How to get the Recordtype Id using Dynamic Apex

Normally to get the RecordtypeId for any sObject we use SOQL and it will count against your limit. So below method will bypass the need of SOQL Query.

Map<String, Schema.SObjectType> m = Schema.getGlobalDescribe() ;

Schema.SObjectType s = m.get('API_Name_Of_SObject') ;

Schema.DescribeSObjectResult cfrSchema = s.getDescribe() ;

Map<String,Schema.RecordTypeInfo> RecordTypeInfo = cfrSchema.getRecordTypeInfosByName();

Id rtId = RecordTypeInfo.get('Record Type Name').getRecordTypeId();

How to write the “Where” clause in SOQL when GroupBy is used for aggregate functions

We cannot use the “Where” clause with GroupBy for aggregate functions like SUM() instead we will need to use the “Having Clause“.

Example : Get all the opportunity where more than one record exists with same name and name contains “ABC”.

SELECT COUNT(Id) , Name FROM Opportunity GROUP BY Name Having COUNT(Id) > 1 AND Name like '%ABC%'

Explain difference in COUNT() and COUNT(fieldname) in SOQL.

COUNT()

COUNT() must be the only element in the SELECT list.

You can use COUNT() with a LIMIT clause.

You can’t use COUNT() with an ORDER BY clause. Use COUNT(fieldName) instead.

You can’t use COUNT() with a GROUP BY clause for API version 19.0 and later. Use COUNT(fieldName) instead.

COUNT(fieldName)

You can use COUNT(fieldName) with an ORDER BY clause.

You can use COUNT(fieldName) with a GROUP BY clause for API version 19.0 and later.

Read here in more detail about COUNT() and COUNT(fieldname)

You want to display the Encrypted field on Visualforce and you are using component apex:outputText. Will it work for Encrypted fields

Encrypted custom fields that are embedded in the <apex:outputText> component display in clear text. The <apex:outputText> component doesn’t respect the View Encrypted Data permission for users. To prevent showing sensitive information to unauthorized users, use the <apex:outputField> tag instead.

How to display the formatted number / date in Visualforce ? Which component should be used

Use component “<apex:outputText>”.

Example : Format the number into currency.

<apex:outputtext value="{0, number, 000,000.00}">

<apex:param value="{!valFromController}" />

</apex:outputtext>

<apex:outputtext value="{0, number, ###,###.00}">

<apex:param value="{!valFromController}" />

</apex:outputtext>

If IE9 is not working with your custom visualforce page then how to tell your visualforce code to run in IE8 compatibility mode

Add following metatag to pages:

Onchange event does not work with in IE9. How to resolve this error

Onchange event does not work with <apex:actionsupport> in IE9. How to resolve this error

If we hide the Header on Visualforce page then it creates lots of problem in IE9. I think there are few java-script library loaded by Header of Salesforce which makes IE9 compatible. So the best solution is to enable the Headre by using “showHeader=true” in Apex page.

How to add the Document Header in Visualforce page

Directly there is no way to add the document type in visualforce. However in most of the cases IE9 does not work with Visualforce pleasantly. And then we need to add the Document type in header. So following workaround will work.

<apex:outputText

escape="false"

value="{!'<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Strict//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd\">'}"/>

<html>

<head>

</head>

</html>

</apex:page>
