Dev2India Apex trigger : Creating child records
I am using the below code to create child record, based on certain conditions. Howeever, in the below code , do not want to check the values in trigger.old. I want to query for the child records if those exists are not, then to create the child record. If child record exist ,then do not create the child record and if not then create the child record.
trigger createSplitCommissionOnOpportunityX on Opportunity (after insert, after update) {
List<Split_Commissions__c> SCToInsert = new List<Split_Commissions__c> ();
for (Opportunity o : Trigger.new) {
if ( ((Trigger.isInsert) ||
(Trigger.isUpdate) && (Trigger.oldMap.get(o.id).StageName != 'Closed Won')) &&
(o.StageName == 'Closed Won') )
{
Split_Commissions__c SC = new Split_Commissions__c ();
sc.Opportunity_Name__c = o.id;
SCToInsert.add(sc);
}//end if
}//end for o
//once loop is done, you need to insert new records in SF
// dml operations might cause an error, so you need to catch it with try/catch block.
try {
insert SCToInsert;
} catch (system.Dmlexception e) {
system.debug (e);
}
}
Please suggest the code how to query to check in the code if child exists or not.
Much appreciated.

You have to use inner query to check child record of opportunity.
see below code:
Apex Trigger:
trigger createSplitCommissionOnOpportunityX on Opportunity (after insert, after update) {
List<Split_Commissions__c> SCToInsert = new List<Split_Commissions__c>();
List<Opportunity> lstOpp = [select id, StageName, (select id from Split_Commissionss__r) from Opportunity where id in: trigger.newmap.keyset()];
for (Opportunity o : lstOpp) {
if ( ((Trigger.isInsert) || (Trigger.isUpdate) && (Trigger.oldMap.get(o.id).StageName != 'Closed Won')) && (o.StageName == 'Closed Won') && o.Split_Commissionss__r.size == 0){
Split_Commissions__c SC = new Split_Commissions__c ();
sc.Opportunity_Name__c = o.id;
SCToInsert.add(sc);
}//end if
}//end for o
//once loop is done, you need to insert new records in SF
// dml operations might cause an error, so you need to catch it with try/catch block.
try {
insert SCToInsert;
} catch (system.Dmlexception e) {
system.debug (e);
}
}
