What is the difference between apex:dataTable and apex:pageBlockTable

Only standard style sheets can be used in apex:pageBlockTable tag in Visualforce page. <apex:pageBlockTable> must be contained in <apex:pageBlock> or <apex:pageBlockSection>.

If we want to add custom style sheets we have to use apex:dataTable tag in Visualforce page.

Sample Code:

Visualforce page:

<apex:page controller="sample" sidebar="false" >
<style type="text/css">
    .outBorder
    {
        border:3px outset black;
    }
   
    .inBorder
    {
        border-top:3px dotted black;
        border-left:3px dotted black;
    }   
</style>
    <apex:pageBlock title="Pageblock Table">
        <apex:pageblockTable value="{!acc}" var="a">
            <apex:column value="{!a.Name}"/>
            <apex:column value="{!a.Name}"/>           
        </apex:pageblockTable>
    </apex:pageBlock>
   
    <apex:pageBlock title="Data Table">
        <apex:dataTable value="{!acc}" var="a" styleClass="outBorder" width="550px">
            <apex:column styleClass="inBorder">
                <apex:facet name="header">Account Name</apex:facet>
                <apex:outputText >{!a.Name}</apex:outputText>
            </apex:column>      
            <apex:column styleClass="inBorder">
                <apex:facet name="header">Account Number</apex:facet>
                <apex:outputText >{!a.AccountNumber}</apex:outputText>
            </apex:column>             
        </apex:dataTable>
    </apex:pageBlock>   
</apex:page>

Apex Controller:

 public with sharing class sample
{

    public List<Account> acc {get;set;}
    public sample()
    {
        acc = [SELECT Name, AccountNumber FROM Account];
    } 
   
}

Dynamic Dashboard in Salesforce

 Dashboard which is running under current logged in user permission are known as “Dynamic Dashboard”.

A dynamic dashboard displays the data of the user viewing it rather than the data of a specified running user. Optionally, authorized users can change the running user directly from the dashboard view page.

Users automatically view dashboard as themselves. Users with "View My Team's Dashboards" permission can change view to another user.

1. Dynamic dashboard cannot be scheduled for refresh. It must be scheduled manually. 

2. Your organization can have up to 5 dynamic dashboards for Enterprise Edition, 10 for Unlimited and Performance Edition, and 3 for Developer Edition.

3. Available in Unlimited, Enterprise and developer edition. 

4. You can ask your Account Executive for more information on increasing those limits. Note: this is a paid feature request.

5. Each dashboard can have up to 20 components.

Order of execution in Salesforce

Before Salesforce executes these events on the server, the browser runs JavaScript validation if the record contains any dependent picklist fields. The validation limits each dependent picklist field to its available values. No other validation occurs on the client side.

1. System Validation Rules.

2. Executes all before triggers.

3. Custom Validation rules.

4. Executes duplicate rules. If the duplicate rule identifies the record as a duplicate and uses the block action, the record is not saved and no further steps, such as after triggers and workflow rules, are taken.

5. Saves the record to the database, but doesn't commit yet.

6. Executes all after triggers.

7. Executes assignment rules.

8. Executes auto-response rules.

9.Executes workflow rules.

10.  If there are workflow field updates, updates the record again.

11.  If the record was updated with the workflow field update, it fires before and after triggers one more time (and only one more time) with standard validation rules. Custom validation rules, duplicate rules, and escalation rules are not run again.

Note:
If there were multiple field updates which updated the record, before and after triggers with standard validation rules will be fired only one time.

12. Executes processes and flows launched via processes and flow trigger workflow actions. When a process or flow executes a DML operation, the affected record goes through the save procedure.

13. Executes escalation rules.

14. Executes Entitlement Rules.

15. If the parent record is updated, and a grand-parent record contains a roll-up summary field or is part of a cross-object workflow, performs calculations and updates the roll-up summary field in the parent record. Grand-parent record goes through save procedure.

16. If the record contains a roll-up summary field or is part of a cross-object workflow, performs calculations and updates the roll-up summary field in the parent record. Parent record goes through save procedure.

17. Executes Criteria Based Sharing evaluation.

18. Commits all DML operations to the database.

19. Executes post-commit logic, such as sending email.

What are governor limits in Salesforce?

Governor limits are runtime limits enforced by the Apex runtime engine. Since 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

1. Memory
2. Database resources
3. Number of script statements to avoid infinite loops
4. Number of records being processed. If code exceeds a limit, the associated governor issues a runtime exception.

Because Apex runs in a multitenant environment, the Apex runtime engine strictly enforces a number of limits to ensure that runaway Apex doesn’t monopolize shared resources. If some Apex code ever exceeds a limit, the associated governor issues a runtime exception that cannot be handled.

The Apex limits, or governors, track and enforce the statistics outlined in the following tables and sections.

1. Per-Transaction Apex Limits
2. Per-Transaction Certified Managed Package Limits
3. Force.com Platform Apex Limits
4. Static Apex Limits
5. Size-Specific Apex Limits
6. Miscellaneous Apex Limits

Salesforce Interview questions with answers Part 7

1)What is look-up filter and how it is useful?

Lookup filter is used to filter records when we lookup for the records.
Used in Lookup dialogs.

http://infallibletechie.blogspot.com/2013/04/lookup-filter-in-salesforce.html

2)When a task is assigned to user through web to lead or web to case through assignment rules,where the tasks are appeared for that particular user?

Home page of the user.

http://infallibletechie.blogspot.com/2013/04/where-to-view-assigned-tasks-in.html

3)When a case is generated by an user through web to case,how or where a developer will provide solution case arised?


