How to get Record Type developer name in Apex ?

Hi All,

Before summer 18, we used to write SOQL query to get developer name of a particular record type, now SOQL query is not required. 

This is my earlier post where recordtypeinfo method has been explained. What can we do using those methods.

1. How can we get Record Type Id of an object ?

    a.  Lets assume we know the record type name. say its "Inquiry".

Id objectRecordTypeId = Schema.SObjectType.CASE.getRecordTypeInfosByName().get('Inquiry').getRecordTypeId();
System.debug('objectRecordTypeId ---'+objectRecordTypeId ); 

    b.  Lets assume we know the record type developer name, say its "DevInquiry".

Id objectRecordTypeId = Schema.SObjectType.CASE.getRecordTypeInfosByDeveloperName().get('DevInquiry').getRecordTypeId();
System.debug('objectRecordTypeId ---'+objectRecordTypeId );

2.  How can we get record type developer name ? 

     a. Lets assume we know the record type name. say its "Inquiry".

String developerName = Schema.SObjectType.Case.getRecordTypeInfosByName().get('Inquiry').getDeveloperName();

Same code can be broken into following.

String recordTypename = 'Inquiry';

Schema.DescribeSObjectResult caseDesribe = Schema.SObjectType.Case;
Map<String,Schema.RecordTypeInfo> rtMapByName = caseDesribe.getRecordTypeInfosByName();
Schema.RecordTypeInfo rtByName =  rtMapByName.get(recordTypename);
String RecordTypeDeveloperName = rtByName.getDeveloperName();
System.debug('RecordTypeDeveloperName --'+RecordTypeDeveloperName ); 

  b.  Lets Assume we know recordType id.

String developerName = Schema.SObjectType.Case.getRecordTypeInfosById().get('012w0000000kc2XAAQ').getDeveloperName();

Please let me know if you have any confusion, I would be happy to help.

How to use includes operator in query filter ?

Hi All,

It has been a long time, there is no post in salesforce4u, I am apologizing for being so late, now I am assuring you, there will be at least one post in each month.

We will start with the simple one, Last week I faced one query exception "expecting left parentheses, found ':'",  Let me share how did I resolve that issue.

The requirement was just filtering records using multi-select picklist values. What exactly will come to a developer mind ??  Use the following operator to accomplish.

1. LIKE - It will be used for normal string/text field filter and it's a partial match.
2. CONTAINS - It is not being used at all in SOQL
3. INCLUDES - This is the best one to use for this requirement.

How to use INCLUDES operator in the SOQL query.

Below is the code snippet to filter Account based on value  ( 'Agriculture','HR' ).

Static Querry
List<Account> accList = [Select id,name,LOB__c from Account where LOB__c INCLUDES ('Agriculture','HR') ];
System.debug('accList ---'+accList[0]);

Dynamic Query

set<String> lobSet = new Set<String>{'Agriculture','HR'};
System.debug('lobSet ---'+lobSet );

String queryFilter = '';
For(String str :lobSet ){
   queryFilter += queryFilter == '' ? '(\''+str+'\'' : ','+ '\''+str+'\'';
queryFilter += ')';
System.debug('queryFilter ---'+queryFilter );

String sQuery = 'Select id,name,LOB__c from Account where LOB__c INCLUDES  '+queryFilter;
System.debug('sQuery ---'+sQuery );
List<Account> accListDynamicQueryResults = Database.query(sQuery);
System.debug('accListDynamicQueryResults ---'+accListDynamicQueryResults );
