Trigger to update New Lead count

Hi There,

 


Can any one please tell me where Iam going wrong in this trigger?

 

 

trigger calculateNewLeads on Campaign (before update) {
    
    List<Lead> leads=[SELECT Id, lead_source_details__c FROM Lead WHERE lead_source_details__c IN :Trigger.new];
    
    for (Campaign c : Trigger.new) {
        c.trigger_new_field__c=leads.size();
    }
    
    
}

 

Followintg is the error message - Error: Compile Error: Invalid bind expression type of SOBJECT:Campaign for column of type String at line 3 column 100.

 

Request all to kindly help.

 

Thanks,

George

Is this lead_source_details__c field is a look up field to Campaign?

You can do one thing

 

List<ID> ids = new List<Id>();

for(Campaign cam : Trigger.new){

ids.add(cam.id);

}

List<Lead> leads=[SELECT Id, lead_source_details__c FROM Lead WHERE lead_source_details__c IN :ids];

use Trigger.new.keyset() in your query

 

List<Lead> leads=[SELECT Id, lead_source_details__c FROM Lead WHERE lead_source_details__c IN :Trigger.new.keyset()];

hi george,

 

You have to update your SOQL query with below.

 

List<Lead> leads=[SELECT Id, lead_source_details__c FROM Lead WHERE lead_source_details__c IN :Trigger.newmap.keyset()];

Hi George,

 

I tried following trigger and it worked absolutely fine for me . In last reply you mention this trigger is suppose to update new lead records but actually this trigger is updating "trigger_new_field__c" field in campaign object .

 

Code : 

 

trigger calculateNewLeads on Campaign (before update) {

List<Lead> leads=[SELECT Id, lead_source_details__c FROM Lead WHERE lead_source_details__c IN :Trigger.newmap.keyset()];

for (Campaign c : Trigger.new) {
c.trigger_new_field__c=string.valueof(leads.size());
}}

 

Please comfirm your requirement..

 

Regards