Email notification through trigger or through email alert Workflow rule.

4)what is the use of interfaces(in apex classes)?

An interface is like a class in which none of the methods have been implemented—the method signatures are there, but the body of each method is empty. To use an interface, another class must implement it by providing a body for all of the methods contained in the interface.

Interfaces can provide a layer of abstraction to your code. They separate the specific implementation of a method from the declaration for that method. This way you can have different implementations of a method based on your specific application.

http://www.salesforce.com/us/developer/docs/apexcode/Content/apex_classes_interfaces.htm

5)I have added an string 'updated' to all users in Account object through batch apex,now how to remove that 'updated'?

Run the below code in developer console

List<Account> acc =[SELECT Id, Name FROM Account];
for(Account a : acc)
{
    a.Name = a.Name.removeEnd('Updated');
    update a;
}

Where to view assigned Tasks in Salesforce?

To view assigned tasks, go to your home page.

Lookup filter in Salesforce

Lookup filter is used to filter records when we lookup for the records.
Used in Lookup dialogs.

In the above example, I have created a Lookup relationship(Member is parent and Interest is child).
Here, whenever we create Interest record, it will fetch only Member records with Status "New".

To add data to custom setting fields:

1. Click Setup --> Develop --> Custom Settings, then click Manage next to a custom setting. Or from the detail page for a custom setting, click Manage.

 2. Click New or Edit next to an existing data set.

 3. Add or change data.

1. For custom settings that are lists:

   1. Specify or change the name for the data set. This name is used by Apex, formula fields, and so on.
   2. Enter or change data for all fields.
   3. Click Save.
   For custom settings that are hierarchies:

   1. For the default organization level values, enter or change the data for the fields. The default organization location is automatically populated.
   2. For profile or user level values, select either Profile or User from the Location picklist. Enter the name of the profile or user, or use the lookup dialog search. Then enter or change the data for the fields.
   3. Click Save.

Custom Settings in Salesforce

Custom settings are similar to custom objects and enable application developers to create custom sets of data, as well as create and associate custom data for an organization, profile, or specific user. All custom settings data is exposed in the application cache, which enables efficient access without the cost of repeated queries to the database. This data can then be used by formula fields, validation rules, Apex, and the SOAP API.

Check the below site for fetching data from Custom Settings

http://www.infallibletechie.com/2013/04/how-to-display-custom-setting-data.html

There are two types of custom settings:

List Custom Settings:

 A type of custom setting that provides a reusable set of static data that can be accessed across your organization. If you use a particular set of data frequently within your application, putting that data in a list custom setting streamlines access to it. Data in list settings does not vary with profile or user, but is available organization-wide. Examples of list data include two-letter state abbreviations, international dialing prefixes, and catalog numbers for products. Because the data is cached, access is low-cost and efficient: you don't have to use SOQL queries that count against your governor limits.

Hierarchy Custom Settings:

 A type of custom setting that uses a built-in hierarchical logic that lets you “personalize” settings for specific profiles or users. The hierarchy logic checks the organization, profile, and user settings for the current user and returns the most specific, or “lowest,” value. In the hierarchy, settings for an organization are overridden by profile settings, which, in turn, are overridden by user settings.

Limits in Custom Settings:

1. The total amount of cached data allowed for your organization is the lesser of these two values:
    i.  10 MB
    ii. 1 MB multiplied by the number of full-featured user licenses in your organization

2. Each Certified managed package gets its own separate limit in addition to your organization limit.

3. 300 fields per custom setting.

4. You can’t share a custom setting object or record.

5. No owner is assigned when a custom setting is created, so the owner can’t be changed.

6. Custom settings are a type of custom object. Each custom setting counts against the total number of custom objects available for your organization.

As a subtab of in Service cloud console in Salesforce

" As a subtab of " is used to decide how records display when they are selected from outside of primary tabs or subtabs.

For example, when users select cases from list views, search results or screen pops, you can select cases to display as primary tabs or as subtabs on parent records, such as accounts.

Sample " As a subtab of ":

 

In the above example, for Case I have selected as "As subtab of Account Name(Account)".

Sample Case in Account:

Service Cloud console in Salesforce

A Service Cloud console is an app that’s designed for users in fast-paced environments who need to find, update, and create records quickly. It improves on the Console Tab by letting you:

• Work with fewer clicks and less scrolling
• Limit switching between pages
• Use keyboard shortcuts to perform actions
• Easily spot important fields on records
• See records and their related items as tabs on one screen so that you never lose context or navigate too far from a record
• Jot notes on each record in an interaction log
• See visual indicators in real time when lists and records are changed by others
• Solve cases by quickly scanning Salesforce Knowledge articles
• Access a SoftPhone for Salesforce CRM Call Center in a footer instead of a sidebar
• Chat with customers in real time using Live Agent

Assignment Rule Entries in Salesforce

In Assignment Rule Entries in Salesforce, if the first rule is satisfied, rest of the rules will be checked.

Consider the below example

Rule 1:
If Case Reason contains 'Other' and Case Description is equal to 'Issue', then the case should be assigned to Magulan Pandian.

Rule 2: 

If Case Reason is equal to 'Other', then case should be assigned to Test.

Rule 3:

If Case Description is equal to 'Issue', then case should be assigned to Test.

If Rule 1 is satisfied, Rule 2 and Rule 3 will not be executed. So, be careful in Rule Entries order of execution.

Sample Output:

 

 

It has been assigned to Magulan Pandian, because Rule 1 is satisfied, other Rules 2 and 3 are not executed.
