How can we make batch class iterable in Salesforce?

Hi sushant,

We can make batch iterable by calling batch again inside finish method for more detail go through below code

global class iterablebatch implements Database.Batchable<sobject>{
global String Query;
global List<id>allObjIds ;
global string idInitials;
global iterablebatch(List<id>allObjectIds,String var ){
allObjIds=allObjectIds;
idInitials =var;
}
global Database.QueryLocator Start(Database.BatchableContext BC){
if (idInitials=='001')
query='SELECT Id,Name FROM Account WHERE Id in:allObjIds';
if(idInitials=='003')
query='SELECT Id,Name FROM Contact WHERE Id in:allObjIds';
if(idInitials=='006')
query='SELECT Id,Name FROM Opportunity WHERE Id in:allObjIds';
return Database.getQueryLocator(query);
}
global void execute (Database.BatchableContext BC,List<Sobject>scope){
Schema.SObjectType sObjectType =scope.getSObjectType();
String listType = 'List<' + sObjectType + '>';
List<SObject> castRecords = (List<SObject>)Type.forName(listType).newInstance();
castRecords.addAll(scope);
if (idInitials=='001'){

for(sobject obj:castRecords){
Account acc= (account) obj;

acc.Name='Algoworks1';
}}
if (idInitials=='003'){

for(sobject obj:castRecords){
contact con=(contact)obj;
con.LastName='Algoworks1';}
}
if (idInitials=='006'){

for(sobject obj:castRecords){
opportunity opp=(opportunity)obj;
opp.Name='Algoworks1'; }
}
update scope;
}
global void finish (Database.BatchableContext BC){
iterablebatch objc = new iterablebatch(allObjIds,'003');
iterablebatch objo = new iterablebatch(allObjIds,'006');

}
}

Hope it may helps
