What kind of relationship you have,if it is a Master Detail it would delete the child records automatically.
the below works assuming it's not a m-d relationship, in which case you don't need any code
trigger deleteChildrenOnParentDelete on Parent_Object__c (before delete) { List<Parent_Object__c> parentList = new List<Parent_Object__c>([SELECT Id FROM Parent_Object__c]); Map<Id,Parent_Object__c> childMap = new Map<Id,Parent_Object__c>(); For(Parent_Object__c c: parentList) { childMap.put(c.ID,c); } List<Child_Object__c> childList = new List<Child_Object__c>(); For(Child_Object__c c: [select Id,Parent_Object__c from Child_Object__c where Parent_Object__c IN: childMap.Keyset()]) { childList.add(c); } Delete childList; }i use the lookup relationship for parent-child.......
if(Trigger.isDelete)
{
Set setdeleteId = new Set();
for(Contact delc : trigger.old)
{
setdeleteId.add(delc.Id);
List delcont =[Select Id,Contact__c from CustomDetails__c where Contact__c=' '] ;
delete delcont;
}
}
