Using methods we can bind.
Getter:Will return value from controller to vf page

Ans: All standard and custom objects that can be accessed via the API have associated controllers
85.What is included with each standard controller?
Ans: Data: the fields for the associated object record that are API accessible, including the related records (5 up/1 down). Actions: save, delete, view, edit, cancel.
86.When do you need to go beyond a standard controller and code custom Apex?
Ans: If you need data beyond the limits of what is available in the standard controller or actions that go beyond the provided standard actions.
87.Compare and contrast custom controllers and controller extensions. How are they the same? How are they different?
Ans: Both allow for custom code to be used, allowing for custom data sets and custom actions. Extensions leverage the existing data and actions within a standard or custom controller. Custom controllers must contain all data and actions that need to be executed by the page. Extensions that extend standard controller allow for the pages which use those extensions to be used in custom buttons, standard button overrides, and over declarative features.
88.What identifies a controller as being an extension?
Ans: The controller must declare a constructor which takes another controller explicitly. For example: public myControllerExtension(ApexPages.StandardController stdController) {this.acct = (Account)stdController.getRecord(); }
89.Why are properties helpful in controllers?
Ans: Properties can automatically create standard getters and setters while still allowing for their customizations. They save you from both writing the tedious code and reading the clutter when reviewing code.
90.In what order do methods fire within a controller?
Ans:The only rule is that setters fire before action methods. Aside from that, there is no guaranteed order.
91.What are some Apex classes that are commonly used within controllers?
Ans: StandardController, SelectOption, PageReference, Message, etc.
92.How are wizard controllers different from other controllers?
Ans: The two main issues is that they must handle multiple pages and they must maintain the state across those pages.
93.What are the effects of using the transient key word?
Ans: The transient key word prevents the data from being saved into the view state. This should be used for very temporary variables.
94.When is a component controller required for custom components?
Ans: A component controller is required when business logic is required to decide how to render the component.
95..What kind of content can be included in a Visualforce page?
Ans:Any content that can be rendered in a browser (HTML, JavaScript, etc.).
96.What do {!expressions} refer to when used in Visualforce components
Ans: Expressions refer to either data or actions that are made available to the page from the controller

Ans: Basically, via links, buttons, tabs, and inline frames.
98.Is it always necessary to know Apex to create Visualforce pages? When does it become necessary?
Ans:No, it is not always necessary. You can use standard controllers and VF component tags to accomplish quite a bit. Apex becomes necessary when you need either a custom set of data or custom actions to be available from the page.
99.What are attributes? What is the syntax for including them?
Attributes are modifiers to the main tag that belong after the tag name in the start tag. The syntax is attributeName=“attributeValue”

110.What are the different AJAX action tags? What does each do?
Ans:
- actionStatus: used to display start and stop statuses of
