Hello everybody,

I am trying to build a simple Apex trigger that updates a Lead field upon its deletion, or more correctly just before it gets deleted. The scope for this, is that this field update fires another process, so I am actually not even sure if this will work the way I am anticipating, but since I am learning more about Apex triggers, it could still be an valuable exercise.

Here is a draft of my trigger, which unfortunately is not correct

trigger my_delete_trigger on Lead (before Delete) {
   
for (Lead trigger.old){update custom_id__c = a0g5800000A4O0Z;}
     } 

Any help on this would be greatly appreciated.

I used the following apex trigger in order to count the amount of open and closed tasks on opportunities.

trigger CountTask on Task (after insert, after update) {
    
    public List<Task> ltask1 = new List<Task>();
    public id oppid;
    public integer inp=0;   
    public integer inr=0;
    for(Task t:Trigger.New){
        oppid = t.WhatId;
        system.debug('oppid'+oppid);
        
    }
    ltask1 = [select id,Status from task where whatid=:oppid];
    system.debug('oppsize'+ltask1.size());
    
    
    for(task t:ltask1){
        if(t.Status!='Abgeschlossen'){
            inp = inp+1;
        } else{
            inr = inr +1;
        }                
    }
    List<Opportunity> opp = new List<opportunity>();    
    List<opportunity> op = [select id from Opportunity where id = :oppid];
    system.debug('oppsize'+op.size());
    for(opportunity o: op){
        o.Open_Tasks__c = inp;
        o.Closed_Tasks__c = inr;
        opp.add(o);  
    }
    if(opp.size()>0){
        update opp;
    }        
    system.debug('No of Tasks'+inp+inr);       
}

when trying to create a task on an opportunity I get the the following error:

CountTask: execution of AfterInsert caused by: System.DmlException: Update failed. First exception on row 0 with id 0065800000MKq82AAD; first error: INVALID_CROSS_REFERENCE_KEY, invalid cross reference id: [] Trigger.CountTask: line 32, column 1

Since I am a bit new with Apex triggers, could someone explain, what do I need to do to fix this?
Thank you very much in advance

Hello everybody,

I am trying to build a simple Apex trigger that updates a Lead field upon its deletion, or more correctly just before it gets deleted. The scope for this, is that this field update fires another process, so I am actually not even sure if this will work the way I am anticipating, but since I am learning more about Apex triggers, it could still be an valuable exercise.

Here is a draft of my trigger, which unfortunately is not correct

trigger my_delete_trigger on Lead (before Delete) {
   
for (Lead trigger.old){update custom_id__c = a0g5800000A4O0Z;}
     } 

Any help on this would be greatly appreciated.

I used the following apex trigger in order to count the amount of open and closed tasks on opportunities.

trigger CountTask on Task (after insert, after update) {
    
    public List<Task> ltask1 = new List<Task>();
    public id oppid;
    public integer inp=0;   
    public integer inr=0;
    for(Task t:Trigger.New){
        oppid = t.WhatId;
        system.debug('oppid'+oppid);
        
    }
    ltask1 = [select id,Status from task where whatid=:oppid];
    system.debug('oppsize'+ltask1.size());
    
    
    for(task t:ltask1){
        if(t.Status!='Abgeschlossen'){
            inp = inp+1;
        } else{
            inr = inr +1;
        }                
    }
    List<Opportunity> opp = new List<opportunity>();    
    List<opportunity> op = [select id from Opportunity where id = :oppid];
    system.debug('oppsize'+op.size());
    for(opportunity o: op){
        o.Open_Tasks__c = inp;
        o.Closed_Tasks__c = inr;
        opp.add(o);  
    }
    if(opp.size()>0){
        update opp;
    }        
    system.debug('No of Tasks'+inp+inr);       
}

when trying to create a task on an opportunity I get the the following error:

CountTask: execution of AfterInsert caused by: System.DmlException: Update failed. First exception on row 0 with id 0065800000MKq82AAD; first error: INVALID_CROSS_REFERENCE_KEY, invalid cross reference id: [] Trigger.CountTask: line 32, column 1

Since I am a bit new with Apex triggers, could someone explain, what do I need to do to fix this?
Thank you very much in advance

Good Morning, 

Below is a trigger I wrote to sum the number of activities on a given opportunity. I am getting an error at line 20, unexpected token: 'Map'.

Any ideas on what I could be doing wrong? This is the first trigger I have written so go easy on me :)

trigger CountTasks on Opportunity (before update) {
     
    // Put all Opportunities into a Set
    Set<string> allOppIDs = new Set<string>();
    for (Opportunity newOpp : Trigger.new) {
        allOppIDs.add(newOpp.ID);
        System.debug('ID added: ' + newOpp.ID);
    }
     
    //Query All Tasks to find Tasks with matching IDs
    List<task> allTasks = [SELECT Id, Status, WhatID from Task
                           WHERE WhatID IN :allOppIDs];
    System.debug('allTasks is ' + allTasks.size());
    // Create a Map that lets you search for Tasks by their ID - faster than SOQL each time
     
    List<string> TaskArray = new List<string>(); //All Tasks
    List<string> IDToTaskMapOpen = new List<string>(); //usedforOpenTasks
    List<string> IDToTaskMapClosed = new List<string>(); //usedforClosedTasks
     
    Map<string nteger=""> elCountAll = new Map<string nteger="">(); //Count of All Tasks
    Map<string nteger=""> elCountOpen = new Map<string nteger="">(); //Count of Open Tasks
    Map<string nteger=""> elCountClosed = new Map<string nteger="">(); //Count of Closed Tasks
     
     
     
    for (Task u : allTasks) {
        if (u.Status != 'Completed' ) {
            IDToTaskMapOpen.add(u.WhatID);
            System.debug('Added Open Task');
             
        }
        if (u.Status == 'Completed') {
            System.debug('Added Completed Task');
            IDToTaskMapClosed.add(u.WhatID);
             
        }
        TaskArray.add(u.WhatID);
    } 
     
    System.debug(allTasks.size());
    System.debug(IDToTaskMapOpen.size());
    System.debug(IDToTaskMapClosed.size());
     
     
     
    // Get the matching tasks from the Map - and count Status
    //Start with our Opportunity
    for (Opportunity newOpp : Trigger.new) {
         
        //Count all Tasks
        for(String key : TaskArray)
        {
            if(!elCountAll.containsKey(key)){
                elCountAll.put(key,0);
            }
            Integer currentInt=elCountAll.get(key)+1;
            elCountAll.put(key,currentInt);
        }
         
         
        //Count all Open Tasks
        for(String key1 : IDToTaskMapOpen)
        {
            if(!elCountOpen.containsKey(key1)){
                elCountOpen.put(key1,0);
            }
            Integer currentInt1=elCountOpen.get(key1)+1;
            elCountOpen.put(key1,currentInt1);
        }
         
        //Count all Closed Tasks
        for(String key2 : IDToTaskMapClosed)
        {
            if(!elCountClosed.containsKey(key2)){
                elCountClosed.put(key2,0);
            }
            Integer currentInt2=elCountClosed.get(key2)+1;
            elCountClosed.put(key2,currentInt2);
        }
         
         
        //Finally update the record
        //All Activities
        newOpp.AllTasks__c = elCountAll.get(newOpp.ID);
         
        //Open & Not Started Tasks
        newOpp.Open_Tasks__c = elCountOpen.get(newOpp.ID);
         
        //Closed Tasks
        newOpp.Closed_Tasks__c = elCountClosed.get(newOpp.ID);
         
    }
     
     
}
