Hi Suraj

Access tokens have a limited lifetime specified by the session timeout in Salesforce. If an application uses an expired access token, a “Session expired or invalid” error is returned. If the application is using the Web server or user-agent OAuth authentication flows, a refresh token may be provided during authorization that can be used to get a new access token.

For more info:https://developer.salesforce.com/docs/atlas.en-us.api_rest.meta/api_rest/intro_understanding_refresh_token_oauth.htm

Hi Suraj

Perform a string replace on the json string, the implications of this is unintended replacement of valid text inside a string, but this could be mitigated if the form of the json is as you've supplied "currency": "ABC" you could string replace:

jsonString.replace('"currency":', '"currency_x":');

To customize a flow’s look and feel or enhance its functionality, embed it in a Visualforce page. If your org has flows enabled for sites and portals, use the Visualforce page to deliver the flow to your Force.com site, portal, or community.

you can look  in to this for better understanding: https://developer.salesforce.com/docs/atlas.en-us.pages.meta/pages/pages_flows_adding.htm

Hi Suraj

Blob is a collection of binary data stored as a single object. You can convert this data type to String or from String using the toString and valueOf methods, respectively. Blobs can be accepted as Web service arguments, stored in a document (the body of a document is a Blob), or sent as attachments.

Blob Methods
The following are methods for Blob.
size()
Returns the number of characters in the Blob.
toPdf(stringToConvert)
Creates a binary object out of the given string, encoding it as a PDF file.
toString()
Casts the Blob into a String.
valueOf(stringToBlob)
Casts the specified String to a Blob.

Hi Suraj

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, flows, Apex, and the SOAP API.

You can use SOQL to query Custom Settings just like an object. Use a SQOL query to find the right value:

select yourfieldname from customsettingname
where fieldname = :someval and fieldname = :otherval

Suppose you have custom setting Games__c.

You can get the list of records through :
List<Games__c> mcs = Games__c.getall().values();

To get individual record 'My Games' of custom setting :
Games__c objGame = Games__c.getValues('My Games');

Hi Manpreet

a cursor is a reference to the the result set for a soql query.

Select Id, name, (select Id, name from contacts) from account

Will account for 2 open cursors.

The way out was to simplify the soql queries and break what we were trying to achieve in one batch apex class over 2 classes.

Hi Suraj

You can easily run into this error if you are trying to perform DML on setup and non-setup objects in the same transaction.

Non-Setup objects are standard objects like Account or any custom object.

Setup objects are Group1, GroupMember, QueueSObject, User2, UserRole, UserTerritory, Territory, etc..

For example, you cannot insert an account and then insert a user or a group member in a single transaction.

Test methods allow for performing mixed DML operations between the sObjects listed earlier and other sObjects if the code that performs the DML operations is enclosed within System.runAs method blocks. This enables you, for example, to create a user with a role and other sObjects in the same test.

Hoping it may help you:

Hi Suraj

You can use this code given below:

global class classname implements Database.Batchable<sObject>{
global Database.QueryLocator start(Database.BatchableContext batchcontext){
String query = 'select id,name from Account';
return Database.getQueryLocator(query);
}
global void execute(Database.BatchableContext batchcontext,list<Account> scope){
for(Account a:scope){
a.name = a.name.removeEnd('stringname');// If you appended string at last

a.name = a.name.removeStart('stringname');//If you appended String at start
update scope;
System.debug(scope);

}
global void finish(Database.BatchableContext batchcontext){}
}

Hi Suraj

If you write two triggers, there is no particular order of execution and one might run first and sometimes second. In order to control the triggers order of execution, many experts have built Trigger Templates,that basically allow developers to control the order of execution and also control when the trigger needs to be fired. Please take a look at the below blog, you can even search for "Trigger Template" and get many other posts

Hi Manpreet

In spring 12, Salesforce has come up with ability of SOQL to get records from position “X” instead of position “1” every time to help creating pagination feature.

Select Id, Name from Lead LIMIT 5 OFFSET 2

Above query will return 5 Lead records starting from record number 10 (5×2).

You can get more information by going through this link:https://developer.salesforce.com/blogs/developer-relations/2012/01/soql-offset-in-spring-12.html

Hi Manpreet

A perspective is a predefined layout of panels in the Developer Console Log Inspector.
When you perform a task in the Log Inspector, use a perspective that makes completing the task fast and easy. Every developer has a different style. For a list of out-of-the box perspectives, see Log Inspector.

To create a custom perspective or modify an existing perspective:

1. In the Developer Console, open a log in the Log Inspector.
2. Click Debug | View Log Panels and select the panels you want to include in the perspective.

For a list of available panels, see Log Panels. If you modify a perspective, an * is appended to the perspective name until it is saved.

#If you create a perspective that includes the Execution Log panel, you may want to include the Source panel.#

To save your changes, click Save Perspective. To create a new perspective, click Save Perspective As and enter a new name.

Hi Manpreet

First thing to remember is that "Worflow rule" is not a field type in salesforce. Workflow rule is the process automation tool that automate your business flow .
Formula field: it is a field type on salesforce that produce a read only ouptut. Sometimes u want some calculated value in a field lest say i want my total sell in day in one field then i can create one formula field on my object and i will write a formula that will calculate total sell .
The field included in formula field is called it's source.

Now there is a similarity between workflow and formula field.:
Whenever there is a change in the source field of formula field it automatically re-calculate its field value according to updated value in the source field.
In same fashion workflow can also do the field update.

one more thing formula field can't use the workflow but inside a workflow we use formula field.
there are only one criteria to update the value of formula field but for workflow u can define different kind of criteria.

Hope it will help you.

The default timeout is 10 seconds. A custom timeout can be defined for each callout. The minimum is 1 millisecond and the maximum is 120,000 milliseconds.

Hi Suraj

You can perform this operation by going through this code given below:

//Creating List of all account Ids
List<id> accIdsList = new List<id>() ;

//Creating set of all account Ids
Set<id> accIdsSet = new Set<id>() ;

//Fetching all accounts
List<account> accList = new List<Account>();

//Creating Map with account id as key and account record as value
Map<Id,Account> accountIdObjMap = new Map<Id,Account>([select Id,name,site,rating,AccountNumber from account limit 50000]);

//getting list of account using map.values method
accList = accountIdObjMap.values();

//getting set of account Id's using map.keySet method
accIdsSet = accountIdObjMap.keySet();

//getting list of account Id's using list.addAll method
accIdsList.addAll(accIdsSet);

To clarify, this method can only be used to generate Maps using Id of the object you are querying as the key. If you want to use a different value as the key, you will have to iterate over the list returned by your query and put values into a Map. For instance, if you wanted to use AccountId as the key, you would need to do something like this: List<Opportunity> oppList = [Select Id, AccountId from Opportunity]; Map<Id,Opportunity> accOppMap = new Map<Id,Opportunity>(); for(Opportunity o : oppList){ accOppMap.put(o.AccountId,o); }
