meet.siva Remove duplicates using Trigger
Hi,
I have employee_id__c field in custom object Opportunity_CRM__c. It has duplicate values as single employee can create multiple opportunities. I have to insert unique employee_id from Opportinity_CRM__c into employee_id__c field in another custom object test__c. Insert operation is successful using trigger below. But i cant eliminate duplicate values. So plz help me.
trigger employee_id on Opportunity_CRM__c (after insert)
{
List<Test__c> test = new List<Test__c>();
Set<Opportunity_CRM__c> myset = new Set<Opportunity_CRM__c>();
List<Opportunity_CRM__c> mylist = new List<Opportunity_CRM__c>();
List<Opportunity_CRM__c> result = [select Employee_ID__c from Opportunity_CRM__c];
for (Opportunity_CRM__c s : Trigger.new)
{
if (myset.add(s))
{
Test__c mytest = new Test__c();
mytest.Employee_ID__c = s.Employee_ID__c;
test.add(mytest);
}
}
try
{
insert test;
}
catch (system.Dmlexception e)
{
system.debug (e);
}
}
Finally i gat my trigger to remove duplicates..Its working perfectly
trigger employee_id on Opportunity_CRM__c (after insert)
{
List<AggregateResult> result = [Select Employee_ID__c from Opportunity_CRM__c group by Employee_ID__c];
List<string> mylist = new List<string>();
List<Test__c> test = new List<Test__c>();
Set<Test__c> myset = new Set<Test__c>();
for (Opportunity_CRM__c s : Trigger.new)
{
for(AggregateResult ar : result)
{
Test__c mytest = new Test__c();
mytest.Employee_ID__c = string.valueOf(ar.get('Employee_ID__c'));
if(myset.add(mytest))
{
test.add(mytest);
}
}
}
try
{
insert test;
}
catch (system.Dmlexception e)
{
system.debug (e);
}
}

Hi
I believe you could delete the record with an @future, but maybe the ideal solution is to assign the duplicates to a "duplicate queue" and then do a bulk delete out of that queue. Just a thought.
Consider doing a SELECT into this TEST object and see if you get a record. If you do get a record, don't do the insert insert. Use a list, just in case no records come back.
Maybe load this test object into a map and look up in the map. That may same some DML operations.
Hey i am not able to achieve the objective. Can any one share any code to complete the task? Please. It will be helpful.
