Using sobjects in trigger

Hello all- 

I have a scenario where the three objects trigger have relatively same logic for beforeInsert and beforeUpdate. Even the fields of these objects that i use in trigger are same. this is my below code. i want to use sobject so that i dont mention the object name Bill_To__c in the below code. Instead I use sobject so that my other two objects Sold_To__c and Running_Account__c can use the same trigger.  Can anyone help?

public static void relateWCSSToAccount(Lis<Bill_To__c> wcssList,Map<Id,Bill_To__c> oldMap)  {
        List<String> guids = new List<String>();
        Map<String,Id> accountMap = new Map<String,Id>(); 
        for(Bill_To__c wcss:wcssList)
          {
           // In case of Update, Add GUID when trigger old map GUID is not equal to trigger new list GUID.
           if(oldMap!=null && oldMap.size()>0)
           {
            if(wcss.GUID__c!=(oldMap.get(wcss.Id).GUID__c))
              guids.add(wcss.GUID__c);
           }
           // Incase of insert; get the new GUIDs
           if(wcss.GUID__c!=null)
           {
            guids.add(wcss.GUID__c);
           }
          }
         
          if(guids.size()>0)
          {
            //Find matching accounts based on GUID
           for(Account a : [SELECT Id,GUID__c FROM Account WHERE GUID__c in:guids])
           {
            accountMap.put(a.GUID__c,a.Id);
           }
          }
          if(accountMap!=null && accountMap.keyset().size()>0)
          {
           // Iterate through Trigger.New list of WCSS
           for(WCSS_Bill_To__c wcssNew : wcssList)
           {
            if(wcssNew.GUID__c!=null)
            {
             if(accountMap.get(wcssNew.GUID__c)!=null)
              {
               // Update Account on each WCSS_Bill_To_c object.
                wcssNew.Account__c = accountMap.get(wcssNew.GUID__c);
              }
            }
           }
          }
       }

You won't be able to use the same trigger, as the trigger is defined on a specific object and action(s).  You'll need to move your code out to an external class that each of the triggers delegate to.  You can pass the records through as generic sobjects, rather than named sobject types, and you can get and set field values through the Dynamic DML syntax.  There's more information on this at:

Hi Priyanka,

Please find below the code edited to handle sObject. 

ublic static void relateWCSSToAccount(List<sObject> wcssList,Map<Id,sObject> oldMap)  {
        List<String> guids = new List<String>();
        Map<String,Id> accountMap = new Map<String,Id>();
        for(sObject wcss:wcssList)
          {
           // In case of Update, Add GUID when trigger old map GUID is not equal to trigger new list GUID.
           if(oldMap!=null && oldMap.size()>0)
           {
            if(wcss.get('GUID__c')!=(oldMap.get(wcss.get('Id')).GUID__c))
              guids.add(wcss.GUID__c);
           }
           // Incase of insert; get the new GUIDs
           if(wcss.get('GUID__c')!=null)
           {
            guids.add(wcss.get('GUID__c'));
           }
          }
        
          if(guids.size()>0)
          {
            //Find matching accounts based on GUID
           for(Account a : [SELECT Id,GUID__c FROM Account WHERE GUID__c in:guids])
           {
            accountMap.put(a.GUID__c,a.Id);
           }
          }
          if(accountMap!=null && accountMap.keyset().size()>0)
          {
           // Iterate through Trigger.New list of WCSS
           for(Bill_To__c wcssNew : wcssList)
           {
            if(wcssNew.get('GUID__c')!=null)
            {
             if(accountMap.get(wcssNew.get('GUID__c'))!=null)
              {
               // Update Account on each WCSS_Bill_To_c object.
                wcssNew.put('Account__c', accountMap.get(wcssNew.GUID__c));
              }
            }
           }
          }
       }

I have not tested this but this is the way it should be handled for sObjects. Hope this helps!

Please let me know if it works for you.

Thanks

I did something of this sort:

List<String> guids = new List<String>();
        Map<String,Id> accountMap = new Map<String,Id>(); 
        for(sobject s:soList)
          {
           Id id = (Id) s.get('Id');
           String guid = (String) s.get('GUID__c');
            // In case of Update, Add GUID when trigger old map GUID is not equal to trigger new list GUID.
           if(oldMap!=null && oldMap.size()>0)
           {
            String oldGuid = (String) oldMap.get(id).get('GUID__c');
            if(guid!=oldGuid)
            {
             guids.add(guid);
            }
           }
           // Incase of insert; get the new GUIDs
           if(guid!=null)
           {
            guids.add(guid);
           }
          }
         
          if(guids.size()>0)
          {
            //Find matching accounts based on GUID
           for(Account a : [SELECT Id,GUID__c FROM Account WHERE GUID__c in:guids])
           {
            accountMap.put(a.GUID__c,a.Id);
           }
          }
          if(accountMap!=null && accountMap.keyset().size()>0)
          {
           // Iterate through Trigger.New list of WCSS
           for(sobject so : soList)
           {
            String newGUID = (String) so.get('GUID__c');
            if(newGUID!=null)
            {
             if(accountMap.get(newGUID)!=null)
              {
               // Update Account on each WCSS_Bill_To_c object.
                so.put('Account__c',accountMap.get(newGUID));
              }
            }
           }
          }
       }
