Sytanx errors: Create Batch Class to Process Stagings and insert Opportunity

Question

I am working on a task. To understand my issue let me describe what I am doing.

---

Object: staging__c

Fields:

Individual_or_Organization__c (Text)

Orgganization_Name__c

First_Name__c

Last_Name__c

Postal_Code__c

Date_Recieved__c (Date)

Amount__c (Currency)

Error_Message__c (Long Text)

Description__c

Requirement:

Case1. If Individual_or_Organization__c==I ,

Search for existing contact with matching FistName , LastName and Postal Code. If contact not found then create new contact.

If staging record contains value in Orgganization_Name__c and Postal_Code__c Fields then search for account with matching name and postal code. If account found then link contact record with this account.

Create new opportunity record for that contact

Case2. If Individual_or_Organization__c==O

Search for existing Account with matching Orgganization_Name__c and Postal Code. If Account not found then create new account.

If staging record contains value in Last_Name__c and Postal_Code__c Fields then search for contact with matching firstname,lastname and postal code. If contact found then link contact record with the account.

Create Opportunity record for account

Field Mapping for Opportunity:

OpportunityName = Account Name or Contact Name+CloseDate

CloseDate = Date_Recieved__c

Amount = Amount__C

Description=Description__c

As you saw the requirement I am working on "condition 1" I wrote a batch class for same but still it raising few errors please have a look at my code

global class BatchAssignment implements Database.Batchable<sObject>{
    global Database.QueryLocator start(Database.BatchableContext BC){     
        return Database.getQueryLocator([SELECT Id, Individual_or_Organization__c,Orgganization_Name__c,First_Name__c,Last_Name__c,Postal_Code__c,Date_Recieved__c,Amount__c,Error_Message__c,Description__c 
                                         FROM staging__c]);
    }

                        }
                    }
                }catch(Exception ex) {

                }

            }
            
        }
        return linkContactList;
    }
    
    global void finish(Database.BatchableContext BC){        
    }

These are the errors I am unable to fix

Answer 1

There were many errors in the code such that you are not looping the scope in the execute method, there were some issues regarding the open and close braces { and } and also ,. I have updated the code now i don't see any errors.

global class BatchAssignment implements Database.Batchable<sObject>{
    global Database.QueryLocator start(Database.BatchableContext BC){     
        return Database.getQueryLocator([SELECT Id, Individual_or_organization__c ,Orgganization_Name__c,First_Name__c,Last_Name__c,Postal_Code__c,Date_Recieved__c,Amount__c,Error_Message__c,Description__c 
                                         FROM staging__c]);
    }    
    
  global void execute(Database.BatchableContext BC, List<staging__c> scope){
        List<Opportunity> newOpptyList = new List<Opportunity>();
      for(staging__c sc:scope){
        if(sc != null && sc.Individual_or_organization__c  == 'I') {
            Account objAccount = searchAccount(sc);
            if(objAccount != null) {
                List<Contact> linkContactList = searchContact(objAccount, sc);
                system.debug('contact'+linkContactList);
                try{
                    if(linkContactList != null && !linkContactList.isEmpty()) {
                        upsert linkContactList;

Answer 2

There are few compilation issue I see right from your code above.

1. I see no closing curly braces at the end of the file.
2. In Method searchAccount and searchContact params are list but your are expecting Single object while declaring the method.
3. Method searchAccount does not have any return statement in else as the first return statement is inside if block.
4. In method searchContact while adding it to linkContactList you missed a comma , after this scope.Postal_Code__c

I may have not identified more minutely, but These all are compilation issues which can be fixed from your end.
